back to article Global warming is actually good for rainforests, say boffins

OK, so let's take it that global warming is coming: that temperatures are set to rise by easily 3°C by the end of the century. Disaster, right? The tropical rainforests - lungs of the planet - will die, CO2 levels will thus rise even faster, a runaway process will set in and planet Earth will be transformed into a baking …

      Fingers in ears, la, la, la, la

      Just how long do you think it would take to establish rainforests in other latitudes, as existing ones wilt and die? I'd estimate this is on the order of many hundreds of years, if not longer.

      Sure, the status quo a millenium from now might be hunky dory, but for the next few human generations....the outlook is not so good.

      'Course this assumes temps will rise in line with climate change lobby predictions, and (for the record) I think the hyperbole and exaggeration seen in most press releases means this is rather unlikely.

      (ahem. yes the fence has left some nasty splinters in my bum.)

        @Marky W "There is no evidence for enhanced aridity in the northern Neotropics." would seem to imply imply no significant "wilting and dying", don't you think?

    ... global warming means more chocolate?


    1. Tigra 07

      Woo Hoo! Chocolate!

      Looks that way =]

      Another nail in the IPCC coffin.

      If more plants and trees appear and spread when temperature increases because of carbon, then more plants and trees will soak up more carbon and again limit the temperature.

      Green taxes make no difference and don't help the planet as it can clearly look after itself in this way.

      1. AdamWill


        ...with the 'planet' error.

        I find it amusing that the climate change denial lobby and the crazy 'green' lobby speak as one when they talk about 'the planet'. No matter where you stand on the issue, let's make it clear: 'the planet' doesn't give a shit either way about global warming. 'The planet' is not the one with the problem. The one with the problem is *us*. Of course global warming isn't going to kill the planet. Of course 'the planet' will 'look after itself', whatever that means exactly; it's a pretty vapid question, because again, it depends on where you're standing. 'The planet' will continue to exist until it smashes into the sun or is destroyed by a giant asteroid or the Vogons or whatever else is going to happen zillions of years in the future. From the point of view of biological life, yeah, the planet will 'look after itself' in the sense that life adapts to changing conditions; raise the temperature by five degrees and over *the long run* life will continue, in some way. The temperate zones will move around a bit, grow, shrink, whatever. Different species will manage differently, some will thrive, some will die, some new ones will show up, etc.

        The little problem is exactly what this 'adjustment' means for people, given that we're present all over the place and we are, as individual units, pretty goddamn vulnerable to the effects of environmental change. Yeah, as a whole, people would probably get by even through some pretty extreme environmental changes. But getting by in the long run can also be looked at as 'quite a lot of us dying and the lucky ones having to make rather drastic changes to their entire civilization, sharpish'.

        So yeah, a biologist twenty million years in the future will probably say 'eh, big whoop, yeah, in the environmental adjustment period of the 21st century, blahblah' but if you're actually in the unfortunate position of *living through* said environmental adjustment period, things may look a bit hairier.

    I wonder how well that will go down with the treehuggers

    So now GW is actually going to be good for the rainforests ? Well that sounds logical, given that it is a well-known fact that the dinosaurs lived in a much warmer period than today. And what did the vegetarian dinosaurs eat ? Tons of plants. Every day. Which obviously meant that there had to be tons and tons of the stuff lying around to support all that munching.

    So yeah, rainforests will logically do fine.

    But how will the eco-preachers spin this one ? Oh, I know, they'll say the report is not from a reliable source, or the data is wrong, or any other of a dozen ad-hominem attacks.

    Still, the ripples continue to grow around the GW conflict without any end in sight.

      "So yeah, rainforests will logically do fine."

      Good for the rainforests on a geological scale and assuming there are not lots of pesky humans chopping them down yes. Did that 5C warming and 1000ppm CO2 happen quickly or over thousands of years... Hmmm lets think?

      How about good for our rainforests in the positions they are in now? Such a large global temperature change will surely massively effect the precipitation in rainforest regions? (Plus many other factors that might equalise to happy rainforests in a few millennia) I am no expert but a little common sense applied seems to change this from a global warming is good for the environment to err wait a moment lets think about it without the global warming blinkers on (Either kind)

      And yes the ripples of the Global Warming conflict continue to propagate in the medium of a million commentards lack of logic.

      Exactly what i was just thinking, and clearly they've already marked you down a bit.

      Even with new evidence every week, people who don't believe we cause global warming are silenced by idiots who can spin anything the way they want with absolutely no evidence that people indeed cause global warming.

      Despite so much evidence saying global warming is natural and not cause by people (the dinosaurs didn't have cars btw), the people who speak out are silenced by slurs and insults, including the ignoramus the other day who said they were tied to cigarette companies.

      So bring on the red arrows anyone who believes the dinosaurs had cars and planes to cause the last ice age and the periods of global warming through history!

        "Even with new evidence every week, people who don't believe we cause global warming are silenced by idiots who can spin anything the way they want with absolutely no evidence that people indeed cause global warming."

        I love this idea. Those who claim ACC is true are stupid, yet also amazingly gifted at spinning an apparent nothingness into a veritable end of days. So gifted, that the towering group intellect of the skeptics are foiled at every turn.

        It doesn't quite add up, does it.

        Perhaps the truth of the matter is that, although you see new evidence every week supporting your thesis (as brought to you by the man who will suffer no debate, and what does that tell you children?), substantially more evidence to the contrary is also brought to light every week. Of course, you choose not to see that evidence, but that's your problem. Don't make it mine, eh?

        "Despite so much evidence saying global warming is natural"

        Blah, blah, cite me a meta-analysis showing that the naysayers have more evidence than the yea-sayers. Without recourse to the flaccid "climate people are so stupid and intelligent that they've sewn up all the journals".

        "(the dinosaurs didn't have cars btw)"

        Well that's a fair point fairly made. You have clearly considered all the differences between the two scenarios before painstakingly working your way towards a very solid conclusion. It is, after all, obvious that a body could not undergo changes in temperature for different reasons. There could only be one cause. And since the dinosaurs didn't have cars, well cars can clearly have no effect on temperature!

        Of course things broke before there were cars, so I guess driving into something at 90mph is now considered to be perfectly safe too. Thank you, Brave Skeptical Thinkers, for saving us from the lying Newtonian idiot-scum.

                Can you prove E=MC2? Can you prove Darwinian evolution? No, you can't (science doesn't work that way). I presume that means you reject the Einstein conspiracy & the biology conspiracy too?

                Science works by proposing hypotheses, and by testing them. At any given moment, nothing in science is proven - we merely work with the best available hypothesis. That is its strength.

                The best available hypothesis on climate is that it is changing, and this is largely due to anthropogenic effects. Thos who dismiss this hypothesis, merely because it is unproven, display their ignorance of science.

                I used to be a practising scientist. I had books. If I wanted to know the answer to things, I would look in those books. Day in, day out. I did not run my own experiments to test the validity of Newton's Laws, I did not deduce everything from first principles.

                I know, I know, a few scientists disagree. But again, if you had actually done any science beyond A-Level, even just a year of shitology at The Croydon Institute of Excellence, you'ld know that ALL scientific theories have dissenters. I myself disagreed vehemently with the mainstream on EPRB and CHSH. I never once tried to call them stupid. I don't try to piss it all over the internet.

    the data

    It's hard to make a GW decision based on data because there's always some more data a long in a month or so to make you change you mind.

    It's easier to make a decision based on the behaviour of the preachers.

    Naturally, those I dis- agree with are ignorants repeating the doctrines of the dishonest.

    Of course, they think the same about me; so what was my real reason for my decision, I wonder...

      Facts, figures and things people forget

      Twenty years ago, a friend of mine completed her Environmental Science degree. She was somewhat disappointed, however: She wanted to do a thesis on weather cycles, but these were, apparently, too complex to map and intersections were too unpredictable. Instead she studied deer shitting in woods. Turns out they do. And in fields and anywhere else they happen to be.

      But she did note something, even back then. Actually, she noted several things:

      1) We are currently in an Ice age. We have been for a very long time and are due to emerge from it any day now. Seriously, we're actually overdue. Bit worrying there's no sign, isn't it? I mean, icecaps have to melt completely for us to be out of the ice age. (Just for reference, we're interglacial - the glaciers retreat, exposing the land. If they advance again, we're in trouble: They'll want their land back. And the lawn mower...).

      2) When we hit the 'flip' from ice age to temperate, we could well see Sabre toothed cats reappear. She likes cats. So do I. It would be fun watching people's reaction to the appearance of Sabre toothed cats again.

      More recently, with all this C02 business and 'Global warming' panic, she noted:

      3) They (the environmental scientists, that is) have been expecting this. It's in the course books, after all, so it's been published for 20+ years, along with predictions as to what we might see (refer to 2, above). Gee, I wonder what the Sabre toothed cats will look like this time. Are house cats teeth growing? Or are the ABC's our new feline overlords...

      4) Someone's having a laugh: Panic over C02? It's nothing: Methane is a more dangerous 'greenhouse' gas...

      5) Greenhouse gasses. How are they going to work, exactly? Oh, they hold heat in? But won't they reflect heat, too? After all, the normal temperature of the planet is 6 C. Anything above that is from the sun. Look, clouds at night keep the land beneath them warmer, but during the day they provide shade that keeps it cool. Won't greenhouse gasses do the same but on a global scale? Won't it all balance out in the end?

      6) Where are those Sabre toothed cats!

      And me? I sit there and listen and I wonder... all this data: Is it correct? What factors have they taken in to consideration. They are scientists, aren't they: They haven't changed anything or missed anything out. But it always bothered me that they don't mention this thing about the ice age: That permanent icecaps are actually bad for the planet, and at some point they really need to melt. That we need to move into a temperate age. Well, the planet does, anyhow: Man really isn't that important as far as the planet is concerned. Little more than an infestation, an irritation, a pest to be exterminated it when the time comes. And then I wonder about these claims about how much impact man has on all this... you know, I'm not convinced we're not seeing a natural change to the planet's temperature, and that the worst thing man could be doing is just making it happen a little faster...

      But hey, someone has to preach about the end of the world. Someone has to make money by scamming people through scare tactics. Someone has to be declared a heratic for pointing out the claims don't quite add up. And the bulk of us sit on, bemused, as people argue the world is flat/round/rhomboid/doomed.

      Anyway, I'm off to go look at those cats. They seem to be smiling. Big smiles with big teeth...

    Totally irrelevant

    It doesn't matter how good (or bad) global warming is for tropical rainforests if they've all been chopped down before the change in climate anyway.

    1. Charles Manning

      We'll have to chop the stuff down

      CO2 is plant food. Plants grow faster when it is warmer. It strikes me that if we don't keep chopping the forests down we'll soon end up with the world overrun with trees.

      What takes the biscuit is that so many Europeans - particularly Poms - complain about how the tropics is being deforested yet they killed off all their trees hundreds of years ago. If the UK wants to really reverse deforestation then they should start in their own back yard and restore the forests to what they were. Rip up the cities, farms etc and replant with trees. Oh, then reintroduce wolves and bears.

      Of course the UK won't do that. They want to keep what they've got and have the third world make all the sacrifices.

    Change for SIX BILLION

    Right, climate change might be good for some rainforests?

    At the same time when you discuss change in the climate, you need to factor in the SIX BILLION people that need to adapt.

    If there were a thousand people on this earth, you can move them around when climate changes. But with SIX BILLION+, you do not get the option.

  8. Shakje

    I didn't think anyone was saying high temperatures would kill things

    but that the rate of change of those temperatures would lead to conditions that would make it difficult for such things to survive. A pertinent question might be "how long did it take for the temperature to reach that level?" Go look at an estimated graph of the temperature variation for that period and look at just how long it took to get to that level.

  9. Sir Sham Cad

    Not the issue

    Climate Change is not even close to the biggest threat to the rainforests nor can the rapid loss of rainforest habitat and subsequent loss of species be significantly attributed to climate change.

    It can be significantly attributed to chainsaws and JCBs for both legal and illegal logging and clearing.

    I'm a believer in climate change and that mankind's activities are contributing, at least in part. I also believe that our scientific models need a lot more work if we're to understand the mechanisms of CC and make reasonably accurate assessments of impact.

    I also believe that CO2 emissions and contributions to climate change are the least of the ways in which we are fucking up the planet and causing extinctions. Let's have some more noise made about those, please.

      What does it matter?

      Whether you believe it is happening or not? Whether I believe it is happening or not? The word belief keeps coming up time and again as it were a religion.

      What matters is whether it IS happening, not who believes it. If enough people believe in it, it won't start to happen if it wasn't before. I'm not having a go, I just find it curious.

      I wonder what the people who argued in the middle ages about whether the earth was round and whether it went round the sun would make of our discussions on climate change if they could be here today. There are similarities - the irrational belief (on both sides) of those who ought to know, the legions of people who can't know but who swing their allegiance between one side or the other based on who they like the most or will give them the lowest tax bill or biggest incentive, the vested interests (on both sides)

    Both sides are right here

    Rainforests in general should flourish all right. That is from the realm of the bleeding obvious. Co2, heat, water, what else can a tropical plant dream of.

    However nobody said that they will be the where the rainforests are now and nobody said that the humanity will allow them to grow where they would have naturally grown in the absence of Homo Sapiens and its industrialised civilisation.

    So if there will be a real disaster from global warming it will not be because of it per-se, but because of Humans fighting desperately for the Earth to stay the same instead of looking for a way to adapt to the new environment. It is the law of nature that species which refuse to adapt to a change in their environment go extinct. Some food for thought here...

      "It is the law of nature that species which refuse to adapt to a change in their environment go extinct."

      Interesting choice of words.

      When you say refuse to adapt, are you talking about the plants that refuse to get up and move when the valley they are living in gets too hot? Or are you talking about the penguins and walruses (I'll leave the polar bears alone today) refusing to move into the nearest commercial freezer when the poles become temperate?

      Changes in environment occur over a long time period (well, long for you and I, actually quite short in terms of geological timescale), certainly long enough for animals to breed, mutate and the mutants survive to breed and further mutate, adapting the species to survive in the new environment (this, of course, occurring over many generations).

      The problem with GW is that this change now appears to be occurring very rapidly and maybe too rapidly for many species to have the multiple generations needed to potentially survive the change. This has nothing to do with people trying desperately to stop the earth from changing. It has everything to do with recognising that change is occurring, identifying where human industrial activity is speeding up the process and trying to prevent those activities from speeding up the process too much.

    there's fast warming and slow warming; a fast transition to a higher temperature may well cause enormous disruption to human and ecological systems before this bright green rainforest future a few millennia hence, when the ecosystems have adapted.

    1. Robert Brockway

      Oh they're fighting all right

      The best hypothesis I've heard is this:

      Trees like CO2 levels higher than grass does. The trees and grass have been in a war for millions of years, each side trying to alter the environment to their preferred cO2 level. The trees have recently deployed their ultimate weapon (humans) to drive up the CO2 levels and defeat the evil grass once and for all.

    Adapting to the environment...

    Ummm - this is news ?.. The proliferation of new flora variants and adaptation of existing ones to higher levels of temperature and CO2 is a given, has been for.... umm pretty much as long as I can remember - and I wasn't aware that it was being disputed now by anyone - regardless of their stance on anthropogenic climate change.

    It also only a small part of the debate about possible global changes - some beneficial to some areas, some not.

    Interesting, for sure, but what was the point that i've missed ?

    All that CO2 is good for plants

    That would be the Paleocene era wich started with the extinction off the dinosaurs. All that CO2 may be good for our plants, but that doesn't mean it's healthy for larger vertebrates. Not a threat to "life on earth" then.. but probably not good news for us humans either.

  17. Kit Temple


    Well - seems pretty obvious to me. I didn't realise that really was a key concern of anyone. I thought it was more about the massive flooding, hurricanes etc. that will cause untold death and destruction.

    There are other aspects that become a little 'out of control' as temperatures rise. One is the massive permanently frozen methane fields in Russia - and methane as we know has a much worse effect on global warming than CO2. Also, wasn't there some issue with plant life in the Ocean suffering? Not sure the rainforests were ever seen as a key issue.

    I can't believe that many people would be surprised that tropical plants would be happy in a greenhouse.

    On the other hand chopping them down and growing cows in their place has been flagged as something we might want to avoid.

  22. Flocke Kroes Silver badge

    Old news backwards

    Increased temperature alone was not expected to kill rain forests. It would increase the activity of fungi and parasites so that trees would spend more energy on there immune systems, and less converting carbon dioxide into oxygen. The effect of increasing CO2 is not obvious, and years ago it was sensible to decrease emissions as a precaution because the potential costs could be enormous.

    Somehow, words like 'precaution', 'potential' and 'could' have mysteriously been replaced by 'necessary', 'certain' and 'will', without clearly published data to back them up. I am all for reducing our dependence on oil and gas independent of whether global warming is real or not. Unfortunately the current fashion is to build an impractical amount of over priced wind turbines - which will not be an effective way to substantially decrease dependence on oil and gas or reduce CO2.

    Is this not just common sense?

    Trees "inhale" CO2 and "exhale" O2 throughout the day ... and they thrive in warmer climates. If you want certain plants to grow well in our chillier northern climes you put them in a greenhouse...

    "Global warming" and higher CO2 levels would create a very plant-friendly environment I'd have thought. If the Discovery Channel hasn't lied to me then there was a LOT of CO2 in the atmosphere when plants first colonised the land and with little to eat them they spread like wild-fir (sorry) eventually absorbing enough CO2 and emitting enough Oxygen to chill the planet somewhat and raise O2 levels to a point much higher than they are today - leading to bloody big insects (dragonflies with 2m wingspan and the like).

    In fact, on a geological timescale, global warming is something of a non-issue. The planet has been much warmer in the past and it will (probably) be much warmer in the future. It's only us fragile meatbags that might suffer.

    1. copsewood

      Sure is common sense

      Increasing humidity, C02 and warmth for plant growth is common sense, so long as you don't mind having to evacuate coastal cities and plains where most people live. Next time you buy a house make sure it's at least 100 meters above sea level and nowhere near to a big river. And keep a few AK47s, machine guns and grenades at hand to fight off the climate change refugees who will want what you've got when most of the cities flood.

    A sample of 1 is not statistically reliable

    Remember science is based on the evidence of a body of research. One paper does not mean universal truth. However, there is a definite trend in published research which says that the cataclysmic predictions of earlier researchers were overstating the case.

    This is one more block in that body of evidence.


    But not a final answer all on its own.

    So while I welcome reporting on the continual research into climate change I hope we aren't falling into the tabloid trap of thinking that one published report changes everything.

    It will not be MILK chocolate.

    For that you need milk.

    So the rain forests need to be limited so we can have fields for the cows, to get milk.

    Never mind global warming, never mind CO2, never mind the rain forests.

    Nature is all powerful

    As a species we have an inbuilt need to feel all powerful and imporant. The idea that something might be more powerful or stronger than us is not allowed. Therefore, when global warming came along (or call it by its more common name these days, climate change), it had to be our fault as we're all powerful. It couldn't possibly also be the planet simply changing, much like it has done countless times in the past. We've had ice ages and periods of significant warming over history, even quite recent history. The middle ages were relatively warm compared to today. But, no, it had to be us as we're all powerful. So, using the same logic, if it was to be fixed (does it actually need fixing?), we had to do it. Hence, the entire climate change religion. The idea that nature might actually be able to keep it in balance is silly as obviously we're more powerful than nature.....aren't we. So, if CO2 levels rise, rain forest etc. gets bigger and keeps it in check!!

    Spin is best when it's mostly truth and simply misses out a few inconvenient facts. The article is a great example of this.

    Yes, the planet has been hotter in the past. Yes, it has had more CO2. Yes, the jungles were lush, and yes, life will adapt. Everything in the article is true, the only thing missing is the amount of time it will take life to adapt to the new warmer conditions. It's millions of years.

    The problem is that evolution happens very s..l..o..w..l..y and the planet is warming far faster than nature can adapt. This is why the extinction rate is thousands of times higher than the background rate. The planet has *never* warmed up as fast as it is doing now.

How can something that doesn't yet exist be flourishing?

    Misleading headline

    Warmer temperatures might be good for rainforests, but the important bit is how long did it take for those temperatures to become established, and did rainfall patterns match those expected from the current warming?

    One thing we do know from pollen cores is that the Amazon has repeatedly dried out in the past and been replaced by savannah-like landscapes dominated by grasses. The climate models suggest the Amazon is going to become more dominated by a wet and dry season which would encourage the die-off of trees.

    Rainforrests not doing so well

    This is just a theory but in actual fact, the rain forrests are being cut down at a high rate to plant crops for "eco-diesel".

    Oh the irony that higher temperatures would be ok for the rain forrests, but some spanner throwing monkey means that they'll all be cut-down to "stop global warming". And then further irony that the Earth has been warming for many thousands of years before man burnt his first piece of wood or coal, and in fact is the reason that the galciers no longer meet at the equator!

    Just one tanker-sized problem with El Reg's post...

    As per the El Reg modus operandi when it comes to climatology, take a paper that seemingly backs their skewed, denialist view and blow it out of proportion. Perhaps they could do us all the courtesy of reading the paper again and reporting WHAT IT ACTUALLY SAYS IN FULL. Global warming alone is not at all good for the rainforests as plants do not grow on increased temperatures or CO2 alone. Plants also need water. The current modelling and actual evidence for the threat to the rainforests of today from AGW is that there isn't a concomitant rise in the amount of WATER in the areas, to go along with the CO2 and heat. In fact, it is the opposite. There is less humidity, less rainfall and less water available to the fauna. Consequently, increasing temperatures are not good for the rainforest this time around and cannot be good.

    Relevant bit of text from the article for the idiots writing for El Reg:

    "Greenhouse experiments have shown that high levels of CO2 together with high levels of soil moisture improve the performance of plants under high temperatures (25), and it is possible that higher Paleogene CO2 levels (26) contributed to their success. ***Higher precipitation amounts could have been as important as high CO2. Precipitation reconstruction from a nearby Late Paleocene site, Cerrejon, indicate high precipitation regimes: about 3.2 m of rain per year.***"

    That is diametrically opposed to what is happening today.

    1. copsewood

      Please quote your sources

      "That is diametrically opposed to what is happening today."

      Not so sure either of us have a very good _global_ understanding of precipitation trends. Over the last 20 years or so, following previous decades of desertification, the Sahel has been getting greener:

      The problem is dominant memories of those old enough to have seen the very many news reports prior to this greening of the advancing desertification there. But the subsequent greening of the Sahel hasn't been reported in the same way at all, just one or 2 academic papers such as the one above based upon satellite imagery, and a few field observations I've seen which substantiate the above paper, which have received virtually zero media coverage.

    2. The Other Steve


      "There is less humidity, less rainfall and less water available to the fauna."

      And yet, that is not at all what yet another bit of research being widely screamed about by the chicken-littlers shows, suggesting that in fact the concomitant rise in humidity (hint: water evaporates more in the hot) will surely be what kills us all as parts of the planet become uninhabitable - because humans don't shift heat efficiently in high humidity* and eventually they die from heat stress.

      And yet people keep talking about this shit as though all the data, models, theories and predictions broadly agree.

    Ummm, no. You've got cause and effect all screwed up. The loss of rainforests is one of the causes, not effects, of GW (reduction of vegetation reduces carbon absorbed, etc.) The cause of rainforest loss is not GW, but massive active deforestation efforts.

    Sure, thriving rainforests could help mitigate GW, but 1) they take time to grow, and 2) we as a species appear to have this irrational aversion to land that is not flat and, ideally, paved.

    The worst thing about all this global warming lark.

    Is the fact that it completly overides the other consideration we should be having.

    Forest getting more CO2 and temp thrive yeah so what thought that was reasonably obvious in fact have a chat with people who grow planted fish tanks they have been adding CO2 to their tanks for years to boost rates.

    The problem is though everyone is so busy arguing about wether the climate change is happening or wether it is caused by us, that its overiding the fact that it would be nice to ave some environment left to worry about its said effects on.

    There does seem to be proof that the earth has gone through global warming and cooling periods before and that organisms have survived, but I would also guess that a lot of the same organisms died luckily at the time they probably had large enough populations to act as buffer zones to take the losses, the biggest problem we face is that we are constantly encroanching upon thise buffer zones.

    Course a lot of this is getting ignored as we argue over wether having more cows/ 4WD is a cause of climate change or not, personally for me thats the biggest problem with climate change.

    Warm Earth is good

    1. We are at a natural peak of interglacial warmth ( means between major ice age coldest period )

    and have been for about 8000 years .. this cycle is about 120,000 years and has been repeating for about 2,000,000 years .. during this 8000 years , there have been several relatively minor fluctuations .. the one that we can document as warmer than now, was the medieval warming period ...

    2. We can not accurately measure CO2 levels from ice cores, because the best resolution is 300 years, and it takes 4000-6000 years to form solid ice cores, and to some degree or another, the atmosphere during those 4000-6000 years mixes with the snow / ice .. in other words, there could have been a spike of CO2 higher than today for 50 years, and you would not see it in the ice core, provided the CO2 level was lower, on average, over 300-6000 years

    3. Plants .. including trees, are carbon neutral .. virtually all the CO2 plants bind up, is released back into the atmosphere over time .. either because the plant burns, or is eaten by animals, bugs, fungus, bacteria ..etc in the decay process

    4. The CO2 is higher because the ocean water is warmer and cannot absorb as much CO2 .. but please note the warming is first, causing the rise in CO2, not visa versa .. please look up "Carbon Cycle of Earth"

    5. It cracks me up that the "consensus" says CO2 increase is 9%-23% of global warming, and that water vapor is 50%-70% of the warming effect .. first it's funny because the range is so wide .. meaning it's very inaccurate 9 and therefore poor science ), and secondly funny because relative humidity has gone up in the same linear fashion as CO2 since 1951, yet no one is calling for water vapor reduction, or claiming said water vapor is excess man made water vapor

    6. this is important .. the UN did a study covering 1990-2000 to see the effect of increased CO2 on biosphere .. and they comcluded that over those 10 years there was 7% MORE Biomass ..

    .. it may very well be that we have not had massive famine any where in the world for decades, because of the CO2 increase .. because it is plant food ..and warmer land equals more crop land overall .. the CO2 and warming over the last 150 years, has been almost all a positive thing .. you can come to no other conclusion ..

    more water vapor = more rain and snow .. more snow is what will cool things down and lead us into the next ice age ( we are due for it as well in the natural cycle ) .. yet the oceans take 100s of years to cool down, so the tropics will keep evaporating water vapor into the air even as snowpack and glaciers rebuild, covering what is now valuable crop land and making growing seasons shorter elsewhere ..

    cold is the greater enemy of man .. 3 days of below freezing nights kills most food crops, heat, by itself does not .. remember .. colder air holds less moisture, cooler oceans evaporate less water vapor ( and absorb more CO2 ) .. so you have less rain over the remaining open land for crops and rivers, and the plant life grow less robustly with the lower CO2 levels .. which, BTW, helps it tolerate less water ..

    Nature in balance :-o

    So there were plenty of plants that thrived on a planet 5 degrees hotter and wetter. No real surprise there. But most of the tropical plants that thrived in the Cretaceous are extinct, so we'd have to wait a few million years for the new jungles to evolve. Maybe some of the existing species would like a change, but you know what they say about hothouse flowers

    Time to remember that 60m years ago the day was somewhat shorter than it is now and there was less time for the high temperatures to bake off vegetation creating deserts. Now, high temperature do not necessarily mean high vegetation growth and development rates. It might well be too hot for too long. On the other hand we might see adaptation. Leathery leaves could be the in thing and ficus robusta plants might take over the world.
