Study: Climate was hotter in Roman, medieval times than now

Re: ^^ What Phil said... but what matters more is ...

What you say is true, but you need to understand it isn't just that simple. Climate change doesn't only affect our way of life, it causes CLIMATE change globally. This means overall loss in biodiversity through habitat loss and habitat expansions. Polar bears will go extinct, most Arctic species will.

The warming, on a slow rate, can be adapted to. Species can evolve to additional heat, but not at the current rate we are warming things up... You also need to remember, there can be feedback loops we have to worry about. Yes, there may be some for cooling trends, but it seems as if the warming feedback loops are exceptionally stronger. Methane release from permafrost would rapidly accelerate warming trends. Loss of global albedo as a result of milder winters, and reduced Arctic sea ice, would accelerate warming trends.

It isn't just the warming you need to consider. Remember that thermal expansion can affect the water levels greater than the uprise of continents due to loss of glaciers. The glaciers currently don't impact the continents level to the amount continental glaciers do.

With the CO2 increase there is also acidification of oceans, which is something to worry about. Even a pH change of 1could kill most life in the ocean. The oceans absorb the majority of CO2 in the atmosphere, but that causes carbonic acid production, and then acidification. Worrying about warming is something to worry about. Venus has been suggested to look similar to earth a few billion years ago... That is climate change run amuc

Re: Solar Activity

Seriously the solar activity thing? Scientists have always taken solar activity into account. Sunspots (running on 11 year cycles) They also take into account the cycles of the earths rotation, precession, as well as axial tilt cumulating in a 90000 year cycle which we UNDERSTAND and have for hundreds of years. Solar activity is typically fairly constant. Sunspots don't follow the trend anymore. Besides, haven't you ever noticed by all climate graphs in opposition to climate change seem to STOP before 1900...

Seriously still?

"and a long-term cooling trend (dashed red curve; linear regression fit to the reconstruction over the 138 BC–AD 1900 period)."

Did any of you even seem to figure out that the trend line stops once we get the most up to date data?? Can you ever wonder why that is.... Also, this graph also shows the highest temperatures are still in the newest part of the century. The trend line does not follow past 1900, because that is where the trend ENDS. The data also shows that the highest temperature was not during the Roman times, but now (figure 2.b in the paper).

The graph showed an overall cooling trend which we are now, no longer following. The climate does work in cycles, but we put a big middle finger up and said, not any more.
