Re: Surprising....how?
What's missing in your discussion is the rate of climate change now compared to previous climate changes. No scientist is claiming that we can 'reverse' climate change but we can take steps to bring it back to its natural rate of change.
The pivotal question in this discussion is: What has changed between the previous climate changes and the present? The answer is human population explosion and burning of fossil fuel. This has resulted in level of CO2, a greenhouse gas, far greater than Mother Nature can absorb and convert to more benign forms, i.e. in plants and rocks.
Your suggestion that we continue on our merry path is exactly what we must not do. We know the danger and the risk, and we know how to positively influence the solution. Why wouldn't we want to do other than for self interest of those that dislike the solutions simply because it negatively impact on their current business model, i.e. their profits.
We have not yet invented a way to bring back time. We can't go back to per-industrial era and try a different approach to generate energy. The time to act is now, and we already late! Debating if the impact of humans on current climate change is 1% or 20% or 100% is a futile debate. It's all about managing risks. We have sufficient evidence that human activities has an impact on the current rapid rate of climate change. What we should be discussing is: what are we going to do about it? The rest is just time wasting of gross and criminal proportion.
