Climate change is something that we cannot fix alone - it is the original collective action problem - it will not work unless almost all the large economies of the world act together.
You can't solve climate change by everybody individually buying a more efficient car and throwing out less stuff. You have to make national changes through national policy.
We need to start by having a conversation about climate change. It would be irresponsible to avoid the issue just because it's uncomfortable to talk about.
As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions.
Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.
Human-caused climate change threatens almost every aspect of human existence.
I would much rather we concentrated on the immediate, still-potent dangers, such as nuclear weapons, runaway climate change, and so on. Sort those out, then worry about Hal 9000.
Climate change might be disastrous, but does that mean we want carbon taxes that raise the price of a gallon of heating oil to $10? And how exactly will those taxes affect economic growth?
The mammoth was basically done in by climate change. The last ones survived on Wrangel Island, north of Chukotka, until 3,700 years ago. According to Eveny mythology, mammoths scooped up dirt with their tusks to form the first dry land.
Make no mistake: Tackling climate change is vital. But to see everything through the lens of short-term CO2 reductions, letting our obsession with carbon blind us to the bigger picture, is to court catastrophe.
