Study: 97% Agreement on Manmade Global Warming

The scientific agreement that climate change is happening, and that it's caused by human activity, is significant and growing, according to a new study published Thursday. The research, which is the most comprehensive analysis of climate research to date, found that 97.1% of the studies published between 1991 to 2011 that expressed a position on manmade climate change agreed that it was happening, and that it was due to human activity.

How Much Does It Cost: What Can I Do? (6)

My original list topper on diet was eat less meat. If we take the high emissions scenario as correct, then a climate priority calls for an intervention into our dietary practices that is comparable to the intervention required for reducing fossil fuels. This is a change in diet that I assert will be more difficult than the change in our energy system. Therefore, back to the original question, “What can I do about climate change?” – eat (a lot) less meat. Vegetarianism is good for the planet.
Wunderground's Climate Change Position
Earth's climate is warming. This time, humans are mostly responsible, and the overwhelming majority of climate scientists agree. Climate change is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. We can choose to take economically sensible steps to lessen the damage of climate change, and the cost of inaction is much higher than the cost of action.
