Wunderground's Climate Change Position
Based on the evidence, more than 97% of climate scientists have concluded that human-caused climate change is happening. 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.
