More than 200 climate scientists just released a stark look at how fast the climate is warming, showing heat waves, extreme rain and intense droughts are on the rise. The evidence for warming is "unequivocal" but the extent of future disasters will be determined by how fast governments can cut heat-trapping emissions. Here are the top findings from the report.
1) Humans are causing rapid and widespread warming
Carbon dioxide in the atmosphere has now reached the highest level in at least the past 2 million years. As a result, temperatures are warming quickly. Since 1970, global temperatures have increased faster than in any other 50-year period in the last 2,000 years. Some parts of the globe, like the poles, are warming even faster.
2) Extreme weather is on the rise and will keep getting worse
Heat waves are more frequent and intense. Storms are dumping more rainfall, causing floods. Droughts are getting hotter and drier. Scientists are finding these trends are directly linked to the human influence on the climate and they're getting worse.
3) If humans cut emissions, the worst impacts are avoidable
While the planet will continue to warm in the near term, scientists say there is still time to prevent catastrophic climate change. That would mean a rapid drop in emissions from power plants and cars over the next few decades, essentially halting the use of fossil fuels.
