Earth System Trend
UNIT: Degrees Celsius
Getting ill is no fun. Your temperature rises just a little but you feel terrible. Our planet is getting warmer. In the short term this means wet areas are likely to get wetter and dry areas drier. Extreme weather may hit some places. In the long term, rising temperatures will threaten vulnerable societies, crop production, coastal cities and even the existence of a global civilization. Our actions may push the climate – or parts of the system such as ice sheets, rainforests or ocean circulations – past thresholds, where the behavior becomes unstable.
