Human-accelerated climate change is real. We can make it much worse. And the sooner we tackle it, the cheaper it will be.
That's the tl;dr version of a report released today by the AAAS Climate Science Panel. The AAAS (American Association for the Advancement of Science) has previously released statements on anthropogenic climate change, such as this one from 2006 and this one from 2009. You have heard of the AAAS even if you think you haven't; they're the organization that publishes Science, one of the two highest-prestige scientific publications of the past century.
The report, and accompanying website with videos, explain in as plain of language as possible what the scientific community knows about anthropogenic climate change, in three (hopefully) easy-to-digest soundbites.
- Reality: People who study climate are convinced, by large amounts of evidence, that anthropogenic climate change is occurring.
- Risk: Anthropogenic climate change is happening quicker than natural systems can counteract it, leading to unpredictable consequences.
- Response: Mitigating and adapting to ACC is cheaper if done sooner than later.
