Climate scientist Radley Horton, one of the lead authors of the National Climate Assessment report released this week, will answer your questions in an “Ask Me Anything” session on Reddit on Friday starting at 11 a.m.
In a story posted on the Earth Institute site earlier this week, Horton summed up the report this way: “The overall message is that climate change is happening right now—we can’t think of this as an issue for future generations.” Horton works at the institute’s Center for Climate Systems Research, and the affiliated NASA Goddard Institute for Space Studies. He was convening lead author for the assessment’s Northeast chapter.
The impacts of a changing climate include rising sea levels that contribute to coastal flooding, more extreme precipitation events, more extensive heat waves and drought, increased acidity in the oceans that can threaten sea life, and on land, shifts in the ranges of plants and animals.
For a useful summary of the assessment, the White House has published a fact sheet on “What Climate Change Means for Regions across America and Major Sectors of the Economy.”
More and more, scientists are speaking out about climate, in part because much of the public and policymakers express skepticism about the science. There are many reasons why so many people believe that the whole notion of climate change being caused by human activity is still up for debate. But it’s not, at least among most scientists who study the issue.
The issue is daunting, so global that it’s tough for people to grasp what exactly they can do about it. Reducing greenhouse gas emissions and adapting to a new climate future will take major shifts in policy in many countries around the globe. But that doesn’t mean individuals have to stand still and wait: A State of the Planet story outlines some of the ways you can focus on the issue.
