The effects of climate change pose risks not only to the earth's natural ecosystems but also to the security and livelihood of the people of the United States and around the world. In its 2018 special report, the Intergovernmental Panel on Climate Change (IPCC) suggests that the speed and scale of the consequences of global warming have intensified faster than projected. The IPCC concludes that in some parts of the globe, at certain times of year, temperatures have already risen 1.5 degrees Celsius above preindustrial levels, increasing the probability of severe weather and other conditions expected from a warming planet. Still, specific challenges vary by location and intensity, even within national geographies such as the United States. Thus discussion that focuses on global average measurements and consequences will miss the mark.
