Global heating is creating “far-reaching and worsening” crises in every part of the U.S., according to a draft of a major upcoming report by the National Climate Assessment. The report finds the United States has warmed 68% faster than Earth as a whole over the past half-century. A drastic and urgent reduction in greenhouse gas emissions is the only way to slow down the climate-driven disasters from drought, excessive heat and extreme weather events. The report also says the worsening climate catastrophe will drive more forced migration, create public health crises and increase morbidity and mortality, and further threaten biodiversity. The authors note that if the world can reach zero or net zero emissions, warming will stop, curbing some of the worst effects of climate change. The U.S. would need to reduce emissions by over 6% every year to meet the Biden administration’s goal of net zero by 2050.
