According to a government report, unchecked climate change will cost the US hundreds of billions of dollars and damage human health and quality of life.
The 4th National Climate Assessment says: “Future risks from climate change depend… on decisions made today.”
The NCA 2018 report says climate change is “presenting growing challenges to human health and safety, quality of life, and the rate of economic growth”.
The warning is at odds with the Trump administration’s fossil fuels agenda.
The world’s leading scientists agree that climate change is human-induced and warn that natural fluctuations in temperature are being exacerbated by human activity.
The report – compiled with help from numerous US government agencies and departments – outlines the prospective impacts of climate change across every sector of American society.
The assessment says: “With continued growth in emissions at historic rates, annual losses in some economic sectors are projected to reach hundreds of billions of dollars by the end of the century – more than the current gross domestic product (GDP) of many US states.”
It also notes that the effects of climate change are already being felt in communities across the country, including more frequent and intense extreme weather and climate-related events.
However, the report says that projections of future catastrophe could change if society works to reduce greenhouse gas emissions and “to adapt to the changes that will occur”.
Last month, President Donald Trump accused climate change scientists of having a “political agenda”, telling Fox News he was unconvinced that humans were responsible for the earth’s rising temperatures.
After taking office, President Trump announced the US would withdraw from the Paris climate change agreement, which commits another 187 other countries to keeping rising global temperatures “well below” 2C above pre-industrial levels.
At the time, President Trump said he wanted to negotiate a new “fair” deal that would not disadvantage US businesses and workers.
