Global warming is certainly not a myth. In fact, it is upon us, according to the newly-released National Climate Assessment (NCA).
The grim report, compiled by a team of more than 300 experts guided by a 60-member Federal Advisory Committee, summarized the current impacts and projected effects of climate change in the United States.
“I think this National Climate Assessment is the loudest and clearest alarm bell to date, signaling the need to take urgent action to combat the threats to Americans from climate change,” said the White House science advisor John Holdren.
The report compiles the most compelling peer-reviewed scientific publications in the past several years. It delineates the effects of climate change on eight regions in the US.
According to the report, the average temperature in America has increased by about 1.5F (0.8C) since 1895, with more than 80% of that rise since 1980. Moreover, temperatures are projected to rise another 2F over the next few decades.
The effects of these temperature increases will be drastic.
The last decade has been the hottest on record in the US. If the record-breaking heat wave continues, it will increase the possibility of frequent droughts and larger wildfires in the South-west.
In the North-east, Midwest and Great Plains states, there will be an increase in heavy rains and more flooding. This has already begun as, according to the report, a 70% increase in heavy rainfall was recorded over the last 60 years in the North-eastern regions.
It is time for substantial action on the reduction of carbon emissions as the effects of climate change can now be seen in America’s own backyard.
