The report by investigators from the NOAA Environmental National Information Centers and with the contrbution of more than 450 scientists from nearly 60 U.S. states, pointed out that most of the climatic change warning signs followed the clues of a warming planet.
Not only is warming speeding up, but it is happening even faster up North. Since 2000, the maritime temperature is increasing by 2.92 degrees Fahrenheit per century, much more than the 1950-2016 trend of warming at 1.8 degrees per century.
A statement from NOAA says: "NOAA's updated 2017 Atlantic Hurricane Season Outlook indicates that an above-normal hurricane season is most likely, with the possibility that the season could be extremely active". There were more significant tropical cyclones than any year, droughts that lasted longer, and fewer snowfalls. Heavy rainfall events have become more frequent and more intense since 1901 in most parts of the US, and that's particularly true for the Northeastern US.
Global surface temperature was also the highest on record.
There is more extreme heat. The amount of precipitation that falls in the heaviest storms is higher across the country, when storms from the last three decades are compared to storms from 1900 to 1960.
There's more extreme rain. By the end of the century, for example, parts of Charleston, South Carolina, may flood at high tide almost every day. Federal policies that determine the use of Federal Emergency Management funding and the laws that are set regarding industries with high carbon emissions will no doubt be affect by the position the Trump administration takes regarding climate change.
The National Oceanic and Atmospheric Administration (NOAA), a leading environmental agency which is part of the United States federal government, found that global temperatures were warmer last year than in 137 years of recordkeeping for a third consecutive year - surpassing the previosu record of 2015.
The rate of warming in the Arctic, which is happening at twice the rate of the rest of the globe, has major impacts on local ecosystems, but also further drives the warming of the planet, as the sea ice that would reflect the sun's rays back to space is lost. "For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence".
Greenhouse gas concentrations were up.
"For example: Increases in the intensity and frequency of extreme heat including deadly heat waves such as the ones that killed about 40,000 Europeans in 2003 and devastated parts of Russian Federation in 2010 have been convincingly linked to climate change", Oppenheimer added. In the case of climate scientists, the reason for calling greater public attention to a compilation of climate-science studies was to prevent suppression or heavy editing from the Trump administration's horde of climate-change deniers.
