Human-Caused Warming Likely Led to Record Streak of Hot Years

Saturday, 12 Aug, 2017

Previous year was Earth's warmest on record, according to an worldwide climate report issued Thursday by the National Oceanic and Atmospheric Administration that documents other record-breaking global warming trends of 2016.

The New York Times was forced to issue a correction on Wednesday after a much-hyped report on the Trump administration supposedly attempting to hide a climate change report didn't live up to the expectations they claimed. It also links human-propelled climate change with a decrease in the number of cool nights across the United States since the 1960s and an increase in the number of warm days since the 1980s.

Researchers attribute the record heat to long-term global warming and El Nino.

The amount of carbon dioxide, one of the main greenhouse gases, in the atmosphere climbed to its highest level in 800,000 years, the report found.

Reports, such as the NOAA-supported one released Thursday in the Bulletin of the American Meteorological Society, are "hard to dodge", according to David Schnare, who worked for a short time at the Environmental Protection Agency under Trump and wants the administration to abandon any efforts to tackle climate change.

Sea-level rise is expected to be worse in the Northeast and along the Gulf of Mexico, in part because the land in those regions is naturally subsiding.

In the sensitive polar regions, sea ice in both the Arctic and Antarctic hit record lows.

The condition of the Earth in 2016 is already proof that climate change is not a hoax and, while extreme climate patterns are worrisome, they are not really unexpected anymore. "Whether it's extreme droughts, or extreme floods, or extreme heat waves, when it comes to climate change impacts ... a lot of the most impactful climate related events are extreme events".

"With climate change, this is the kind of thing we would expect to see".

A new federal report could challenge the Trump administration's dismissive stance on global warming, finding the planet was hotter a year ago than in well over a century of observation and witnessed more climate disruption than perhaps any point in modern history.

Global surface temperature was also the highest on record.

Walsh said, whatever fears scientists might have, he's seen no political interference in the report to date. If greenhouse-gas emissions remain high and few steps are undertaken to better manage water resources, chronic long-lasting shortages - or hydrological drought - are possible by 2100. Global temperatures have increased by about 1.6 degrees over the past 150 years, the study found, and thousands of studies have created "many lines of evidence" to conclude that human activity is primarily behind the changing climate.

In addition, the global average sea level rose to a new record high in 2016, and, according to the new report, was about 3.25 inches (82 mm) higher than that observed in 1993, when satellite record-keeping for sea level began. The increase in the surface temperature of land and ocean in 2016 ranged from 0.45 to 0.56 degrees Celsius.
