2018 was Earth's fourth-hottest year on record, NOAA and NASA report

NOAA's report showed that a long-term heating trend continued last year as persistent warmth across large swaths of land and ocean resulted in the fourth hottest year in NOAA's 139-year climate record.

The climate report is an annual summary of research compiled by scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA).

In Phoenix, 2018 was the seventh-warmest year on record, according to the National Weather Service.

The year 2018 was the Earth's fourth-hottest year on record, continuing a decades-long progression of warming, with the past five years collectively the warmest on record, according to reports released Wednesday.

"2018 is yet again an extremely warm year on top of a long-term global warming trend".

It was largely driven by increased emissions into the atmosphere of carbon dioxide and other greenhouse gases caused by human activities, according to Schmidt. Scientists have linked climate change to more destructive hurricanes like Michael and Florence previous year, and have found links to such phenomena as the polar vortex, which last week delivered bone-chilling blasts to the American Midwest and Northeast.

In addition to the temperature records, the US suffered $91 billion in direct losses from extreme weather events in 2018, the fourth most since 1980, Ardnt said. It was the fourth highest since 1880, the earliest year for which records are available.

"Eighteen of the nineteen warmest years since record keeping began have occurred since 2001". Such cold weather has made it really hard for many to believe that global warming is real.

NASA does point out that weather dynamics affect regional temperatures, so not every region on Earth saw similar amounts of warming. "The trend is going relentlessly up, and it will continue to do so", Potsdam Institute climate scientist Stefan Rahmstorf said in an e-mail. 2016, boosted by a strong El Nino that normally tips the mercury northwards, remains the hottest year on record.

Because weather station locations and measurement practices change over time, the interpretation of specific year-to-year global mean temperature differences has some uncertainties.

I'd like to get more stories like this. Instead, his administration is working to unravel Obama-era environmental rules in favor of policies that would allow more greenhouse gas emissions from cars, trucks and coal-fired power plants. That's 1.42 degrees (0.79 Celsius) warmer than the 20th century average.

Despite global efforts, planet-warming emissions are trending upward. Hurricanes Florence and Michael and wildfires in the West accounted for $73 billion of that loss.
