4th Hottest Year On Record, Arctic Warming Faster

According to NOAA, 2018 was Arizona's second warmest year ever recorded, one of a dozen states with similarly high temperature averages. That means 2018 was the fourth hottest year recorded in over 100 years.

If Toronto felt warmer than usual a year ago, it's because it was.

NASA says the average global temperature has risen by about 1° C (2° F) since records began in 1880.

Due to the dynamic character of global weather patterns, not every place of the Earth experiences the same levels of warming.

Schmidt also stated he was "very concerned with what is going on in the Arctic" as it is heating up at twice the average rate of the rest of the world, and 2018 saw the average extent of sea ice at its lowest level. It is also linked the extremely cold temperatures the Midwest and Northeast experiences last week.

The Earth experienced its fourth-hottest year in more than 136 years in 2018.

NASA's data takes temperatures from 6,300 weather stations along with ship and buoy-based observations of sea surface temperatures along with measurements from Antarctic research stations.

An independent analysis released last month by Berkeley Earth calculated that in 2018, 85 percent of the Earth's surface was significantly warmer than the planet's average temperature from 1951 to 1980.

Record land temperatures occurred in parts of the Middle East, Europe and New Zealand. Deathly record lows are real in the U.S., but don't be fooled by the cooling that we have been witnessing, global warming is real also.

"Many of the extreme weather events are consistent with what we expect from a changing climate", he said.

It appears highly likely, at least from today's perspective, that that line will be crossed, despite the fact that more than 190 countries have signed the Paris climate agreement, which sets targets for reducing greenhouse gas emissions. This year has started with mild El Nino conditions, "which suggests 2019 will be warmer than 2018 but that's more a rule of thumb than a firm prediction", Schmidt said. NOAA's analysis found 2018 global temperatures were 1.42 degrees Fahrenheit (0.79 degrees Celsius) above the 20th century average.

That temperature was topped only in 2016, 2017, and 2015. The quickly rising temperatures over the past two decades cap a much longer warming trend documented by researchers and correspond with the scientific consensus that climate change is caused by human activity.
