2018 fourth hottest year on record NASA

08 February 2019

(WASHINGTON D.C.)- previous year was the fourth warmest since 1880, according to independent analyses by the National Aeronautics and Space Administration (NASA) and the National Oceanic Atmospheric Administration (NOAA).

The global temperature in 2018 was the fourth-hottest on record, scientists announced Wednesday.

The National Oceanic and Atmospheric Administration (NOAA) and The National Aeronautics and Space Administration (NASA) each published global climate results that name 2018 as the fourth warmest year the Earth has endured in at least 139 years.

"The five warmest years have, in fact, been the last five years", Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, tells the Times.

Since record keeping began in the 1880s, the average global surface temperature has risen around 2 degrees Fahrenheit (1 degree Celsius).

This year has also started with scorching temperatures, with destructive bushfires ravaging Tasmania as they endure their driest January ever.

"The 20 warmest years on record have been in the past 22 years". "The reduction of greenhouse gases and climate change adaptation measures around the world must be a priority", he said.

NASA and NOAA climate scientists said even though 2018 was a tad cooler than the three previous years that was mostly due to random weather variations.

"Single years count less than the Trend, and shows up", said Taalas.

Using computer simulations, the British weather office forecast that the next five years would average somewhere between 14.73°C to 15.27°C.

"The degree of warming during the past four years has been exceptional, both on land and in the ocean".

Many locations around the planet endured extreme weather and climate events in 2018, but the United States was hit particularly hard.

"That is not saying the Paris Agreement is done for. but it's a worrying sign", he added.

NOAA scientists used much of the same raw temperature data, but with a different baseline period and different interpolation into the Earth's polar and other data poor regions. Overall, 18 of the 19 warmest years have occurred since 2001. "That means kids graduating from high school have only known a world of record-breaking temperatures".

The records also show that the annual temperature of the Old Continent increased at an average rate of 0.12 Celsius degrees per decade since 1910, although it has nearly quadrupled to 0.43 Celsius since 1981.

Warming trends are strongest in the Arctic region, where 2018 saw the continued loss of sea ice.
