2018 fourth warmest year in continued warming trend, according to NASA, NOAA

2018 fourth warmest year in continued warming trend, according to NASA, NOAA

Last year was the fourth-hottest year ever recorded, according to the National Oceanic and Atmospheric Administration and NASA, which means that the past five years have been the five warmest years in the modern record. The top three costliest natural disasters globally were all in the USA, making it their fourth-costliest year ever, at $160 billion. Collectively the four years are the warmest recorded since 1880.

"The impacts of long-term global warming are already being felt in coastal floodings, heat waves, intense precipitation and ecosystem change", said Schmidt. It founds that 2018 global temperatures were 0.79 degrees Celsius above the 20th-century average.

"Over the next five years there is a one in 10 chance of one of those years breaking the (1.5C) threshold", Professor Adam Scaife of the Met Office told Reuters of the agency's medium-term forecasts.

"The 20 warmest years on record have been in the past 22 years", Mr Taalas said.

The United Nations says the world is now on track for a temperature rise of 3C or more by 2100.

2018, it turns out, broke quite a few records, none of them good.




Weather dynamics mean warming affects regions in different ways.

The WMO said heightened temperatures also contributed to a number of extreme weather events such as hurricanes, droughts and flash flooding.

Earlier this month, Sputnik reported that Australia's current heatwave, with temperatures exceeding 30 degrees C in some areas, is expected to continue through April, according to the country's Bureau of Meteorology.

Given that we desperately want to avoid rising above that global average temperature to avoid climate catastrophe for millions - if not billions - of people, now is the time to take climate action seriously, and begin the rapid transition of the global economy over to a low-carbon one, that relies on green, renewable energy.

All the results show the same "escalator-like" rise that scientists think is linked to the loss of sea ice, as well as an increase in extreme weather events around the world.

NASA's temperature analyses came from 6,300 weather stations, ship and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.
