Toronto's average temperature was 1.5°C warmer than normal in 2018

2018 was one of the hottest years on record — and this year could be even hotter 2018 Fourth Hottest Year On Record, Says NASA

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 United Kingdom Met Office, the U.K.'s weather service, said global temperatures over the next five years will average somewhere between 58.51 and 59.49 degrees Fahrenheit, or 14.73 to 15.27 Celsius.

The National Oceanic and Atmospheric Administration released a 2018 climate assessment Wednesday, and the temperatures continue to climb.

And according to their study, the past five years are, collectively, the warmest years in the modern record.

The average global surface temperature has risen above the 20th-century average by 0.79ºC.

"We're no longer talking about a situation where global warming is something in the future", said Gavin A. Schmidt, director of the Goddard Institute for Space Studies, the NASA group that conducted the analysis.

Nasa's data was compiled by 6,300 weather stations around the world and was compared against information stretching back to 1880. 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. Even though it is still highly likely those landmark temperatures will be surpassed in due time, the Paris accords were an global gesture of good faith to help protect our planet.

Much of Europe had its warmest years on record.

Macedonia's NATO Journey Not Over Yet, Experts Warn
Moscow had taken a dim view of the name accord, and of Macedonian membership in North Atlantic Treaty Organisation . A majority of 153 lawmakers supported the legislation, while 140 voted against.

Taalas said the extreme weather events of the past year have had "devastating repercussions" for people, economies and ecosystems.

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.

Global air temperatures have warmed steadily over past decades, shifting up and down slightly from year to year depending on natural climate oscillations like El Niño, but following a consistent upward path.

Weather dynamics often affect regional temperatures, so not every region experienced the same degree of warming. In the past 5 years, the annual average rose to 12.6.

I'd like to get more stories like this. Climate scientists say that the higher rainfall is largely due to warming oceans, which cause more evaporation that in turn leads to more rain.

The 2018 global temperature reports were originally scheduled for release in mid-January, but they were delayed because the 35-day partial government shutdown prevented government scientists from finalizing their calculations.

"The planet is warming".

The damage included Hurricane Michael's US$25 billion tally and US$24 billion each from Hurricane Florence and the western wildfires.
