Last year was fourth warmest as greenhouse gases rise

2018 lags only 2016, 2017 and 2015 in record heat.

Last year was the fourth warmest on record, extending a scorching streak driven by a build-up of man-made greenhouse gases, the European Union’s Copernicus Climate Change Service said on Monday.

Average world surface air temperatures were 14.7 Celsius (58.5 Fahrenheit) in 2018, just 0.2C off the highest, it said in the first global assessment based on full-year data. This year will also likely be hot, its scientists said.

“Dramatic climatic events like the warm and dry summer in large parts of Europe or the increasing temperature around the Arctic regions are alarming signs to all of us,” said Jean-Noël Thépaut, head of Copernicus.

Among other extremes in 2018, California and Greece suffered severe wildfires, Kerala in India had the worst flooding since the 1920s and heatwaves struck from Australia to North Africa.

Around Antarctica, the extent of sea ice is at a record low at the start of 2019, according to the US National Snow and Ice Data Center.

Copernicus chief scientist Freja Vamborg said 2019 would also likely be hot. “We now have a nascent El Nino – it depends partly on what happens … will it continue or die out?” she told Reuters.

Paris accord

The last four years have seen the highest average temperatures since records began in the 19th century – 2016 was the hottest, boosted by an El Nino event that warmed the surface of the Pacific Ocean, ahead of 2017 and then 2015.

The Copernicus report said that concentrations of heat-trapping carbon dioxide in the atmosphere rose to a new record of 406.7 parts per million (ppm) in 2018 from 404.1 in 2017, stoked largely by human burning of fossil fuels.

And the average global temperature in the past five years was 1.1C (2.0F) above pre-industrial times, it said.

According to a UN climate report last year, temperatures will rise 1.5C above pre-industrial times by mid-century on current trends – bringing the prospect of even more extreme weather.

That UN report said governments would have to make unprecedented cuts in greenhouse gases to keep temperatures below the 1.5C rise, which is the toughest goal set in the 2015 Paris Agreement.

Almost 200 nations agreed a “rule book” to govern the Paris accord in talks in Poland last month, even though critics said it was insufficient to prevent dangerous climate change.

The Paris accord seeks to end the fossil fuel era this century by shifting to cleaner energies such as wind and solar power. US President Donald Trump plans to pull out and instead promote the US fossil fuel industry.

The Copernicus report confirms projections by the UN’s World Meteorological Organization (WMO) in November that 2018 would be fourth warmest.

The WMO will issue its own estimate for 2018 temperatures in coming weeks, also comprising data compiled by US, British and Japanese agencies.

This article again blames Trump for not signing the Paris accord. The reality is that the agreement should have been signed by Obama, but there was no way that he could persuade the Congress to ratify it despite the Democratic majority, so he shelved it quietly. But of course criticising Obama by the left is not allowed. Trump simply dropped the whole thing and as usual he is blamed for it.
As an engineer who designed several measuring instruments over the years I know how hard even today to measure temperature with 0.1C accuracy I simply can not accept that 100 years ago the measurements were more accurate than 1 degree. BTW, just because a thermometer shows readings to tenth of a degree it can be several degrees off. Resolution and accuracy has no connection.

So you’re shooting down the whole article on a footnote? A single sentence about a man far far away, who, like the man a little bit closer, makes decisions that prove he doesn’t care about majority opinion?

And denying warming because other engineers are inventing far better air-conditioning? Maybe take a walk outside. Skin is a pretty good measuring instrument.

No, I have problem with accepting the 50-100 years old temperature measurements as gospel. If 100 years ago the temperatures recorded were not accurate to better than 1 degree, how can you claim that currently the temperatures are 1 degree higher?

Why do you bring up air-conditioning? The article does not mention it and it has nothing to do with temperature records and measurements.
Going outside does not indicate anything. I can not find old historical temperatures for SA, but Hungary, my country of birth has plenty going back to more than 100 years. Looking at those the maximum ever recorded on this day (12th January) was +16 degrees in 1977, the lowest -31.9 in 2003. If I would look ONLY on this I could say that the temperatures are dropping, which is stupid. There are plenty examples from all over the world where the highest temperature on record happened long ago, for example returning to Hungary, the highest temperature on record on 18th of January is +16 degrees recorded in 1918, exactly 100 years ago. As they say, weather (going outside) is different from climate.

Exactly 1 degree worldwide, I won’t claim. Much hotter, here is what I’m saying.

THE CLIMATE CHANGE HOAX!

Look up on Youtube: Mark Steyn’s libel lawsuit

The Paris “accord” was nothing but a wish list of what they all “said” They would “try” to achieve. By the way the computer modelling for climate change was all manufactured by INPUT DATA that was flawed. There is NO EMPIRICAL EVIDENCE OF THIS.

Referring to the last paragraph “…comprising data from US and other agencies..” , here’s a handy website address one can always check what the next season’s climate forecast may be like…be it El Nino or La Nina.

Have been following it since mid 2018…already there was a 70-80% chance of (moderate) El Nino for SA over the current 2018/19 summer rainfall regions. Indicating drier conditions. Last year I read some SA weather experts comment they hope for a wet summer rainfall reason back then, despite known data available from this NOAA-site.
It’s now been slightly reduced to a 65% probability….so we may be experiencing a mild El Nino in SA (i.e. drier conditions). It is felt on ground level?…I certainly think so…
