2018 temperatures set to be among hottest on record: UN

2018, fourth hottest year on record?
Average global temperature for Jan-Oct 2018 compared to that of the period 1850-1900 ("pre-industrial baseline")

Global temperatures in 2018 are set to be the fourth highest on record, the UN said Thursday, stressing the urgent need for action to rein in runaway warming of the planet.

In a report released ahead of the COP 24 in Poland, the World Meteorological Organization pointed out that the 20 warmest years on record have been in the past 22 years, and that "2018 is on course to be the 4th on record."

"This would mean that the past four years – 2015, 2016, 2017 and 2018 – are also the four warmest years in the series," the UN agency said in its provisional report on the state of the climate this year.

The "warming trend is obvious and continuing," WMO chief Petteri Taalas told reporters in Geneva.

The report shows that the global average temperature for the first 10 months of the year was nearly 1.0-degree Celsius above the pre-industrial era (1850-1900).

'Last generation'

"It is worth repeating once again that we are the first generation to fully understand and the last generation to be able to do something about it," Taalas warned.

With levels of greenhouse gases in the atmosphere, the main driver of climate change, at a record high, "we may see temperature increase of 3-5C by the end of the century," Taalas said.

"If we exploit all known fossil fuel resources, the temperature rise will be considerably higher."

Delegations from nearly 200 countries are due in Poland next week for the latest COP24 climate summit, aimed at renewing and building on the Paris deal and limiting .

World leaders have been trying to breathe new life into the 195-nation agreement amid backsliding from several nations—most notably the United States—over commitments made when it was signed in December 2015.

It is to take effect in 2020 and calls for limiting global warming to less than 1.5C above pre-industrial levels.

But experts warn that global warming is on track to surpass three degrees by 2100 and urge governments to do more than first planned to rein it in.

"Every fraction of a degree of warming makes a difference to and access to food and , to the extinction of animals and plants, to the survival of coral reefs and marine life," WMO deputy chief Elena Manaenkova stressed in a statement.

"It makes a difference to economic productivity, food security, and to the resilience of our infrastructure and cities," she said.

"It makes a difference to the speed of glacier melt and water supplies, and the future of low-lying islands and coastal communities."

tl;dr: 2018 was cooler than 2017, which was cooler than 2016 and 2015.

Great. Looking forward to seeing what 2019 will be like.

tl;dr:

Maybe you should read. It's worth a try.
It might help you get to the next stage (which is: understand),
...which in turn might help you get to the next stage (which is: think)

Right now you're just wasting oxygen and bandwith.

Huh? Given all the FUD in this article it's probably hard for people (like you, antialias_physorg) to get to the actual facts, so I summed them. The warmest years until now were 2015-2017 (of which 2017 was cooler than the others). 2018 is set to become the fourth warmest year, which means it will be cooler than 2015-2017. What's wrong with my tl;dr then?

The facts are indeed clear.
No matter what the avg for 2019 will be, Co2 continues to go up and temperatures will continue to rise long after it stabilizes, irrespective of multi-year fluctuations.
What was your point?

Nov 29, 2018
My point was that I prefer to read my facts straight, rather than warped beyond recognition into something that's supposed to make them more worrying. I'm not arguing about CO2 levels or long range trends. I just dislike being told the "warming trend is obvious and continuing," while at the same time being told (obliquely) that 2018 is cooler than previous years.

People are obviously afraid of giving facts straight, because they're worried that it will hurt their narrative. That, to me, is an insult to readers. I think that an article should present the facts straight and then, if the writer wants, present a narrative as other simple facts (like detailed long term stats).

and that "2018 is on course to be the 4th warmest year on record."

"This would mean that the past four years – 2015, 2016, 2017 and 2018 – are also the four warmest years in the series," the UN agency said in its provisional report on the state of the climate this year."

Antialias is right, you can't read. Or, possibly, you choose not to, just to be a troll.

If 2018 is cooler than some previous years, that will have no affect on the fact that "warming trend is obvious and continuing." That someone might suggest that it does indicates, to me at least, that just "giving facts straight" will allow some people to mislead themselves or others about what's happening. So, from your comment, you seem to be indicating that just "giving facts straight" is the wrong thing for scientists to be doing.

Nov 29, 2018
Comments here just emphasise the problem with scientific thinking with the public at large, and on a science site, too.

A good article would be like this: The expected temperature in 2018 is X. (Commentary) That's the 4th highest temperature ever. Temperatures over the last 20 years were (graph / table). (Commentary) There's a clear trend of rising temperature, and the decrease over the past 2 years doesn't indicate a long term improvement. The decrease in 2017 can be attributed to the lack of El-Nino, being the hottest such year without an El-Nino event. Global yearly temperature is calculated as such: ...

Such an article would have 100 times the information in the current article, with fewer words.

Nov 29, 2018
I thought the first sentence was pretty clear and succinct, "Global temperatures in 2018 are set to be the fourth highest on record, the UN said Thursday, stressing the urgent need for action to rein in runaway warming of the planet."

Nov 29, 2018
I know from observational record that the global temperatures have risen. If global temperatures of 2018 are nth lowest in 100 years, what is the value of n?

Nov 29, 2018
What more needs to be said than "the fourth hottest in the last four years, which are the four hottest on record?" I'm not sure what all the kerfuffle is about.

An El Nino in the ENSO is predicted for 2019, in which it will almost certainly make it the hottest year on record. Certainly in the Eastern Pacific.

Nov 29, 2018
well that was predictable , i did predict it , heres another one, 2019 was the hottest ever ! 2020 was the hottest ever !

interesting history ;;;;https://www.armst...he-most/


Nov 29, 2018
Hottest ever in Human history! CO2 levels are also there highest. It's time for the denier goons to worry.

A message to the failed American president Donald Drumpf from an American high school student Astha Sarmah

I am 54 years younger than you. I just finished high school with average marks. But even I can tell you that WEATHER IS NOT CLIMATE. If you want help understanding that, I can lend you my encyclopedia from when I was in 2nd grade. It has pictures and everything.

The heat waves to look foreward to
This summer, whatever the met office says
It has never constantly, day after day stayed at 40 degrees centigrade, that all the grass verges went white
And now, the end of November, the summer flowers are making one final last effort before December
May be next year will be a record hot year reaching 50 degrees centigrade
Now that would be an English summer heat wave to remember
Even in the desert of East Anglia

ET3D, despite your protests it is far more likely that you are simply a shit eater, who is addicted to fecal regurgitation. Your breath gives you away. Your shit spewing is no longer soiling my life.

http://www.temperature.global/

It's already been pointed out how crappy that site is. It uses unadjusted data (and doesn't even make the basic adjustments required to make the data useful) which makes any temperature it comes up with useless. It is beyond idiotic to believe that combining temperatures taken at midnight with ones taken in the morning and with others taken in the afternoon is a reasonable thing to do, but that's what they did. The site also avoids presenting its model for averaging the temperatures over the whole world. It also conveniently doesn't include many of the places on earth the are warming the fastest. I'm sure that all this wasn't done to fool idiots into believing the earth is cooling. ;)

Basically, that's a site created by idiots for the use of other idiots.

@zz5555, it makes one wonder how they manipulate the data when they're comparing temperatures at midnight in February in Jakarta with temperatures at noon in June in Warsaw.

''basic adjustments required to make the data useful ''

to whom i wonder ? LOL

''beyond idiotic to believe that combining temperatures taken at midnight with ones taken in the morning and with others taken in the afternoon is a reasonable thing to do, but ''''

but its still an average temp , of the earth .

''they manipulate the data ''

maybe they do , who knows ? you guys even admit to doing so yourselves
