2015, the hottest of years, and by far

The Monde.fr | 20.01.2016

The announcement was anticipated. She is now official. The 2015 year was - by far - the hottest in modern history. The US Oceanic and Atmospheric Agency (NOAA) and the US Space Agency (NASA), both of which keep track of the planet's temperature record, jointly confirmed it Wednesday, January 20.

The statements of the two agencies, drawn up independently, differ slightly. But they agree that average temperatures have been the highest since the start of 1880 measurements. According to the NOAA, they exceeded the average of the twentieth century by 0,9 ° C and surpassed by 0,16 ° C the previous peak reached in 2014. NASA reports an increase of 0,87 ° C compared to the average of the 1951-1980 period, 0,13 ° C above,

indicates the NOAA. The month of December itself broke all records, exceeding by 1,11 ° C the average of the past century. The 2015 year ranks well ahead of the hottest years, ahead of, in order, 2014, 2010, 2013, 2005, 2009 and 1998.

We are not the miser ... What will 2016 give?

I hold the bet that:

If TENDANCE BISS:
1) the situation will not improve even if the ultra who do not support the hypothesis of warming announce (conditional) a return to cooler temperatures of a phenomenon that has already begun (for them we would have reached the peak) ... And since in the state the influence of the man has repercussions that go rather upward trend until then ...

2) since they are mistaken about gravity, at best the situation will stay at these thresholds of mild winters for at least ten years ...

If TRENDY TREND:
1) the situation should get worse, off we are an El Niño year so we will have to wait for the 2016-2017, 2017-2018, 2019-2020 and 2020-2021 winters to see what the trend is! (and even then it will make a very small decline)

2) According to the "moderate" opponents of the uptrend and who do not refute it, Vincent Courtillot, professor of geophysics has shed some light here >>> that is relevant and which tends to demonstrate that there is no expected cataclysm. While stressing that human activity has an impact. Its opinion is interesting in that it refutes the dominant thesis with arguments themselves too scientific. And it also shows some flexibility that we thought impossible (finally will see ...)

But I prefer not to pronounce in my personal capacity these are only pure speculations ...

A THING IS SAFE, IT IS THAT ONE CAN NOT DENY THAT THERE IS ANY WELL WARRANTY (...)

Heat record this winter in France: almost 8 ° C on average

02 March 2016

The meteorological winter ended the 29 February and gave way to the meteorological spring the 1er March. The record is clear: the winter 2015-2016 is the hottest ever observed in France.

The meteorological winter ended on February 29. The results are clear: the 2015-2016 winter is the hottest observed in France since the first weather reports, according to "MeteoNews". Averaged over the network of stations installed after the Second World War, it indicates a national average temperature of 7,9 ° C.

Gentleness has been ubiquitous throughout this winter, especially in December (+ 3,7 ° C), extremely hot and off-normal, the hottest since the first weather records in France in the middle of 17e century.

A very mild winter ...

Although less extreme, January (+ 1,8 ° C) and February (+ 1,4 ° C) were very mild, maintaining the average of the season well above normal 1981-2010. In the end, with 7,9 national average temperature degrees, calculated on 170 metropolitan stations, winter 2015-2016 exceeds the normal of 2,3 degrees.

It beats the average 7,7 1989 / 1990 winter averages whose extreme softness was mostly due to a historically hot February, much sweeter than February 2016.

Can we link this extremely hot winter to global warming? "Yes, that's a fact. The increase in mild winters over the past 30 years fits perfectly into the context of global warming, which affects all seasons. Be careful, however, of the fall. The current warming will not prevent, in a more or less near future, to return to very cold climatic conditions in France and in Europe during the coming winters "specifies the forecaster Frédéric Decker.

... but also rainy and gray

According to the specialist, the month of February was also very rainy: "France received an average of 95 mm of precipitation during the month, an excess of 73%. The rains were mainly concentrated in the southwest of the country. As for the precipitation, the very important sunshine in December was filled by months of January and February darker than usual ". And the sun hid a bit: it shone only 269 hours on average over our country during these three winter months, and January and February suffered from an often abundant cloud cover, significantly reducing the hours of Sun.

February 2016 was the hottest February ever recorded

METEO These latest heat records illustrate the continued acceleration of global warming ...

17.03.2016 20minutes.fr AFP

The month of February was the second month of the hottest year in the world ever recorded since the start of 1880 temperature readings.

"The average surface temperature of land and oceans has reached 12,1 degrees Celsius, the highest for a month of February since 1880, exceeding by 1,2 ° C the average of the twentieth century," said Thursday the US Oceanic Agency and atmospheric (NOAA).


July 2015 remains champion all categories
This difference in 1,2 ° C means that last month was the strongest temperature anomaly compared to the average February since 1880. Meteorologists note that this is even the largest anomaly compared to the average of 1.646 months measured since 1880, exceeding the record 0,9 ° C change of December 2015.
July 2015 keeps its absolute record of the hottest month ever recorded on the planet, with an average temperature of 15,8 ° C.

Records over several consecutive months

NOAA also said that February 2016 was "the tenth consecutive month in which the world's weather beats a new record."
These latest heat records illustrate the continued acceleration of global warming. Mercury has, by far, broken a new record for the 2015 year, surpassing that of 2014, a phenomenon most climate scientists attribute to the accumulation in the atmosphere of greenhouse gases from combustion. oil and coal.

The unusually small ice extent

Since 1997, the first year since 1880 had a record-breaking thermometer surge on the planet, 16's 18 years have been warmer, according to NOAA.

........

The NOAA also said Thursday that ice extent in the Arctic Ocean was unusually low with an average area of ​​1,16 million square kilometers, which is 7,54% below the 1981 average at 2010.

I am surprised to see that the global average of July is almost 4 ° higher than that of February.
Yet when it's summer in the north, it's winter in the south. This is probably because there is more land in the north, which has less heat than the oceans?

[Christophe]

This is probably because there is more land in the north, which has less heat than the oceans?

Yes I think the same ... the oceans have a much larger heat capacity and are the thermal regulators of the planet!

A ladle, I would say that a good 65% of the land is in the northern hemisphere ...

Now when we talk about global average T ° there is only the method of analysis of the IR radiation by satellite which is valid in my opinion ... it is indeed difficult to make planetary global averages on a finite number of points measurement (but that can give an idea)

[Christophe]

A ladle, I would say that a good 65% of the land is in the northern hemisphere ...

I have a pretty good ladle lol: http://www.larousse.fr/encyclopedie/div ... 9es/186017
In fact it is almost 75% according to Larousse.

near to three quarters of them are north of the equatorso that the land area is about 40% of the area of ​​the Northern Hemisphere, for 19% that of the Southern Hemisphere. The first consequence of this distribution is the extreme variety and instability of physical phenomena in the Northern Hemisphere, compared with the magnitude and regularity of the corresponding phenomena in the Southern Hemisphere, dominated by oceanic influences.

On the other hand the ratio 40% / 19% says that there is therefore 2.1 times more land in the north than in the south... in the end it is a report (since the 2 hemispheres have ... a priori ... the same surface) of 67.7% (40 / 59) of emerged land for the north, so closer to my ladle as 75% ... rather 2 / 3 than 3 / 4 so?

This passage also confirms the role of regulator of the oceans: much more marked in the South than in the North.

The 1er paragraph is also interesting:

It is necessary to add to them the continental platforms, covered by shallow seaspaces, which adds 35 millions of km2 and 7% of the surface of the planet. In this extended sense, the continental masses thus cover 36% of the Earth.

So in fact, there is land submerged in the broad sense of the definition of landmass Maybe where does the difference between 3 / 4 and 2 / 3 come from?

[Ahmed]

As you point out, Christophethe oceans play a very important role in the thermal regulation of the Earth, but we should not forget the atmospheric masses, whose reactivity is much higher. the thermal inertia of the oceanic masses alone would be incapable of operating correctly the distribution necessary for life.
In fact, the two actions are complementary; in addition, water makes a massive contribution to atmospheric phenomena, in the form of vapor and latent heat (phase change).
