2009, the fifth hottest year since 1850

[Former Oceano]

Here is an article seen this evening on the Figaro.

Having a cold winter is not incompatible with climate change. The Gulf Stream protects us from polar winds. If it slows down we will have a climate close to Montreal (we are at the same latitude).

The more energy entering a system, the more extreme phenomena and therefore oscillations there will be.

Brief hot summer is not incompatible with cold winter.

2009, the fifth hottest year since 1850

Hard to believe as the winter has been harsh. But last year was one of the hottest years since modern weather reports began.

2009 will have been the fifth hottest year since 1850. By publishing these results, the WMO (World Meteorological Organization) confirmed what it had already suggested last October. "On a ten-year scale, the 2000-2009 period was warmer than the 1990-1999 period which was itself warmer than the 1980s," said the document. Given the uncertainties, the temperature anomaly is between + 0,34 ° C and + 0,56 ° C continues the organization which is responsible for presenting the result of global temperatures.

This type of data always seems complicated to hear when you are faced with abnormally low temperatures. This was the case of the French winter which started with a major cold spell. But also in the Scandinavian countries or in Great Britain "which experienced the longest episode of snow and cold temperatures since the winter of 1981-1982". Or even from the north of China or the United States…


A peak of 47 ° C in Catamarca

Conversely, the fall was abnormally hot in France and, throughout the year, Europe recorded "warmer temperatures than normal" further underlines the organization. Without forgetting the heat records recorded during the summer in Italy (40 ° C or even 45 ° C in July), in India in May, in northern China in June or even in Australia and Argentina with a peak absolute of 47 ° C in Catamarca.

This year was marked by average rainfall, with records in North Africa “causing enormous damage”, but counted many storms. The WMO refers in particular to the Klaus episode which swept across France, "the worst storm recorded outside the tropics in ten years", and classified at level three on a scale which counts five. It also highlights the serious droughts that hit China, most of 2009, as well as India and East Africa.

Hello

without going so far as Catamarca in Argentina, ... in a little less hot, certainly:

extract from the site http://www.linternaute.com/savoir/magaz ... ance.shtml

The villages of Saint-Christol-les-Alès and Conqueyrac in the Gard, hold the absolute record: 44,1 ° C, August 12, 2003.

Hello,

Since the subject is linked to global warming, I take advantage of it!


Has anyone seen the report "the secret of the clouds" on ARTE last night at 22:10 pm?

It was another report on the theory of global warming proposed by a Danish physicist, Henrik Svensmark, which already dates from 2007

Another theory, you tell me! Yes, but this one, I found it very interesting…

Svensmark and other scientists on his team studied natural mechanisms that occur on a large scale, in time and space. Climate change through the sun's magnetic activity, cosmic rays and the formation of the cloud layer, which regulates Earth's temperatures.

Nothing really exciting so far!

It becomes so, when by a happy coincidence, he shares these results with Geologists, astronomers and paleo-climatologists, and they manage to correlate their results on a wide scale of a few million years.

They have shown that the warming and cooling of the earth follows a cycle which depends on where it is in our galaxy. If I understood correctly, our solar system makes the complete tour of our galaxy in a few ??? million years, as the earth revolves around the sun in 24 hours and the sun takes 00 year ... Only, our galaxy has 1 large spiral arms and a smaller one in which we are currently. And every time our solar system is in a spiral arm we experience a cold climate. Outside, it's a warm climate, which we are currently heading towards.

So in short, whatever we do in the future, because our activity has very little influence, warming will take place and we will have to adapt.

I think these results are not being shouted for several reasons:

This would discredit many scientists and politicians. That is not a bad thing, however;

It would certainly not be good to say: "Go ahead, pollute, it hardly influences global warming? "

If this information turns out to be the reality, should it really be shared on a large scale?

Good night

+1 very interesting program. It took a long time to get published in a well-known scientific journal. It is not easy to go backwards, even in our time . Strongly that this path is explored by other independent scientists to be able to really decide on the extent of the discovery.

So in short, whatever we do in the future, because our activity has very little influence, warming will take place and we will have to adapt.

It is true, that in the long term, the warming of celestial origin is inevitable just like an extinction of mass of origin (near-Earth) as the explosion of the sun in supernova ...

By that I mean that there is, I think, a "slight" time scale problem in this "beautiful" theory ... do you know the period of revolution of the Milky Way?

Because currently we are not talking on an astronomical scale but on a human scale (200 years) ...

After we can always try to make believe that CO2 is not a greenhouse gas ... who tested it here by yourself in his greenhouse ????

[Obamot]

The truth is, probably, even "super-specialists" don't know. Even if the doubt grew during this period "relatively hot".

Because for CO2, it is apparently impossible to discern between the changes intrinsic to the "normal" activity of what is happening on the planet (those which would have occurred anyway if man were not there) and changes due to human activity.

"Only" 5% of CO2 production would be attributable to human activities, most of the rest would come from the oceans, the respiration of plants, volcanoes, etc. In other words, this is part of the "background noise".

Compared to metane, this gas would increase by 1% per year ... and still too little in the upper spheres speak of it ...

Measured in CO2 equivalent, the contribution of livestock to global warming is higher than that of the transport sector. The activity is responsible for 65% of nitrogen dioxide emissions, a gas with a global warming potential 296 times higher than that of CO2, mainly due to manure. In addition, livestock produce 37% of methane emissions linked to human activities. This gas, produced by the digestive system of ruminants, acts twenty-three times more than CO2 on warming.

The enormous advantage of the effects of global warming (if we can say ...) is that it makes humans ask all the pointed questions relating to its impact on the environment.

Let us remember that this global awareness is due to global warming (for example the "Peak oil", which everyone did not care about twenty years ago, except these "super-specialists").

Not so long ago, "green" people were still considered "folklos" People like Hulot, Kon Bendit and a few others would never have been able to shake the political landscape. Today yes!

Hello everybody

I hope you all had a nice Easter day.

Thank you Christophe for your remark, because it is very relevant.

By that I mean that there is, I think, a "slight" time scale problem in this "beautiful" theory ... do you know the period of revolution of the Milky Way?

It is true that when I discover a report like the one I quoted above, which brings us a lot of new data, I tend to detach myself from the human time scale.

What does the duration of our lives represent in the face of the period of revolution of the milky way which is a priori greater than 200 million years?

So proving that we are going out of a spiral arm, and that we are going to return to a warm period, that nothing will stop the warming, it is a very good performance. Well done, M Svensmark.

But will it concern me? Or will it only concern the grandchildren of my grandchildren? In any case, it will remain celestial mechanics. Let's just hope that humanity will have the intelligence and the ability to adapt to this change.

So, while waiting to plant orange trees in Iceland, I think it is wise to continue our efforts to preserve the little blue planet.

The problem is that the earth has warmed in a few decades.
A celestial impact (whose scale is expressed in millions of years, as you say) cannot explain the sudden variations that we know

[beafiliberti]

Speaking of sudden changes, what do you think of the last earthquakes in South America? Concern me enough, by that since we we have to bring the minimum, I walk in my electric bike and I refuse to cars!
