Climate: a hot 2010 summer in Western Europe




by Christophe » 13/07/10, 16:26

... and it's not just about Spain ...

Western Europe is preparing for a very hot summer
Stéphane Foucart and Pierre Le Hir LEMONDE | 05.07.10 | 14h59 • Updated the 05.07.10 | 15h00

Since 2003 and its deadly summer, the French government is preparing, at the beginning of each summer season, to face possible waves of intense heat. The high temperatures of these last days are, again, fear episodes of heat wave during the summer.

A brief alert was also launched for the Rhône-Alpes region on Friday, July 2. The day before, the Minister of Health, Roselyne Bachelot, had announced that the heat wave plan - which since 2004 has been automatically activated on June 1 - would be reinforced. Regional health agencies will be asked to be particularly vigilant so that hospitals are not overwhelmed in the event of a heat wave, as was the case in 2003. It is to them that the director general of the health will transmit the warning messages issued by Météo France and by the health watch institute so that they can organize, without fault, "the permanence and continuity of care," explained the minister.

In fact, Météo France's seasonal forecasts anticipate, for the months of July and August, temperatures that are generally above seasonal norms over the whole of Western Europe. Which means likely heat waves. Most models "forecast precipitation amounts below seasonal norms," ​​Météo France cautiously anticipates in a press release published in early June. In which case tensions in the management of water resources in the north-west of metropolitan France cannot be ruled out.

Air temperatures over Western Europe are closely related to that of the Atlantic Ocean. However, explains Christophe Cassou, researcher (CNRS) at the European Center for Advanced Research and Training in Scientific Computing (Cerfacs), "the" hot anomalies "observed over the entire tropical Atlantic are the strongest ever observed".

Over the past thirty years, the last record for heat in this ocean basin, reached in 2005, had seen surface waters warm by 0,9 ° C above average. Today, this "hot anomaly" reaches around 1,5 ° C.

The hot summer that is coming is, in part, the repercussion of the particularly cold and long winter which preceded it over Western Europe and the Atlantic basin. "We had a particularly atypical winter in terms of atmospheric circulation, explains Mr. Cassou. The virtual absence of the Azores high pressure has led to a weakening of the easterly winds, the trade winds. Suddenly, these have less blew over the Atlantic, which was able to store more heat. "

An unusual amount of energy has accumulated over the first fifty meters of the tropical Atlantic. This situation has not only an impact on the air temperatures in Europe: it also promotes the birth of cyclones which, formed off West Africa, come to strike Central America. These complex atmospheric phenomena can only be formed when the surface waters of the ocean exceed 27 ° C or 28 ° C.

2010: record year of temperatures?

According to the US National Climatic Data Center (NCDC), the first five months of the year 2010 have been the hottest since monthly temperatures began to rise in the late nineteenth century. This suggests that 2010 could be the hottest year ever recorded.

This situation is partly due to the phenomenon El Nino which has been installed since the beginning of the year on the tropical Pacific. Another indication of abnormally high temperatures is the reduction in the extent of the Arctic sea ice. At the end of June, it was about 250 000 km2 lower than its June 2007 level. This year already marked a record with over a million km2 lost compared to the average 1979-2000.

Finally it seems that we admit that climate change has an impact on the climate of our regions ...

Since early March (where he made 25 ° C home) I felt that summer would be hot ...

This is the 1ere time also I hear on TV an engineer from France weather talk about the link between warming and climate in France ...

But it's probably too late to say ... :|

Britain is thirsty

The 2010 year puts a bad light on the cliche of a green Britain, where showers are not rare. Thus, this year, the rainfall deficit is exceptional and record for the first six months, since more than 80 years. With a cumulative 356,8 mm of rain from January to the end of June, we are far from 511,7 mm average over the period 1971-2000. It is necessary to go back to 1929 to find a first semester drier (275,7 mm of rain).

Compared with this period, the demand for water has obviously increased considerably with the sharp rise in the population and growing industrial and agricultural needs. As a result, the level of groundwater and other freshwater supplies is exceptionally low, with recharge rates of only 50% in the most affected areas.
If the west coast of the country is the most concerned, especially the Northwest, the situation of the Count of Cumbria is paradoxical. This region was indeed part of the areas flooded a few months ago. However, if the current levels of rainfall continue, it should soon know a restriction of water uses, its resources fueling millions of homes, including the city of Manchester.

And one more:

The month of May confirms the climatic trend observed since January: the year 2010 could well delight 2005 the status of the hottest year since 130 years. This is evident from the latest survey conducted by James Hansen's team at the Goddard Institute for Space Studies (NASA).

The graph above (click to enlarge) shows global maps showing the temperature anomaly relative to the average calculated on 1951-1980. The curve shows, in red the year 2010, a comparison with the years 1998 and 2005 as well as the hottest months recorded when it is not a question of these two years there.

The maps show that the contribution of the El Niño / La Niña oscillation is becoming weaker, with a decreasing red spot in the tropical Pacific, especially when compared to that of 1998. It is possible that for the second half of 2010, the oscillation plays in the opposite direction with a cooling of the East Pacific, as the latest forecasts of oceanographers seem to indicate (see here a note on the latest El Niño news).

Are not the only ones!

Lack of water

There is about one meter of water missing in most lakes in the La Vérendrye Wildlife Reserve. This is the case for Lakes Victoria and Granet, as the reservoir Dozois.

The situation is also problematic for the Ottawa River watershed. The Quebec Center for Water Expertise (CEHQ) has even issued a warning for Lac des Quinze in Témiscamingue.

Recreational boaters navigating the lake must exercise caution to avoid danger, such as shoals that are no longer submerged.

The water flow of the Quinze dam is also lower than usual. The CEHQ considers that it still allows to maintain a sufficient level to supply the water intake of the municipality of Angliers throughout the summer.

The thin snow cover accumulated over the winter and the low rainfall in recent weeks have prevented the lake basin from reaching its normal level for the summer season.

La Vérendrye Wildlife Reserve

The Quebec Outdoor Establishments Society (SEPAQ) has had to develop new launches in the La Vérendrye Wildlife Sanctuary to allow fishermen access to water bodies.

The director of the wildlife reserve, Serge Martel, indicates that several launches had already been laid on the Dozois reservoir, which facilitates the situation there.

He added that the Old Mill area of ​​Lake Victoria is more difficult to access. "The Old Mill, which is a small launch at the entrance to the reserve, is a small river corridor that leads to Lake Victoria. It's always closed, "says Serge Martel.

The CEHQ website tracks the behavior of certain bodies of water in real time.

Rio Tinto Alcan launches an SOS
Updated: 08 / 07 / 2010 22h40

Rio Tinto Alcan is calling for help from Hydro-Québec. The company urgently needs energy because its basins are almost dry in Saguenay-Lac-Saint-Jean.

"We are in a state of energy shortage, which could jeopardize aluminum production," says Étienne Jacques, vice president of Rio Tinto Alcan.

To supply its plants with electricity, Rio Tinto Alcan operates its own dams in Saguenay-Lac-Saint-Jean. But its 75 000 square kilometers of water surface - the equivalent of New Brunswick - is no longer enough for the task at the moment.

"During 9's last 10 months, we have received far below all normal rainfall," says the company's vice president. Such drought is expected only once in 1000 years.

The aluminum smelter, which has enormous electricity needs, is currently using Hydro-Québec for its production needs.

"We are no longer able, from the current situation of our basins, to meet the expenses of factories," says Serge Bouchard, director of electrical energy at Rio Tinto Alcan.

Since February, the company has managed its dams drip and has already borrowed Hydro-Québec 500 million kilowatt-hours, the maximum expected. That's why the company is now asking for an extra block of electricity.

Jobs at stake?

"If, for example, we had no energy for the coming weeks, that is to say that in September, we will have to make difficult choices," says Rio Tinto vice president. Alcan.

All the assumptions are on the table: production stops at the early closure of the Shawinigan plant.

The Minister of Natural Resources is desperate to avoid this scenario. "I ask Hydro-Québec to support the accelerator so that we can really have an agreement that is sealed as quickly as possible," says Nathalie Normandeau. There are jobs at stake. "

Hydro-Québec also confirmed that an agreement was imminent for a block of energy from 300 megawatts.

Here is the heat wave since 1 week and it continues for another week!

The air conditioning and the pool are on!

It would not be due to the chemical spraying of the Chinese to rain to fill their damned dam! : Evil:

I do not know if your remark is serious, but it would be necessary that the Chinese are crazy to link given the high price of the salts of agent and the spraying by planes or rockets ... this type of practice is used in China and in some African countries in the case of a significant deficiency for agriculture ... As for the anti-hail effect, the system is statistically ineffective, moreover it is not used at all in Alsace for example ...

Lol obamot!

14,2°C
This is the average temperature of the last six months on Earth. And the strongest ever recorded.


14,2 ° C. Let 0,68 ° C be little more than the average of the 20th century. Or the highest average temperature ever recorded, according to measurements from the US Agency for the Ocean and Atmosphere (NOAA). Gulp. Should we see the sign of climate change? Experts are cautious and recall the re-emergence of the El Nino phenomenon that may have contributed to the increase in temperatures in 2010.

Still, "very strong temperatures are consistent with what can be expected," said climatologist Hervé Le Treut to AFP. Nevertheless, according to the NOAA, June 2010 was the 304e consecutive month overall warmer than average on the 20th century. "That makes 25 years of anomalies. There is talk of climate, not weather. The world is warming up very fast, "said British climate scientist Andrew Watson. This is not the misfortune of everyone.

Less hot and dry than 2003 in France !!

And especially much less hot than there is 125000ans, with 2 3 ° C more, the seas 3 to 5m higher (more from Bangladesh), the southern half of melted groendland and all without human CO2 and much less CO2 !!!

Goendland is still not green as around the 800 years (green country)!
