Awareness2007 on the causes of Globalwarming : The greenhouse gas

Posted on janvier 27th, 2007 by Globalwarming awareness2007.

The atmosphere of the Earth retains heat partly that the sun brings to him, and have a globalwarming, it is the awareness2007. Gases called for purpose of greenhouse emitted by the human activities, whose for 60% (and in increasing proportion) carbon dioxide coming from coal, oil and waste gases, has intensified this phenomenon for two centuries (with a feedback of the temperature which increases in its turn the CO2 concentrations and will do a globalwarming after 2007).

 

The awareness2007 is the globalwaming of earth

Where is our awareness in 2007 …
According to the third evaluation report of the GIEC, founded in 1988 by the United Nations under the double American and British impulse and whose results constitute since the engine of the international negotiations: it is certain that the carbon dioxide concentrations in the atmosphere have reached levels ever seen for 420.000 years and evolve/move for two centuries at a speed ever recorded for 20.000 years [1]; the speed of the phenomenon observed (more than one half-degree in one century on the sphere, thera are a globalwarming) and awaited (of 1,4°C at best with 5,8°C moreover, on average total, into 2100) is hundred times higher than the naturally printed variations with the climate of the Earth by its parameters astronomical and translated in alternations between glacial and interglacial eras (a few degrees in 10.000 years each time); it is practically certain (more than 99% of probability) that emitted fossil CO2 will influence in a determining way the CO2 concentrations of the atmosphere, in front of any other source, during all the 21st century: if the annual average temperature of the sphere can rise from here 2100 of 1,4°C with 5,8°C, the third with a small half of this variation comes from uncertainties on operations planetary biophysics, all the remainder depends on the policies which will be adopted in the very next decades by humanity; it is very probable, and our awareness2007 say(from 90 to 99% of probability) that the climatic disordered state will cause longer and more intense heatwaves and globalwarming, with a particular rise in the night temperatures; it is very probable (from 90 to 99% of probability) that increasingly intense precipitations and especially increasingly variable one year on the other will follow, in particular in the average latitudes.
Globalwarming Awareness2007 is our fight!

Globalwarming, awareness on a lac in 2007

The consequences of a Globalwarming which one knows now that it is likely to develop and to be prolonged are likely to be heavy for humanity. Scientists, policies and citizens are overall conscious of the need for taking measures to limit the reheating of planet, but often individually not very inclined to apply their ideas.Since the Summit of Rio, which invited with the international responsibility to safeguard planet, the awareness of the climatic change took place, and of the strategies were proposed to limit the emission of gases for purpose of Globalwarming. The protocol of Kyoto which treats this aspect is nevertheless in a dead end, because of the refusal of signature on behalf of country whose industrial activities are strongly generating gas for purpose of greenhouse. In France, following a private bill emanating from the Senate, a national observatory on the effects of the Globalwarming and the climatic reheating in Metropolitan France and in the departments and overseas territories was created in 2007.The awareness2007 is a campaign against the Globalwarming was set up by the French ministry for ecology and the durable development, with for objective ensuring in a first stage the stability of the emissions of gases for purpose of greenhouse, then to fall under a reduction of these emissions.

Forests, agricultural lands can reduce global warming?

Forests, agricultural lands, and other terrestrial ecosystem offer significant carbon mitigation potential. Although not necessarily permanent, conservation and sequestration of carbon may allow time for other options to be further developed and implemented.

Awareness2007 of Forests destruction

We have awareness of biological mitigation can occur by three strategies:

  1. conservation of existing carbon pools,
  2. sequestration by increasing the size of carbon pools,
  3. substitution of sustainably produced biological products, e.g. wood for energy intensive construction products and biomass for fossil fuels.

Conservation of threatened carbon pools may help to avoid emissions, if leakage can be prevented, and can only become sustainable if the socio-economic drivers for deforestation and other losses of carbon pools can be addressed. Sequestration reflects the biological dynamics of growth, often starting slowly, passing through a maximum in 2007, and then declining over decades to centuries.

 Marmot and global warming awarness in 2007

  • Land animals

Reindeer are expected to disappear from large portions of their current range by the end of the century.

Marmots are ending their hibernations about three weeks earlier than they did 30 years ago.

Canadian red squirrels are breeding about 18 days earlier.

Red foxes are spreading northward, encroaching on territory normally occupied by their artic cousins.

North American Fowler’s toads are breeding six days later than they did a decade ago.

Polar bears today are thinner and less healthy than those of 20 years ago.

  • Sealife

Coral reefs around the world are predicted to increase by up to a third in size.

Elephant seal pups are leaner because their prey is migrating to cooler waters.

Loggerhead sea turtles are laying their eggs about 10 days earlier than they did 15 years ago.

Rising temperatures are influencing the sex of Hawkbill turtle hatchlings, with more females than males being born.

Tidal organisms like rock barnacles, mollusks, and tidal snails commonly found in warm southern waters are moving northward.

Many fish species are moving northward in search of cooler waters.

  • Birds

The diet of some songbirds are changing, with some avoiding insects that consume leaves exposed to high levels of carbon dioxide.

North American tree swallows are laying their eggs about nine days earlier than they did 40 years ago.

Common murres are breeding 24 days earlier than they did a decade ago.

  • Plants

Some plants are thriving in areas where their growth was limited before, thanks to temperature changes that provide more water, heat and sunlight.

American flowering plants like columbines and wild geraniums are blooming earlier than before.

  • Insects

Edith’s checkerspot butterflies are moving northward in search of cooler temperatures.

A gene in the fruitfly Drosophila normally associated with hot, dry conditions has spread to populations living in traditionally cooler southern regions.

In 2007, what extreme events could global warming explain ?

Posted on janvier 16th, 2007 by Globalwarming awareness2007.
Categories: globalwarming.

As the world warms, some extreme climate events, like the frequency of heat waves and very heavy precipitation, are expected to increase, but it remains uncertain whether or not to expect changes in the frequency of some other extremes. Moreover, it is important to note that it is not possible to link any particular weather or climate event definitively to global warming . The causal linkage, if any, between the frequency of extreme events and global warming only can be determined through statistical analyses of long- term data, because the natural climate system can produce weather and climate events that often appear to be uncharacteristic of the recent climate.

Awareness of the man has it the capacity to avoid globalwarming in 2007?

Trees in the globalwarming awareness in 2007In 2007, the globalwarming awareness is in the center many debates but also been the subject of many controversies. The human activity is shown finger like the essential factor of this reheating. Certain scientists and ecologists draw the bell from alarm.

Since the man appeared, it always thought that it could modify his environment and work the Earth according to his goodwill. Today still, many which is those believe that our simple will can avoid us the climatic catastrophes to come. Personally, I do not share this analysis of the facts. Not that the human activity which is particularly polluting should not be reduced to the maximum but, I doubt, whom that is enough to modify the future.

Indeed, one can really apprehend the future only by knowing the past. However, the evolution of the climate of the Earth is registered under our feet. Obviously, the climatic evolution is marked by cycles, immutable, which depend on several criteria which, them, are completely independent, of our will.
