Copenhagen climate change conference: 7 Dec 2009-16gg This blog is a mix, like me: a combination of things, considerations, thoughts. So many recipes, of course, because I love cooking. It is not only a foogblog.
is why today I would like to talk about the weather.
delicate topic these days, I realize that I have neither the skills nor the knowledge to speak in more detail and scientific. But yesterday, I attended a lecture at the university, all'ULB, where two ice scholars explain the data collected in recent years, and where an economist (I think ) spoke of the necessary measures to be taken, costs incurred to support and etc. ..
I state that I understand to be the views of some, many people said that this climate history is all a hype, the data are so exaggerated. That's why I'd like to come with you to know what you think, if there is someone who has different opinions on these or if you know some deepening topic or explain a bit 'better things ...
Secondly, this post is based on my notes taken during their speeches: I think I've marked everything, but you have the patience to be wary still a bit 'that carry data and not take them at face value. Familiarize yourself elsewhere if the topic interests you.
I would just bring your attention to the subject, giving un'infarinata on the thought of one of the many voices that are raising questions.

start with the issue that we always talk about: the temperature ! The actual elevations, abnormal when compared to previous recordings, there are, it must be emphasized, however, that the warmest years had so far are those between 1990 and 2007. The total temperature has risen by 1.6 °, and appears to be growing: scientists estimate to reach the 3 rd more in 2020.
Now, a rise to 2 ° may also be acceptable vegetables grown longer and wider areas, winters less cold and summers are cooler, but even a lot more rainfall in total ... The important thing is not to exceed these fateful 3rd, that would cause serious environmental problems, and people who live there.
Regarding the sea, there are some points to note: there were increases in temperature up to 3000 meters below the water level, and this heat causes a sort of expansion of the level of the latter. The latest calculations include raising the current level of the oceans by 90 cm by 2100, when in 2000 the same study had limited growth at 20/50 cm. Leaving aside the problems that lead to social quest'innalzamento (rivers like the Mississippi are very low, and flow in the lowlands inhabited by millions of people in India alone, the delta of the Ganges, about 400 million people), the climate would change considerably: frequent and abundant rainfall, storms and bigger waves. If
let alone ice, first of all you need to divide them into categories we
- the ice: almost the ice water to be clear, that the North's task is to reflect sunlight
- Permafrost is the cups: what is it that more ice hard, which consists for example Greenland and the Arctic Circle, and often more compact, where you can build and that does not change, if not imperceptibly along the coast, where it mixes with sea ice.
Since 1979, when we have the first complete and reliable data on these components, there was a decline of 10% on the total surface of the ice, a decrease of 7% of the effective surface area and a decrease of 40% for the ice of the north. In Greenland
there has been an increase in snow in the interior due to precipitation caused by rising temperature, while on the coast we have data that record the removal dimasse icy well thicker and the approach of the ice cap (shift caused by winds and currents), which, being much thicker and less subject to temperature changes.
Regarding the ' Antarctic, there are significant movements of thick ice, of course, but much less than in the north, with its almost total isolation (his position far more central to the shell compared to Greenland keeps you cooler) . There are no accurate figures of the situation inside, because space probes are not able to record the data around the midpoint ( thing that I did not know, ihihi ).
Here I stop with the weather part, and I make a brevissimissimissimo summary of the economic / management. The
Kyoto Protocol currently in force, was signed by only 1 / 3 of the countries responsible for the largest emission of CO2, aimed at a 5% decrease in harmful emissions compared to recording in 1990, but many countries do not the respective year, and the sight of what is happening now is no longer sufficient. Need a net decrease of 40-50% by 2020 if we do not want to try to overcome the fatal threshold, partly because the climate needs her time to adjust to the fall, and it will be years before they show the positive effects on temperature .
With the production of this year we have officially released the "Framework "Concentration of CO2 recorded fall'inizio of the ages to the present day, touching the threshold of 390mg. We can not afford to exceed 430mg unless we raise the temperature and climate trascianarci behind remarkable environmental and social problems.
With propositions that countries have so far decided to bring in Copenhagen, the threshold of 2 ° will be worth well over.
E 'need to find effective measures to protect the climate and clear, and that the new countries join the Protocol as the U.S. and China, whose emissions account for 40% of total production.
A substantial aid to be allocated to developing countries , it is estimated that there will need to allocate between 104 and 118 billion dollars a year by 2020, always, dextrin development in the industrial sector, this money will follow roughly three broad areas: national coal market and international finance policy.

Rereading quickly I realize that not everything I wrote is 100% understandable, I apologize in advance! If there is anything unclear, ask, and as far as possible I will try to shed some light.
Any opinions to the contrary, for, neurte, clarifying or whatever are welcome, I assure you!
Almost forgot ...
To stay on the subject of climate and food at the same time (because yes is a different blog, but for me the kitchen is all .- D) ... those of you who use the calendar of fruits and vegetables in season? Personally I find it a brilliant thing! if you have not already, here are some sites where you can find one you like, you are fit, there is clear and nice, so you can always be well in line with what the earth gives us of course :-)
Big hugs to all
Update November 21, 11:55 am
even if on purpose,
Dida handed me this invitation gentilmentissimamente :
superbenissioechiaramente I did not understand what it is, but to me I guess the good propositions for the disposal of these wastes blessed! Now, here in Brux it is not easy, and then make a collection that still did not understand how it works, sgrunt! But I will go, perhaps to buy things with less packaging (I hate superfluous packaging), to reuse some pot and do more things with my hands in the event (such as pasta, etc. ...)! I will get the commitment, and would like a good scout: I will do my best!
