By 2070, we estimated that the level of CO2 that is in the atmosphere could increase to 300 PPM! If there is much talk of the possible disadvantages associated with this increase, the supposed global warming, for those who still believe that CO2 follows temperature, we speak very little of the benefits that result from this increase then !
Here are a few:
According to data that were collected by 20 studies, an increase of 300 ppm CO2 increase crop yields of maize by 21.3% !
Here are a few:
According to data that were collected by 20 studies, an increase of 300 ppm CO2 increase crop yields of maize by 21.3% !
According to data that were collected by 235 studies, an increase of 300 ppm CO2 increase crop yields of wheat by 32.1% ! !
According to data that were collected by 182 studies, an increase of 300 ppm CO2 increase crop yield of rice by 34.4% !
According to data that were collected by 179 studies, an increase of 300 ppm CO2 increase crop yield of 46.5% soybean !
more the world population increases, the amount of CO2 that is released in the atmosphere increases, which allows for better agricultural performance and, therefore, the ability to feed more people! !
A pretty self-regulatory mechanism, which !
ago, only 35 million years, says Associate Professor, Division of Experimental Medicine Department of Medicine, McGill University, Dr. Michael Laughrea, the concentration of CO2 was 840 ppm higher than now!
There are ten things that are essential knowledge on climate:
1) A tropical climate or a climate that is warmer is great for agriculture: it is a fact that Brazil is more productive than United States, regarding the cultivation of soybeans and cotton!
2) In the Middle Ages, it was, almost, as hot as it does now!
3) A warming climate does not only have effects that are negative!
There is, in fact, many advantages to global warming, for Quebec, either in terms of traffic, in terms of auto mechanics in terms of snow removal, in terms of reduced heating, in terms of agricultural production and forestry production, which would be increased in terms of greater sustainability of our roads, in terms of greater aviation safety, etc..!
4) During the previous interglacial period, there is of that, 125,000 years, Earth's temperature was 6 ° C warmer than it is now!
5) Despite the interglacial period of 125,000 years ago and was very hot, it did not prevent 15 000 years later, the fact that Quebec will be solved completely, within 1 km of ice, and this for nearly 100 000 years in a row!
6) The concentration of CO2 in the atmosphere is, currently, three times less that 35 million years ago!
7) A global warming raises sea levels! This rise lasted from 12,000 years! She was 20 cm during the twentieth century: 12 m since 8000 years! It will, presumably, 40 cm, during the twenty-first century! We survived without too much pain, to 20 cm rise in the twenty-first century, and the 40 cm rise in the twenty-first century will be boring, but boredom will pale compared to problems that are much more important and which are, above all, more soluble, such as access to drinking water, waste management and the fight against real pollution, among others!
8) Nine in ten years, Quebec finds itself completely, within 1 km of ice, and have been 3 million years, what is called the ice ages! Only a warming climate could liberate us This fatality: basically, there were 30 who were successive ice ages, from 3 million years, and each era, which is normal, for Canada, being separated from the next era, for a brief period hot weather for an average of 10 000 years and we are in an era that is hot, since 10 000 years!
9) In 3000 BC, Greenland was 2 ° C warmer than it is today and, during the last interglacial period 125,000 years ago, the ice cap of Greenland has melted completely!
10) During the previous Ice Age, there was, in Greenland, many temperature increases that were, at times, abrupt and huge! These were the transitions Dansgaard-Oeschger!
example:
a) 14 700 years ago, there was an increase of 9 ° C in a few decades, including an increase of 2 ° to 4 ° C, in 3 years!
b) 38 000 years ago, there was an increase of 11 ° C, in 21 years!
c) 70 000 years ago, there was an increase of 16 ° C in 160 years !
In Canada, we have three benefits of a warming climate
1) The plant growth would be faster, as everywhere else on Earth!
2) Since the economic disadvantages of winter would be mitigated, heating costs are reduced, as well as insulation, snow removal, damage, because of freezing / thawing, maintenance, etc..!
3) Canada would have greater opportunities to northern people, whether by gains of scale and greater efficiency, because that country would become nothing but a stretch of 6000 km long from east to west by 200 km wide! Few Canadians live more than 200 km north of the U.S. border !
fight against global warming, if there really is one??
This, then, a Think it !
