Question
If ust the risng man-made CO2 emission is what causes the Global Warming? Critical thinking at the free university- free from state, market and profit. Pro-global warming lobby insists that it is now CO2 which is driving the rise in temperature with no hard evidence to support this illogical premise. On the contrary, temperatures rose fairly rapidly from about 1900 to 1940 but then declined until the late 1970s during a period when CO2 emissions were rising in the post-war industrial boom According to satellite data, following peak temperatures in 1998 there has been no warming of statistical significance in spite of a further increase in CO2 emissions. 95% of greenhouse gas is water vapour, CO2 is a relatively minor constituent making a marginal contribution to the greenhouse system Studies acknowledge that rises in CO2 concentrations have a warming influence but that it is logarithmic, ie. the first 20 parts per million have the most effect but thereafter the influence wanes to negligible by the time the current 393 parts per million are reached. CO2 concentrations have been much higher in the past CO2 is beneficial for promoting plant growth which is important if we are to feed the growing global human population without destroying our environment. Below 150ppm nothing would grow and we'd all die. Dutch growers buy CO2 to increase concentrations in their greenhouses to increase crop yields. So it seems perverse to describe a basic building block of life on earth as a pollutant Finally, while acknowledging that the earth's climate is a complex system with millions of variables, the correlation between solar activity and temperature appears much more compellingExplanation / Answer
According to Article ,Studies reveal that what we say that global warming which has been posed as global future threat is not only problem that is real threat to earth.There are other environmental mechanisms that is affecting our earth's climatic balance.As per studies CO2 produced by human activities is not at alarming rate.CO2 do not form most part of greenhouse emissions that is raising temperature of earth.
Watervapor form most part of greenhouse gas so we cannot criticise only humans interference for climating disbalance.Global cooling is also a phenomena that is also global threat but not paid much attention as global warming.
