The History of Global Climate Change

The Earth experienced many dramatic climate change events at various times in the history of the earth. For the time being, the whole planet was covered with ice, but it was hot and dry for a while. In this respect, the Earth experiences at least three major long-term cold weather and ice age and is dotted with warm climates. Recent ice age is the result of the present glacier that occurred during the last years of Pleistocene, about 110,000 to 10,000 years (Clayton, 1997).

In the last three episodes of our history of evidence of global climate change, we found that in the last episode more than 40% older than the experience before full industrialization of human species Measurement of atmospheric CO2 record of the earth Focus on. However, we have not examined the global temperature measurements since the third episode, such as the courageous steam engineer Guy Callendar (1961) and Landsberg & Mitchell, Jr. (1961) Slightly visible but distinguishable warming during 1880 was measured independently. Late 1950s. You can also recall from the third episode that physicist Gilbert Plass used some of the first computers to improve the calculation of carbon dioxide for infrared absorption. A climate change obvious influence is also observed when it rises once.

Climate change is a global phenomenon that has occurred since the earth was formed. In the past decade, climate change has become a scientific and political big problem. There are obviously hot and cold times in the history of the earth's climate, but these changes have been observed relatively rapidly in the world in the past 150 to 200 years. For modern human society, the soil seems to be more important than ever in order to meet the global demand for food and fiber to increase the limited soil resource population. Climate change threatens the world food security. Countries like India are more vulnerable given the tropical climate and the poor cohesiveness of small farmers and marginal farmers. Climate change is expected to have a major impact on agriculture through direct and indirect effects on crops, soils, livestock and pests. The main impact of climate change is achieved by increasing carbon dioxide and increasing temperature.
