Scientists believe that even if we stop emitting greenhouse gases today, the amount of CO2 and other gases in the atmosphere will continue to cause global warming for another 100 years, that temperatures could rise an extra 6 degrees?
Since 1970, the earth’s average temperature has risen by 0.8 degrees Celsius. By estimates, by 2100, the earth’s average temperature will rise by 5.8 degree Celsius, a rise compared to that between the last Ice Age and today. A rise to such an extent will create a world far different from the one we know. Such a huge rise in global temperature will diminish crop yields, melt the snow/ice reservoirs in the mountains that feed the earth’s rivers, cause more destructive storms, increase the area affected by drought, and cause more frequent and destructive wildfires.
A rise in temperature on a global level will not be uniform; it will be felt more over land than over oceans, in the higher latitudes than over the equator, and in the continental interiors than in coastal regions. With a 5 – 6 degrees rise in global temperature, water availability in Southern Africa and the Mediterranean could drop by 30% – 50% and African agricultural yields would drop by 15% – 35% as a result. Up to 80 million more Africans could be exposed to malaria and another 7 to 300 million people would be affected by coastal flooding.
Higher temperatures mean that heat waves are likely to happen more often and last longer, too. Heat waves can be dangerous, causing illnesses such as heat cramps and heat stroke, or even death.
The Earth’s global temperature has risen 1.4 degrees Fahrenheit since the industrial revolution
With the current trend, your favorite beaches would soon disappear, and so will the snow-covered peaks where you like to ski so much. Your favorite food could also disappear as many animals and plants would go extinct, unable to adapt to such a drastic change in the climate. The ecosystem could collapse too with the loss of habitat of various animals. All these points to a very bleak future for our planet earth.
