Climate Crisis

Yesterday, I went to the San Mateo Public Library to see Taylor Francis' presentation entitled Climate Crisis. I learn that CO2 and Temperatures follow the same patterns, when on rises so does the other, and that's what has been happening to cause Global Warming. As human activities emit carbon dioxide, it builds up in the atmosphere trapping more and more heat and the planet itself begins to get hotter. The hottest year so far was the year of 2005. The rising global temperature has caused wildfires and huge heat waves in Europe and America, killing many people, crops, and livestock. The temp. of the worlds oceans is also rising, this time causing enormous floods and there's been a doubling of the amount of category 4 and 5 storms in the last 30 years (because the heated water increases wind velocity and air humidity, perfect storm conditions). Global Warming also allows diseases to spread faster and to more areas as their carriers tend to prefer warm climates. The lack of food and water (caused by drought and heatwaves) creates an environment where conflicts are very likely to break out. The ones that are being and will be hit worst will the be poor, making Global Warming a social justice issue as well. The Arctic Ice Cap used to be a cooling pocket that helped keep the entire planet's temp. down and kept it's own ice frozen. In recent years, it has turned from a cooling into a heating pocket as the temp. rises, the ice melts and instead of reflecting the suns rays, the water (melted ice) absorbs the heat, warming the water that surrounds the ice, causing it to melt faster and faster and then cycle repeats again, a feedback loop. Ice that floats on water and melts does not cause the water level to rise, however ice that was on land, melts and flows into the oceans (water) does cause the water level to rise. Such areas of land-based ice are Antarctica and Greenland. If we keep emitting at the levels that we emit now the sea level could rise up to 20 ft in coming years. There is no longer a debate about the existence of global warming, now it is a debate about what to do about it. In about 15 years we will reach a point of no return, so we have to focus on what we can do now. We can use wind power, hydraulic power, solar power, natural gases and bio fuels. The government, the businesses and the people all need to act so that there can be a real change for the better! =)
