Journal Entry: The Most Important Number on Earth The article “The Most Important Number on Earth” states that the world is in a crisis at the moment. The carbon levels in the atmosphere are at about 375 and should be at about 350. The first time that we found that global warming was taking place was in 1988. James Hansen told congress that coal, gas, and oil were warming the earth. This has become increasing a problem for the world. The arctic ice caps are melting and raising the sea levels around the globe. The estimate for when the arctic icecaps will be completely gone is now 2012. At first the estimate was by 2070 the ice caps would be completely gone. Many scientists say that we are either at the “tipping point” or past it. As the permafrost is melting, methane is being released into the atmosphere speeding up global warming. And as the ice caps are melting, the ice is reaching a state at which it is too thin to be able to hold on to the ice that is below it. The bottom of the ice is

The time for action is now but to take action the politicians in power must change their policies. The knowledge has to be spread according to the article. This could be disastrous to the environment because many species would disappear because of the ice caps melting. The sun’s rays would not be reflected off the icecaps back into space and the earth would progressively get hotter and hotter. Temperatures would rise to unbearable heights and in many places life would be unsustainable. In short we are hurting ourselves in the future by continuing practices that are keeping us economically stable at the moment. Our physical lives are being affected at the cost of our economic wants....
