I believe that the world is warming. From our readings it sounded like both of them believe at this point the world is warming or at least no cooling off. Global warming really isn't much of a debate in my opinion. I have researched studies which shows the world has warmed up about .5 a degree in the last century. What is really being debated is how drastic is this change going to be. lindzen suggests that with the increase in tempature today will cause an increase in the cloud cover around the earth in the future. The evaporated water (clouds) reflect much of the suns rays reducing the amount of heat the earth absorbes. He brings up a good point that without any of the green house gases the earth would be very cold about -17 degrees celcius i believe he said. Maybe the change will actually be positive and help plants and animal in general survive. If the global warming continues plants and animals might not be able to adapt to the their changing environments. Maybe after ths cycle of extra heat we will find ourself in a cooling period and nature will correct itself. Mr. Lindzens arguments are interesting and compelling. His job title shows that he should know what he is talking about and gives lots of examples. With the fact that their are a lot of negitive and positive feedback working simaltinously it's hard to predict weither green house gases like carbon dioxide are causing global warming. Also it would be interesting to not that at some point the addition of green house gases might cause a spiral of tempurature constantly rising, or the addition of green house gases like carbon dioxide will have absolutely no effect. Those are 2 extreme cases which I don't believe we will reach either one. I also believe that political pressure has been put on the scientists to find the results the people want to hear, "the world is going to end". Every chance you get you hear that it's going to be the end of the world. I already lived through the new years of 2000 when all the computers stopped, no body had electricity, no clean water or food to eat for weeks on end. I feel like humans in general are to often going around trying to fix problems and when their aren't any we think up our own to try and fix. That way at the end of the day we can all go home and snuggle up in our nice, comfy beds and feel good about ourselves.
