Climate Change: What Do Scientists Say?|5 Minute Video
Climate change is an immediate topic of discussion amongst celebrities, politicians and journalists … however what do researchers say about climate modification? Richard Lindzen, an MIT climatic physicist and one of the world’s leading climatologists, sums up the science behind environment modification.

Script:
For 30 years I taught at MIT, throughout which time the climate has altered incredibly little bit. It seems that the less the climate changes, the louder the voices of the climate alarmists get. Let’s clear the air and develop a more accurate picture of where we really stand on the issue of global warming or, as it is now called–” climate change.”
There are basically three groups of people dealing with this issue. Groups one and two are scientists. Group three consists mainly, at its core, of politicians, environmentalists and the media.
Group one is connected with the scientific part of the United Nation’s International Panel on Climate Change or IPCC (Working Group 1). These are scientists who primarily think that current environment change is mainly due to man’s burning of nonrenewable fuel sources– oil, coal and natural gas. This releases C02, co2, into the environment and, they think, this might eventually dangerously heat the world.
Group 2 is made up of scientists who don’t see this as an especially serious problem. This is the group I come from. We’re generally referred to as doubters.
We note that there are many reasons why the climate modifications– the sun, clouds, oceans, the orbital variations of the earth, as well as a myriad of other inputs. None of these is totally comprehended, and there is no evidence that CO2 emissions are the dominant aspect.
However in fact there is much agreement between both groups of scientists. The following are such points of contract:
1) The climate is constantly changing.
2) CO2 is a greenhouse gas without which life in the world is not possible, however adding it to the environment ought to cause some warming.
3) Atmospheric levels of CO2 have actually been increasing considering that the end of the Little Ice Age in the 19th century.
4) Over this duration (the past two centuries), the global mean temperature level has actually increased a little and unpredictably by about 1.8 degrees Fahrenheit or one degree Celsius; however only given that the 1960’s have male’s greenhouse emissions been sufficient to contribute.
5) Given the intricacy of environment, no positive prediction about future international mean temperature or its effect can be made. The IPCC acknowledged in its own 2007 report that “The long-lasting prediction of future environment states is not possible.”

Environment Change: What Do Scientists Say? Climate modification is an immediate topic of discussion amongst reporters, political leaders and stars … but what do researchers say about climate modification? It seems that the less the environment changes, the louder the voices of the environment alarmists get. Group one is associated with the scientific part of the United Nation’s International Panel on Climate Change or IPCC (Working Group 1). These are researchers who mainly believe that recent environment modification is primarily due to guy’s burning of fossil fuels– oil, coal and natural gas.
