Do you believe in Global Warming? Why or why not? And how can you explain 20+ yrs ago's idea of Global Cooling

Answer 1

There is a measurable increase in the thermal energy available in the Earth's atmosphere. The evidence strongly supports the idea that it's due to human intervention, particularly the massive consumption of fossil fuels - releasing in a few decades carbon that took millennia to be stored away. The increased carbon in the atmosphere allows it to retain more of the heat coming in from the sun.

Global cooling was a different interpretation of the overall trend based on the information they had at the time. Basically some scientists thought the most immediate result of air pollution was going to be more sunlight being reflecting back into space and a cooling of the earth's surface. That may still be the long term result as a period of warmer temperatures drives more water vapor into the upper atmosphere.

Overall it's probably more correct to refer these phenomenon as global climate change.

Answer 2

Yes. I am intimately familiar with research on paleoclimatology. Whenever the Earth has had an atmosphere with a high count of CO2 you have had global warming. High counts of CO2 have historically been caused by supervolcanic events. The burning of fossil fuel is now adding about 2ppm of CO2 into the air every year, which mimics the amount that a supervolcanic event could add. Without the added CO2 we would probably be going through a period of global cooling. There was a single report some 30 years ago about the prospect of global cooling, but that does not compare to the substantial body of vastly more sophisticated work that now exists on global warming.

Answer 3

You don't need to believe in it to be worried about the possibility.You see if there is any evidence at all there may be no way out for us all; because the fact that everyone awake knows is that ice caps are melting and that average world temperatures are rising.Cold water is more able to dissolve carbon than warm water (fact.ever tried warm fizzy drink)so warmer ocean surface temperatures mean less sea vegetation so less food for it's ceatures so less for us.Warmer muskegs in Canada and Siberia mean huge releases of methane(a global warmer much more powerful than poor old CO2.These processes gee each other up.IF THE GLOBAL WARMING PROCESS IS HAPPENING IT IS AN EXPLOSIVE ONE.
I have been a scientist most of my life and I dont accept that the global warming theory is proved but I have never seen before such a large body of evidence disproved.Good luck all youse guys,I'm past retirement age
so I can only hope you all don't get what seems very likely.

Answer 4

Global warming is completely real, and people who disagree with it are ignorant. With all the chemicals, such as CFCs(chloroflourocarbons) getting pumped into our atmosphere it causes our o-zone to deplete. The ozone is what keeps the majority of UV rays out of our atmosphere.
And then there are all of the fossil fuels being burnt, and when that happend carbon goes up into the atmosphere and creates almost a blockage so that heat can not escape out of our atmosphere. They call this the greenhouse effect because the carbon acts like a greenhouse, trapping all of this heat in with us, causing temperatures to rise, ices caps to melt and the ocean levels to rise as well.

And as for global cooling, that was just an idea that has been since disproved.

Answer 5

There is no global warming ,the theroy was based on the icebergs melting and breaking off into the sea,the truth is the iceburgs are growing and as they grow the spread out until the reach warmer water and then they break off,there is no global warming,it a bunch of bs to scare people

Answer 6

this is a stupid question theres no denying global warming you can see its effects all over the world

Answer 7

i believe... it's getting hotter evryday evrywhere... the climates are changing
