Do you think that global warming is a serious threat, or just a scientific bluff?

Answer 1

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.
(see links below)

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Answer 2

Scientists don't bluff. Politicians do.

The extent that the current warming trend is caused by humans is hard to conclusively say. But there's absolutely no doubt that global climate change is occurring and all of our pollution can't be helping.

Answer 3

I believe there is enough evidence and scientific support to dismiss the notion that it is merely a bluff. It seems pretty evident that one cannot pump millions of tons of carbon monoxide and carbon dioxide into our atmosphere and not any effect.

I believe the possible concern that it is caused by man is real enough that steps should be taken to minimize our contribution - it's for sure that if it isn't caused by man, it certainly can't hurt to try and clean up the air that we breathe - and, if it is caused by man, the detrimental effects to future generations for not addressing the concern now will far outweigh the immediate economic benefits of ignoring the problem.

Answer 4

Look at the Ice Age, it happened, Yes global warming is very real we see and feel it's effects every day. Alaska melting Glasiers,Hotter summers, missed winters, less oxygen, because of polution, we could go on and on for all the reasons, for Global Warming, there are to many to list.

Answer 5

Yes, it is the threat that will destory our planet if we do not change our way of doing business,,,Water is at an all time threat and we are running out but no one listens.

It is a great start, Just One person to began the renewal of watching and start adjusting our life style that will better our country.

Answer 6

Definately is a serious threat. Just look around you.. I have summer plants still flowering although its end of november.. there are baby frogs still hopping about my garden and bee's, gnats and butterflies too. My hibernating tortoises usually are asleep by now but are walking around in a dazed state.. i dont know where you are but here in the southeast Uk at 11pm its warm outside and its nearly xmas!

Answer 7

U have been listening to a bunch of liars. Take CO2 they want for u to believe that it has increased 30 % it has not. I did have a job where I worked with a lot of CO2 and had to ware a monitor and it normally red 1 to 2 parts per million. it is not there because of the plants and they do photosynthesis ,now u remember. well if u lie about your Data the hole thing is a lie. The plants need the CO2 as much as u need oxygen.

Answer 8

watch the Inconvenient Truth and you will see data that will scare you...Don't let fools who can't see past their excuses fool you. It's real. We can fix it and still have a planet resembling the one we have in 50 years if we start to do things now....Don't let the fools and their ignorance kill us all for their pride.
