How much of global warming is human civilization responsible for?
The last Ice age end 18,000 years ago at which point global warming began. This is before human civilization. So man didn’t start global warming but is contributing to the situation. I find that the warming rate is still a point of discussion but the total is around 2 degrees F every ten years. What part of the 2 deg F is caused by human civilization?
Leon – You need to do some reading and get the facts. The ice started melting before man built a city.
Larry B – "Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100." http://en.wikipedia.org/wiki/Global_warming
So we are talking about .2 – 1.1 deg F over 10 years from your source, but I have seen some at 2.5 deg F per 10 years.
Jeff P – What part of you speech is the answer to the question?
Hypofocus – I’m asking a question in order to make informed decisions. I’m not one of the sheep just getting in line!
Bob – Thanks for the graph, it paints a good picture.
When is global warming going to start harming the earth?
We all know about global warming, and how it is causing the ice to melt, the earth getting polluted, and all the other things happening to the earth, like rising temperatures and such, but when is it really going to come into effect? When will we experience everything? In 5 or 10 years? In 100 years? In 1000 years? in 10 000 years?
Is there a definite answer? Or will the earth just suddenly ‘die out’ one day?
How much do you think building a green house will cost 10 years from now, in comparison to the prices now?
Currently, most green building materials are pretty expensive, at least in the US.
Say that it’d cost around 0,000-0,000 to build a 3,000 square foot completely green house now.
How much would it cost 10 years from now?
What green materials do you think will be mass produced?
What do the proponents of global warming consider normal climate change?
The climate has changed for billions of years.
It’s been much hotter and much colder.
The temperature has gone up and down slower and faster.
There has been much more and much less CO2 in the atmosphere.
The CO2 has increased and decreased at slower and faster rates as well before humans exsisted.
Also other planets in the solar system are changing at the same rate as earth.
Why is it any different now?
How can this be attributed to humans when this has all happend even before Humans were here?
It seems that the so called environ"MENTAL" crowd should be behind global warming, if it’s going to be as bad as they say. All of the catastrophy that they claim will happen
will only result in a reduction of population, a key component in there argument to stop global warming.
And if the debate is over, do the proponents of global warming/Climate change, understand they have lost?
So the whats normal change?
The Younger Dryas even changed by 10 to 18 degrees in approximately 10 years and then changed back.
But mankind couldn’t have had any effect at the time.
And patrick is right, scientists know nothing about Climate change so how can it be said the debate is over?
