If not increasing CO2, then what IS causing the warming .... ?

The skeptics have offered a number of suggestions ...

1. The urban heat island effect distorting temperature measurements. This has been thoroughly debunked by examining records from stations far from cities and satellite measurements that map the globe rather than specific locations. It doesn't explain why the Arctic is experiencing faster rises than elsewhere, or sea temperature results.

2. Faulty or deliberate alteration of data. This is not plausible. Many nations and scientific groups have examined the data and all have concluded the planet is warming. China, Russia, Israel, Japan, India, the EU, Australia, etc all have the capability of launching satellites independently of the US so it seems unlikely that NASA and NOAA are BSing people.

3. The sun. This is the worst explanation because the changes in solar output don't correlate. When solar output was reduced in previous cycles, temperatures rose too.

4. Coming out of an ice age. The idea here is that the oceans are releasing CO2 and warming the planet as a natural consequence of a warming world after the last ice age. The problem is the oceans are a net sink of CO2 at current temperaures and CO2 isotope studies show the rise  in atmospheric concentrations to be mostly due to burning fossil fuels.

5. Cloud cover. On this issue the skeptics can't seem to decide if cloud cover increases lead to warming or cooling. There have been attempts to link warming over the past century to cloud cover but this is a circular argument since we'd expect cloud cover to be somehow correlated with warming. It seems highly unlikely that clouds can explain warming because the galactic cosmic ray concept would mean temperatures should rise and fall with solar cycles ... the continual upward trend in temperatures doesn't fit that model.

exhaust gas emitted by car will contribute to global warming ,in real life ,either we should reduce the use of car ,or we can work on hydrogen-powered car ,if many countries in the world ban the use of petrol-powered car worldwide ,and advocate the electric car or hydrogen-powered ,then the greenhouse emission worldwide will be reduced by more than a half ,s ,then we will take a giant step towards curbing the greenhouse gas emission and reducing the oil demand ,the problems is that the costs are astronomical ,I think that governments should support the development of new car and finance their programs ,it will give them a huge incentive to develop new car for worldwide market ,

Oh, look, it's 3 paid trolls in one question....

It is all the other noxious gasses coming out of vegan's intestines. Mankind evolved to eat meat, not beans. It is why we all have incisors.

You can see a direct correlation between the number of vegans and the increase in global temperature. QED.

The crackpot ideas aren't out there - they're all in here with all of these hypnotized republican goofballs

LMFAO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

republicans really are bad for democracy and the American Way.........treasonous bastards.....

Don't feed the troll

Is Darwinist/OP a paid troll?  Why would a busy guy with 2 teen kids spend so much time here?

If he's not a troll, then why does he spend so much time defending trolls who are obviously paid?

i think it is the friction created by ants and termites when they rub against each other. It creates a lot of heat
