I don't know what everyone's talking about!
Obviously Megan Fox is causing global warming. She is so hot!

@JonThm Correct.

you have some great stuff here

Green plants have metabolised all mankind's additional carbon dioxide. To form new life. No weather effect possible. That is a nuclear lie.

Climate change is fiction from nuclear power

1 Nobody's trying to predict the weather in the long term. That's nearly impossible. What is easy to predict is the climate. Wait, let me try. I predict there will be snow in New York in January. I predict there will be several hurricanes over the Atlantic between July and October 2015. I predict that if you plant olives in southern Spain, they will likely thrive over the next 20 years. I predict there will be at least 10 days over 100F in Houston next summer and none in Anchorage.

It depends on which time scale you want to consider. CO2 stays much longer in the atmosphere than methane. So, on a short time scale (about 20 years), methane traps about 72 times more heat than CO2. On medium time scales relevant to us (100 years), it has 25 times more warming potential than CO2 and on longer timescales the number goes down. There are some interesting tables on wikipedia. Search "global warming potential".

Would it be inconveivable that CO2 could both be a cause and a consequence? In my understanding, climate scientists have known for many, many years that warming in the past has caused CO2 to rise by outgassing from the oceans as well as by other mechanisms. For example, the huge temperature swings from glaciations to interglacials can't be explained by the weak solar forcing from the Milankovic cycles in Earth's orbit alone. So, CO2 works as an amplifying feedback: +CO2 -> +Tº -> +CO2

@voteclimateinfo wrong it was warmer during the MVP and co2 is an effect of temp not a driver
The primary source of energy keeping our world warm enough for anything to live here is our star. Our distance from that star varies enough to change the amount of energy our earth can catch. Additionally, the suns output varies through time. That's why we see changes in temp on the other planets too.

@356pla True! Ice ages are cyclical with orbit variations, melting permafrost releases CO2 creating a warming periods. However, CO2 concentration is now higher than its been in the past 650,000 years and shooting up. This is causing an unnatural, unprecedented and rapid (in earth terms) temp increase. It's happening faster than species can evolve and will disrupt human civilization that's arisen based on a temperate climate. Messing with our atmosphere in this way is a very risky experiment.

This tuesday's election results will have a huge impact on my survival chances during the coming decades.
Yet I have no right to vote in a country that is not mine.
I can only stand by and watch. Fearfully.
Please, friends in the USA, hear my voice.
I beg you not to vote for any politician that has expressed doubt about the science of global warming.

@arneperschel The good news was that prop 23, the oil companies attempt to block California global warming laws was overwhelmingly defeated. Where CA goes, other states may follow. I can't imagine that it's a very good long-term strategy for Republicans to be anti-science -- particularly if we make this a key issue in 2012.
