The temperature in the past has been both warmer and cooler than it is now. CO2 levels aren't the only input that determine the earth's average temperature.
So what is causing today's temperatures to rise, if not CO2? Don't forget to provide a link to evidence of whatever is causing this increase.
Another thing: each ton of CO2 added to the atmosphere contributes less to global warming than the previous ton. CO2 absorbs only a small part of the IR spectra and when it's absorbed, it's absorbed. The more serious speculative effects are that the atmosphere will heat up enough to increase H2O vapor concentrations. H2O vapor absorbs much more of the IR spectrum and, if it's concentration were to increase, could lead to the more extreme temperature predictions. But so far there's no evidence of this. So it's probably something to keep your eye on, but not lose sleep about. Despite what the warm-mongers say.
They said there hasn't been any warming for the last 15 - 17 years and might not be any for another 25 - 30 years. Also, the climate models have been wildly over predicting temperatures compared to what they then turned out to be. The sensitivity of temperature to CO2 concentrations has also been revised down in the last IPCC report. And many of the scary weather event predictions have been dropped. All in all, if global warming does occur, it should be very gradual and well within peoples abilities to adapt to it. It should also be manageable by doing things like dispersing SO2 into the atmosphere, like volcanos do.
Yes, that is what deniers have been saying not science...No warming since 98, but it is a lie.
Perhaps if the clowns like Gore and liberals who hold no credibility harped this and wanted to tax emissions, you'd have a case. That in itself convinces me it is a money grab by government and the elite knowing they are bull****ing me constantly anyhow.
~40 years ago scientists were claiming we were headed into another ice age. Wha' happened? Could those guys have been wrong? Could they be wrong today?
If we grounded jets, both private and public, would that help?
It's so darn confusing! We caused it, can't we uncause it? I need some suggestions here. I want to help so we don't all burn up!
Should we be getting the moon ready for colonizing?
for the last 17 years, the climate has niether warmed nor cooled, while CO2 has increased...
That is a denialist lie....Warming has continued. Globally, the hottest 12-month period ever recorded was from June 2009 to May 2010.
The global surface warming trend for 1997–2012 is approximately 0.11 to 0.12°C per decade....More than 90% of global warming heat goes into warming the oceans, while less than 3% goes into increasing the surface air temperature.
Signs are increasingly pointing to the formation of an El Niño in the next few months, possibly a very strong one. When combined with the long-term global warming trend, a strong El Niño would mean 2015 is very likely to become the hottest year on record by far. http://thinkprogress.org/climate/201...l-temperature/

What caused temperatures in Ice Land and Greenland to be such that they could grow wheat there in the MWP… such a feat cannot be done today?
What caused temperatures in South America to be such that maze could be grown around 800 feet higher in elevation than it can be done today?
