Hmmm?
studies conclude that natural cycles and solar activity are the chief drivers.

Do you guys not read the Holy Bible? If
so, you know that 'global warming' is just
God - trying to get us human beings'
attention.

It doesn't matter if it's got a title or
not - it is from God's Hand.

My two cents of advice says we best start
listening - and repenting.

So he is trying to claim water vapor as a DRIVER of AGW, which it isn't. It is a RESPONSE to the driving of climate from the main inputs, solar cycle, aerosols and GHGs. As these factors change the temperature, water vapor increases and thus 'amplifies' the forcings. But it doesn't DRIVE any changes. These sort of misstatements and out of context posting are part and parcel of the DIVERSIONARY tactics of the denialists.

Deny this you fear mongers!

Science DOES NOT say and in 28 years has never said climate change IS or WILL be a crisis only could be and they won't say their "possible" crisis is as inevitable as they love to say comet hits are. But unstoppable warming IS a comet hit!
Science ONLY agrees:
"Climate change is real and is happening and "could" cause, might cause, possibly cause......unstoppable warming. Not one IPCC warning isn't swimming in "maybes" and "could bes". Help my house could be on fire maybe?
You can't have a little unstoppable warming crisis outside of Harry Potter movies.

I don't remember if I called you un-scientific and stupid, but that'll work.

Science papers and newspapers are two different things, illegitimate child. I've read both and the science says greenhouse gases.

Where are the studies backing natural cycles and water vapor as causes for the heating of the past century and a half?

Neither will eradicating tobacco cure all cancers. CO2 is not "THE" cause of climate change. It is only one of the causes. Unfortunately, excess CO2 is the result of burning fossil fuels and is a known greenhouse gas.

“Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes. I personally resent it bitterly.”

CO2 has preceded warming before.

http://www.google.com/url...

Most previous warming episodes have been due to other forcings, resulting in the release of CO2 because of the warming. Since humans are the main forcing now, you can expect to see more greenhouse gases released naturally because of us. Yes, many things cause climate change; now add humans to the list.

It's funny that the only way that you know that the Earth has warmed in the past is through the work of the very scientists who you say now have it all wrong. IOW, you're believing what you want to believe and rejecting what you don't like.

The abstract of the study in news:

[1] Satellite observations reveal a greening of the globe over recent decades. The role in this greening of the ‘CO2 fertilization’ effect – the enhancement of photosynthesis due to rising CO2 levels – is yet to be established. The direct CO2 effect on vegetation should be most clearly expressed in warm, arid environments where water is the dominant limit to vegetation growth. Using gas exchange theory, we predict that the 14% increase in atmospheric CO2 (1982–2010) led to a 5 to 10% increase in green foliage cover in warm, arid environments. Satellite observations, analysed to remove the effect of variations in rainfall, show that cover across these environments has increased by 11%. Our results confirm that the anticipated CO2 fertilization effect is occurring alongside ongoing anthropogenic perturbations to the carbon cycle and that the fertilisation effect is now a significant land surface process.

Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide “fertilization effect” has, indeed, caused a gradual greening from 1982 to 2010.

Focusing on the southwestern corner of North America, Australia’s outback, the Middle East, and some parts of Africa, Randall Donohue of the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Canberra, Australia and his colleagues developed and applied a mathematical model to predict the extent of the carbon-dioxide (CO2) fertilization effect. They then tested this prediction by studying satellite imagery and teasing out the influence of carbon dioxide on greening from other factors such as precipitation, air temperature, the amount of light, and land-use changes.

The team’s model predicted that foliage would increase by some 5 to 10 percent given the 14 percent increase in atmospheric CO2 concentration during the study period. The satellite data agreed, showing an 11 percent increase in foliage after adjusting the data for precipitation, yielding “strong support for our hypothesis,” the team reports.

“Up until this point, they’ve linked the greening to fairly obvious climatic variables, such as a rise in temperature where it is normally cold or a rise in rainfall where it is normally dry. Lots of those papers speculated about the CO2 effect, but it has been very difficult to prove.”

The team looked for signs of CO2 fertilization in arid areas, Donohue said, because “satellites are very good at detecting changes in total leaf cover, and it is in warm, dry environments that the CO2 effect is expected to most influence leaf cover.” Leaf cover is the clue, he added, because “a leaf can extract more carbon from the air during photosynthesis, or lose less water to the air during photosynthesis, or both, due to elevated CO2.” That is the CO2 fertilization effect.

But leaf cover in warm, wet places like tropical rainforests is already about as extensive as it can get and is unlikely to increase with higher CO2 concentrations. In warm, dry places, on the other hand, leaf cover is less complete, so plants there will make more leaves if they have enough water to do so.“If elevated CO2 causes the water use of individual leaves to drop, plants will respond by increasing their total numbers of leaves, and this should be measurable from satellite,” Donohue explained.

To tease out the actual CO2 fertilization effect from other environmental factors in these regions, the researchers first averaged the greenness of each location across 3-year periods to account for changes in soil wetness and then grouped that greenness data from the different locations according to their amounts of precipitation. The team then identified the maximum amount of foliage each group could attain for a given precipitation, and tracked variations in maximum foliage over the course of 20 years. This allowed the scientists to remove the influence of precipitation and other climatic variations and recognize the long-term greening trend.

In addition to greening dry regions, the CO2 fertilization effect could switch the types of vegetation that dominate in those regions.“Trees are re-invading grass lands, and this could quite possibly be related to the CO2 effect,” Donohue said.“Long lived woody plants are deep rooted and are likely to benefit more than grasses from an increase in CO2.”

“The effect of higher carbon dioxide levels on plant function is an important process that needs greater consideration,” said Donohue.“Even if nothing else in the climate changes as global CO2 levels rise, we will still see significant environmental changes because of the CO2 fertilization effect.”

Renewables have seen such dramatic price falls in the past few years that they are threatening to upset the world as we know it and usher in an almost unprecedented boom in the spread of cheap, clean, home-produced energy.

Solar will be the cheapest form of power in many countries within just a few years. In places such as California and Italy it has already reached so-called "grid parity". Onshore wind, on a piece of land not constrained by years of planning delays, is already the cheapest form of energy on earth. These are not wild claims – those are figures from General Electric, Citibank and others.
