Unfortunately nothing is going to change, the deniers don't believe it is even happening and would refuse to even if their own home was flooded. Whether mankind is partly to blame or not does not change the fact that many will not do anything to change what they are doing, too hard and too expensive some will cry. We have large Nations such as China and India in the middle of major economic growth and both are based on the US system, meaning they will continue to dump more and more crap into the environment and over use the planets resources. Mankind will not change until he forced to change by mother nature, and the odds are it will be too late to save Millions, if not Billions, of people from starvation and death by new diseases, lack of safe drinking water, the food chain being poisoned and a wide range of other nasty scenarios brought about by the conditions such as war and more war. Sadly many species may perish for good in the process, mankind just may be among them, the planet knows how to deal with pests, especially arrogant pests. I feel for the next generations that have to survive with what our generations are going to leave them.
LOL
I feel sorry for the next generations of Americans who have ambition and will be robbed of that ambition by the other half who they will be forced to support.
Do you prefer another Ice Age? I certainly don't want 2000 meters of ice over Chicago.... Until now, added co2 has greened the planet, and not expanded deserts or increased droughts, and crop yields are high than ever.
Then again, the amount of warming over the last 50 years attribute to man is still up for debate

A newly published paper says climate change caused by humans could be responsible for as little as half the wholesale melting of sea ice in the Canadian Arctic and Greenland that has amazed and alarmed scientists.

"Unless global warming starts to accelerate at a rate far beyond what we've seen, it's going to be a long time before weather statistics change so much from the human signal that it would become clearly detectable in the presence of natural variability."

From your first link..."On the face of it, elevated CO2 boosting the foliage in dry country is good news and could assist forestry and agriculture in such areas; however there will be secondary effects that are likely to influence water availability, the carbon cycle, fire regimes and biodiversity, for example," Dr Donohue said.
"Ongoing research is required if we are to fully comprehend the potential extent and severity of such secondary effects."
From your second link......Drought is expected to increase in frequency and severity in the future as a result of climate change, mainly as a consequence of decreases in regional precipitation but also because of increasing evaporation driven by global warming. Previous assessments of historic changes in drought over the late twentieth and early twenty-first centuries indicate that this may already be happening globally. In particular, calculations of the Palmer Drought Severity Index (PDSI) show a decrease in moisture globally since the 1970s with a commensurate increase in the area in drought that is attributed, in part, to global warming.
Your third link was inadequate...Try this one...Climate Trends and Global Crop Production Since 1980
Efforts to anticipate how climate change will affect future food availability can benefit from understanding the impacts of changes to date. We found that in the cropping regions and growing seasons of most countries, with the important exception of the United States, temperature trends from 1980 to 2008 exceeded one standard deviation of historic year-to-year variability. Models that link yields of the four largest commodity crops to weather indicate that global maize and wheat production declined by 3.8 and 5.5%, respectively, relative to a counterfactual without climate trends. For soybeans and rice, winners and losers largely balanced out. Climate trends were large enough in some countries to offset a significant portion of the increases in average yields that arose from technology, carbon dioxide fertilization, and other factors.

The historical record shows that the climate system varies naturally over a wide range of time scales. In general, climate changes prior to the Industrial Revolution in the 1700s can be explained by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas (GHG) concentrations.
Recent climate changes, however, cannot be explained by natural causes alone. Research indicates that natural causes are very unlikely to explain most observed warming, especially warming since the mid-20th century. Rather, human activities can very likely explain most of that warming.
From this link..... The area of north Greenland and the Canadian archipelago, with temperature increases nearly twice as large as the Arctic average, has been warming particularly quickly.
Wallace says up to half of that increase is more likely to be due to complex atmospheric links that originate with rain and wind patterns in the South Pacific -- not warming from greenhouse gases. Unusually heavy rain in a region of the South Pacific sets up turbulence in the atmosphere that affects the whole globe, he said.
Now tell me what do you suppose is changing the wind, ocean currents and rain patterns if not a warming climate? Heat powers weather.
Global climate change alters environmental forcing mechanisms – or factors that impact ocean circulation – such as wind, precipitation, temperature, and salinity patterns. These changes in forcing mechanisms may lead to a change in ocean circulation, as well as an increase in storm activity. Ocean Circulation « Climate Change

Well, yes. If I believe it isn't happening, then if my home was flooded AGW wouldn't be the reason. That's like saying people don't believe in fire breathing dragons and would refuse to believe even if their own home burned down. Well, duh. If my home burned down it would probably be because of a gas leak or something, not because a dragon breathed fire on it.

Yes, that's true. That's one of the reasons I think liberals are such idiots for wanting to put in strict EPA regulations and carbon taxes and other such things. If we do it and our competitors don't, that will put us at an economic disadvantage. If we do it and our competitors don't, then AGW won't stop anyway. So therefore, there is no point in these liberal policies until we can verify that other industrialized nations are doing the same. Which we can't verify.

Absolute drivel. Human beings have an instinct for self preservation and necessity is the mother of invention. When the need becomes great enough, people have always responded to it. The idea that people will sit on their hands doing nothing while billions die is just absurdly stupid. There is nothing in history to indicate that, and everything in history indicates the opposite. From developing vaccines to inventing jet airplanes, humans have always responded to crises.

I feel for the next generations that have to survive while dealing with fallout from the moron policies of Democrats.
A note to my fellow "deniers": You're being unfair to those who believe that man is the scourge of the planet and is responsible for a global warming trend that will, in due time, wipe all living creatures from the face of the earth. There are those among us who have the need to see a dark cloud looming on the horizon. If such a dark cloud doesn't exist there would be no purpose for these souls. What does one do with God-given life (whoops, sorry....there is no God) if not to save a planet and protect all of mankind from himself?

Great post. Only problem is the scientifically illiterate who need to read it cannot understand it, and will instead rely on FOX and Limbaugh for their climate change information.
And lets see if and when these "secondary effects" happen if they will be negative or positive for us humans Until now, Co2 greening seems to be positive.
Scientists say that they expect lots of things to happen in the future. Until now, the last 60 years of supposedly entirely manmade global warming, there has been NO increase in severity or frequency of drought. This isn't a model simulation. This is an observation.
How about the last 30 years when we really ramped up the Co2 emissions? Nope. No change.
The models the models the models
Spin it any way you want. Fact is world food production has been steadily climbing
^^
Lots of speculation.
Greenland was several degrees celsius warmer on many occasions over the last 10,000 years
Btw, the treeline further north 8000 bp than it is today... Somehow the Polar Bears survived
We can't pretend to understand the complexity of ocean currents..... The oceans and their cycles power the weather not the atmosphere such as the Pacific Decadal Oscillation
