IPCC's last report says we are "unlikely" to have more than 0.5ºC more warming within the next CENTURY.

I just don't go for this alarmism stuff.

More humidity? You mean like more clouds reflecting away infrared from the sun, and cooling us? Pshaw - what sort of self-regulating system is that?

The salient effect of the industrial era is probably more desert irrigation than carbon dioxide. Just go to any irrigated dessert and see how desert like it is!

As an increasing proportion of the Earth's population live in cities, this couldn't have anything to do with Urban Heat Island Effect, could it?

Are we polluting the atmosphere? Do we have another atmosphere? Should we continue to polluting our only atmosphere?
For the trolls among us, think about it.

OHMYGODWEREALLGONNADIEAGAINAGAIN! =IF= the climate heats up, humans will have to adapt, just as we always have. It's called "evolving", and it happens when necessary. (Note that last word.) But even the IPCC doesn't buy all that alarmism, and the IPCC is formed mostly of alarmists. Interesting, isn't it?

I'm waiting for this global warming. It should benefit everyone in the northern hemisphere; longer growing seasons, warming temperatures in the Arctic for resource development, an open Arctic for shipping, probably more moisture in the form of rain / snow, etc. Nothing but goodness envisioned from this warming trend!

"Are we polluting the atmosphere? Do we have another atmosphere? Should we continue to polluting our only atmosphere? For the trolls among us, think about it."

This troll thinks CO2 is a warming gas, but not a pollutant. Agriculture production is growing more efficient worldwide due to more CO2 and more water vapor. Deserts are shrinking, not expanding. Cold kills more people than heat, though neither death for cold nor heat is much fun. And certainly, some people will suffer while in some areas people's lives will improve. Biden and Sanders will call me a liar, but their research is weak or they just like to ignore some facts.

OR not

@holdenmidfield "All of the facts on CO2 and climate run contrary to the global-warming alarmism narrative promoted by the United Nations, the Obama administration, the media, and the $360-billion-per-year “climate” industry. But they are facts nonetheless, and it is time for the press to start reporting on them honestly, the climate realist explained.

Speaking at a climate realist summit in Paris as the UN's massive COP21 conference was taking place nearby, Dr. Carter emphasized that there is no climate crisis and that many experts have even been predicting global cooling over the long term.

In an interview with The New American after his presentation, Carter explained that the CO2 added to the atmosphere in recent decades has been responsible for a tremendous greening of the planet. “That's a huge environmental benefit,” he said, adding that much of the greening had occurred along arid areas such as the Sahara Desert.

For agriculture and those who depend on it — essentially everybody who eats food — the increase in CO2 is good news, too. It has also provided huge benefits for oceans, Dr. Carter and other scientists at the Heartland Institute's “Day of Examining the Data” explained.

And contrary to the bizarre demonization of the gas of life as “carbon pollution” by the UN, Obama, and others, it is nothing of the sort.

“If you talk to most scientists, they will acknowledge that carbon dioxide is not a pollutant,” explained Dr. Carter. “Indeed, it's grotesque to call it a pollutant. It's an abuse of logic, it's an abuse of language, and it's an abuse of science.... Carbon dioxide is literally the stuff of life.”
