IPCC's "Darkest Yet" Climate Report Warns of Food, Water Shortages
The Australian reports that "UN scientists are set to deliver their darkest report yet on the impacts of climate change, pointing to a future stalked by floods, drought, conflict and economic damage if carbon emissions go untamed.
A draft of their report, seen by the news organisation AFP, is part of a massive overview by the Intergovernmental Panel on Climate Change, likely to shape policies and climate talks for years to come.
Scientists and government representatives will meet in Yokohama, Japan, from tomorrow to hammer out a 29-page summary. It will be unveiled with the full report on March 31.
'We have a lot clearer picture of impacts and their consequences ... including the implications for security,' said Chris Field of the US’s Carnegie Institution, who headed the probe.
The work comes six months after the first volume in the long-awaited Fifth Assessment Report declared scientists were more certain than ever that humans caused global warming. It predicted global temperatures would rise 0.3C-4.8C this century, adding to roughly 0.7C since the Industrial Revolution. Seas will creep up by 26cm-82cm by 2100. The draft warns costs will spiral with each additional degree, although it is hard to forecast by how much."

The problem a lot of people have understanding AGW is separating the science that is settled from the unsettled predictions.
Nope.
The main problem is seeing through the fog created by the anti-AGW lobby.

They think they're being free thinkers, that the AGW people are the ones drinking the establishment cool-aid. In reality it's the other way around.

The trouble is that the rate that we are emitting carbon dioxide into the atmosphere far exceeds the rate at which plants can absorb it.
What a fool believes, he sees, no wise man has the power to reason away.
Depends on where you live.
Just as you should not confuse weather with climate, you should not confuse *regional* climate with *global* climate. The Medieval "Warm" Period refers to the temperatures in European climate. High temperatures around the North Atlantic were offset by anomalously cool temperatures elsewhere. In contrast average temperatures have been anomalously high in every region of the globe in the last decade or so.
In other words, we are experiencing *global* warming now, but had *regional* warming in the MWP.
Even withglobal warming your neck of the woods may experience instances of anomalously cool weather. Under more extreme global warming levels, where you live might even experience regional *cooling*, due to disruptions in the transfer of energy from low to high latitudes -- although that is still hypothetical at this point. At present nearly the entire planet has been experiencing higher average temperatures.

Gees, where did you get your Bio degree from? No, that not true for the majority of plants (carbon is rarely the limiting growth factor). If anything, plants become lazier as a result of high CO2 by making fewer pores for air exchange. Moreover, it's not plants but microorganisms in the ocean that produce roughly 85% of our oxygen.
Did you know that plants have mitochondria too? The way plants work is they store energy using chloroplasts during the day and expend it at night for growing. It'd be much safer for you to say that plants are carbon neutral instead of carbon negative.
Yes, they are called RCPs (Representative Concentration Pathways), what used to be the "scenarios" in older reports, and except for the dip in 2008/2009 global emissions were always above the worst case scenario. 63% of all CO2 has been emitted since scientists began to warn about AGW so there is no indication that the world will deviate from the worst case BAU path.

"... and what we've observed is the warming that was predicted. That seems to be the opposite of "totally wrong" to me."
No, it's not "the opposite of wrong"... it's just wrong. We HAVEN'T observed the warming that was predicted.
A paper in Nature last September (pdf) was a study of 117 of the most-cited CO2 climate warming models. 114 of them not only overestimated warming, the average (mean) amount they exaggerated warming (versus actual observed temperatures) was MORE THAN 100%.
And if you think that is somehow an anomaly, I assure you it isn't. The climate hasn't "warmed" in at least 16 years. AGW-proponent climate scientists publicly admit that they have no idea why.The reason is simple: their theory is fundamentally flawed.
The fact is, the theory of Catastrophic Greenhouse Gas Warming is just plain weak "science", and always has been. There is an awful lot of counter-evidence that you just haven't heard about because you have to actually look for it. It isn't spoon-fed to you by the government or the news.
Not to mention the truckloads of evidence that have continued to build concerning the compromised integrity of data, and its irresponsible handling by said climate scientists.
Add to that the publicly reported "statistics" that are so distorted one might even be justified in calling them fraudulent, like the bogus "97% consensus" claim.
And if you think "there has been no serious dispute" of these CO2-based warming claims, as many climate scientists and their supporters have tried to claim, you would be mistaken. That is a list of just some of the peer-reviewed papers that disagree.
There are mountains of such information out there, if you just but look. Do yourself and everyone else a favor, and be more skeptical.
