Whereas the reports of the United Nations’ Intergovernmental Panel on Climate Change (IPCC) warn of a dangerous human effect on climate, NIPCC concludes the human effect is likely to be small relative to natural variability, and whatever small warming is likely to occur will produce benefits as well as costs.You may not have heard of the astroturf "NIPCC." It's the Heartland Institute's group of flacks who put out press releases meant to muddy the waters and confuse people in contrast the the real IPCC.
@DavidOAtkins So, what's the ideal climate? Has it ever changed? Before man? Can we now lock it in? Y'all seem to believe so. It's fantasy.

Global warming will disrupt food supplies, slow world economic growth and may already be causing irreversible damage to nature, according to a U.N. report due this week that will put pressure on governments to act.I will never for the life of me understand people who condemn their children, the future of the human race and the condition of all life on our planet to misery, collapse and extinction just to make an extra dolar or two in the moment.
A 29-page draft by the Intergovernmental Panel on Climate Change (IPCC) will also outline many ways to adapt to rising temperatures, more heatwaves, floods and rising seas.
"The scientific reasoning for reducing emissions and adapting to climate change is becoming far more compelling," Rajendra Pachauri, chair of the IPCC, told Reuters in Beijing.
Scientists and more than 100 governments will meet in Japan from March 25-29 to edit and approve the report. It will guide policies in the run-up to a U.N. summit in Paris in 2015 meant to decide a deal to curb rising greenhouse gas emissions.
The 29-page draft projects risks such as food and water shortages and extinctions of animals and plants. Crop yields would range from unchanged to a fall of up to 2 percent a decade, compared to a world without warming, it says.
And some natural systems may face risks of "abrupt or drastic changes" that could mean irreversible shifts, such as a runaway melt of Greenland or a drying of the Amazon rainforest.
It said there were "early warning signs that both coral reef and Arctic systems are already experiencing irreversible regime shifts". Corals are at risk in warmer seas and the Arctic region is thawing fast.
Climate change will hit growth. Warming of 2.5 degrees Celsius above pre-industrial levels could mean "global aggregate economic losses between 0.2 and 2.0 percent of income", it says.
