Dear EarthTalk: What is the best way to measure how close we are to the dreaded "point of no return" with climate change? In other words, when do we think we will have gone too far? — David Johnston, via EarthTalk.org
While we may not yet have reached the “point of no return” - when no amount of cutbacks on greenhouse gas emissions will save us from potentially catastrophic global warming - climate scientists warn we may be getting awfully close. Since the dawn of the Industrial Revolution a century ago, the average global temperature has risen some 1.6 degrees Fahrenheit. Another 0.4 degree Fahrenheit rise in temperature could set in motion unprecedented changes in global climate and a significant increase in the severity of natural disasters—and as such could represent the dreaded point of no return.
Environmental leaders point out that this doesn’t give us much time to turn the tide. Greenpeace, a leading environmental advocacy group, says we have until around 2020 to significantly cut back on greenhouse gas output around the world. “Within this time period, we will have to radically change our approach to energy production and consumption.”
“Without additional mitigation, and even with adaptation, warming by the end of the 21st century will lead to high to very high risk of severe, widespread and irreversible impacts globally,” reports the Intergovernmental Panel on Climate Change (IPCC), an international group of leading climate experts convened by the United Nations to review and assess the most recent scientific, technical and socio-economic information on global warming. Indeed, there’s no time like the present to start changing our ways.

Nonscientific American Magazine...another mag that is trash..
That is funny...
Pseudoscientific American. Too bad, used to be a good magazine.
Time magazine in the late 70s the coming Ice Age... when did the ice age happen? I think I missed it...
I think the question must be raised of how soon prosecutions for science fraud of global warming hysterics should begin?
Even mock trials would freak them out mightily.
They are going to tax the sun...
Most magazines are going to the left because of journalism is liberal... I just read an article in a model railroad magazine that made me put it back. When you see liberal views in a model railroad magazine ( published in the UK) I’m getting sick of seeing liberal crap.

1.6 degrees difference will kill us? In Florida, Tampa is 10 degrees warmer than average, so we here must be dead. Why on Friday did the Portland Sea Dogs have to cancel their home opener, BECAUSE OF SNOW? Shouldn’t it because of Sun, not snow?
My friend’s oceanfront home a million years ago would be 200 miles to the west. My brother’s house in Connecticut would be under a lake the size of Lake Superior.
Most RTD (resistive thermal device) sensors are accurate within +/- 2 degF.
Thanks. I got tired of it quite a while ago, and I’d bet I’m not the only one.
“Drink the kool aid and the planet will survive.”
When they stop living in mansions, riding about in chauffeur driven limousines, jetting about to global conferences (when they could be tele-commuting), and cease publishing on paper (strictly going electronic), I might start considering that they think that human activity has any impact on the outcome.
Kill themselves? Pshaw, that's for the commoners.
The mantra of the Left is "politicize everything".
It was there in the 1990s for awhile, then creeping political correctness was beat back for a period.
After Bush won (and won a second time) it returned.
The criticisms of Bush's alleged cocaine use, wars, alleged cronyism, dumb quotes, dumb expressions, etc. have fallen silent now that the smartest man in the room is president.
Hobbies once upon a time were an escape from the dreary concerns of "modern life". They are politicized these days and used as "teachable moments" by social(ist) justice warriors.

Were there any on Tom Jefferson’s satellites?
Global Warming is like nuclear war, people wait so long with it not happening as warned that they lose concern about it happening. At this point, it’s my honest feeling that hurricanes and tornadoes are just going to be with us for the foreseeable future, we’re going to have to respond accordingly.
