People scream outside the United Nation’s Intergovernmental Panel on Climate Change in Stockholm to demand immediate political action on the climate on September 27, 2013

1. It’s happening and we’re doing it: This report concludes that the earth is unequivocally changing, and the evidence is clear that humans have a large role in how it has changed over the last 60 years.

2. 95-100 percent certain: Each of the IPCC’s last five big reports found that climate science has gotten increasingly certain that the planet is warming, and humans are the main cause. Scientists have a 95-100 percent certainty (“extremely likely”) that humans are causing temperatures to rise. Directly from the report: “It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together.” The report in 2001 was 66 percent certain, and the 2007 report was 90 percent certain. Scientific conclusions that cigarettes are deadly and that the universe is about 13.8 billion years old have similar levels of certainty.

3. Warmest 30 years: The globe has already warmed 0.85°C from 1880 to 2012. 0.6°C of that warming happened since 1950, and “1983–2012 was likely the warmest 30-year period of the last 1400 years.”

4. Pause? What pause?: The report itself does not mention the word “pause,” but does describe the long term and short term increase in temperature. Since 1880, the nine warmest years have happened since 1998. 1998 was a very warm year partially because a warm ocean caused by El Nino did not take up as much heat as normal, which made the atmosphere warmer. Without 1998?s anomaly, there is no “slowdown,” “plateau,” “pause,” or “speedbump.”

2. # 15. - Blistering pace...

15. Blistering pace: To put the report’s findings in perspective, Stanford scientists Noah Diffenbaugh and Chris Field found that the current pace of warming is happening 10 times faster than any time over the last 65 million years

5. Thanks for the thread xchrom

This is important news and not something the deniers will be able to deny... ok, rationally deny.

6. Anyone who doesn't think climate change is really happening needs to watch "Chasing Ice."

http://www.chasingice.com/

Chasing Ice is a 2012 documentary film about the efforts of photographer James Balog and his Extreme Ice Survey to publicize the effects of climate change, directed by Jeff Orlowski. It was released in the United States on November 16, 2012.

He has stunning, horrifying visual evidence that the arctic is melting. And it's melting fast. This film is must see video! The photography is stunning, the message critical. He was a climate change denier & now recognizes it as the number one issue facing our species today.

10. Definitely a stunning, and shocking, documentary. nt

9. I posted an interactive map showing how regions of the earth will likely be affected.

It is from Le Monde.

The Midwest's agriculture is anticipated to suffer. The Mississippi Delta also. There are other repercussions for the US. If that map is accurate or even close, I'd be especially worried if I were a farmer in, say Iowa.

...to sucker people about climate change. As usual.
