These posts include a brief mention of a number of news items relating to climate change. They don’t preclude treating any of these topics at more length in a separate post.
They can also serve as an open thread so that we can keep each other informed on important climate news.
Temperature increases to 2100 could be double what the models predict
That is indeed so, (see Climate Progress).
Other scientists are catching up with what James Hansen told us in 2007, namely, that according to the paleoclimate data ‘long-term’ climate sensitivity is 6°C for doubled CO2, not 3°C as assumed.
Coral reefs may survive global warming
…but will be very different, according to new research. This is not a good news story.
“It’s like having an oak tree forest replaced by a forest of scrubby young plants,” says [Professor Peter] Mumby [of QU].
For one thing they support less fish. Also please note that this research is based on a 10-year study in the Caribbean and may not apply to other areas.
India wades into tidal power
India’s first tidal power plant gets the go ahead.
Even with its potential for providing predictable and sustainable electricity generation with no visual impact, tidal power still accounts for only a fraction of a percent of the world’s total electricity generation. That is slowly changing though, with numerous tidal power plants being constructed or planned for coastlines around the world. India is the latest country to wade into the tidal power waters with the announcement of its first commercial scale tidal current power plant to be constructed in the Indian State of Gujarat.
And guess what, China and South Korea won’t be far behind.
“China’s the next big market for tidal energy,” [Atlantis CEO Timothy] Cornelius said. “It has the most natural tidal resources in the world and can be home to more than 1,000 megawatts of tidal energy.”
“Scientists: Climate Change No Longer a Theory, It’s Happening”
The raging waters In Australia and Brazil are product of global warming.
That’s according to a US ABC story via Climate progress
The pictures today from around the world of dramatic rooftop rescues from raging waters, makes it seem as though natural disasters are becoming an everyday occurrence. But they’re not all that natural; climate scientists say man-made global warming is the sudden force behind the forces of nature.
He [Derek Arndt, chief of NOAA’s Climate Monitoring Branch in the National Climate Data Center] said NOAA is tracking disasters like the floods in Brazil and Australia. “We are measuring certain types of extreme events that we would expect to see more often in a warming world, and these are indeed increasing.”
‘By 2020, world to be 2.4C warmer, India to be hardest hit’
A pity the author, who was told about the error prior to publication, didn’t pull the copy. The goons will have a field day. But for blunders it’s hard to beat Imre Salusinszky, proving once again that on climate science The Australian has no standards.
How Fast is Earth Warming?
A good question, after that last one. Tamino answers it.
Here are the graphs for five data sources:
That’s with the estimated impact of el Nino, volcanic eruptions, solar variation, and the residual annual cycle removed, leaving only the global warming trend and any remaining natural variation.
Something less than 0.2°C per decade, but significant nevertheless.
When will the record for annual warmth be broken?
With the next El Nino event in all probability. And just remember, they haven’t been cancelled.
Most of the extra energy goes into the ocean, so:
…a record depends on the behavior of the oceans, typically an El Nino or La Nina event.
Anti-science committee to oversee science
I sometimes think the American people really shot themselves in the foot at the last elections. Look who they are putting on the HOR Committee on Science and Technology. Among those featured is Paul Broun as chair of the Investigations and Oversight Subcommittee, a medical doctor who thinks that global warming is a hoax and that a cap and trade system is gonna kill people.
The Committee has a fine pedigree:
it’s a historic fixture of postwar, science-centered America—a committee originally formed after the Soviet launch of Sputnik, and one that today oversees the major research agencies: NASA, NOAA, NSF, and numerous others. For much of its history, whichever party controlled Congress, the committee was therefore run by a legislator with a sympathetic understanding of the scientific community—leaders like George Brown on the Democratic side, and Sherwood Boehlert for the Republicans.
The Chinese must be pissing themselves.
The discourse on peak oil has changed
Until recently officials and experts either remained silent or were equivocal. Now:
Increasingly, those experts and officials are saying that peak oil is near, that it is a serious danger, and that we are unprepared for it.
The IEA has switched its position since conducting a field by field survey in 2008:
This year the agency explicitly discussed peak oil for the first time and proclaimed that conventional crude most likely peaked in 2006. It continues to believe unconventional oil from the tar sands, the Arctic and deepwater fields along with natural gas liquids can make up for declining conventional oil and lead to increases in world oil production for two more decades. But it warns that this is no longer a foregone conclusion without the necessary and rather large investment required.
Two more decades of that caper and we’ll be on the road to perdition.
