Corals under water

NOAA,  November 30, 2012
(Image – Pillar coral stand in the Upper Keys with blue-headed wrasse (NOAA)In compliance with a federal court ordered deadline, and consistent with existing international protections, NOAA Fisheries announced today that it is proposing Endangered Species Act (ESA) listings for 66 coral species, including 59 in the Pacific and seven in the Caribbean. This science-based proposal is more limited than the 2009 original petition that led to a settlement agreement and the court order. In order to ensure robust input, NOAA has been engaging the public since the process began three years ago. Before this proposed listing is finalized in late 2013, there will be a 90-day public comment period during which NOAA will hold 18 public meetings.

Expect more water to lap at your shores. That’s the take-home message from two studies out this week that look at the latest data on sea level rise due to climate change.

The first shows that current projections for the end of the century may seriously underestimate the rise in global sea levels. The other, on the ice sheets of Greenland and Antarctica, looks at just how much of the water stored up there has been moving into the oceans.

Both demonstrate that global warming is a real and imminent threat.

Burn it all. That is the plan in Australia’s new Energy White Paper.

Released yesterday by Resources and Energy Minister Martin Ferguson, it talks about responding to climate change while planning the opposite.

It is true that the Energy White Paper plans to diversify energy production and includes initiatives for renewable energy but this is additional to burning all of our coal and gas reserves.

New satellite images show polar ice coverage dwindling in extent and thickness.   A report from the European Space Agency‘s CryoSat-2 probe 

 Science Editor ( ice in the Arctic is disappearing at a far greater rate than previously expected, according to data from the first purpose-built satellite launched to study the thickness of the Earth’s polar caps.

Preliminary results from the European Space Agency‘s CryoSat-2 probe indicate that 900 cubic kilometres of summer sea ice has disappeared from the Arctic ocean over the past year.

Here is a novel way for responding to sealevel rise.  Just in legislate it out of existence!  This article by Bruce Henderson appeared in the News Observer on May 28.  If you look at the lobby group behind all of this, NC20, you will see that they also claim that internationally renowned researchers such as Stefan Rahmstorf  has been fabricating stories about sea level rise so that big companies such as Munich Re can raise their insurance rates!  This is nutty!

THE FIRST SCIENTIST to alert Americans to the prospect that human-caused climate change and global warming was already upon us was NASA climatologist James Hansen. In a sweltering US Senate hall during the hot, dry summer of 1988, Hansen announced “it is time to stop waffling… The evidence is pretty strong that the [human-amplified] greenhouse effect is here.”

At the time, many scientists felt his announcement to be premature. I was among them.

I was a young graduate student researching the importance of natural — rather than human-caused — variations in temperature, and I felt that the ‘signal’ of human-caused climate change had not yet emerged from the ‘noise’ of natural, long-term climate variation. As I discuss in my book,The Hockey Stick and the Climate Wars, scientists by their very nature tend to be conservative, even reticent, when it comes to discussing findings and observations that lie at the forefront of our understanding and that aren’t yet part of the ‘accepted’ body of scientific knowledge.

It’s time for conservatives to compete with liberals to devise the best, most cost-effective climate solutions.

One scorching summer doesn’t confirm that climate change is real any more than a white Christmas proves it’s a hoax. What matters is the trend—a decades-long march toward hotter and wilder weather. But with more than 26,000 heat records broken in the last 12 months and pervasive drought turning nearly half of all U.S. counties into federal disaster areas, many data-driven climate skeptics are reassessing the issue.

So far this month, 27.8 millimetres of rain has fallen in the metropolitan area.

The average for July is 169.6 millimetres.

The previous low was when recording first began in 1876 and the city received 61.5 millimetres.

WASHINGTON, July 24, 2012 /PRNewswire-USNewswire/ – For several days this month, Greenland’s surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its 2-mile-thick center, experienced some degree of melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists.

On average in the summer, about half of the surface of Greenland’s ice sheet naturally melts. At high elevations, most of that melt water quickly refreezes in place. Near the coast, some of the melt water is retained by the ice sheet and the rest is lost to the ocean. But this year the extent of ice melting at or near the surface jumped dramatically. According to satellite data, an estimated 97 percent of the ice sheet surface thawed at some point in mid-July.
