Cryosat has released its first seasonal variation map, tracking the growth of the Arctic icecap for the winter of 2010-2011.
Cryosat has released its first seasonal variation map, tracking the growth of the Arctic icecap for the winter of 2010-2011.
The video at the link is quite interesting to watch. Note however that the press information says nothing about whether the icecap was larger or smaller than expected, something that probably is not surprising. It will probably take decades of further work to get the true context of these results.
The Great Lakes are not drying up, as predicted by global warming advocates.
Wrong again: The Great Lakes are not drying up, as predicted by global warming advocates.
The global warming advocate who invented the concept of “Gaia” now admits he was wrong about global warming.

“The problem is we don’t know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books – mine included – because it looked clear-cut, but it hasn’t happened,” Lovelock said. “The climate is doing its usual tricks. There’s nothing much really happening yet. We were supposed to be halfway toward a frying world now,” he said.
“The world has not warmed up very much since the millennium. Twelve years is a reasonable time… it (the temperature) has stayed almost constant, whereas it should have been rising — carbon dioxide is rising, no question about that,” he added.
It’s not just a good idea, it’s the law!
Mexico has passed its own very strict climate change law.
The new law contains many sweeping provisions to mitigate climate change, including a mandate to reduce emissions of carbon dioxide by 30% below business-as-usual levels by 2020, and by 50% below 2000 levels by 2050. Furthermore, it stipulates that 35% of the country’s energy should come from renewable sources by 2024, and requires mandatory emissions reporting by the country’s largest polluters.

Satellite photos have revealed that there are twice as many emperor penguins in Antarctica than scientists had predicted.
The uncertainty of science: Satellite photos have revealed that there are twice as many emperor penguins in Antarctica than scientists had predicted.
Not surprising in this era of spin-generated science, every article I’ve seen on this story (here’s another) has felt obliged to say how this news means the poor penguins will start off stronger when global warming arrives to decimate their population. However, wasn’t global warming already happening? And wasn’t that warming supposed to have decimated their population already?
The truth is we really don’t know. This new data could actually mean that emperor penguins like global warming. It could suggest that global warming hasn’t started yet. It could even be evidence that the climate isn’t warming at all.
But no, let’s just spin it in one direction: global warming is happening, and it will kill penguins. No matter how many penguins we find.
Europe’s primary Earth-observation satellite has gone silent.
Europe’s primary Earth-observation satellite, Envisat, has gone silent.
Launched in 2002, the satellite is billed as the most sophisticated environmental monitor in orbit, with ten instruments providing streams of valuable data on everything from ozone, clouds and greenhouse gases to land-use trends and sea-surface temperatures — data that have figured in more than 2,000 scientific publications, ESA says. Over the years, Envisat has also offered a unique vantage point on major environmental disasters such as the December 2004 earthquake and tsunami in southeast Asia and the Deepwater Horizon oil spill in the Gulf of Mexico in 2010. Now, scientists fear that the satellite’s decade-long run has come to an abrupt end.
Problems began on 8 April when the satellite’s signal cut out as it was passing over a ground station in Sweden. ESA has been working with a team of scientists and engineers to diagnose the problem and to re-establish contact, but the outlook remains unclear.
A new study suggests that building wind turbines is a far greater problem to birds than actually operating them.
Good news for wind power: A new study suggests that building wind turbines is a far greater problem to birds than actually operating them.
The uncertainty of science, however: the study also showed a wide range of effects, depending on bird species.
Mars: dry with only periodic short bursts of wetness.
Mars: dry with only periodic short bursts of wetness.
Though this Science article outlines well the present “consensus” for Mars’s past climate, it also tries to make it sound like the planetary science community had once believed that Mars was once ocean-covered like the Earth and now has abandoned that consensus. To this I say bunk. Though many respected planetary scientists have looked for and found evidence for a past ocean on Mars, this possibility has always been controversial. From my readings most planetary scientists have always believed that Mars has generally been dry, interspersed with short periods when there is flowing liquid water on its surface. Even the advocates of the Martian ocean never proposed an Earthlike ocean, but a somewhat shallow and short-lived phenomenon.
Fifty top NASA experts, including astronauts, scientists, and engineers, have issued a letter demanding that NASA stop making global warming claims in press releases and websites.
A new consensus: Fifty top NASA experts, including astronauts, scientists, and engineers, have issued a letter demanding that NASA stop making global warming claims in press releases and websites.
We, the undersigned, respectfully request that NASA and the Goddard Institute for Space Studies (GISS) refrain from including unproven remarks in public releases and websites. We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data. With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.
The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements.
The individuals who signed this letter comprise a who’s-who from NASA’s science and space exploration work over the past fifty years. Their willingness to sign such a letter cannot be dismissed lightly.
