Modern intellectualism: “Lie to the public.”
New York Times columnist and Nobel laureate Paul Krugman on Friday suggested on HBO that scientists should get together and lie to the public about a threat of alien invasion in order to create a crisis that will force the public to agree to big government projects.
To quote him:

Climategate continues
The article describes more evidence that the tree ring data used by global warming scientists was fraudulently manipulated to suggest a warming in the past half century when the full data set showed no such thing.
Until the climate field cleans house and admits to this wrong-doing, no one is going to trust anything they say.
Forecasting hurricanes
NOAA today announced its prediction for the upcoming Atlantic Ocean hurricane season, calling for between 9 and 15 tropical storms in 2012, with 4 to 8 becoming full blown hurricanes. The NOAA release can be seen here.
To me, the range of the prediction is so wide it really doesn’t mean anything. Moreover, I wonder about the reliability of these predictions.

In a paper published today in Geophysical Research Letters, researchers studying an icecore drilled in the West Antarctic Ice Sheet have found strong evidence of the 16th century Little Ice Age in the southern hemisphere.
In a paper published today in Geophysical Research Letters, researchers studying an ice core drilled in the West Antarctic Ice Sheet have found strong evidence of the 16th century’s Little Ice Age in the southern hemisphere. From the abstract:
The temperature in the time period 1400–1800 C.E. was on average 0.52 ± 0.28°C colder than the last 100-year average. … This result is consistent with the idea that the [Little Ice Age] was a global event, probably caused by a change in solar and volcanic forcing, and was not simply a seesaw-type redistribution of heat between the hemispheres as would be predicted by some ocean-circulation hypotheses.
In an effort to emphasis human-caused global warming and eliminate any evidence of climate change caused by other factors, many global warming scientists have argued that the Little Ice Age was not a global event but merely a cooling in Europe. This data proves them wrong. The global climate has varied significantly in the recent past, and not because of human behavior. Other factors, such as fluctuations in the solar cycle, must be considered more seriously for scientists to obtain a better understanding of the Earth’s climate.

Scientists have found that a solar Grand Minimum 2800 years ago might have caused a period of cooling in Europe
Scientists have found that a solar Grand Minimum 2800 years ago might have caused a period of cooling in Europe.
The evidence for this link is at this moment slim, based upon a single data point from a lake in Germany. Nonetheless, it is further evidence that the Sun’s production of sunspots is more important to global climate than climate scientists had previously believed.
A new study has found that the glaciers of Greenland are not behaving as predicted.
The uncertainty of science: A new study has found that the glaciers of Greenland are not behaving as predicted.
In northwestern Greenland, for example, where most of the glaciers move relatively quickly and flow directly into the sea rather than ending on land, average speed jumped by 8% between 2000 and 2005 and rose another 18% from 2005 to 2010. Nevertheless, the researchers report online today in Science, the glaciers in this region showed no uniform pattern of acceleration. About one-third flowed at the same rate throughout the decade, one-fourth slowed during the interval, and about 15% slowed during the first half of the decade and then surged from 2005 to 2010.
Similarly, many of the individual glaciers in southeastern Greenland don’t follow the region’s overall trend. Although the average speeds for these glaciers increased by 28% over the decade, substantial accelerations by some glaciers were balanced by considerable slowing by others. About 43% of the glaciers in the region sped up between 2000 and 2005, but around 25% slowed down by more than 15% from 2005 to 2010.
In other words, if there is any warming, it hasn’t manifested itself in a predictable manner in the glaciers of Greenland. In fact, the data above suggests instead that if there has been any warming, it either has been far less than predicted, or has had relatively little influence on the Greenland ice sheet.

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 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.
