New satellite data covering the period from 2000 to 2011 now shows that the atmosphere traps far less heat than predicted by every global warming climate model.
The uncertainty of science: New satellite data covering the period from 2000 to 2011 now shows that the atmosphere traps far less heat than predicted by every global warming climate model.
The models had predicted that the increase in CO2 — which is insufficient on its own to cause a greenhouse effect — would cause feedbacks with water (the atmosphere’s real greenhouse gas) that would increase the amount of atmospheric humidity which would thus trap heat in the atmosphere and raise the global temperature. The new data instead shows the opposite. The atmosphere is not trapping any heat. The greenhouse effect is not occurring as predicted.
Many in the astronomy community do not agree with the recent conclusions of one astronomer that Comet ISON is likely a dud.

The arguments from both sides are quite interesting. Stay tuned. We will find out in only a few more months.
According to the observations of one Italian astronomer, it appears that Comet ISON will not be the “Comet of the Century,” as hoped.

This fits with other recent reports, all of which suggested that the comet is not brightening as it should.
A supernova has exploded in the galaxy M74, only 30 million light years away.
A supernova has exploded in the galaxy M74, only 30 million light years away.
This is one of the closest supernovae in recent years. Though it is still brightening and has reached 12th magnitude, it is not expected to brighten to naked eye visibility (about 6th magnitude). Astronomers however have spotted the progenitor star in archival Hubble images, which they have identified as a M-type red supergiant that was also particularly bright in the infrared.

A Norwegian town, sunless for five months of the year, is building a giant array of mirrors to light up its town square.
A Norwegian town, sunless for five months of the year, is building a giant array of mirrors to light up its town square.
Three mirrors with a total surface area of about 538 square feet will sit at an angle to redirect winter sun down into the town, lighting up over 2150 square feet of concentrated space in the town square. A similar idea exists in the Italian village of Viganella, which has used brushed steel to reflect light since 2006.

Observations of Comet ISON have detected strong carbon dioxide emissions escaping from the comet.
Call Al Gore! Observations of Comet ISON have detected strong carbon dioxide emissions escaping from the comet.
Images captured June 13 with Spitzer’s Infrared Array Camera indicate carbon dioxide is slowly and steadily “fizzing” away from the so-called “soda-pop comet,” along with dust, in a tail about 186,400 miles (300,000 kilometers) long. “We estimate ISON is emitting about 2.2 million pounds (1 million kilograms) of what is most likely carbon dioxide gas and about 120 million pounds (54.4 million kilograms) of dust every day,” said Carey Lisse, leader of NASA’s Comet ISON Observation Campaign and a senior research scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. “Previous observations made by NASA’s Hubble Space Telescope and the Swift Gamma-Ray Burst Mission and Deep Impact spacecraft gave us only upper limits for any gas emission from ISON. Thanks to Spitzer, we now know for sure the comet’s distant activity has been powered by gas.”
