An important new study on climate change came out recently. I’m not talking about the Intergovernmental Panel on Climate Change (IPCC) Synthesis Report with its nonsensical headline, “Urgent climate action can secure a liveable future for all.” No, that’s just meaningless sloganeering proving yet again how far the IPCC has departed from its original mission of providing objective scientific assessments. [emphasis, links added] I’m referring instead to a new paper in the Journal of Geophysical Research-Atmospheres by a group of scientists at the U.S. National Oceanic and Atmospheric Administration (NOAA) headed by Cheng-Zhi Zou, which presents a new satellite-derived temperature...

Earth's atmosphere is rising because of climate change, a new study shows. Weather balloon measurements, taken in the Northern Hemisphere over the past 40 years, reveal that the lowest layer of Earth's atmosphere — called the troposphere — has been expanding upward at a rate of roughly 164 feet (50 meters) per decade, and climate change is the cause, according to findings published Nov.r 5 in the journal Science Advances. ... ...Climate change isn't the only human-made driver of the rising tropopause. The stratosphere — the layer above the troposphere — is also shrinking....

In one of a trio of new global warming papers in Science, Mears & Wentz (2005) address what they consider to be a large source of uncertainty in our (University of Alabama in Huntsville, "UAH") satellite estimate for global lower tropospheric ("LT") temperature trends since 1979. The satellite measurements come from the Microwave Sounding Units (MSUs) and Advanced Microwave Sounding Units (AMSUs) flying on NOAA's polar orbiting weather satellites. The UAH estimate of the globally averaged trend since 1979 to the present has been +0.09 deg. C/decade, considerably below the surface thermometer estimate that has been hovering around +0.20 deg....

For years, skeptics of global warming have used satellite and weather balloon data to argue that climate models were wrong and that global warming isn't really happening. Now, according to three new studies published in the journal Science, it turns out those conclusions based on satellite and weather balloon data were based on faulty analyses. The atmosphere is indeed warming, not cooling as the data previously showed. ... Argument evaporatesAccording to Santer, the only group to previously analyze satellite data on the troposphere -- the lowest layer in Earth's atmosphere -- was a research team headed by Roy Spencer from...

Boulder, CO, Apr. 4 (UPI) -- UPI's Climate was reminded the other day there is a broad spectrum of interpretations of the science behind global climate change. Roger Pielke Jr., a professor of environmental studies at the University of Colorado in Boulder and the author of an excellent science Web log called Prometheus, took to task a recent column on adapting to warming, saying, "You equate 'climate skeptics' with those who support adaptation. Most climate skeptics do not support adaptation because it would mean admitting that there is a problem needing to be adapted to in the first place." ......

If all goes well, a Delta II rocket will take off from Vandenberg Air Force Base, California at 3:01:59. This will be the fourth attempt.

The satellite on top of the Delta II rocket will observe Earth's climate changes and reveal processes which affect local and global air quality. NASA TV is broadcasting live web stream showing the rocket on the launch pad at Vandenburg Air Force Base. My slow dial-up ISP is getting superb clarity on RealOne Player. Launch time is 3:02 a.m.
