Weekly Weather and Climate News Roundup

Quote of the Week: “From the household perspective, reductions in energy expenditures act like a tax cut for the Pennsylvania economy, increasing discretionary income.” Penn State report on natural gas…

CERN: "Don't interpret the CLOUD experiment results"

From the Register and Nigel Calder’s blog via bunches of people who submitted in Tips and Notes, hints of a new project, the RCC (Real Climate Collider) /sarc. CERN ‘gags’…

Earth's Climate System Is Ridiculously Complex – With Draft Link Tutorial

By WUWT regular “Just The Facts” I am often amused by claims that we understand Earth’s climate system, are able to accurately measure its behavior, eliminate all potential variables except…

Indirect Solar Forcing of Climate by Galactic Cosmic Rays: An Observational Estimate

By Dr. Roy Spencer, PhD (reprinted from his blog with permission) UPDATE (12:35 p.m. CDT 19 May 2011): revised corrections of CERES data for El Nino/La Nina effects. While I…

New study links cosmic rays to aerosols/cloud formation via solar magnetic activity modulation

From an Aarhus University press release: Scientists at Aarhus University (AU) and the National Space Institute (DTU Space) show that particles from space create cloud cover New input to the…

Update on the CERN CLOUD experiment

WUWT reader Max_B tips us off to this article and video. According to Nigel Calder’s Blog, CERN’s CLOUD experiment (testing Svensmarks’s cosmic-ray theory) shows a large enhancement of aerosol production…

Canadian Harp Seals In New England ("prediction" of cooling?)

Canadian Harp Seals may have “read” the predictions of the coming decades of stabilization of global temperatures and perhaps some cooling. Animals like the Harp Seal have experienced many millions…

The minimal solar activity in 2008–2009 and its implications for long‐term climate modeling

This is a new paper in Geophysical Research Letters by C. J. Schrijver, W. C. Livingston, T. N. Woods, and R. A. Mewaldt. WUWT readers may recognize Livingston as the…

In light of radiation fears, I offer this repost

Going bananas over radiation With all the worries over radiation leaks from Japan, and hoarding of Potassium Iodide tablets, I thought it valuable to repost a link to this story from…

Solar news: Forbush decrease in progress

The definition at Wikipedia: A Forbush decrease is a rapid decrease in the observed galactic cosmic ray intensity following a coronal mass ejection (CME). It occurs due to the magnetic…

New paper: Cosmic rays contribute 40% to global warming

From the Hindu Physicist U.R. Rao says carbon emission impact is lower than IPCC claim A key belief of climate science theology — that a reduction in carbon emissions will…

NASA gets CREAMed

No, it is not what you think…

Cosmically, Heliospherically, and Terrestrially, FYI

Last night I decided to have a look at the Space Weather Prediction Center solar charts to see how the geoplanetary magnetic index (Ap) was doing, and decided since I…

Preliminary results for the CERN CLOUD cosmic ray experiment

From Nature blog: Sunny days for CLOUD experiment An experiment designed to investigate the link between solar activity and the climate has its first results in the bag. At the…

Something to be thankful for! At last: Cosmic rays linked to rapid mid-latitude cloud changes

UPDATE: Lead author Ben Laken responds in comments below. I’ve reported several times at WUWT on the galactic cosmic ray theory proposed by  Henrik Svensmark which suggests that changes in…

Stubborn Antarctic Ozone Hole refuses to change

Maybe it is because the major catalyst isn’t CFC’s after all? See this story: Galactic Cosmic Rays May Be Responsible For The Antarctic Ozone Hole In the conclusions of the paper…

Length of day correlated to cosmic rays and sunspots

From techno-science.net This tip came in on our tip & notes page, and at first I was quite surprised because I could not see a possible mechanism for it. Then…

Climate science solar shock and awe

I saw this yesterday, but I decided to wait a day just in case it disappeared. It’s quite the surprise to see the New Scientist dedicate a story, much less…

IceCube spies unexplained pattern of cosmic rays

by Jill Sakai, University of Wisconsin Though still under construction, the IceCube Neutrino Observatory at the South Pole is already delivering scientific results — including an early finding about a…

Archibald on stellar to climate linkage

The Warning in the Stars By David Archibald If climate is not a random walk, then we can predict climate if we understand what drives it.  The energy that stops…

Solar geomagnetic index reaches unprecedented low – only "zero" could be lower – in a month when sunspots became more active

Back on December 12th 2009 I posted an article titled: Solar geomagnetic activity is at an all time low – what does this mean for climate? We then had a string…

Study shows CFCs, cosmic rays major culprits for global warming

From the University of Waterloo press release. WATERLOO, Ont. (Monday, Dec. 21, 2009) – Cosmic rays and chlorofluorocarbons (CFCs), both already implicated in depleting the Earth’s ozone layer, are also…
