New study suggests that the volcanic impact on climate may be significantly underestimated
Thick ash poured from Iceland’s Eyjafjallajökull Volcano when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image on April 17, 2010. The ash in this image…
Now it's dust storms that are caused by "climate change"
When I first saw this photo in news stories today, my first thought was “how long before somebody idiotically links this to global warming aka climate change aka climate disruption”…
Cleaner air may result in increased solar insolation and therefore warming.
This makes me wonder if the temperature dip in the 1970’s where everyone was worried about global cooling wasn’t partially driven by atmospheric aerosols. With the advent of pollution controls,…
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…
NASA'S Glory Satellite Fails To Reach Orbit
NASA reports that Glory, a satellite to monitor aerosols failed to reach orbit, apparently from a fairing that didn’t release. See update below on the massive budget overruns for this…

New paper: What Impact Would Sun Dimming Have on Earth’s Weather?
From the journal Atmospheric Science Letters press release: Could Dimming the Sun Change Teleconnections in Weather Patterns as we Know Them? Solar radiation management projects, also known as sun dimming,…
Normal Seasons of the Sun (GW Tiger)
Guest post by Ira Glickstein PhD. We had joy, we had fun, we had Seasons of the Sun. But the mountains we climbed were but whimsies of our minds. That…
Mount Merapi SO2 plume headed for Australia
Indonesia’s Mount Merapi volcano put a lot of ejecta into the air; ash, CO2, and SO2. Here’s a recent news report showing the eruption: Tracked by satellite, now the Sulfur…
Greenland Ground Zero for Global Soot Warming
People send me stuff. In my email this past week I got a cover photo of the June 2010 issue of National Geographic along with this message from Al in…
Plants Play Larger Role Than Thought in Cleaning up Air Pollution
From the National Science Foundation: “Plants clean our air to a greater extent than we had realized,” says NCAR scientist Thomas Karl, the lead author. The National Arbor Day foundation…
Where the particulates are (and aren't)
This press release from NASA has the usual FUD in it, particularly with the “health-sapping” title. But what I find most interesting is the lack of 2.5 μm particulates in…
Pollution monitoring? There's an app for that.
USC lab releases smartphone app that measures particulate air pollution ‘Visibility’ now available for download; developers hope users can help fill in the many blanks in existing air quality maps…
Another atmospheric aerosol injection plan
Via press release Palo Alto, CA—Scientists at the Carnegie Institution’s Department of Global Ecology have taken a new approach on examining a proposal to fix the warming planet. So-called geoengineering…
Climate Craziness of the Week: Global scale nanosphere nuttiness
Let’s see, what would we make those nano-disks out of? He says (see PNAS paper below): Silica-alumina ceramic hollow microspheres with diameters of 1 μm. (aka 1 micron) Do you…
Spencer on Pinatubo and climate sensitivity
Revisiting the Pinatubo Eruption as a Test of Climate Sensitivity By Roy W. Spencer, PhD. The eruption of Mt. Pinatubo in the Philippines on June 15, 1991 provided a natural…
