Below Normal Extremes…2021 Northern Hemisphere Cyclone Activity Below Normal…US Tornadoes Below Normal
The accumulated cyclone energy (ACE) is the best measure of overall tropical activity and it is below-normal for the 2021 season across the Northern Hemisphere.
Nancy Pelosi: “Mother Earth is angry”… A 9/11 non sequitur
Guest “How many non sequiturs can fit in two paragraphs?” by David Middleton Non sequitur? Definition of non sequitur 1: an inference (see INFERENCE sense 1) that does not follow from the premises (see PREMISE entry 1 sense…
Claim: Solar activity not a key cause of climate change, study shows
From the University of Edinburgh , another one-paper syndrome in the making funded by an NGO research council with a political mission to grab a headline. And, another poorly written…
Climate, Stadium Waves, and Traffic Waves
In a recent paper, Marcia Wyatt and Judith Curry posited about “Stadium Waves” and climate, suggesting that the ‘stadium-wave’ signal propagates like the cheer known as “the wave” at sporting events…
Methane estimates from the Arctic double, but there's no cause for alarm
From the University of Alaska, Fairbanks Study: Arctic seafloor methane releases double previous estimates The seafloor off the coast of Northern Siberia is releasing more than twice the amount of…
A link between the solar magnetic field and weather patterns on Earth may explain our lower than normal severe weather in 2013
From the “science is settled” department comes this new paper that points out a correlation between the Interplanetary Magnetic Field (IMF) and polar jet streams, which drive weather events on…
NSF says biosphere is breathing in CO2 more deeply
Press Release 13-139 Seasonal carbon dioxide range expanding as more is added to Earth’s atmosphere Northern Hemisphere land-based ecosystems “taking deeper breaths,” scientists find Levels of carbon dioxide in the…
Great News from Greenland
Guest essay by Dr. Patrick J. Michaels I recently returned from a trip to Greenland’s Jokabshavn Glacier, which discharges more ice than any other in the Northern Hemisphere. Our route…
Paper: 'Summer temperatures were about 10°C warmer than today, even though the concentration of atmospheric CO2 was similar'
From AAAS: From Russia with Lovely Data Climate and the atmospheric concentration of CO2 are closely linked. Brigham-Grette et al. (p. 1421, published online 9 May) present data from Lake…
Pollution in Northern Hemisphere helped cause 1980s African drought
From the University of Washington: Decades of drought in central Africa reached their worst point in the 1980s, causing Lake Chad, a shallow lake used to water crops in neighboring…
Last three years prove AGW is not responsible for tornadoes
By Joseph D’Aleo, CCM Tuesday was an active severe weather day with 29 reported tornadoes (preliminary). Enlarged But for the season thus far, we are at the bottom end of…
Mauna Loa hits 400 PPM of CO2, alarmists wail and gnash teeth, Earth survives
Source: http://www.esrl.noaa.gov/gmd/ccgg/trends/weekly.html Al Gore calls for a day of prayer and reflection, and bothering your neighbor: So please, take this day and the milestone it represents to reflect on the…
New NSF paleo research claiming Arctic was warmer fails to take major ocean circulation changes 3 million years ago into account
I covered this story earlier today, and it was presented much differently in that press release. This press release takes a different tack. IMHO, it looks like a big “ooops”…
More 'ice free Arctic' claims – we've heard it all before
From the University of Massachusetts at Amherst, something we’ve heard before. For example this claim from 2008. Gotta love the use of props to show how climate tipping points work:…
The curious case of rising CO2 and falling temperatures
Guest essay by Tony Brown Some readers might recall my recent article ‘The Long Slow Thaw?’ In this I reconstructed Central England temperature to 1538 from its current instrumental date…
Another amplification mechanism discovered by which the Sun affects Earth's climate
From The Hockey Schtick A paper published Tuesday in the Journal of Climate finds tiny variations in solar activity over 11-year solar cycles have greatly amplified effects upon climate via…
Temperature change in perspective
Guest post by Ed Hoskins The UK Met Office long term Central England Temperature record[1] has kept a continuous and consistent data set since the 1660s. It appears to be…
Future shifts in rainfall
From UC Berkeley: Rising temperature difference between hemispheres could dramatically shift rainfall patterns in tropics By Robert Sanders, Media Relations BERKELEY — One often ignored consequence of global climate change…
Study: Black carbon aerosol forcing may be an important factor affecting the snow & ice cover in the Northern Hemisphere
We’ve had several essays here at WUWT on the role of Black Carbon soot and its role in affecting surface albedo. Anyone who has ever witnessed “dirty snow” knows that…
