Where The Temperature Rules The Sun

I’ve held for a long time that there is a regulatory mechanism in the tropics that keeps the earth’s temperature within very narrow bounds on average (e.g. ± 0.3°C over the 20th Century). This mechanism is the timing and amount of the daily emergence of the cumulus cloud field, and the timing and emergence of…

Robusting the chances of a megadrought in the U.S.

From CORNELL UNIVERSITY and “Hansen’s loaded dice” department comes this “robust” investigation (they use the word three times, so it must be extra robust). It is worth mentioning that without enhanced CO2 levels we enjoy today, we’ve already had a few megadroughts in the Western USA: Climate scientists study the odds of a US megadrought ITHACA,…

Calculating the Cost of Global Warming

By Andy May Hopefully, the first two posts in this series, “Do humans harm the environment” and “Population Growth and the Food Supply” have convinced the reader that man-made climate change and global warming are not an existential threat to humanity or the planet. This leaves us in a discussion of the cost of global…

New study puts the 1.5°C and 2.0°C temperature limits of the Paris Agreement into a historical climate context

The Paris Agreement adopted in December 2015 during the COP21 climate conference stipulates that the increase in the global average temperature is to be kept well below 2°C above “pre-industrial levels” and that efforts are pursued to limit the temperature increase to 1.5°C above “pre-industrial levels.” Closer inspection of the treaty text, however, reveals that…

Dueling science: One study says melting Antarctic ice sheet will flood US east coast, others say ‘uncertain’

From the “you really should get your stories straight” department. OK, here is press release #1 from the UNIVERSITY OF SOUTH FLORIDA (USF HEALTH) Melting of east Antarctic ice sheet could cripple major US cities TAMPA, Fla (December 13, 2017)- The world’s largest ice sheet may be less stable than previously thought, posing an even greater…

At #AGU17, in an attempt to prove ‘climate change creates more severe weather’, scientists resort to ‘p-hacking’

From the “If your experiment needs statistics, you ought to have done a better experiment.- Ernest Rutherford” department. From the American Meteorological Society via press release: AMS TO RELEASE REPORT EXPLAINING EXTREME EVENTS OF 2016 New research links notable weather and climate events to human influence The American Meteorological Society is releasing the strongest evidence yet that…

Hubble’s Messier celestial snow globe

From the NASA/GODDARD SPACE FLIGHT CENTER It’s beginning to look a lot like the holiday season in this NASA Hubble Space Telescope image of a blizzard of stars, which resembles a swirling snowstorm in a snow globe. The stars are residents of the globular star cluster Messier 79, or M79, located 41,000 light-years from Earth,…

What we learned from the eclipse at #AGU17

On Dec. 11, 2017, at AGU 2017, six researchers discussed initial findings based on observations of the Sun and on Earth gathered during the solar eclipse that stretched across North America on Aug. 21, 2017. Ranging from new information about the way the Sun’s atmosphere generates heat, to how the dip in solar energy affected…

NOAA’s Arctic report card released at #AGU17

Arctic shows no sign of returning to reliably frozen region of recent past decades Despite relatively cool summer temperatures, observations in 2017 continue to indicate that the Arctic environmental system has reached a ‘new normal’, characterized by long-term losses in the extent and thickness of the sea ice cover, the extent and duration of the…

ExxonMobil caves to climate activists

by Mike Bastasch Oil giant ExxonMobil has capitulated to activist shareholders and will begin issuing detailed reports on potential risks “climate change policies” pose to its business operations. “These enhancements will include energy demand sensitivities, implications of two degree Celsius scenarios, and positioning for a lower-carbon future,” Exxon wrote in a federal regulatory filing submitted Monday night.…

New mechanism for El Nino enhanced storm systems

From the INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES New mechanism to explain how El Niño influences East Asian and WN Pacific climate Western North Pacific anomalous anticyclone (WNPAC, or referred to as Philippine Sea anomalous anticyclone) is the most important anomalous circulation pattern connecting El Niño and East Asian-western North Pacific monsoon. WNPAC begins…

On the ‘IPCC climate model’

Guest essay by Dr. Antero Ollila WUWT previously published my essay on the Semi Empirical Climate Model’ on the 21st of November. In that essay I used the term “IPCC climate model” and I received some comments saying that the “IPCC has no climate model”. I understand this argument, because IPCC should not have any models according…

Study: finds a solar amplification mechanism by which solar activity & cosmic rays control climate

The HockeySchtick writes: A paper published today in the Journal of Atmospheric and Solar-Terrestrial Physics finds another potential solar amplification mechanism mediated by galactic cosmic rays [GCRs] (and distinct from Svensmark’s cosmic ray theory of climate). The author demonstrates: Solar modulation of GCR [Galactic Cosmic Rays] is translated down to the Earth climate. The mediator of solar influence…

Laughable claim: Presenting facts as ‘consensus’ bridges conservative-liberal divide over climate change

From the  UNIVERSITY OF CAMBRIDGE and the “I have a bridge to sell you in Brooklyn” department. These fools really believe the horrendously flawed 97% consensus argument, which has been refuted by other scientific papers, wins over conservatives in the climate change debate. I’m reminded of this quote from Mark Twain: Whenever you find yourself…

Malthus Redux

Guest Post by Willis Eschenbach I see that there’s another neo-Malthusian trying to convince us that global starvation and food riots are just around the corner.

Keystone is anti-hydrocarbon zealotry in microcosm

Radical environmentalists prefer dangerous, inhumane, ecologically destructive alternatives Guest essay by Paul Driessen The Nebraska Public Service Commission (NPSC) recently voted to approve the state’s segment of the 1,200-mile Keystone XL Pipeline. While that would appear to allow construction to move forward, more obstacles loom before KXL can finally bring North Dakota and Canadian crude…
