Spencer on the Lacis-NASA GISS CO2 paper
Does CO2 Drive the Earth’s Climate System? Comments on the Latest NASA GISS Paper by Dr. Roy Spencer There was a very clever paper published in Science this…
Climate Model Bias 5: Storminess
By Andy May In part 4 the impact of convection and atmospheric circulation on climate was discussed. When circulation patterns change, they change the speed and efficiency of the transport…
Climate Model Bias 3: Solar Input
By Andy May In part 2 we discussed the IPCC hypothesis of climate change that assumes humans and our greenhouse gas emissions and land use choices are the climate change…
Climate Model Bias 2: Modeling Greenhouse Gases
By Andy May Since the late 19th century, with the work by Svante Arrhenius, climate models have been used to estimate the amount of global warming due to human greenhouse…
Long Term Climate Sensitivity After All Feedback Has Acted
The problems encountered by scientists trying to put a number on Equilibrium Climate Sensitivity (ECS) for CO2x2 are almost insurmountable because of this complexity and estimates, consequently, vary greatly.
Dr. Jim Advises Panic
Guest Post by Willis Eschenbach I see that my favorite serially failed climate doomcaster, Dr. James Hansen, is at it again. Accompanied by his usual Greek chorus of co-sycophants, he’s…
Atmospheric water vapor (TPW) and climate change
By Andy May Christian Freuer has translated this post into German here. In the latest IPCC major report, AR6, they report: “a best estimate of equilibrium climate sensitivity of 3°C,…
The Climate Feedback Debate
Unless somebody has a better explanation, it seems likely that the IPCC needed to keep the 3.0°C ECS for political reasons and simply altered the various feedback parameters to suit.
Talk on Climate Shifts for the Creative Society
By Andy May The Creative Society ask to interview me on the 20th century climate shifts that Dr. Javier Vinós and I discussed in Part IV of our series of…
A Critical Assessment of Extreme Events Trends in Times of Global Warming
None of these response indicators show a clear positive trend of extreme events. In conclusion on the basis of observational data, the climate crisis that, according to many sources, we…
Refutation of the Forgotten-Sunshine Theory
The theory that feedback law rules out high ECS values is like the theory that there’s no greenhouse effect: although its conclusion is attractive, the theory itself is clearly wrong.
The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (III). Meridional transport
Contrary to what could be naively expected, the Earth is warmest just after the June’s solstice, when it is farthest from the sun, and coldest just after the December’s solstice,…
How Climatologists Forgot the Sun Was Shining: Your Questions Answered
Their error was so large that, after correction, the near-certainty of future global warming large enough to be catastrophic vanishes, and the tawdry notion of “climate emergency” with it.
The new Pause lengthens: now 7 years 6 months
On the UAH satellite monthly global mean lower-troposphere temperature dataset, seven and a half years have passed since there was any trend in global warming at all.
No Statistically-Significant Global Warming For 9 Years 3 Months
The New Pause lengthens and lengthens. On the UAH dataset, the most reliable of them all, there has been no global warming at all for fully seven years:
Ice Ages, Feedback Diagrams, and Climate Triggers
As well defined turning points in response and a limit-cycle of operation are long established characteristics of relay control systems, I submit that Earth’s climate regulation is non-linear in much…
The New Pause lengthens by a hefty three months
On the UAH data, there has been no global warming at all for very nearly seven years since January 2015 of 2015. The New Pause has lengthened by three months,…
CO2 and Temperature
By Andy May I had a very interesting online discussion about CO2 and temperature with Tinus Pulles, a retired Dutch environmental scientist. To read the whole discussion, go to the…
Temperature Regulated Cooling Dominates Warming and Why the Earth Stopped Cooling At 15°C
Guest Post by Wim Röst Abstract It is said that the Earth’s surface temperature variations are controlled by [human-induced] greenhouse gases1. This is not the case. When cooling systems dominate,…
The Old Farmer’s Almanac Seasonal Forecasts
By Andy May The Old Farmer’s Almanac has been making yearly long-term weather forecasts for 230 years. We pay attention to them because they are normally 80% accurate. They did…
Boris, here’s why net-zero emissions by 2050 just aren’t worth it
Net-zero just isn’t worth it. Let us do the math that no government seems to have done. It is not very difficult – but the results are astonishing.
Are Climate Feedbacks Strongly Non-Linear?
Is it possible that the Earth’s system is strongly buffered with strong positive ice and dust feedbacks prevailing at colder temperatures, and strong negative convection/evaporation feedbacks prevailing in warmer times?
Why Models Can’t Predict Temperature: A History Of Failure
The bottom line is that climatology is simply wrong about the magnitude of future global warming. No government should pay the slightest attention to anything it says.
