“Using the latest generation of models in a way that is consistent with AR6 requires both an awareness of the [hot model] problem, and easy-to-use alternatives such as those we highlight here.”
The Nature article, Climate simulations: recognize the ‘hot model’ problem (May 4, 2022) deserves more study. The article by Zeke Hausfather, Kate Marvel, Gavin A. Schmidt, John W. Nielsen-Gammon, and Mark Zelinka is subtitled : “The sixth and latest IPCC assessment weights climate models according to how well they reproduce other evidence. Now the rest of the community should do the same.’
We are climate modellers and analysts who develop, distribute and use these projections. We know scientists must treat them with great care. Users beware: a subset of the newest generation of models are ‘too hot’ and project climate warming in response to carbon dioxide emissions that might be larger than that supported by other evidence.…
Saturday (tomorrow), May 14, 2022, is World Migratory Bird Day 2022. The environmental group behind the campaign states:
Light pollution can adversely affect migratory birds on:
🔴 Behavior
🔴 Activity levels
🔴 Energy expenditure
🔴 Orientation when flying at night
🔴 Migration timing & routes
The theme this year is Dim the Lights:
…Artificial light is increasing globally by at least 2 per cent per year and it is known to adversely affect many bird species. Light pollution is a significant threat to migratory birds, causing disorientation when they fly at night, leading to collisions with buildings, perturbing their internal clocks, or interfering with their ability to undertake long-distance migrations.
Solutions to light pollution are readily available. For instance, more and more cities in the world are taking measures to dim building lights during migration phases in spring and autumn.
“Maybe instead of investigating the relatively high price [in early 2002] of gasoline, the government should check into its own regulatory and tax policies that artificially reduce supply and raise prices.”
This piece was written in first-quarter 2002 when environmental requirements were pushing reformulated gasoline prices higher, and the wellhead oil boom associated with hydraulic fractionation and horizontal drilling was a decade away.
Today, the war against oil from the Net Zero movement–now joined by the Russia/Ukraine conflict–has sent prices to historically high levels. Still, a mostly free market has wondrously overcome impediments to make a “depletable” mineral plentiful and affordable for hundreds of millions of Americans each day.
Let’s go back to the debate 20 years ago, when gasoline was sold for $1.50 per gallon (about $2.50 today)….
Crude oil prices are at a 6-month high. …
