by Nic Lewis The determination of equilibrium climate sensitivity (ECS)—the long-term warming response to doubled atmospheric CO2 concentrations—remains one of the most crucial yet challenging problems in climate science. Recent exchanges in the literature have highlighted both the complexity of … Continue reading → The post Addressing misconceptions about Climate Sensitivity research: a Response to recent Criticisms appeared first on Climate Etc..

by Art Rangno How we fooled ourselves about the effectiveness of cloud seeding. The Colorado River Basin Pilot Project (CRBPP, 1970-75) is still the most ambitious, expensive randomized orographic cloud seeding project in US history. It featured an unprecedented amount … Continue reading → The post Cloud Seeding History: Looking Back at the Colorado River Basin Pilot Project appeared first on Climate Etc..

by Joe Nalven Towards improving AI architecture with a new paradigm Several years ago, I asked Bard (Google’s predecessor to Gemini) to craft an algorithm that would shift its climate change responses from catastrophism toward realism. Bard obliged. It generated … Continue reading → The post AI models and their “knowledge” of climate change appeared first on Climate Etc..

by Javier Vinos We have been fortunate to witness the largest climate event to occur on the planet since the advent of global satellite records, and possibly the largest event since the eruption of Mount Tambora in 1815. It is … Continue reading → The post The 2023 climate event revealed the greatest failure of climate science appeared first on Climate Etc..

by Chris Morris People have queried what is happening in Australia with their push for a decarbonised all renewables/ Net Zero grid since the last update in 2023. The answer is not much progress but massive amounts of money spent. … Continue reading → The post Update on Australian NetZero efforts appeared first on Climate Etc..

Right, New York Times, Scientists Do Disagree on The Polar Vortex A recent New York Times article explores claims that climate change may be worsening winter cold extremes. While some scientists argue that Arctic warming destabilizes the polar vortex, long-term data show a clear decline in extreme cold events, challenging that narrative. [...] The post Right, New York Times, Scientists Do Disagree on The Polar Vortex appeared first on Clintel.

In this analysis, Dr. Matthew Wielicki examines the EPA’s 2009 Endangerment Finding, contending that the ruling was effectively decided in advance and later justified through a structured scientific review, with far-reaching consequences for climate regulation.
