Warming and Drying part 2 Natural Cycles, Climate see-saws and failed models

Natural cycles like the Madden Julian Oscillation and the El Nino Southern Oscillation cause regions of rising moist air and precipitation varying with regions of sinking cloudless dry air that…

Climate scientists realize models yield “implausibly hot forecasts of future warming”.

Climate Models: Worse Than Nothing?

Climate modeling has arguably been worse than nothing because false information has been presented as true and “consensus.” Alarmism and disruptive policy activism (forced substitution of inferior energies; challenges to…

Models In Turmoil: Underestimation Of Satellite-Based Cloud-Aerosol Interaction “Hampering Climate Change Projections”

By acting as cloud condensation nuclei (CCN), aerosols act as cloud condensation nuclei and thus can alter cloud properties and precipitation. This influences the Earth’s radiation budget and hence climate…

Climate models fail in key test region

The researchers found that when compared to observations, almost every CMIP5 model fails, no matter whether the multidecadal variability is assumed to be forced or internal. They also found institutional…

An Earth Day Reminder: “Global Warming” is Only ~50% of What Models Predict

The claim by the Biden Administration that climate change has placed us in a moment of “profound crisis” ignores the fact that the energy policy changes being promoted are based…

Current climate model simulations overestimate future sea-level rise

The current climate model simulations, which do not take ocean eddies into account, project that the ocean temperatures around Antarctica are increasing under climate change. The new high-resolution simulation shows…

$10 Million AI Grant to Improve Climate Modelling of Clouds

A Team of Scientists plans to use AI to improve climate modelling of sub-grid scale phenomena such as turbulence and clouds. But there is no reason to think an AI…

Meet The Team Shaking Up Climate Models

They have gathered some of the brightest experts from around the world to start to build a new, modern climate model. They hope to corral the vast flow of data…

Climate change could mean fewer sunny days for hot regions banking on solar power

While solar power is a leading form of renewable energy, new research suggests that changes to regional climates brought on by global warming could make areas currently considered ideal for…

Fidelity of El Niño simulation matters for predicting future climate

A new study led by University of Hawai’i at Mānoa researchers, published in the journal Nature Communications this week, revealed that correctly simulating ocean current variations hundreds of feet below…

Cold Air Rises – How Wrong Are Our Global Climate Models?

From Scitechdaily By University of California Davis May 6, 2020 The lightness of water vapor buffers climate warming in the tropics. Conventional knowledge has it that warm air rises while…
