Terminal Temperature Acceleration? On December 30, 2024, the temperature was at a record high for the time of year. Given that La Niña suppresses temperatures, the question is what is driving up the temperature.  The red dots in the above image are Copernicus ERA5 global daily mean near-surface (2m) air temperature anomalies December 13, 2022 … Read more

Sea ice [ click on images to enlarge ] The above image shows Arctic sea ice extent from November 5 to December 24, a period when Arctic sea ice is growing in extent. The red line shows 2024 sea ice extent through November 23, 2024. Dots mark Arctic sea ice extent on November 23 for … Read more

Models that analyze what is driving up the temperature all too often omit specific sources, or when included, models all too often downplay their contribution. Accordingly, policies that are promoted based on such models are all too often ineffective or even counter-productive.  Methane is all too often referred to as ‘natural gas’ originating from wetlands, … Read more

A double Blue Ocean Event could occur in 2025. Both Antarctic sea ice and Arctic sea ice could virtually disappear in 2025. A Blue Ocean Event (BOE) occurs when sea ice extent falls to 1 million km² or less, which could occur early 2025 for Antarctic sea ice and in Summer 2025 in the Northern … Read more

[ click on images to enlarge ] Temperatures remain extremely high, even though La Niña conditions may already be present, as illustrated by the above image, showing sea surface temperature anomalies (SSTA) versus 1981-2011.  The image on the right shows the Northern Hemisphere (-90°,90°) with SSTA as high as 24.8°F (13.8°C) in Hudson Bay (green … Read more

by Andrew Glikson What further evidence do the inhabitants of planet Earth need to have to convince them the liveable climate, the lungs of the Earth, is sharply deteriorating, species are dying, the mere failure of a computer chip or of a human neuron are capable of terminating civilization, that the powers that be are … Read more

The above image, created with monthly mean global temperature anomalies by LOTI Land+Ocean NASA/GISS/GISTEMP v4 data while using a 1903-1924 base, has a trend added based on Jan 2016-Aug 2024 data. The image also shows that anomalies could be 0.99°C higher when using a more genuine pre-industrial base. The image below featured in an earlier … Read more

Earth’s Energy Imbalance is now about four times as high as it was a decade ago, as illustrated by the above image, by Eliot Jacobson. As a result, feedbacks are starting to kick in with greater ferocity. Water vapor feedback One such feedback is the water vapor feedback. The temperature rise results in more evaporation, … Read more

Sunspots In a cataclysmic alignment, the next El Niño threatens to develop while sunspots are higher than expected. Sunspots are expected to reach a peak in the current cycle in July 2025. The image below (top part), adapted from NOAA, shows the observed values for the number of sunspots for cycle 25, through August 2024, … Read more

The image below shows NOAA monthly mean concentration of carbon dioxide (CO₂) recorded at Mauna Loa, Hawaii, from 2020 through July 2024. The inset shows that CO₂ was 425.55 parts per million (ppm) in July 2024, an increase of 3.72 ppm from July 2023, when CO₂ was 421.83 ppm. This 3.72 ppm growth is higher … Read more
