The statistics reveal a significant increase in global cooling degree days, which rose by 6% in 2024 compared to 2023 and by 20% above the long-term average from the first two decades of the century. This metric, which measures the need for cooling based on temperature exceedance of a 21°C baseline, directly correlates with the rising demand for air conditioning. In 2022, air conditioning accounted for 7% of the world’s electricity demand. The number of air conditioning units worldwide, which stood at less than 2 billion in 2016, is projected to nearly triple to 6 billion by 2050. This growth, while indicative of rising household incomes, poses a challenge to energy grids. In some U.S. regions, air conditioners can account for over 70% of residential energy demand during peak times. Innovations in cooling technology, such as energy storage systems and desiccant cooling, along with advancements in heat exchanger design, are crucial to meeting this demand efficiently.

Feb 9 Studies of earth’s geological past reveal the crooked climate campaign led by the United Nations. There’s not enough carbon dioxide in the world to control or change climate. It’s a trace gas 4 molecules in 10,000, produced by nature & essential in plant photosynthesis.

@NASA
The most important graph in the world is going up again.
The four-year average Earth’s Energy Imbalance is record high at +1.41 W/m².
Even with a record hot January 2025 of +1.75°C, the monthly (climatology corrected) Earth’s Energy Imbalance was +2.5 W/m²!

Mar 30 Did you know that 2/3 of all energy we use ends up as waste heat because of how inefficient our energy system is?
Yet we pay for 100% of the energy inputs.
Here’s the US as an example.

17h We have the largest energy storage system on the planet right under our feet. Time to tap into it.
“… could cut hundreds of gigawatts of peak demand and tens of billions of dollars in grid costs over the coming decades.”

Feb 6 NASA CERES Earth’s Energy Imbalance and Accelerated Global Warming, James Hansen his new paper
Earth’s Energy Imbalance increased by +1.0 W/m² over the past 20 years. Hansen estimates an increase in absorbed sunlight due to shipping emissions reductions of +0.5 W/m²!

“global glaciers are losing ice at an alarming rate, averaging 270 billion tonnes annually from 2000 to 2023,”
