As the climate data for 2025 continues to be released, it's time to update various data visualisations.

First - the global climate stripes for 1850-2025. A third darkest red stripe is added.

The last 11 years have been the warmest 11 years on record. A sequence that is unlikely to be broken soon.

China deploys new 1 MW Wind Turbine that can generate energy at $0.02 a KwH and is far more reliable because it operates at higher altitude.

Meanwhile moronic USA bans clean energy and has average electricity costs approaching $0.20 a KwH.

“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”
Uruguay’s Renewable Charge: A Small Nation, A Big Lesson For The World
Uruguay built a power grid that runs 99% on renewables—at half the cost of fossil fuels. Here’s how its bold energy overhaul became a global model.
