Climate change is not a future scenario; it is a measured present. This section follows global warming through its data: temperature records, ice and sea-level measurements, attribution studies that test whether an extreme weather event can be tied to the climate crisis, and the reports published by the IPCC and national agencies. Every story links back to where it came from — the dataset or the peer-reviewed paper — rather than to a second-hand figure.

A single greenhouse gas from China's power grid is doing outsized damage to the climate
China accounts for more than half of global emissions of sulfur hexafluoride, a gas 24,300 times more potent than carbon dioxide, and fixing the leak would cost a tiny fraction of the country's annual grid spending.

A repeat of a 1926 Miami hurricane today could be the costliest disaster in US history
Catastrophe modelers estimate a re-run of the Great Miami Hurricane would now cause around $280 billion in damage, more than Hurricane Katrina, reflecting a 23-fold increase in the region's population since 1926.
