Temperatures were warmer than 5°C above the 1981-2010 average in September 2025 across northern Canada and into the Canadian Arctic Archipelago. The southern route of the Northwest Passage was ice-free and open for transit this past melt season.

About *a third* of global fossil fuel CO2 emissions emitted during the Industrial age have occurred in roughly the last 17 years. The previous third was emitted over a period of roughly 26 years. The first third was emitted over a period of about 131 years.

The capitalist worldview, with its emphasis on infinite growth and the commodification of nature, is the primary antagonist to the rewilding vision. This perspective frames "freedom" as the liberty to exploit and consume, and views the natural world as a collection of resources to be owned and sold.
