By the late 1970s we started taking sulfur out of fuels. This reduced deadly air pollution and acid rain. Unfortunately, by happenstance SO2 emissions produce reflective aerosols that cool the climate, so, in a sense, fossil fuel combustion has become more effective at warming the planet.

Humans are responsible for 100% of the *increase* of atmospheric CO2 since the pre-Industrial era. It's increased by about 50% since then.

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.

"There’s a battle underway to win the energy export market between the world’s two largest economies: The US wants the world to buy its fossil fuels, while China wants to sell the world its clean energy technologies. For now, there is a clear winner: China." - Akshat Rathi

At this rate of decline, the Annual Maximum Arctic Sea Ice Volume (in April) will be as low as what the Annual Minimum (in September) was in 1980... by the early 2040s. Think 'bout that.

Accusing people who you don’t know of being paid shills is what makes you an asshole. It’s also defamatory.

There's an entire Genre of News Articles in this country that follows the "Government won't meet it's climate targets, Report finds". They should just add it as a stand alone Category of news items in Canada.
