How colonialism spawned and continues to exacerbate the climate crisis
22 Sep 2022
We currently live in an epoch that geologists call the Holocene, which began soon after the last major ice age ended around 11,700 years ago. But for over two decades, some scientists have argued that the label is far too antiquated. In 2000, the term “Anthropocene” — ‘anthropo’ for human and ‘cene’ for new — gained prominence. It highlights how human activities dominate the Earth’s land, atmosphere, and oceans, significantly impacting its climate and natural ecosystems.

Climate ‘points of no return’ may be much closer than we thought
16 Sep 2022
In climatology, a tipping point is defined as a rise in global temperature past which a localized climate system, or "tipping element" — such as the Amazonrainforest or the Greenland ice sheet — starts to irreversibly decline. Once a tipping point has been reached, that tipping element will experience runaway effects that essentially doom it forever, even if global temperatures retreat below the tipping point.

MIT researchers propose apace bubbles to stop climate change
