Francis issued his appeal, a written message for Sunday’s World Day of […]

Global annual net CO2 emissions and negative carbon emissions required to achieve the Paris climate goal of 1.5°C. This animation uses the functional form from Raupach et al., 2014 for positive emissions, adding residual, hard-to-mitigate emissions of 5 percent of the current level, and negative emissions using the ramp of a cosine function. Σ indicates the cumulative emissions 2019-2100. Graphic: Robbie Andrew

It’s getting harder and harder to limit global warming to 2°C – “It is partly this hope in future technologies that delays action”

By Robbie Andrew 23 April 2019 (Robbie Andrew) – The road to 2°C is steep; the road to 1.5°C is a cliff. While it is theoretically possible that we can keep global warming under 1.5°C above pre-industrial temperatures, that task is monumental. In fact, models struggle to generate future scenarios that keep warming below 1.5°C, but can […]

Australia greenhouse emissions set new seven-year highs on natural gas boom – “Australia is on a collision course with climate catastrophe”

By Peter Hannam 30 August 2019 (The Sydney Morning Herald) – Australia’s greenhouse gas emissions have risen to the highest annual rate since the 2012-13 financial year, driven higher by surging gas production that has made the country the world’s biggest exporter of the fossil fuel. Greenhouse gas figures [pdf] for the March quarter of 2019, […]

Can we survive extreme heat? Humans have never lived on a planet this hot, and we’re totally unprepared for what’s to come

By Jeff Goodell 27 August 2019 (Rolling Stone) – On a scorching day in downtown Phoenix, when the temperature soars to 115°F or higher, heat becomes a lethal force. Sunshine assaults you, forcing you to seek cover. The air feels solid, a hazy, ozone-soaked curtain of heat. You feel it radiating up from the parking […]

Deforestation, climate crisis could crash Amazon tree diversity – “Deforestation is no longer the only major threat to the Pan-Amazon”

By Jenny Gonzales 18 August 2019 (Mongabay) – The combined impact of ongoing deforestation and escalating climate change on the Amazon rainforest could radically transform its configuration by 2050, with the biome divided into two distinct blocks — one occupied by still significant but very seriously diminished rainforest, the other dominated by agribusiness and scattered […]

U.S. proposes easing rules on methane emissions from oil and gas production – Latest rollback “highlights the Trump administration’s complete contempt for our climate”

By Ellen Knickmeyer 29 August 2019 WASHINGTON (AP) – Oil and gas companies could face far looser oversight of emissions of potent climate-changing methane gas under a proposal expected from the Trump administration as soon as Thursday, oil industry and environmental groups said.
