Human actions have driven at least 680 vertebrate species to extinction since 1500, with global vertebrate species populations dropping by 68% in around the last 50 years

One million of the estimated eight million species of plants and animals are threatened with extinction. Human actions have driven at least 680 vertebrate species to extinction since 1500, with global vertebrate species populations dropping by 68% in around the last 50 years. The abundance of wild insects has fallen by 50%. We Hug the Trees Because the Trees Have …

Common law duty of care to protect younger people against future harm from climate change

By Adam Morton, The Guardian. Eight teenagers and an octogenarian nun had sought an injunction to prevent Ley approving a proposal by Whitehaven Coal to expand the Vickery coalmine in northern New South Wales, arguing the minister had a common law duty of care to protect younger people against future harm from climate change. Justice Mordecai Bromberg found the minister had a duty of care to not …

Nature: A wasted decade of climate inaction shows us that incremental shifts that might have been sufficient at one time are no longer enough. A rapid shift with 4x the work or a third the time is necessary now. Some have stopped fossil fuel production and exploration, but not US

04 March 2020, Nature. Emissions: world has four times the work or one-third of the time: New synthesis shows what a wasted decade means for the climate pact made in Paris. Nature 579, 25-28 (2020) doi: https://doi.org/10.1038/d41586-020-00571-x, https://www.nature.com/articles/d41586-020-00571-x The past decade of political failure on climate change has cost us all dearly. It has shrunk the time left for action by two-thirds. …

Renewables are getting cheaper, but taking these fossil fuels (common resources) out of the ground and selling them is still more lucrative. We’ll need radical intervention, as big oil companies are driven by profit and won’t decarbonize by themselves.

Comment: Big oil companies are driven by profit – they won’t turn green by themselves by Brett Christophers, The Guardian. May 26, 2021 Tue 25 May 2021 551 Last week, the International Energy Agency (IEA), the world’s leading energy authority, laid bare the scale of the challenge in keeping the world on track to achieve net-zero emissions by 2050: a massive acceleration …

EV sales have increased by roughly 41 percent annually since 2015 but exponential growth will rely on policy boost

Cecilia Keating 26 May 2021 • Business Green. Also see: Give carmakers EV sales targets to accelerate uptake, government urged But exponential growth of EVs will rely on a policy boost, report claims Current rates of deployment of electric vehicles (EVs) are consistent with ‘S curve’ shaped adoption dynamics that suggest the automotive sector could ultimately reach benchmarks consistent with …

A case for transparent net-zero carbon targets and risk management: rate of emission reduction over this decade is key. Ensure temperature limits are not breached by enacting stringent near-term targets.

Nature, Published: 04 February 2021, Stephen M. Smith, Communications Earth & Environment volume 2, Article number: 24 (2021) Cite this article https://www.nature.com/articles/s43247-021-00095-w Perceived risks from carbon dioxide removal have led to calls for net zero targets to be split into separate goals for removals and emissions. A better approach is to accompany net targets with ambitious near-term action, disclose measures to achieve them and closely monitor and …

Emissions are still rising. Global fossil fuel use is similar to a decade ago.

Reuters, June 2021: https://www.reuters.com/business/environment/global-fossil-fuel-use-similar-decade-ago-energy-mix-report-says-2021-06-14/  The share of fossil fuels in the world’s total energy mix is as high as a decade ago, despite the falling cost of renewables and pressure on governments to act on climate change, a report by green energy policy network REN21 showed in its  Renewables 2021 Global Status Report Fossil fuel use has persisted amid rising …

Joeri Rogelj: Net-zero emissions targets are vague: three ways to address their limitations

Nature, 16 March 2021. To limit warming, action plans from countries and companies must be fair, rigorous and transparent. By Joeri Rogelj, Oliver Geden, Annette Cowie & Andy Reisinger Five years ago, the United Nations Paris climate agreement set a ceiling for global warming at well below 2 °C, ideally 1.5 °C relative to pre-industrial levels. World leaders also agreed to balance greenhouse-gas emissions …

Undoing Equivalence: Rethinking Carbon Accounting for Just Carbon Removal

Carbon unicorns and fossil futures. Whose emission reduction pathways is the IPCC performing?

Excerpt from: https://www.researchgate.net/profile/Wim-Carton/publication/345992520_Carbon_unicorns_and_fossil_futures_Whose_emission_reduction_pathways_is_the_IPCC_performing/links/5fb4d0b245851518fdb0926e/Carbon-unicorns-and-fossil-futures-Whose-emission-reduction-pathways-is-the-IPCC-performing.pdf The possibility of future negative emission technologies (NETs/CCS) appears to suggest that more of the same incremental policies will eventually get us there; that there is no need for drastic or economically “irrational” actions. As such it helps preserve a sense of normality against increasingly dire warnings – and observations – of an unfolding climate emergency, against …
