Today, we are close to the critical moment when conventional economic growth becomes impossible on a finite planet, constrained by two parallel factors: resource depletion and pollution. Tthe depletion of fossil fuels and other mineral commodities is placing heavy constraints on both industrial and agricultural production. We are not running out of anything yet, but the cost of extraction is increasing, just as the damage that extraction causes to the ecosystem. On the other side, pollution is appearing in more than one form. Chemical pollution is growing in terms of heavy metals, endocrine-disruptors, and other poisoning substances, while climate change can be seen as another form of pollution generated by the excess of CO2 in the atmosphere.

A deal is welcome after talks nearly collapsed but the final agreement contains small steps rather than leaps

The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.

CO2 in air hit new high last year, with scientists concerned natural land and ocean carbon sinks are weakening

The planet is nearing dangerous limits. Yet progress on clean energy shows what’s possible. With political will, cooperation can still avert the worst of the climate crisis

The Production Gap Report finds that 10 years after the Paris Agreement, governments plan to produce more than double the volume of fossil fuels in 2030 than would be consistent with limiting global warming to 1.5°C, steering the world further from the Paris goals than the last such assessment in 2023.

António Guterres says ‘sun is rising on a clean energy age’ as 90% of renewable power projects cheaper than fossil fuels

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend

Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global

Dans le cadre de la transition énergétique, l’aviation se tourne vers des e-fuels nécessitant des volumes importants d’électricité bas carbone pour être produits. Or, cette électricité est bien moins taxée que l’électricité destinée à des besoins « primaires », tels que le chauffage ou l'éclairage, comme le détaille mon étude publiée dans Climate Policy(1).

The world’s addiction to fossil fuels is a “Frankenstein’s monster sparing nothing and no one”, the UN secretary general, António Guterres, told leaders at the World Economic Forum in Davos on Wednesday. “Our fossil fuel addiction is a Frankenstein’s monster, sparing nothing and no one. All around us, we see clear signs that the monster has become master,”

It’s better to burn out than fade away…until it kills you.

The net zero approach of the Paris agreement has become detached from reality as it increasingly relies on science fiction levels of speculative technology.
