f global warming reaches or exceeds two degrees Celsius by 2100, University of Western Ontario's Joshua Pearce says it is likely that mainly richer humans will be responsible for the death of roughly one billion mainly poorer humans over the next century. The oil and gas industry, which includes many of the most profitable and powerful businesses in the world, is directly and indirectly responsible for more than 40% of carbon emissions—impacting the lives of billions of people, many living in the world's most remote and low-resourced communities. A new study proposes aggressive energy policies that would enable immediate and substantive decreases to carbon emissions and recommends a heightened level of government, corporate and citizen action to accelerate the decarbonization of the global economy, aiming to minimize the number of projected human deaths.
Avec Jeff Bezoz, il veut sauvegarder 58 millions d'hectares et protéger les populations indigènes.
Si les chefs d'Etat et dirigeants d'institutions financières internationales réunis jusqu'à vendredi à Paris pouvaient reconnaître ensemble qu'il faut réparer la finance mondiale pour atteindre les objectifs climatiques, cela serait "historique", estime l'économiste du développement américain Jeffrey Sachs.
Unearthly skies and unhealthy air resulting from Canadian wildfires may persist for days.
Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America (change in annual risk from 32% in 2015 to 49% in 2100) and Europe (32% to 53%) in the most extreme emissions scenario. Following low-end and medium scenarios compared to high-end scenarios indicates a notable reduction in annual flash drought risk over cropland. Flash droughts are projected to become more frequent unde
Le changement climatique pose un problème complexe et sans précédent. Avec la hausse des températures, le climat mondial devient de plus en plus instable. Les incidences sur le climat, telles que l’élévation du niveau de la mer et la fréquence des phénomènes météorologiques extrêmes, ont de graves répercussions sur les systèmes écologiques et humains. Bien que le changement climatique soit un phénomène mondial, des conséquences uniques et graves se produisent à l’échelle locale. Une érosion côtière incontrôlable, des inondations dévastatrices ou des températures extrêmes atypiques peuvent facilement submerger une communauté non préparée. Les incidences sur le climat risquent d’être coûteuses : en 2025, le Canada devrait subir des pertes de 25 milliards de dollars en raison du changement climatique, et d’ici 2100, les pertes annuelles pourraient atteindre 100 milliards de dollars (Sawyer et coll., 2022). Ces risques soulignent l’importance de l’adaptation, le processus par lequel les communautés anticipent et

The State of Climate Action 2022 report analyzed progress across 40 indicators of action needed by 2030 and 2050 to limit warming to 1.5 degrees C, everything from increasing renewable energy uptake to halting deforestation to shifting to more sustainable diets. We found that none of the 40 indicators assessed are on track to achieve 2030 targets.
Increasing risks posed by climate change are causing rare extreme events that can kill more than 10 million people or lead to damages of $10 trillion-plus, posing threats of total societal collapse, a UN report finds.
La vague de chaleur brutale et d’un degré record d’intensité qui s’est abattue sur une grande partie de l’Inde et du Pakistan depuis le mois de mars s’est quelque peu calmée cette semaine [de début mai], mais elle est sur le point de se relancer dans les jours à venir, avec des températures infernales pouvant atteindre 50 degrés Celsius.
Our study assessed whether the opportunity to see many vertebrate animal species mattered to tourists visiting Costa Rica, and if so, how important it was compared with other features like hotels and beaches. in Costa Rica, our research shows that biodiversity needs to be paired with infrastructure like hotels and roads that enable access to nature.
