Coal and gas exports expected to remain roughly at current level until at least 2035 with 4.5% of emissions linked to Australia, report finds

Scientists now fear that there is little more than five years left to prevent irreversible climate damage and stark changes to the Earth’s weather patterns from global carbon emissions, Minister for Climate Eamon Ryan has warned.

Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average tempe

04/17/2024 - Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.

De COP28-klimaattop opent al meteen met een doorbraak: de goedkeuring van een langverwacht fonds voor verlies en schade. Milieu- en ontwikkelingsorganisaties juichen de “historische beslissing” toe.

Donderdag start in Dubai een - alweer cruciale - VN-klimaattop. Begrippen als INDC’s, emissiehandel en loss and damage zullen ons dus weer twee weken lang om de oren vliegen. Tijd voor een opfrissing van ons klimaatjargon.

Waves of severe thunderstorms in the U.S. during the first half of this year led to $34 billion in insured losses, an unprecedented level of financial damage in such a short time as climate change contributes to the frequency and severity of violent meteorological events. The reinsurer Swiss Re Group said Wednesday that damages from convective storms in the U.S., which can come with hail, lightning, heavy rain and high winds, accounted for nearly 70% of the $50 billion in global catastrophic damages so far this year. The storms in the U.S. were so severe, there were 10 that resulted in damages of $1 billion or more, almost double the average over the last decade.

Kwetsbare landen zoals Malawi hebben vandaag een actieplan nodig om zich te weren tegen de gevolgen van de klimaatverandering. Ze kunnen niet wachten tot er over compenserende maatregelen voor hun verliezen wordt onderhandeld op een volgende klimaattop.

Verschillende experts ter zake delen hun inzichten over welke kwesties het klimaatdebat het komende jaar zullen beheersen.

Van enorme overstromingen in Pakistan en extreme droogte in Europa, tot doorbraken op het vlak van milieubescherming en plastic: de wereld beleefde opnieuw een goed gevuld klimaatjaar in 2022. De impact van de Russische invasie in Oekraïne liet zich op zowat alle domeinen voelen.
