Sharp declines in critical mineral prices mask risks of future supply strains as energy transitions advance - News from the International Energy Agency

Extreme droogte heeft de helft van de landbouwopbrengst in Zambia vernietigd. Oxfam luidt de alarmbel: 6 miljoen mensen staan op de rand van een humanitaire crisis.

Dangers of wildfires, extreme weather and other factors outgrowing preparedness, European Environment Agency says

“100% plantaardig!”, “CO2-neutraal geproduceerd”, “Gecertificeerd voor duurzaamheid”… Klinkt goed, toch? Maar let op: wat bedrijven op hun verpakkingen en in hun marketinguitingen claimen, is niet altijd wat het lijkt. Greenwashing, oftewel het misleidend presenteren van producten of diensten als duurzaam, is helaas een wijdverspreid probleem.

Policy-makers seeking to limit the impact of coal electricity-generating units (EGUs, also known as power plants) on air quality and climate justify regulations by quantifying the health burden attributable to exposure from these sources. We defined “coal PM2.5” as fine particulate matter associated with coal EGU sulfur dioxide emissions and estimated annual exposure to coal PM2.5 from 480 EGUs in the US. We estimated the number of deaths attributable to coal PM2.5 from 1999 to 2020 using individual-level Medicare death records representing 650 million person-years. Exposure to coal PM2.5 was associated with 2.1 times greater mortality risk than exposure to PM2.5 from all sources. A total of 460,000 deaths were attributable to coal PM2.5, representing 25% of all PM2.5-related Medicare deaths before 2009 and 7% after 2012. Here, we quantify and visualize the contribution of individual EGUs to mortality.

To prevent catastrophe, these countries must stop new extraction projects n: Just 20 countries, led overwhelmingly by the United States, Canada and Russia, are responsible for nearly 90 percent of new greenhouse gas emissions threatened by new oil and gas fields and fracking wells planned between now and 2050. If these extraction projects are allowed to proceed, they will lock in climate chaos and an unlivable future.

The role of health professionals In January 2023, the science and security board of the Bulletin of the Atomic Scientists moved the hands of the doomsday clock forward to 90 seconds before midnight, reflecting the growing risk of nuclear war.1 In August 2022, the UN secretary general, António Guterres, warned that the world is now in “a time of nuclear danger not seen since the height of the Cold War.”2 The danger has been underlined by growing tensions between many nuclear armed states.13 As editors of health and medical journals worldwide, we call on health professionals to alert the public and our leaders to this major danger to public health and the essential life support systems of the planet—and urge action to prevent it. Current nuclear arms control and non-proliferation efforts are inadequate to protect the world’s population against the threat of nuclear war by design, error, or miscalculation. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) commits each of the 190 participating nations

State Farm will almost entirely stop issuing new policies in California – with climate-exacerbated wildfires and bad public policy a large reason why

Een kritische Facebookpost over een kolencentrale in zijn dorp: daarvoor hangt de Bengaalse klimaatactivist Shahnewaz Chowdhury tot tien jaar celstraf boven het hoofd. Meer dan 17.000 Belgische scholieren vragen met een briefschrijfactie van Amnesty International om de aanklacht te laten vallen.

Vast releases of gas, along with future ‘methane bombs’, represent huge threat – but curbing emissions would rapidly reduce global heating

The world is at risk of descending into a climate “doom loop”, a thinktank report has warned. It said simply coping with the escalating impacts of the climate crisis could draw resources and focus away from the efforts to slash carbon emissions, making the situation even worse.

The sediments preserved in these cliffs in Devon were laid down in the early Triassic period, just after the greatest mass extinction in the history of multicellular life that brought the Permian period to an end 252m years ago. Around 90% of species died, and fish and four-footed animals were more or less exterminated between 30 degrees north of the equator and 40 degrees south.

Joint committee on national security strategy criticises ‘severe dereliction of duty’ by ministers as threat grows

“The geopolitical situation is more difficult now than it was in 2016, but I can’t imagine that it is more difficult than in 1959,” says Brooks. “Antarctica is a space where we can do extraordinary things, and we’ve seen what countries can do when they come together in the face of crisis.” The question is whether or not the size of the climate crisis in Antarctica outweighs the political crisis in the rest of the world.

Prior research has posed a paradox of sorts: if the risk to humanity from natural hazards is so large, then why do we exist? The human species has existed for about 200,000 years, and our ancestors for even longer. Natural hazards have existed throughout this time. If they posed a significant risk, then humanity probably would have been wiped out a long time ago—yet here we are. Prior research has taken this observation about deep human history to imply a low ongoing global catastrophic risk from natural hazards, especially in comparison to anthropogenic hazards.

Healthy teenagers are more prone to irregular heartbeats after breathing in fine particulate air pollution, according to the first major study of its impact on otherwise healthy young individuals. The findings have raised concern among researchers because heart arrhythmias, which can increase the risk of heart disease and sudden cardiac death, appear to be triggered even when air pollution is within common air quality limits.

Words matter. It’s vital terms like ‘crisis’ and ‘calamity’ don’t become rhetorical devices devoid of real content as we argue about what climate action to take.

While more extreme threats are unlikely to be realised, sticking to the precautionary principle is just plain common sense. A middle of the road route would be to no one’s advantage – so, as for most situations wherein the risk is hard to quantify, there is only one sensible way forward: to hope for the best, while preparing for the worst.

Pennsylvania children living near fracking sites at birth are two to three times more likely to be diagnosed with leukemia during early childhood than those who did not live near such facilities, a new study has found.

On June 30, 2022, the Supreme Court issued a landmark opinion in West Virginia v. EPA that substantially limited the authority of the Environmental Protection Agency (the EPA) to regulate carbon emissions from power plants. Because the opinion concerned the proper scope of executive agency rulemaking, the decision may have profound effects on other regulatory agencies, including the Securities and Exchange Commission.
