Oil and gas equipment intended to cut methane emissions is preventing scientists from accurately detecting greenhouse gases and pollutants, a satellite image investigation has revealed. Energy companies operating in countries such as the US, UK, Germany and Norway appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions and pollutants at industrial facilities involved in the disposal of unprofitable natural gas, known in the industry as flaring.

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.

Unprecedented levels of damage from storms this year is upending US towns and the insurance industry
- MICHELLE CHAPMANWaves 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.

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

What else is new? Hotspots are getting hotter. The major hotspot in April stretched from Iraq to India and Pakistan, and toward the northeast through Russia (Fig. 1). Temperature exceeded 45°C (113°F) in late April in at least nine Indian cities,[1] on its way to 50°C (122°F) in Pakistan in May,[2] where a laborer says “It’s like fire burning all around” and a meteorologist describing growing heatwaves since 2015 says “The intensity is increasing, and the duration is increasing, and the frequency is increasing.” Halfway around the world, Canada and north-central United States were cooler than their long-term average, but people in British Columbia and northwest United States remember being under their own record-breaking hotspot last summer.

In 1972, a book changed the world. The Club of Rome commissioned a report that shifted how we see what humans are doing to the planet. Looking back five decades later, what happened next, what did we do and not do, what did we learn, and what happens now? In The Limits to Growth, a team from MIT studied the way humans were using the resources of the earth. Using sophisticated computer modelling, the researchers developed scenarios to map out possible paths for humanity, the global economy and the impact on the planet.
Countries should move from coal to renewable energy without shifting to gas as a “transition” fuel to save money, as high gas prices and market volatility have made the fossil fuel an expensive option, analysis has found. Natural gas has long been touted as a “transition” fuel for economies dependent on coal for their power needs, as it has lower carbon dioxide emissions than coal but requires similar centralised infrastructure, and gas-fired power stations take only a couple of years to build. Earlier this year, before Russia invaded Ukraine, the European Commission angered green campaigners by including gas as a “bridge” to clean energy in its guidebook for green investment.
