If currently implemented policies are continued with no increase in ambition, there is a 90% chance that the Earth will warm between 2.3°C and 4.5°C, with a best estimate of 3.5°C.
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.
From October 28-31, 2021, public hearings has been held in the 'Court for Intergenerational Climate Crimes' (CICC) against various transnational corporations ...
This Southern Ocean warming and its associated impacts are effectively irreversible on human time scales, because it takes millennia for heat trapped deep in the ocean to be released back into the atmosphere. This means changes happening now will be felt for generations to come – and those changes are only set to get worse, unless we can stop carbon dioxide emissions and achieve net zero.
Ember modelling of least-cost power system pathways reveals that a clean power system (70-80% wind and solar) by 2035 should be at the core of energy planning for a net-zero continent by mid-century.
The war in Ukraine is laying bare a generational divide over what lessons Germany should draw from its own history of waging bloody conflicts, as some of the country’s leading artists and intellectuals line up in favour of or against supplying Kyiv with weapons in a series of open letters.
It may take bees multiple generations to recover from being exposed to insecticides even just once, research shows. A new research, published in PNAS, shows that even a single exposure to insecticides in a bee’s first year of life affects offspring production, and since the effects of the pesticides are cumulative, this results in an overall decrease in population
People born in 2020 will have to face between two and seven times more extreme climate-related events over their lifetimes than people born in 1960, according to estimates from a new study.
By continuing to delay significant reductions in greenhouse gas emissions, we risk handing young people alive today a bill of up to US$535 trillion. This would be the cost of the “negative emissions” technologies required to remove CO₂ from the air in order to avoid dangerous climate change.
Dennis Meadows: The notion that there is some kind of fairly attractive sustainable society ahead of us if we can only find it is now a fantasy. The global population, its use of materials, its generation of wastes has grown so far above the sustainable capacity of the planet that there is nothing ahead [of the kind] that the sustainable utopia people are talking about.
the court found that one million of today’s Australian children are expected to be hospitalised because of a heat-stress episode, that substantial economic loss will be experienced, and that the Great Barrier Reef and most of Australia’s eucalypt forest won’t exist when they grow up. It found this harm is real, catastrophic, and – importantly from a legal perspective – “reasonably foreseeable”.
