Stratosphere shrinkers

Thinning indicates a profound impact of humans and could affect satellites and GPS Humanity’s enormous emissions of greenhouse gases are shrinking the stratosphere, a new study has revealed. The thickness of the atmospheric layer has contracted by 400 metres since the 1980s, the researchers found and will thin by about another kilometre by 2080 without major cuts in emissions. The changes have the potential to affect satellite operations, the GPS…

Kill to Save?!

Botswana and South Africa are encouraging limited hunting of species nearing extinction ... to rescue them. Sound crazy? They’ve concluded that banning hunting altogether leaves poor local communities vulnerable to bribes from poachers. Instead, they’re allowing strictly regulated trophy hunting and game farming. That creates a local economy that benefits communities situated next to wildlife-rich regions, giving them an incentive to ensure endangered species survive. It’s an approach that’s worked…

China: Mining vs. climate

China powers nearly 80% of the global cryptocurrencies trade, but the energy required could jeopardize its pledge to peak carbon emissions by 2030 China’s electricity-hungry bitcoin mines that power nearly 80% of the global trade in cryptocurrencies risk undercutting the country’s climate goals, a study in the journal Nature has said. Bitcoin and other cryptocurrencies rely on “blockchain” technology, which is a shared database of transactions, with entries that must…
