European countries are pushing back against attempts at weakening the rules governing the first global pact on aviation emissions. But even if successful, these states themselves are finding aviation just dang hard to decarbonize. We explain why.
The rate of Antarctic ice sheet melt has tripled in the past decade after an acceleration that started around 2002, according to a review of multiple ice loss studies. The researchers conclude that the melt is raising sea levels half a millimetre every year.
Only small amounts of sequestered carbon is likely to leak out
Over 90 percent of CO2 sequestered deep underground is likely to stay there for at least 10,000 years, according to a new study appearing in Nature. The researchers wanted a realistic assessment of carbon capture and storage, having suspected that both claims of perfect storage and dangerous leakage were false.
Share of clean sources in global power sector fuel mix lower than in 1998
Despite huge growth in renewables in recent years, the share of coal in the global power sector fuel mix in 2017 was 38% – exactly the same as in 1998, according to the widely anticipated annual World Energy Review from BP. The share of non-fossil-based electricity in 2017 is slightly lower than it was 20 years ago, as the growth of renewables has not offset the declining share of nuclear.
