Emergency? Part 4

Legal Planet

Methane has a comparatively short life in the atmosphere (about 12 years, as opposed to 100 years or more for CO2) and high potency (84 times stronger than CO2, averaged over 20 years). The latter policy requires a 40% reduction of methane emissions across all sectors by 2030. Next time: ending deforestation.

Space for all: here are some of the huge commercial opportunities away from Earth

Physics World

Indeed, the global satellite internet market, which was worth $2.93bn in 2020, is projected to rise to $18.59bn by 2030. Weighing just 260 kg each, they will fly in very-low-Earth orbit at heights of roughly 550 km, which means that atmospheric drag will pull them down within a few years so they don’t end up as yet more space junk.
