Rising methane levels impact climate change

By the year 2000, methane levels in the atmosphere were thought to have stabilised, but now they are again on the rise, exacerbating climate change. Why is this happening?

By the year 2000, methane levels in the atmosphere were thought to have stabilised. But just a few years later, in 2007, these levels suddenly started to rise. Research suggests that the spread of intense farming in Africa may be involved, in particular in tropical regions, where conditions are becoming warmer and wetter because of climate change.

The awe-inspiring Japanese Hayabusa 2 space mission achieved another milestone on the other side of the Sun. This remarkable craft touched down on the asteroid Ryugu, firing a bullet into the surface, and collecting samples of rock for eventual delivery to Earth.
