if the entire Earth was covered by water - a so-called ocean planet - the average temperature on the planet would rise to almost 27 C.

In 2021, scientists reported that Earth dimmed by ~0.5% over two decades (1998-2017) as measured by earthshine using modern photometric techniques. This may have both been co-caused by climate change as well as a substantial increase in global warming. However, the link to climate change has not been explored to date and it is
