And Munich Re data nicely illustrates how the global trend in climate disasters has escalated while the trend in geophysical disasters (eg earthquakes) has not. This divergence couldn’t happen if the increase in climate disasters was due to increasing wealth.

A rad in the raw video view of what the beginning of today's looked like through my telescope in South Africa. (false color added for theatrical effect, of course)

Amazing photo by of an elephant mosquito larva (Toxorhynchites towadensis) munching on a smaller mosquito larva. Because they feed on larvae of blood-sucking mosquitoes and rarely feed as adults, Toxorhynchites are beneficial to us. Click the link for more photos!

It seems at 7.7 x 10^50 kg (or 3.9 x 10^20 solar masses) that ice cream cube is already a black hole with an event horizon of 120.9 Mly. But that is so large do we even care.

image of a 1500 km cloud forming over the summit of Arsia Mons. This cloud isn't a sign of an eruption at the 20 km high volcano -- it's an orographic cloud that usually forms every morning for a few months Mars is closest to the Sun.
