Tierney wrote a better article than I could Tuesday about why the legacy for the ages that can happen in our lifetimes is the first footprints on Mars. The sponsor could be remembered as the next “Prince Henry the Navigator, King Ferdinand, [or] Queen Isabella”. This is an argument I implied here in a scholarly way and in passing here in a grandiose way and a whimsical way here. In the process I attempt to refute Jeff Bell and James Van Allen who are both opposed.

Did an extraterrestrial impact cause the Ice Age extinctions? If so, this could be one more motivation to get our act together in terms of finding and managing these things.

A tutorial. This should be of interest to anyone in hurricane country. In many ways, wind shear is a more important factor in the intensity of storms than water temperature (one reason that the effect of global warming, if it occurs, is not obvious, with respect to more or more intense hurricanes).

Supergerms. No word on whether or not kryptonite has any effect.

Is most scientific research sloppy?

I wouldn’t be shocked if that were the case. We see enough examples of it (global warming being one notable area) to think that it could be just the tip of the iceberg. Getting it right is hard work, and there are a lot of researchers out there who are desperately working on degrees, or under the pressure to publish or perish, even if the research turns out to be perishable.

The Earth is just about half-way through the agricultural revolution where one worker can on average produce food for two workers and their dependents now. From the beginning of the agricultural revolution that freed up folks to make other goods and services around 1750-1850 to today where we have only half of workers worldwide give or take working in agriculture, 6 times as many people and 35% more calories per person from 1960-1990 alone.¹

Compare that to the BBC radio report saying that since the dawn of the PC revolution (I got my Apple ][+ with disk drive and language card mail order near the dawn of the personal computer revolution in 1983). We are nearly at one billion PCs worldwide and on a pace for 3.5 billion PCs worldwide in about ten years.² Interesting times indeed.

Jim Hansen has released the code for his models.

Whether it’s increasing the salinity of the oceans, or decreasing it, we know who to blame.
