During the last 3 billion years, life on Earth has survived 7 mass extinctions. In each one more than 70% of the Earth’s species vanished. While the dominant species were wiped away, life recovered and vacant niches were filled by evolution. Some of the prominent victims of mass extinction live on in radically different form and ecological function like birds: Think about dinosaurs and birds.
Needless to say, if the the human race stays around for long enough, we might also face such an event. Additionally, a lot can be learned from the thought experiment, how we might cope and what strategies we might develop in order to survive.
Unfortunately, “Scatter, Adapt, and Remember ” by Annalee Newitz cannot live up to its promising title.

But seriously - A message from the creator of these graphs (BBC):
1) Be critical of statistics that you see
2) Look for a causal link or mechanism
3) Demand a little bit of scientific rigour in showing that there’s a strong, statistically significant correlation
Or in other words, when you make a computer data-mine hundreds of data-sets and calculate correlations you are bound to find some interesting correlations.
Study: Black college grads have double the unemployment rate | Al Jazeera America -
At age 33 and boasting an Ivy League graduate degree, Kitama Cahill-Jackson never thought he’d end up a security guard.
But after years of layoffs and coming in second in job interviews, the Emmy Award–winning documentary filmmaker took the job.
Cahill-Jackson dreamed of a career as a news producer. But now, after years of unsuccessfully searching for journalism jobs, he said he can’t even look at the news.
“When I got to work at 4:30 in the morning, I would listen to NPR. I don’t listen anymore because it makes me sad. That’s the career I didn’t have,” he said.
“I don’t read the paper because it breaks my heart. It breaks my heart that I put on this uniform every day and come in here, and I’m not seen as a professional. I worked so hard academically, and for all of that, to work at a job that only requires a GED.”
Cahill-Jackson is among the more than half of black college graduates who are underemployed, according to a study (PDF) released by the Center for Economic Policy and Research this month.
Recent black college grads ages 22 to 27 have an unemployment rate of 12.4 percent, more than double the 5.6 percent unemployed among all college grads in that demographic and almost a threefold increase from the 2007 level of 4.6 percent, before the Great Recession took its toll on the U.S. economy. More than half of black graduates, 55.9 percent, are underemployed.
Even for those who enter the science, technology, engineering and math (STEM) fields, areas where grads are the most needed and paid the highest, African-Americans still have a 10 percent unemployment rate and a 32 percent underemployment rate.
The study’s authors blame racism, a faltering economy and an unequal playing field.

Lets have an honest debate about anthropogenic climate change:
Real climate scientists explain, what is happening
The IPCC has produced a video on its Fifth Assessment Report (AR5). The first part on the Working Group I contribution to AR5 is now available. The other parts will be released with the successive approvals of the other two Working Group contributions and the Synthesis Report in the course of 2014.
