Has Nasa found life on Mars? Speculation mounts ahead of press conference to unveil “a major science finding”
The space agency has scheduled a press conference for Monday, in which it promises to announce a “Mars Mystery Solved”.
While many are hoping for a discovery of alien life, the leading theory among those who follow research into Mars is an announcement of the presence of liquid water.
Nearly 50 former NASA scientists, astronauts and technologists are chastising NASA for its position on man-made climate change.
In a March 28 letter addressed to NASA Administrator Charles Bolden, the group of 49 former employees ask NASA and the Goddard Institute for Space Studies to “refrain from including unproven remarks in public releases and websites” because “it is clear that the science is NOT settled.”
“As former NASA employees, we feel that NASA’s advocacy of an extreme position, prior to a thorough study of the possible overwhelming impact of natural climate drivers is inappropriate,” the letter reads.
Prolonged winters, advancing glaciers, colder summers, more frequent storms and extended cloudiness reduced arable land, shortened growing seasons, rotted grain in wet fields, and brought famine, disease and death. Coming after the prosperous Medieval Warm Period – when farmers grew wine grapes in England and Vikings raised crops and cattle in Greenland – it must have been quite a shock.
The LIA underscored how much better a warmer planet is than a colder one. Moderate warming above today’s norm would likely bring expanded cultivation during longer growing seasons in northern latitudes, fewer people dying from hypothermia during frigid winters, and many other benefits.
