Chief greenhouse gas hits two-million-year high

For first time in 2 million years, levels of chief greenhouse gas hit 400 parts per million

By Associated Press, The Associated Press

WASHINGTON – Levels of heat-trapping carbon dioxide in the air are now the highest they’ve been in about 2 million years.

Pieter Tans, who monitors levels for the U.S. government, says carbon dioxide levels have hit 400 parts per million.

When measurements of this chief greenhouse gas were first taken in 1958, carbon dioxide levels were at 315. Levels are now growing about 2 parts per million per year.

That’s 100 times faster than at the end of the Ice Age. The measurements taken in Hawaii, at the world’s oldest monitoring station, are considered the global benchmark. Last year, regional monitors briefly hit 400 ppm in the Arctic. Generally carbon levels peak in May then fall slightly.

Pentagon successfully tests hypersonic flying bomb

By AFP

WASHINGTON — The Pentagon on Thursday held a successful test flight of a flying bomb that travels faster than the speed of sound and will give military planners the ability to strike targets anywhere in the world in less than a hour.

Launched by rocket from Hawaii at 1130 GMT, the “Advanced Hypersonic Weapon,” or AHW, glided through the upper atmosphere over the Pacific “at hypersonic speed” before hitting its target on the Kwajalein atoll in the Marshall Islands, a Pentagon statement said.

Kwajalein is about 2,500 miles (4,000 kilometers) southwest of Hawaii. The Pentagon did not say what top speeds were reached by the vehicle, which unlike a ballistic missile is maneuverable.

Scientists classify hypersonic speeds as those that exceed Mach 5 — or five times the speed of sound — 3,728 miles (6,000 kilometers) an hour. …
