Washington:  An Indian-American scientist working with NASA has revealed how temperature and rainfall patterns may change through the year 2100 because of growing concentrations of greenhouse gases in the Earth’s atmosphere.

New high-resolution global climate data prepared by Ramakrishna Nemani, project scientist at the NASA Earth Exchange (NEX), a big-data research platform in California, can be viewed on a daily timescale at the scale of individual cities and towns.

It will help the scientists and planners in conducting climate risk assessments to understand local and global effects of hazards, such as severe drought, floods, heat waves, and losses in agriculture productivity better.

“This is a fundamental dataset for climate research and assessment with a wide range of applications,” Nemani said in a statement.

“NASA continues to produce valuable community-based data products on the NEX platform to promote scientific collaboration, knowledge sharing, and research and development,” Nemani added.

The data shows projected changes worldwide at a regional level, in response to different scenarios of increasing carbon dioxide simulated by 21 climate models.

“With this new global data-set, people around the world have a valuable new tool to use in planning how to cope with a warming planet,” noted Ellen Stofan, NASA chief scientist.

This NASA data-set integrates actual measurements from around the world with data from climate simulations.

These climate simulations used the best physical models of the climate system available, to provide forecasts of what the global climate might look like under different greenhouse gas emissions scenarios.

The NASA climate projections provide a detailed view of future temperature and precipitation patterns around the world at a 25-km resolution, covering the time period from 1950 to 2100.

The 11-terabyte data-set provides daily estimates of maximum and minimum temperatures and precipitation over the entire globe. (IANS)

The Aborted Mission To Relaunch In December: NASA

In August, a hole appeared in a Soyuz capsule docked to the ISS that caused a brief loss of air pressure and had to be patched.

The American astronaut who will hitch the first ride on a Russian rocket since last month’s aborted launch and dramatic emergency landing is confident that her scheduled trip in December on a rocket that she calls a “workhorse” will go smoothly.

Astronaut Anne McClain, along with a Russian cosmonaut and a Canadian astronaut, will man the Dec. 3 mission. It will be the Russian-made Soyuz-FG’s first crewed flight since Oct. 11, when U.S. astronaut Nick Hague and a Russian cosmonaut landed unharmed on the Kazakh desert steppe after the rocket bound for the International Space Station failed in mid-air two minutes after liftoff.

The National Aeronautics and Space Administration has relied on Russian rockets to ferry astronauts to the space station since the United States retired its Space Shuttle program in 2011, though the agency has announced plans for test flights carrying two astronauts on commercial rockets made by Boeing and SpaceX next April.

“I do see the incident that happened on Oct. 11 with our launch abort not as a failure but as a success,” McClain told Reuters in a telephone interview from Russia. “It actually bolsters my confidence in the rocket and in the processes that we have.

“We’re confident in the vehicle and getting back to it,” McClain said of the Soyuz rocket, which she called “the workhorse of the space program.”

After lifting off from Kazakhstan’s Soviet-era cosmodrome of Baikonur last month, a damaged sensor caused one of the rocket’s three booster stages to separate improperly, falling inward on the rocket and jolting it off its ascent two miles above ground, Russian investigators announced earlier this month.

Video from inside the capsule showed the two men being shaken around at the moment the failure occurred, their arms and legs flailing. Russian cosmonaut Alexei Ovchinin can be heard saying, “That was a quick flight.”

The accident was the first serious launch problem experienced by a crewed Soyuz space mission since 1983, when a crew narrowly escaped before a launchpad explosion.

In August, a hole appeared in a Soyuz capsule docked to the ISS that caused a brief loss of air pressure and had to be patched. Dmitry Rogozin, head of the Russian space agency Roscosmos, has said that it could have been made deliberately by someone during manufacturing or while the craft was in space.

McClain and two other crewmates will launch from the same launchpad in Baikonur, joining the space station’s current three-person crew. (VOA)
