2018 Fourth-hottest Year Since 1880; Earth Set to Get Warmer, Says NASA

"The impacts of long-term global warming are already being felt a" in coastal flooding, heat waves, intense precipitation and ecosystem change," said Schmidt

Earth’s global surface temperatures in 2018 were the fourth warmest since 1880 and the planet will warm further, especially since greenhouse gas emissions are continuing to rise, Nasa and the National Oceanic and Atmospheric Administration (NOAA) have said.

Global temperatures in 2018 were 0.83 degrees Celsius warmer than 1951 to 1980, according to scientists at Nasa’s Goddard Institute for Space Studies (GISS) in New York.

Globally, 2018’s temperatures ranked behind those of 2016, 2017 and 2015. The past five years are, collectively, the warmest years in the modern record.

“2018 is yet again an extremely warm year on top of a long-term global warming trend,” GISS Director Gavin Schmidt said in a statement on Wednesday.

Since the 1880s, the average global surface temperature has risen about 1 degree Celsius.

This warming has been driven in large part by increased emissions into the atmosphere of carbon dioxide and other greenhouse gases caused by human activities.

“Weather dynamics often affect regional temperatures, so not every region on Earth experienced similar amounts of warming,” said NOAA.

Warming trends are strongest in the Arctic region, where 2018 saw the continued loss of sea ice.

“In addition, mass loss from the Greenland and Antarctic ice sheets continued to contribute to sea level rise.

“Increasing temperatures can also contribute to longer fire seasons and some extreme weather events.

“The impacts of long-term global warming are already being felt a” in coastal flooding, heat waves, intense precipitation and ecosystem change,” said Schmidt. (IANS)

SpaceX Plans To Send NASA Astronauts To Space in Q2 This Year

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff

After NASA and SpaceX successfully completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket, Elon Musk said that his aerospace company aims to send NASA astronauts to space between April and June this year.

This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station (ISS) under NASA’s Commercial Crew Programme, the US space agency said in a statement on Sunday.

With this test now complete, the next big flight of the Crew Dragon will have people on board: NASA astronauts Bob Behnken and Doug Hurley.

“We’re highly confident that the hardware will be ready in Q1, most likely at the end of February but no later than March. And we think it appears probable that the first crewed launch would occur in the second quarter,” said Musk after the successful uncrewed test of its Crew Dragon capsule’s in-flight launch escape capabilities.

Musk said that if all goes well, the first crewed flight on the Crew Dragon could take place in the second quarter of this year.

“This critical flight test puts us on the cusp of returning the capability to launch astronauts in American spacecraft on American rockets from American soil,” said NASA Administrator Jim Bridenstine. “We are thrilled with the progress NASA’s Commercial Crew Programme is making and look forward to the next milestone for Crew Dragon.”

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff. All major functions were executed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down at 10:38 am just off the Florida coast in the Atlantic Ocean.

“As far as we can tell thus far, it’s a picture perfect mission. It went as well as one can possibly expect,” said Musk. “This is a reflection of the dedication and hard work of the SpaceX and NASA teams to achieve this goal. Obviously, I’m super fired up. This is great.”

Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams now will begin the full data reviews that need to be completed prior to NASA astronauts flying the system during SpaceX’s Demo-2 mission. “The past few days have been an incredible experience for us,” said astronaut Doug Hurley.

“Today, we watched the demonstration of a system that we hope to never use, but can save lives if we ever do. It took a lot of work between NASA and SpaceX to get to this point, and we can’t wait to take a ride to the space station soon,” he said in the NASA statement. (IANS)
