Climate change not as threatening to planet as previously thought, new research suggests
Climate change poses less of an immediate threat to the planet than previously thought because scientists got their modelling wrong, a new study has found.

Climate change poses less of an immediate threat to the planet than previously thought because scientists got their modelling wrong, a new study has found. New research by British scientists reveals the world is being polluted and warming up less quickly than 10-year-old forecasts predicted.


For the First Time, Direct Observations Show Increasing Greenhouse Effect

The rising concentration of carbon dioxide at the Earth’s surface is increasing the amount of heat the air can absorb, measurements taken by scientists at the US Department of Energy’s Berkeley Lab have shown. 

This phenomenon, they say, is being caused by rising CO2 levels from burning fossil fuels and fires, and the data fits with models that take into account the effect of human activity on the atmosphere.

“We see, for the first time in the field, the amplification of the greenhouse effect because there’s more CO2 in the atmosphere to absorb what the Earth emits in response to incoming solar radiation,” said Daniel Feldman, a Berkeley Lab project scientist who specializes in comparing climate models with actual instrument observations. He is the lead author of a paper published in the journal Nature on Feb. 25.

Fic prompt: AU - Felicity is a virgin and somehow ends up in a hotel room with Oliver Queen, multi billionaire playboy. She's nervous but trying not to show it, and she expects him to go fast and not care about how she feels. She's surprised when he's very gentle and asks if she's okay all the way through. She's even more surprised when he stays in bed the next morning, and officially asks her out.


(AN: This one totally got away from me and ended up being 7K words of delicious smut. Oops! Oh, what am I saying? It’s SMUT! Of course y’all are gonna like it!)

It started out with her bumping into him in the lobby, then again in the hotel gym, and finally, in the hot tub and it just seemed to escalate from there because, holy shit! Oliver Queen, billionaire playboy, was actually interested, in her, little old Felicity Smoak, the mousey IT girl from the server room. But here she was, lounging in the hot tub, oblivious to anything aside from the warm water lapping around her body.

The peaceful solitude was interrupted by footsteps making her eyes pop open immediately to see who had walked in. Felicity’s jaw dropped. There was Oliver wearing a pair of baggy black track pants, a towel casually tossed over his shoulder. Beads of sweat dotted his bare chest glistening in the pale twilight that filtered through the large glass windows that surrounded the area. She watched him from the bubbling hot water as he made his way to a chair on the opposite side of the hot tub, his attention clearly elsewhere. He was humming along with whatever music was streaming into his headphones, but when he finally looked in her direction, he froze.

Felicity’s arms stretched out along the edges of the brick tub allowing her head to tilt back slightly and her breasts to bob with the swirling waters. She felt her breath catch as her stomach fluttered when his eyes settled upon her. His lips twitched up when his gaze fell lower and settled on her chest. She felt slightly self-conscious, dipping down into the water when his stare remained fixed on her. But she managed to stand her ground, staring back at him the way he had been staring at her, appreciating the fine lines of his chiseled chest and arms.

Something fluttered much lower in her body and for a moment, Felicity thought the heat was getting to her. She took a deep breath to clear her head and apparently so did he. As he walked towards the edge of the tub, she watched the muscles ripple beneath his skin with every step he took. Adonis, the god of beauty and desire, popped into her head. That he was. Felicity licked my lips.

As her own private Adonis reached the edge of the tub, she sat up, keen on watching him take off his pants to see what lay beneath. Her eyes dropped. She couldn’t believe where her mind had gone in those short minutes of first making eye contact. Chiding the part of her brain that wanted to indulge in fantasy, she coyly looked up to see he had on a pair of black swim trunks beneath his trainers. Although relieved, Felicity knew in a moment he’d be sitting opposite her in the small tub.

When viewed in just the right way, Earth is covered in swirling brushstrokes that put Van Gogh’s most famous works to shame. Differences in temperature and pressure, friction and other phenomena cause fluids like water in the ocean and air in the atmosphere to move in mesmerizing patterns. Sometimes it just takes a supercomputer to see the dance. 

These images represent the next generation of ocean current models that reveal some of the hidden action. Produced by the Department of Energy’s Los Alamos National Lab, the top image shows Atlantic Ocean water surface temperatures and the bottom illustrates the Southern Ocean’s currents and eddies flowing eastward around Antarctica. 

Both are part of the lab’s Climate, Ocean and Sea Ice Modeling program to project global alterations to the planet from climate change using the most advanced technologies and methods. Models were built using a supercomputer that operates 8,000 processors simultaneously and verified against real-world satellite and shipboard observations.

Climate scientists join search for alien Earths

NASA initiative seeks to bolster interdisciplinary science in hunt for extraterrestrial life.

By Jeff Tollefson

The hunt for life beyond the Solar System is gaining new partners: NASA climatologists. After more than 30 years of studying Earth, a team at the NASA Goddard Institute for Space Studies (GISS) in New York will adapt its global climate model to simulate conditions on potentially habitable exoplanets. The effort is part of a broader push to identify Earth-like worlds that NASA will launch on 20 April at a meeting in Washington DC.

Already, the agency’s space-based Kepler telescope has pinpointed more than 1,000 alien planets by observing the brief interruption of starlight that signals a planet passing in front of its parent star. At least five of these planets are similar in size to Earth and located in the ‘habitable zone’, where liquid water could persist. The next step would be to detect light passing through exoplanet atmospheres, which could hold clues to conditions on these distant worlds.
