Space-based quantification of per capita CO2 emissions from cities

Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship …

Tropical rainfall on the rise as big storm events increase, study finds

Rainfall is increasing in the tropics across the world with the rise attributed to more big thunderstorms, new research by an Australian-led team has found. While observations and models have found that "wet gets wetter" and "warmer gets wetter", the mechanism of what has been going on has been unclear. …

NASA's Most Powerful Rocket Boosters Shook Utah This Week

The 1.6 million pound boosters of NASA's new flagship rocket, the Space Launch System (SLS) filled the test faculties in Promontory, Utah on Wednesday, with their propellant heating up to just about 90 degree Fahrenheit even as rocket jets that could melt your face off left each booster's end. It's …

Could China & India's Air Pollution be behind our Cold, Snowy Winters?

It's March. It's freezing. And there's half a foot of snow on the ground. When is this winter going to end? Many scientists think that climate change might be one cause of this year's "snowpocalypse" in Boston and bitter cold snaps in New York and Washington. But physicists at NASA's …

CO2 increase may intensify future droughts in tropics

A new study suggests that increases in atmospheric CO2 could intensify extreme droughts in tropical and subtropical regions -- such as Australia, the southwest and central United States, and southern Amazonia -- at much a faster rate than previously anticipated, explains University of Texas at Austin professor Rong Fu in …

The big melt: Antarctica’s retreating ice may re-shape Earth

From the ground on Cape Legoupil in the extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging far below to reshape Earth. Water is eating away at the ice, melting it where it hits the oceans. As …

Snow and rain in unprecedented detail: Mesmerising Nasa timelapse reveals Earth's precipitation over a year

A mesmerising time-lapse of the world's rainfall and snowfall over the past year is being used by Nasa to track the factors behind climate change. It is the most detailed map of Earth's precipitation that has ever been created and allows scientists to follow the planet's weather patterns in near …

Global sea ice diminishing, finds new NASA study

Earth has been shedding sea ice at an average annual rate of 35,000 square kilometres since 1979, a new NASA study has found. “Even though Antarctic sea ice reached a new record maximum this past September, global sea ice is still decreasing,” said Claire Parkinson, author of the study and …

Earth's Dashboard Is Flashing Red—Are Enough People Listening?

A Pew Research Center survey, released last week as part of a broader report on science and society, found that only 50 percent of Americans believe that humans are mostly responsible for climate change, while 87 percent of scientists accept this view. This 37-point gap persists even though thousands of …

NASA launches climate change-observing satellite on third try

Amid growing concern about global weather patterns, a rocket roared into space Saturday carrying a NASA satellite that will give scientists new tools to forecast weather, track drought and monitor climate change. The liftoff from Vandenberg Air Force Base in Southern California was the third attempt to launch the craft. …

Climate models don't over-predict warming, Nature study shows

If you listen to climate change sceptics, Earth's surface hasn't warmed appreciably in the last 15 years, and any "record" set last year is just the result of the planet doing what the planet naturally does. It turns out they're right, but for the wrong reasons, according to a study …

Travel plans go haywire as Met predicts foggy days ahead

Dense fog continued to ruin travel plans in North India on Sunday with over 100 flights and 60 North-bound trains getting delayed in Delhi alone. The intensity of fog is set to increase across North India in the coming few days. The India Meteorological Department has issued a warning for …

Last year was Earth's hottest on record, U.S. scientists say

Last year was Earth's hottest on record in new evidence that people are disrupting the climate by burning fossil fuels that release greenhouse gases into the air, two U.S. government agencies said on Friday. The White House said the studies, by the U.S. space agency NASA and the National Oceanic …

Greenland Meltwater Contributes to Rising Sea Levels

As the largest single chunk of melting snow and ice in the world, the massive ice sheet that covers about 80 percent of Greenland is recognized as the biggest potential contributor to rising sea levels due to glacial meltwater. Until now, however, scientists’ attention has mostly focused on the ice …

NASA’s year of climate change research kicks off, with a little help from Washington companies

The space agency is kicking off five global projects designed to study how the earth’s atmosphere influences climate change. One of those projects is a study of greenhouse gases over the eastern part of the United States, with a little help from Washington-area contractors. Scientists think they understand what causes …

Coal, Not Fracking Blamed for U.S. Methane Hot Spot

A tiny patch of the southwestern U.S. produces the nation’s highest concentrations of methane, the potent greenhouse gas that President Barack Obama has vowed to tackle as part of his assault on climate-change pollution. The hot spot near the intersection of Arizona, Colorado, New Mexico and Utah accounts for almost …

Satellites See Hot Spot Of Methane In U.S. Southwest

WASHINGTON (AP) — A surprising hot spot of the potent global-warming gas methane hovers over part of the southwestern U.S., according to satellite data. That result hints that the U.S. Environmental Protection Agency and other agencies considerably underestimate leaks of methane, which is also called natural gas. The higher level …

Antarctic sea ice at record high: NASA

NEW YORK: Sea ice around Antarctica has reached its highest level since measurement started in 1979, NASA said. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice record …

Chunk of Aral Sea, one of the largest lakes, dries up

The eastern basin of the Aral Sea — formerly one of the four largest lakes in the world — has for the first time dried up completely, according to latest images released by Nasa. The once-extensive lake in Central Asia has been shrinking markedly since the 1960s, but for the …

Satellite images show Aral Sea basin 'completely dried'

A large section of the Aral Sea has completely dried up for the first time in modern history, according to Nasa. Images from the US space agency’s Terra satellite released last week show that the eastern basin of the Central Asian inland sea – which stretched across Kazakhstan and Uzbekistan …

India Beats China to Mars Orbit at 11% Cost of U.S. Probe

A $74 million Indian spacecraft entered orbit around Mars today after an almost yearlong voyage, and for 11 percent the cost of the U.S.’s Maven probe. Mangalyaan, or “Mars craft” in Hindi, made orbit after a trip of about 661 million kilometers (411 million miles), the Indian Space Research Organization …
