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 …
The Antarctic ozone hole has swelled this month to one of its biggest sizes on record, UN and US scientists say, insisting that the Earth-shielding ozone layer remains on track to long-term recovery but residents of the southern hemisphere should be on watch for high UV levels in the weeks …
The U.N.'s weather and climate agency said on Thursday there was no cause for alarm about a record-size hole this month in the ozone layer, that shields life on earth from the sun, as it should shrink again. The ozone hole that appears over Antarctica fluctuates in size, normally reaching …
Strongest El Niño in decades, will have wide-ranging effects It has choked Singapore with smoke, triggered Pacific typhoons and left Vietnamese coffee growers staring nervously at dwindling reservoirs. In Africa, cocoa farmers are blaming it for bad harvests, and in the Americas, it has Argentines bracing for lower milk production …
India will now be one of the many countries where Nasa's airborne hyperspectral imaging campaign will take place which will closely monitor various changes taking place in the earth's atmosphere and capture high resolution images through the spectrometer developed by Nasa's Jet Propulsion Laboratory (JPL). Alok Chaterjee, scientist at the …
The pledges that countries are making to battle climate change would still allow the world to heat up by more than 6 degrees Fahrenheit, a new analysis shows, a level that scientists say is likely to produce catastrophes ranging from food shortages to widespread extinctions of plant and animal life. …
Researchers say discovery of stains from summertime flows down cliffs and crater walls increases chance of finding life on red planet Liquid water runs down canyons and crater walls over the summer months on Mars, according to researchers who say the discovery raises the chances of being home to some …
The melting of the Arctic permafrost and the subsequent release of carbon dioxide and methane gas into the atmosphere will alone add an extra $43 trillion (£33tn) cost of climate change to the global economy by the end of the next century, scientists have calculated. This represents a 13 per …
Global temperature records continue to tumble, with August easily the hottest in 124 years of data, Japan's Meteorological Agency says. Last month, near-surface land and sea temperatures were 0.45 degrees higher than the 1981-2010 average, eclipsing the previous biggest anomaly for August of 0.33 degrees set last year. The massive …
Meteorologists are churning through the alphabet to come up with new names for storms, as what US space agency NASA dubs the "tropical train" spawns yet another cyclone. Hurricane Linda is the latest tropical storm to achieve hurricane strength as the depression strengthened quickly on Monday off the southern tip …
Rising sea levels caused by melting ice caps could threaten Nasa launch sites along US coastlines, the US space agency has warned. In the coming years, launch facilities at Florida's Kennedy Space Centre and other places may need to be retrofitted or even moved inland, Nasa said. "Every Nasa centre …
A new NASA joint project will provide timely weather, climate and other Earth related data to five countries in Southeast Asia, enabling them to better address issues of natural resource and disaster management. NASA and the US Agency for International Development (USAID) have launched SERVIR-Mekong project to strengthen regional environmental …
PARIS – Diplomats will gather in Bonn from Monday to thrash out the draft of a climate pact to be adopted at a U.N. conference in Paris in December. With just 10 official negotiating days before 195 nations must seal the deal in the French capital, time is running out …
MIAMI: Sea levels are rising around the world, and the latest satellite data suggests that three feet (one metre) or more is unavoidable in the next 100-200 years, Nasa scientists said on Wednesday. Ice sheets in Greenland and Antarctica are melting faster than ever, and oceans are warming and expanding …
Global sea levels have risen nearly 3 inches in less than 25 years, with some locations around the world rising more than 9 inches, according to NASA’s latest satellite data. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet …
The presence of vegetation in urban areas - along the roads, in the parks and in your neighbourhood - can limit city heat effect to a great extent, says a Nasa study. Using multiple satellites' observations, researchers found that areas in the US covered in part by concrete surfaces had …
Sea levels worldwide have risen an average of nearly eight centimetres (three inches) since 1992 because of warming waters and melting ice, a panel of Nasa scientists said on Wednesday. In 2013 a United Nations panel predicted sea levels would rise from between 0.3 and 0.9 metres by the end …
MIAMI – Sea levels are rising around the world, and the latest satellite data suggest 3 feet (1 meter) or more is unavoidable in the next 100 to 200 years, NASA scientists said Wednesday. Ice sheets in Greenland and Antarctica are melting faster than ever, and oceans are warming and …
Parts of the San Joaquin Valley in Central California are sinking faster than ever due to excessive groundwater pumping as the state deals with a devastating drought, a NASA report released on Wednesday said. Some areas are experiencing nearly 2 inches (5 cm) of sinking per month, a trend that …
Super Typhoon Soudelor, the most powerful storm so far this year, is generating waves of close to 15 metres as it barrels towards Taiwan. Sustained winds were last calculated at 130 knots (241km/h), with gusts reaching 160 knots (296km/h), according to the Joint Typhoon Warning Centre. "This super typhoon was …
A new study has just been prepared for an upcoming climate meeting of the US Climate Variability and Predictability Program. This group has an annual summit and this year will have a special science session with papers and presentations devoted to the so-called “hiatus”. The “hiatus” has taken many meanings. …
