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 …
Last year wasn't just the Earth's hottest year on record _ it left a century of high temperature marks in the dust. The National Oceanic Atmospheric Administration and Nasa announced on Wednesday that 2015 was by far the hottest year in 136 years of record keeping. NOAA said 2015's temperature …
Last year’s global average temperature was the hottest ever by the widest margin on record, two U.S. government agencies said on Wednesday, adding to pressure for deep greenhouse gas emissions cuts scientists say are needed to arrest warming that is disrupting the global climate. Data from U.S. space agency NASA …
It’s official: 2015 was the hottest year on record. Global data show that a powerful El Niño, marked by warmer waters in the tropical Pacific Ocean, helped to drive atmospheric temperatures well past 2014's record highs. Some researchers suggest that broader Pacific trends could spell even more dramatic temperature increases …
A new green-related technologies developed and refined by NASA's aeronautics researchers during the past six years can help commercial airlines save more than $250 billion dollars. These new technologies, developed under the purview of NASA's Environmentally Responsible Aviation (ERA) project, could cut airline fuel use in half, pollution by 75 …
The US space agency Nasa has warned that the effects of the current El Nino weather phenomenon could be as bad as those of 1998, the strongest on record. That El Nino played havoc with world weather systems and was blamed for several extreme weather events. The current El Nino …
A US science satellite slated to launch to Mars in March has been grounded due to a leak in a key research instrument, NASA said on Tuesday, creating uncertainty about the future of a widely anticipated effort to study the interior of the planet. The spacecraft, known as InSight, was …
BHUBANESWAR: To study the biological and geographic parameters of Chilika lagoon and its basin eco-system, the Space Application Centre of ISRO with support from NASA is all set to carry out a hyperspectral study next week, a first of its kind in India. A special aircraft will be flown in …
NEW DELHI: Freshwater lakes across the world are rapidly warming due to changing climate change, a new study supported by NASA has found. This could have serious impact on freshwater supplies and ecosystems. The study used satellite temperature data and long-term ground measurements to monitor 235 lakes, representing more than …
Climate change is rapidly warming lakes around the world, threatening freshwater supplies and ecosystems, new data has revealed. A new Nasa and National Science Foundation-funded study looked at lakes totalling more than half of the world's freshwater supply. Using more than 25 years of satellite temperature data and ground measurements …
WASHINGTON -- India, China and the Middle East, with their fast-growing economies and expanding industry, have seen growing air pollution, according to NASA scientists who tracked the trends over the last decade in various regions and 195 cities around the globe. According to the findings, US, Europe and Japan have …
As Delhi mulls if measures like odd-even car days would help it breathe cleaner air when its neighbours continue to pollute, the National Green Tribunal on Thursday reiterated its order banning straw burning in Delhi NCR and adjoining farming states while suggesting various supporting and coercive measures for farmers to …
Scientists from the United States, Japan, and China are racing to perfect satellite technology that could one day measure greenhouse gas emissions from space, potentially transforming the winner into the world's first climate cop. Monitoring a single country's net emissions from above could not only become an important tool to …
Rising accidents involving merchant ships leading to oil spills in Indian waters is a growing concern that needs to be addressed legally and India’s efforts to ratify the Bunker Convention is a step in that direction. On June 22, 2015, merchant ship Jindal Kamakshi with 20 crew members onboard issued …
NEW DELHI: After a neck-and-neck race with Beijing over the past few winters, Delhi may soon find itself without a rival for the 'most-polluted-city' crown. The Chinese city is doing its best to fall behind although, as happened last week, it sometimes nudges ahead with a wind-aided spurt. A recent …
In October and November, farmers in Punjab and Haryana burn their fields to cheaply clear paddy stubble, raising PM2.5 levels in neighbouring Delhi Since September 2015, an ecological and public health disaster has been unfolding in Indonesia, as fires burn out of control. Such fires spread a haze over the …
The sun can erupt with flares more energetic than 30 billion times the yield of all nuclear weapons ever detonated. The energetic particles released by solar flares tunnel a path through our inner solar system with speeds regularly exceeding 6 million kph. If the Earth is unfortunate enough to sweep …
AHMEDABAD: Scientists from NASA and ISRO would be part of a special outreach programme organized at Gujarat Science City on Monday where the experts would talk about a joint mission Nasa and Isro Synthetic Aperture Radar (NISAR) along with satellites for disaster response, India-US space collaboration, climate change observations in …
NEW DELHI: A startling new report by Nasa scientists suggests that the Antarctic ice sheet may actually be expanding, growing every year, despite a warming globe! This is in direct conflict to the prevailing notions, which suggested that the ice was melting fast as global warming and climate change was …
MIAMI: Melting ice in West Antarctica is a major concern for global sea levels, and a key area may already be unstable enough to unleash three meters of ocean rise, scientists said Monday. The study follows research out last year, led by NASA glaciologist Eric Rignot, warning that ice in …
Uncontrolled burning of paddy stubbles by Punjab farmers appears to be again putting the health of residents in the National Capital Region at risk, with Delhi's air quality falling sharply in the past two days even as farm fires peak in Punjab. Since Saturday, Delhi's air quality index has dramatically …
