New devices could help turn atmospheric CO2 into useful supplies

These electrochemical cells might also one day make deep-space missions easier BY MARIA TEMMING 6:00AM, OCTOBER 30, 2018 New chemical-recycling devices might help combat climate change by making good use of heat-trapping gas produced by burning fossil fuels. These electrochemical cells convert carbon monoxide into useful compounds much more efficiently than their predecessors, researchers report online October 25 in Joule. If combined with existing technology that harvests … Continue reading New devices could help turn atmospheric CO2 into useful supplies

Why does India’s air look different from space?

There is something very distinct about the air over India and the surrounding countries in South Asia. It is the presence of formaldehyde – a colourless gas that is naturally released by vegetation but also from a number of polluting activities. The elevated concentrations have been observed by Europe’s new Sentinel-5P satellite, which was launched last October to track air quality worldwide. It is information … Continue reading Why does India’s air look different from space?

Around 1.4 Billion Years Ago One Day Only Consisted Of 18 Hours

New Study Proves that Days Were Shorter in The Past. According to a new study, Moon is constantly getting away from Earth, and its distance has a significant effect on the duration of hours that make up for a full day on the Earth. Among other different reasons, Moon’s existence and its distance from Earth make our planet an ideal place where biological life can … Continue reading Around 1.4 Billion Years Ago One Day Only Consisted Of 18 Hours

Air pollution to blame for traffic accidents: study

| 10/04/2016 London: Air pollution may be responsible for hundreds of car accidents a year, as toxic air may impair driver fitness, a new UK study has found. Researchers from the London School of Economics divided the UK into a grid of 32 areas each covering about 7,700 square kilometres and mapped accidents to the level of air pollution between 2009 and 2014. They found … Continue reading Air pollution to blame for traffic accidents: study

Elephant seals to measure changing ocean currents

| 08/31/2016 Scientists have used a group of elephant seals to observe changes in the circulation of the world’s oceans reveals a recent research.The international researchers led by the University of Tasmania’s Dr. Guy Williams, used sensors attached to 20 elephant seals to measure water temperature and salinity in the Antarctica, Xinhua news agency reported. The research showed how “bottom water” – a dense type … Continue reading Elephant seals to measure changing ocean currents

UK air quality shows little improvement over past 20 years, says study

| 08/30/2016 There has been little improvement in air quality over the past 20 years as transport planners focus on preventing road deaths, according to a study. Two university academics set out to try to understand why there has been little improvement in air pollution concentrations from road transport since the UK signed up to international air quality standards in 1995, as part of the … Continue reading UK air quality shows little improvement over past 20 years, says study

Global warming is melting the Greenland Ice Sheet, fast

| 08/27/2016 A new study measures the loss of ice from one of world’s largest ice sheets. They find an ice loss that has accelerated in the past few years, and their measurements confirm prior estimates. As humans emit heat-trapping gases, we expect to see changes to the Earth. One obvious change to be on the lookout for is melting ice. This includes ice atop … Continue reading Global warming is melting the Greenland Ice Sheet, fast

India ranked 77 in disaster risk index of the world

| 27/08/2016 While Bangladesh is among the top five countries at risk of disaster, India ranks 77 on the World Risk Index – marginally better positioned than Pakistan which is placed at 72. The index is part of the World Risk Report 2016 released on Thursday by the United Nations University Institute for Environment and Human Security (UNU-EHS) and Bundnis Entwicklung Hilft in cooperation with … Continue reading India ranked 77 in disaster risk index of the world

Human-induced climate change began earlier than previously though

| 08/25/2016 Continents and oceans in the northern hemisphere began to warm with industrial-era fossil fuel emissions nearly 200 years ago, pushing back the origins of human induced climate change to the mid-19th century. The first signs of warming from the rise in greenhouse gases which came hand-in-hand with the Industrial Revolution appear as early as 1830 in the tropical oceans and the Arctic, meaning … Continue reading Human-induced climate change began earlier than previously though

Study measures methane discharge from Arctic permafrost

| 08/25/2016 The project, led by UAF researcher Katey Walter Anthony, studied lakes in Alaska, Canada, Sweden and Siberia where permafrost thaw surrounding lakes led to lake shoreline expansion during the past 60 years. Using historical aerial photo analysis, soil and methane sampling, and radiocarbon dating, the project quantified for the first time the strength of the present-day permafrost carbon feedback to climate warming. Although … Continue reading Study measures methane discharge from Arctic permafrost
