CO2 never looked this beautiful: NASA show how greenhouse gases swirl the globe [VIDEO]

NASA released a video that helps us visualize where the major CO2 emission hotspots are and how the greenhouse gas travels and swirls around the globe, guided by weather patterns. The  CO2 emissions were mapped using data gathered during May 2005 to June 2007 with 64 times the resolution of a standard climate model,  on a NASA supercomputer at Goddard Space Center in Maryland…

Bill Nye the ‘Science Guy': ‘It’s not a coincidence that the creationists also deny climate change’

Bill Nye

A famous science communicator and TV personality, Bill Nye has served the world a huge favor with his programs, books and talks in which he argues in favor of science. Over the years, however, he’s had to handle all sorts of critical situations like last year’s now famous debate against Ken Han on creationism. Most recently, Nye dropped by CBS This…

Air pollution much more dangerous than climate change for global agriculture

Scientists have long known that climate change has a major negative impact on global agriculture, potentially even threatening global food security. But a new research shows that air pollution is actually much more threatening. Anthropogenic climate change caused 3.5% decrease in potential wheat yield on a country level in India; air pollution caused more than 32% decrease in potential yield. Ozone…

This Globe Trotting geologist will help us better understand Climate Change

Hima Hassenruck-Gudipati (BS '14) on a backpacking trip along the Tour de Mont Blanc, one of the most popular long distance walks in Europe.

Hima Hassenruck-Gudipati graduated this year from Caltech. She majored in mechanical engineering but minored in geology and her main area of interest was seeing how green technology and engineering can help mitigate the effects of climate change. Now, she has embarked on a global quest to understand the past, the present, and the future of climate change. When Caltech wrote this article…

Melting Arctic has Doubled the Risk of Extreme Winters in Europe and Asia

Arctic-sea-ice-Winter-we-007

The most complex computer simulation of its kind to date suggests that melting Arctic ice is significantly contributing to extreme cold weather in the Northern Hemisphere, with last winter’s Polar Vortex that swept the North American east coast serving as an example. Moreover, the analysis suggests that global warming has actually doubled the risk that any given winter will be…

Climate change has many unexpected consequences – as a research has shown yet again. This time, a team of Montana scientists have shown that the tea flavors are changing, mainly as a result of shifting rainfall patterns. This variability can jeopardize the livelihood of tea growers and has significant effects on the end product we drink. Tea is the most…

The Sixth Grand Extinction Will Be ‘Invisible’

The Quaternary period saw the extinctions of numerous predominantly larger, especially megafaunal, species, many of which occurred during the transition from the Pleistocene to the Holocene epoch. Among the main causes hypothesized by paleontologists are natural climate change and overkill by humans. Image: Wikimedia Commons

Life on Earth has so far passed through five distinct crises that threatened to wipe it out, typically referred to as mass extinctions. The direst one was some 252 million years ago when 96 percent of marine species and 70 percent of life on land became extinct following a yet unconfirmed series of cataclysmic events known as the end-Permian extinction. Mass…

Australia’s 2013 Heat Waves linked to Man-made Climate Change, 5 Studies Conclude

GOVERNMENT OF AUSTRALIA

Australia went through two almost unbearable consecutive summers. Of course, Australia is a naturally hot country, but the temperatures were extremely high even for them. Record temperatures were recorded and heat waves swept throughout the entire country. Now, five separate studies published today conclude that the blazing summers can be blamed on man-made climate change. Sizzling Hot The January 2014 southeastern…

World deforestation surprisingly results in net cooling effect

In the 1950s rainforests  covered 14% of the earth’s land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years. It’s believed that deforestation accounts for about 20% of global emissions of CO2, because of the a reduced carbon storage capacity. Yet there may be a hidden side…

A new study concluded that there’s about a 1 in 100,000 chance that the global warming in the past 60 years is not caused by human-released greenhouse gas emissions. It’s much more a debate between TV shows and regular Joes than it is between scientists – you could basically call it a consensus by now, with over 99.83% of all…
