When the Moon’s shadow races across the continental United States on 21 August, researchers will be waiting — in planes, on mountaintops and at other carefully chosen vantage points along the roughly 110-kilometre-wide path of totality. Thanks to the sheer number of observers, solar physicists hope to learn more from this latest total solar eclipse than from any previous such event, and to use that knowledge to develop tools for next time.

With the first six months of 2017 in the books, average global surface temperatures so far this year are 0.94°C above the 1950–1980 average, according to NASA.

Arctic winter warming events, winter days when temperatures peak above minus 10 degrees Celsius, are becoming more frequent and lasting longer than they did three decades ago, a new research has fo

Agricultural systems for space have been discussed since the works of Tsiolkovsky in the early 20th century. Central to the concept is the use of photosynthetic organisms and light to generate oxygen and food. Research in the area started in 1950s and 60s through the works of Jack Myers and others, who studied algae for O2 production and CO2 removal for the US Air Force and the National Aeronautics and Space Administration (NASA).

This recently released NASA simulation of the global atmospheric carbon dioxide (CO2) cycle offers a powerful counterpoint to the Trump team’s push to marginalize climate change research. The visualization conveys the message that rising concentration of atmospheric carbon dioxide on Earth will produce thermostat-like effects. It also seeks answers to questions such as how land and ocean absorbs the greenhouse gas and what will happen when it reaches a point of saturation. It shows 50 percent of human-made emissions staying in the atmosphere, while 25 percent goes to the oceans with the other 25 percent being absorbed by land vegetation.

A spate of extreme warmth in the Arctic over the past two months has startled scientists, who warn that the high temperatures may lead to record-low ice coverage next summer and even more warming i
