Vegetable juice ice-melt?  Ice-free pavement? "Smart snowplows"?  

Cold-climate researchers at Washington State University are clearing the road with 'green' alternatives to salt.

In the 1960s, there was talk of a dystopian future where the masses starved because the ghost of Malthus came home to roost and the world could no longer feed its people.

Instead, Norm Borlaug and science ushered in a "Green Revolution" and countries that embrace science, like America, have reduced environmental strain while producing more food than ever dreamed possible. One other interesting effect the boost in agriculture has had: changing the amplitude of atmospheric carbon dioxide by about 15 percent during the last five decades. 

A new atmospheric model called VEGAS estimates that on average, the amplitude of the seasonal oscillation of carbon dioxide in the atmosphere is increasing at the rate of 0.3 percent every year. 

The Earth has a magnetic field that functions as an in-built force-field against galactic cosmic rays, particles from space which prompt a chain-reaction of events in thunderclouds that trigger lightning bolts. 

The only thing more powerful than our magnetic field is that of the Sun, and it may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing more energetic particles to enter the upper atmosphere. Over a five year period, the UK experienced around 50% more lightning strikes and researchers found that correlates to when the Earth's magnetic field was skewed by the Sun's own magnetic field.

Each year, the biosphere balances its atmospheric budget: The carbon dioxide absorbed by plants in the spring and summer as they convert solar energy into food is released back to the atmosphere in autumn and winter. Levels of the greenhouse gas fall and rise with growth and harvesting.

Iowa corn farmers have a lot of clout during the political cycle in America. Former US Vice-President Al Gore even sided with environmentalists and embraced ethanol - which all of science said was a bad idea - and later acknowledged it was just to appeal to Iowa. They help pick presidents and now it turns out that their 2.2 billion bushels of corn are helping to save the planet too.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Aqua satellite captured a visible picture of Tropical Storm Adjali on Nov. 19th at 9:05 UTC (1:05 A.M. Pacific) curving to the southwest on its trek through the Southern Indian Ocean.

The MODIS image showed that the storm began curving to the southwest, and despite slight weakening, thunderstorms circled around the low-level center.
