The Bottom Line Expert Opinion: Renewable Energy

...carbon trading my reduce carbon emissions, massive government intervention is needed to positively fight climate change. Naomi Oreskes examines this issue in her article “Without Government, the Marketplace Will Not Solve Climate Change”. Is “green business” simply another way for corporations to put their private profits over the public good? This raises...

Sea level rise in London, UK

...Carbon Brief, 2014). From the evidence of the London Bridge high water mark, we know that the level has risen since 1780 by over 1.5 metres (Carbon Brief, 2014). Alongside ice melt increasing seawater volume other factors have important impacts on the changing sea level in London. Around 11,500 years ago ice sheets covering the north of the British Isles began to retreat....

Why we’re mapping a million trees and more!

...carbon dioxide from the atmosphere as they grow. A recent study [1] found that a global tree planting effort aimed at increasing tree cover by 0.9 billion hectares would help to remove two-thirds of all human-produced carbon dioxide. But amid the clamour for more trees, for the many people involved in looking after trees and woodlands the over-riding concern is that we...

A new mission to the icy moons of Jupiter

...carbonates – and now I’m moving on to look at organic (compounds that contain carbon) materials. The Cassini mission in 2008 detected some very simple organic compounds on Enceladus. Starting with them, I’m trying to understand what more complex compounds might be created in the temperature and pressure conditions of the ocean floor of Enceladus. Specifically, I’m...

Europa: Jupiter’s ocean world

...carbon dioxide on the moon’s ice surface, within a region of chaos terrain. This carbon dioxide is proposed to have originated from the ocean beneath. Carbon is one of the bioessential elements for life, making astrobiologists even more excited to learn more about Europa. In the coming years, data returned from ESA’s JUICE and NASA’s Europa Clipper missions will be...

The ocean of Jupiter’s moon Europa

...carbon dioxide ice, but salts such as magnesium sulfate, magnesium chloride, sodium carbonate and sodium chloride (common salt) have also been detected. Assuming these salts and the ice crust formed by freezing of the underlying ocean, this would suggest that magnesium, sulfur, sodium, carbon and chlorine are all present in Europa’s ocean. However, it is unclear from...

Matt Ridley - Stories of Change

...carbon dioxide levels, looked at the Jani equation for how much warming this was likely to produce, and reported it straight, as it were, as a very alarming prospect. I became a little more sceptical in the nineties when I began to look into the science a bit more closely, but then I kind of drifted off and went off and wrote about genes for a number of years and didn’t...

Does it snow on Mars?

...carbon dioxide from the atmosphere. The new study, published in Nature Geoscience, has found a way in which tiny specks of water-ice could travel down to the ground without this strange frozen carbon dioxide coat. If correct, this would mean genuine snow on Mars – just like that on Earth. The team used measurements from two orbiting spacecraft (the Mars Global Surveyor...
