The next generation of solar cells may employ tiny bits of semiconductor material called quantum dots. These can be turned to quantum wires – made with carbon nanotubes. But things get even better and efficient with superconductors – thus helping power companies to reduce the loss of energy to heat, which is typically about 7 percent.

Many enthusiasts have been promoting the use of industrial hemp for producing bioenergy for a long time now. With its potentially high biomass yield and its suitability to fit into existing crop rotations, hemp could not only complement but exceed other available energy crops.

Scientists recently published a detailed road map to move 139 countries to 100 percent renewable energy by 2050

Humans are passing through a dramatic transformation of the planet's surface due to climate change, the most obvious sign being the rapid melting of Arctic sea ice. And now, imaging revealed a striking new chapter: The Bering Sea, which under normal circumstances should remain frozen-over until May, was almost entirely free of ice in early April.

Today we know that six Neanderthals who lived in what is now France were eaten by their fellow Neanderthals some 100,000 years ago. This is according to gruesome evidence of the cannibalistic event discovered by scientists in a cave in the 1990s. Now, researchers seem to have figured out that Global Warming was the reason for these Neanderthals – including two children – to become victims of cannibalism.

The Lancet Commission detailed some viable solutions against pollution, but also emphasized the need for accountability and responsibility of all the involved parties: citizens and civil societies, governments and officials, but also the importance of vested interests, that may or not interfere with the solutions at hand.

New climate models have shown that if little is done to curb carbon emissions and slow global warming, about 95% of the ice volume of the glaciers in the European Alps will be lost by the end of the century.

As it’s clear that we need to remove CO2 from the atmosphere, there is also the need for viable markets to sell it to. We currently have two such existing markets: seafood and rocks for construction.

Removing atmospheric CO2 is critical because we are currently at a level not seen since before humans evolved. For about 800,000 years, until the Industrial Revolution, global CO2 levels were, on average, 280 ppm. That's the level at which our species and civilization evolved, and the optimal level needed to cement a healthy future for our planet. That level of CO2 should also be the stated goal of the Green New Deal (GND).

In early February, Sen. Ed Markey (D-MA) and Rep. Alexandria Ocasio-Cortez (D-NY) introduced the Green New Deal (GND), a sweeping resolution that addresses the dual challenges of income inequality and climate change, and the first government policy document aimed at curbing climate change as one of its goals.
