One might assume that anything that might reflect sunlight back into space, like bright aircraft contrails, would be good for decreasing the effects of global warming, but a new study predicts that the atmospheric heat trapped by the water vapor in the ‘trails will triple by the middle of theread more

Earlier this year, China and Russia conducted a series of experiments that caused a disturbance high in the atmosphere, aimed at testing ionospheric manipulation technologies for military purposes, according to scientists involved in the experiments. Such experiments advance the understanding of how the ionosphere works, and might allow researchers to learn how to manipulate this crucial layer of the atmosphere to both help facilitate — and possibly disrupt — radio communications.

One of the ways that scientists propose that we tackle the problem of global warming is to actively remove greenhouse gases, such as carbon dioxide, from the atmosphere. To be an effective compliment to reducing our CO2 output from transport and industry, carbon sequestration will have to be done on a massive scale, meaning that the materials used in the process will need to be plentiful. One of those materials, magnesite, readily absorbs CO2, but there are both practical and economic limits keeping industry from mining the mineral in quantities large enough to be effective. However, researchers in Canada have discovered a way to quickly produce the mineral more
