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.
