The North American Heatwave Shows We Need To Know How Climate Change Will Change Our Weather

The North American Heatwave Shows We Need To Know How Climate Change Will Change Our Weather Share Published 4 hours ago: July 5, 2021 at 10:00 am   Eight days ago, it rained over the western Pacific Ocean near Japan. There was nothing especially remarkable about this rain event, yet it made big waves twice. First, it disturbed the atmosphere in just the right way to set off an undulation in the jet stream – a river of very strong winds in the upper atmosphere – that atmospheric scientists call a Rossby wave (or a planetary wave). Then the wave was guided eastwards by the jet stream towards North America.

Lakes Under Mars South Pole May Not Be Real

Lakes under Mars south pole may not be real Adv. New York, July 4 (IANS) Subsurface lakes found under Mars’ south pole, using data from the European Space Agency’s Mars Express orbiter, may not really be lakes at all, argue researchers. Two research teams in 2018, working on data from the Mars Express orbiter announced a surprising discovery: Signals from a radar instrument reflected off the red planet’s south pole appeared to reveal a liquid subsurface lake. However, a team of scientists at NASA and Arizona State University (ASU) found dozens of similar radar reflections around the south pole after analysing a broader set of Mars Express data.
