Traffic Woes – September 6, 2023

Traffic. We’ve all been in it. But why does it happen? Aside from construction and accidents causing it, doesn’t it seem like sometimes traffic happens for no good reason? Indeed, ‘phantom’ or ‘shockwave’ traffic jams, caused by a chain reaction of slowing down, do...

Antarctic Sea Ice Decline – August 30, 2023

Antarctic Sea Ice Decline – August 30, 2023

For decades, Antarctic sea ice seemed to be immune to climate change – growing in places and staying steady in others – while Arctic sea ice has seen serious decline. But this came to an end in 2016, with significant decreases to the sea ice. In fact, 2017 has a...
