We know ice is melting on the Earth’s poles.

he oceans are losing oxygen. Numerous studies based on direct measurements in recent years have shown this. Since water can dissolve less gas as temperatures rise, these results were not surprising.

In the right conditions, airplane contrails can linger in the sky as contrail cirrus – ice clouds that can trap heat inside the Earth’s atmosphere.

The heat wave arrived early this spring — a shroud of temperate air, sweeping in during early June, which enveloped the Northern Hemisphere’s biggest ice sheet in a stifling hug.
