Freshwater ice can melt into scallops and spikes

Ice submerged in liquid water can melt into three different shapes, depending on the water’s temperature.

Satellites have located the world’s methane ‘ultra-emitters’

Plugging leaks from methane ultra-emitters would make a dent in greenhouse gas emissions — and be cost-effective for those countries, scientists say.

Oceans

The past’s extreme ocean heat waves are now the new normal

Marine heat waves that were rare more than a century ago now routinely occur in more than half of global ocean, suggesting we’ve hit a “point of no return.”

Intense drought or flash floods can shock the global economy

Rainfall extremes have powerful impacts on the global economy, affecting the manufacturing and services sectors more than agriculture.

How electric vehicles offered hope as climate challenges grew

Amid daunting climate change challenges, electric vehicles swerved into the spotlight this year.

Vikings may have fled Greenland to escape rising seas

Vikings abandoned Greenland in the 15th century. Lower temperatures, an expanding ice sheet and rising sea levels may have played a role in their departure.

Antarctica’s Thwaites Glacier ice shelf could collapse within five years

The loss of Thwaites’ buttressing ice shelf could hasten the demise of the “Doomsday Glacier” and raise the risk of dramatic sea level rise.
