How airplane contrails are helping make the planet warmer

New research shows that condensation trails from aircraft exhaust are playing a significant role in global warming. Experts are concerned that efforts to change aviation engine design to reduce CO2 emissions could actually create more contrails and raise daily temperatures even more.

As Ocean Temperatures Rise, Corals Are Steadily Moving Poleward

Rising ocean temperatures are increasingly causing coral reefs to shift away from the equator into more temperate waters. Over the past 40 years, the number of young corals has declined by 85 percent on tropical reefs, while at the same time doubling in cooler regions, according to a recent study.

These sled dogs aren’t walking on water, but something fishy is going on

Each year in June, just before all the sea ice has melted, climate scientists at the Danish Meteorological Institute head out by dog sled onto the Greenland sea ice to collect their instruments. Typically the dogs walk on ice for this task, but because of warming temperatures, this year the dogs were splashing in ankle-deep water.

As Water Scarcity Increases, Desalination Plants Are on the Rise

After decades of slow progress, desalination is increasingly being used to provide drinking water around the globe. Costs for processing salt water for drinking water have dropped, but it remains an expensive option and one that creates environmental problems that must be addressed.

Near-record ‘dead zone’ predicted in Gulf of Mexico

Scientists are predicting a near-record Gulf of Mexico “dead zone” where the water holds too little oxygen to sustain marine life.

Scientists start the clock on human impact

Though it’s clear we’re currently living in it, scientists have long debated when the Anthropocene, the epoch of human dominance over the planet, first began. The Anthropocene Working Group (AWG), a panel of scientists, recently voted to official recognize the epoch and suggested starting it in the middle of the 20th century
