How Sea Ice Forms

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about minus 1.8 degrees Celsius (28.8 degrees Fahrenheit). Most Antarctic sea ice occurs annually, meaning it forms in the winter and melts during the summer. Sea ice regulates exchanges of heat, moisture and salinity in the polar oceans. It insulates the relatively warm […]

Antarctic Fish Have Ice In Their Veins

Scientists have revealed that some fish that thrive in the freezing cold waters of the Antarctic actually have ice in their veins. A protein in their system called notothenioids not only keep the fish from freezing to death, but also keeps ice crystals in their veins. Although the ice crystals would melt at temperatures just slightly above freezing, the fish […]

Tropical groundwater resources resilient to climate change

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

Jupiter’s Destructive Path

Earth may owe its existence to the planet Jupiter. New research shows that the giant planet played a key role in the formation of the solar system by barreling through it like a cosmic wrecking ball, destroying existing planets and creating debris that coalesced into new ones, including ours. Astronomers began examining this theory after finding that virtually all of […]

Humans settled, set fire to Madagascar’s forests 1,000 years ago

There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University […]

The big melt: Antarctica’s retreating ice could re-shape Earth

CAPE LEGOUPIL, ANTARCTICA: From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging thousands of feet below to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours […]

New species in the Himalayas

new species in the Himalayas

A bright blue dwarf snakehead fish that can wriggle around on land for up to four days at a time and a snub-nosed monkey that sneezes when it rains: Those are just two of 211 new species found over the past five years in the Eastern Himalayas, the World Wildlife Federation reports. The region, which spans central Nepal, Myanmar, and […]
