Antarctica is melting all over

No ice build-up in East Antarctica, new study says Staff Report Despite some suggestions that increased has bolstered the vast East Antarctic ice sheet, it appears the frozen continent is still shedding ice and has been a net contributor to sea level rise since at least 2003. There’s been little doubt during the last decade … Continue reading Antarctica is melting all over

Ocean layering around Antarctica could signal major meltdown

Study warns of 10-foot sea level rise Staff Report As scientists learn more about the dynamics of the ocean around Antarctica, they’ve discovered a climate warming signal. Distinct layers of water, marked by temperature boundaries, are forming right now, leading to conditions similar to about 14,000 years ago, when Antarctic ice sheets melted rapidly, raising … Continue reading Ocean layering around Antarctica could signal major meltdown

How will Antarctica respond to global warming?

Long-term studies show potential impacts of climate change Staff Report A new set of scientific reports highlights the value of long-term observations in relatively undisturbed ecosystems and also offers a preview of how global warming may change Antarctica in coming decades. The research shows that a period of unusual warmth in 2001 and 2002, caused … Continue reading How will Antarctica respond to global warming?

What’s the tipping point for Antarctica’s ice sheets?

New study suggests rapid meltdown during post-ice age warming Staff Report After taking a close look at rocks from West Antarctica’s dramatic Ellsworth Mountains, climate researchers say there’s a chance that ice sheets in the region could melt quickly as the planet warms, potentially causing sea level to rise by  six to eight feet. The … Continue reading What’s the tipping point for Antarctica’s ice sheets?

Warming oceans to aid spread of invasive species in Antarctica

Kelp rafts seen pathways for non-native worms, snails Staff Report Parts of Antarctica could soon face an invasion by exotic species floating southward on kelp rafts, Australian researchers found in a new study published in the journal Ecography. While the Antarctic circumpolar current has long formed a barrier to invasive species, the research found that … Continue reading Warming oceans to aid spread of invasive species in Antarctica

Climate: Increased Antarctica snowfall no buffer to sea level rise

New research suggests that Antarctica’s contribution to sea level rise over the next few decades has been underestimated By Bob Berwyn When it comes to the question of how much sea levels will rise in the global warming era, Antarctica is the big, frozen, enchilada. Just a partial meltdown of the ice shelves along the … Continue reading Climate: Increased Antarctica snowfall no buffer to sea level rise

Antarctica snowfall may be outpacing glacier melt

Still a few decades from meltdown Staff Report A new analysis of satellite data suggest that snow accumulation in Antarctica is outpacing the meltdown of glaciers on the frozen continent, at least for now. The findings of the the new NASA research differ from other recent studies, which have found that, overall, Antarctica is losing … Continue reading Antarctica snowfall may be outpacing glacier melt

Environment: Some countries only paying lip service to Antarctica conservation

Legal analysis finds some countries are abusing an international conservation treaty to justify more Southern Ocean fishing Staff Report Efforts to set aside protected ocean areas around Antarctica are faltering because some countries are willfully misinterpreting a legal treaty governing the use of resources in the region, according to a new analysis published in the journal … Continue reading Environment: Some countries only paying lip service to Antarctica conservation

Burning the rest of Earth’s fossil fuels would completely melt Antarctica

New study looks far into the climate future Staff Report FRISCO — Using the rest of Earth’s fossil fuels is not an option — at least not if humankind wants to avoid 150 to 200 feet of sea level rise, a team of prominent scientists said after trying to project the fate of the world’s … Continue reading Burning the rest of Earth’s fossil fuels would completely melt Antarctica

Morning photo: What next for Antarctica?

Big changes ahead for the frozen continent FRISCO —I often write about the environmental changes expected in Antarctica as the world heats up under its man-made blanket of heat-trapping greenhouse gases because those changes will have huge implications for the rest of the planet. It’s not just the melting ice and rising sea level. When … Continue reading Morning photo: What next for Antarctica?
