Climate conflict: Sea level vs. surface temp

PENN STATE (US) — Engineering our way out of global climate warming may not be as easy as simply reducing the incoming solar energy, a research team concludes. (more…)

Salt marshes predict sea level rise

PENN STATE (US) — Scientists are using a 2,000-year history to refine models used to gauge climate-change induced sea level rise, which, during the past century, rose at a faster rate than ever before. (more…)

Map surfaces ice sheet’s underbelly

U. TEXAS-AUSTIN (US) — A high-resolution map uses ice-penetrating radar to reveal some of the largest fjords on Earth at the Aurora Subglacial Basin in East Antarctica. (more…)

Seaports unprepared for climate change

STANFORD (US) — Seaport officials are unsure how best to protect their facilities from rising sea levels and more frequent Katrina-magnitude storms, two possible consequences of global warming. (more…)

Erratic ice sheet raising sea levels

U. LEEDS (UK) — At some point in time, the Antarctic ice sheet was extensive enough and thick enough to move boulders the size of a small family car. (more…)

More melting may slow glacier flow

U. LEEDS (UK) — Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers. (more…)

Greenhouse gas causing Indian Ocean to rise

U. COLORADO (US)—Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra, and Java, appear to be at least partly a result of human-induced increases of atmospheric greenhouse gases. (more…)

Massive ice loss has sea levels rising

U. LEEDS (UK)—The loss of floating ice in the polar oceans each year—equivalent to 1.5 million Titanic-size icebergs—is causing sea levels to rise. (more…)

Greenland melt spreads to both coasts

U. COLORADO (US)—Ice loss from the Greenland ice sheet, which has been increasing during the past decade over its southern region, is now making an upward climb on its northwest coast as well. (more…)

Shifting debate on sea level models

U. IOWA (US)—New findings about the close link between changes in sea level and Earth’s climate challenge theories about the rates of ice accumulation and melting during the Quaternary Period—the time interval ranging from 2.6 million years ago to the present. (more…)

Climate ‘tipping points’ prove unpredictable

UC DAVIS (US)—Sudden shifts in Earth’s natural systems may be harder to foresee than previously thought, worrying scientists trying to identify dramatic global climate changes before they occur. (more…)

Little global warming goes a long way

PRINCETON (US)—The planet’s polar ice sheets are vulnerable to large-scale melting even under moderate global warming scenarios. Such melting would lead to a large and relatively rapid rise in global sea level, submerging many coastal areas. (more…)

Atlantic Coast sea level rises at faster pace

U. PENN (US)—Sea level along the Atlantic Coast is rising faster now than at any time in the past 4,000 years. (more…)

Watching glaciers slide—in a freezer

IOWA STATE (US)—A walk-in freezer in Iowa may help scientists understand how glaciers react to climate change and contribute to rising sea levels. (more…)

North Carolina sea level rises at faster pace

U. PENN (US)—An international team of environmental scientists has shown that sea-level rise, at least in North Carolina, is accelerating. The increase during the 20th century is three times higher than the rate of sea-level rise during the last 500 years. (more…)

Arctic heat bucks long-term trend

Since the Earth is still moving away from the sun—it’s about 0.6 million miles farther during the Northern Hemisphere summer solstice than it was in 1 B.C.—it appears greenhouse gases began “overriding” the natural cooling of Earth in the middle of the last century, explains study coauthor Gifford Miller of CU-Boulder’s Institute for Arctic and Alpine Research. “We expect the Arctic will continue to warm in the coming decades, increasing land-based ice loss and triggering global increases in sea-level rise.”
