Despite warnings from scientists, rising sea levels still seem little more than a distant, imperceptible threat, a phenomenon whose change is measured in centimeters over decades.
Nowhere is that reflected more than in peninsular Florida, where cities and counties continue to approve hundreds of luxury homes, hotels and condos on exposed barrier islands and slowly receding coastlines.

An international team of scientists discovered a surprisingly strong regional sea-level rise which occurred during the onset of Antarctic glaciation about 34 million years ago, while the global sea-level on average lowered. In an article, published today in Nature Geoscience, scientists of the Royal Netherlands Institute for Sea Research (NIOZ), Utrecht University and TU Delft explain why.

A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid-20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers.
The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes o ... read more >>
SOMETHING odd happened in Texas last week.
But the relief, an answer to desperate prayers, is likely to be short-lived. The drought that has gripped much of Texas since the fall of 2010 shows few signs of abating soon. The latest forecasts say that parched West and South Texas will remain dry, and that the state is likely to see above-average temperatures this spring, increasing evap ... read more >>
Glaciers on the edge of Greenland are pouring at about 50 gigatons of water into the Atlantic every year. That’s about half the volume of Lake Geneva, one of Europe’s largest lake, and enough to account for about 10 percent of annual global sea level rise, according to a new study by Swiss and Danish scientists.
The research, published in Geophysical Research Letters, will help scientists impr ... read more >>
Two wind-driven wildfires erupted in northern Colorado on Friday, prompting the evacuation of about 50 residents and signaling an early start to the wildfire season in the parched Rocky Mountain west.
The larger of the two blazes that prompted the evacuations, the Soldier Canyon Fire, has charred about 800 acres near Lory State Park, Poudre Fire Authority Captain Patrick Love told Reuters.

The river—one of the world’s longest at 4,225 miles (6,800 kilometers)—runs a south-north course from its headwaters in central Africa to the Mediterranean Sea.
From the Ethiopian highlands to the arid deserts of South Sudan, Sudan, and Egypt, the Nile River and its tributaries have shaped the history and fate of the region's diverse peoples. ... read more >>
Scientists say the sea-level rise caused by climate change during the rest of this century will not affect all parts of the world equally, because of the ways sea, land and ice interact.
They say parts of the Pacific are likely to see the highest rise. This region is where many low-lying island countries most vulnerable to sea level rise are already struggling. In the Indian Ocean the Seychell ... read more >>
The melting of sea ice and the resulting rush for resources require effective measures to avoid damage in the Arctic, according to an annual United Nations study of emerging environmental issues that also highlight risks from chemicals and the recent spike in illegal wildlife trade.
A reduction in Arctic summer ice cover has become more intense in recent years, culminating in a record low of 3 ... read more >>
Drought, drought, and more drought seems to be what’s in store for most river basins in the West, including the Colorado, the lifeline for 30 million people .Back in late November, I wrote about how NOAA’s seasonal drought outlook for mid-November to late February indicated the persistence of dryness in most of the Colorado River Basin. Unfortunately, not only did those projections largely pan o ... read more >>
