Could the warnings be any clearer? Climate tipping points are upon us and adaptation as will as mitigation are key to grappling with global warming

Closing in on Climate Tipping Points: Irreversible Climate Change, Managing the Risk and Learning to Adapt

In the past days and weeks several scientific reports indicate that, even while advocating a 1.5 to 2 C degree rise in average global temperatures over the next century, we may now be at or even passed critical tipping points and heading into a world of irreversible global warming. Earlier this month the Organization for Economic Cooperation and Development (OECD) released…

Melting glaciers across the globe will make a major contribution to sea level rise in the coming century

Melting Glaciers and Sea Level Rise

The massive ice sheets of Antarctica and Greenland have long been considered the major suspect contributors of sea level rise in the coming century. But a study published last month in the journal Nature Geoscience indicates that sea level rise this century may be more of a “death from a thousand cuts” from smaller mountain glaciers and ice caps, particularly those…

The amount of greenhouse gases emitted by even a large and ongoing volcanic eruption is miniscule compared to industrial and automotive carbon emissions caused by human activity. Global warming can, however, help trigger volcanic eruptions by melting the ice that keeps rock from turning to magma.

EarthTalk: Volcanoes and Global Warming

EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine Dear EarthTalk: Is there any link between increased volcanic activity—such as the recent eruptions in Iceland, Alaska and elsewhere—and global warming? – Ellen McAndrew, via e-mail It’s impossible to pin isolated natural phenomena—like an individual volcanic eruption—on global warming, but some researchers…
