Chinese President Hu Jintao on Tuesday promised to put a "notable" brake on the country's rapidly rising carbon emissions, but dashed hopes he would unveil a hard target to kickstart stalled climate talks. The leader of the world's biggest emitter told a U.N. summit that China would pledge to cut "carbon intensity," or the amount of carbon dioxide produced for each dollar of economic output, over the decade to 2020.

Floodgates Might Not Save Venice

The construction of mobile floodgates aims to safeguard the 1,300-year-old island city of Venice. It's an ambitious engineering project, but some scientists say it may not be sufficient to protect Venice from rising sea levels due to climate change. Venice rose from mudflats in the middle of a lagoon which forms the largest wetland in the Mediterranean. One of the world's most endangered cities, it has been subject to increasing flooding due to sinking land — but also to rising sea levels.

River Deltas Sinking

A new study led by the University of Colorado at Boulder indicates most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk.

Arctic Geese Skip Migration

In the Fall of 2007, tens of thousands of small arctic geese called Pacific brant (Branta bernicla nigricans) decided not to go south for the winter. For these long-haul migratory birds, it was a dramatic choice -- they usually spend the cold months munching their favorite eel grass in the waters off Mexico's Baja peninsula.

Global warming could actually chill down North America within just a few decades, according to a new study that says a sudden cooling event gripped the region about 8,300 years ago.

New Carbon Dioxide Data Helps Unlock The Secrets Of Antarctic Formation

The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

Summer Temperatures Lower Than Normal Over Most of US

Global warming doesn’t necessarily mean that temperatures are rising every year, everywhere. Superimposed on global trends are local and regional climate effects that may differ from global trends. For example, the average June-August 2009 summer temperature for the contiguous United States was below average – the 34th coolest on record, according to a preliminary analysis by NOAA’s National Climatic Data Center in Asheville, N.C. August was also below the long-term average. The analysis is based on records dating back to 1895.

India Could Halve Emissions Growth, at a Cost
September 10, 2009 07:32 AM - Anna da Costa, Worldwatch Institute

Growth in India's carbon emissions could be nearly halved by the year 2030 through the use of known practices and technologies, according to a new report from McKinsey & Company. Through a "step-change in...efforts to lower emissions," India's carbon output could grow from 1.6 billion tons in 2005 to only 2.8 billion tons in 2030 as the country's population expands and its economy develops, the report said. This is down from a previously projected 5-6 billion tons for 2030.
