In 1940, after Copenhagen was occupied by Nazi Germany, many of its Jews were saved when Danes and Swedes cooperated to spirit them at night across the narrow strait from the Danish town of Helsingør to the Swedish town of Helsinborg. On the Danish side of the strait, there is now a monument, lit at…
One of the main scientists who convinced world leaders to take note of climate change says that the Copenhagen talks are so flawed, it would be better if they collapse so the process can resume from scratch. James Hansen, director of the Goddard Institute for Space Studies (an Earth Institute affiliate) told The Guardian newspaper,…
In my previous blogs, I have been discussing different ways in which the human right to clean water is violated. I have already discussed how economic scarcity occurs, and this week I will be discussing pollution of water. Pollution issues are largely leading to contamination of the water supplies around the world. There are countless…
We can only marvel at the disarray. Here we are, 17 years after the signing of the UN framework convention on climate change, two years after the decision in Bali to agree a new climate policy, one year after Barack Obama’s election, and days out from the Copenhagen conference. Yet a real global strategy to…
Two broad pieces must be part of any world climate agreement. The one you hear the most about so far is mitigation: cutting emissions of greenhouse gases. The other–perhaps more pressing–is adaptation: measures we must take to adjust agriculture, infrastructure and economies to changes already happening. We do not have to look to the distant…
By Clare Oh Stephen Zebiak, director general of the International Research Institute for Climate and Society (IRI), is in the business of helping societies adapt to changing climate: adjusting farming methods and crops, tackling climate-sensitive diseases such as malaria, and protecting low-lying areas from sea-level rise. Clare Oh of the Columbia University Record talked with…
By Cynthia Rosenzweig At the Copenhagen climate summit, nations must answer a call for action—but local governments may help show the way. Climate change is no longer predicted; it has arrived. A plethora of studies shows that global changes in physical and biological systems are being caused by human-induced warming. Building on the 2007 Intergovernmental…
As the nations of the world prepare to meet in Denmark, there is some well publicized noise being emitted to lower expectations for a climate treaty. The United States and China—the two largest emitters of greenhouse gases, with over 40% of the world’s pollutant load–appear to be at the center of this effort at political…
The Columbia Water Center has spent the last two years pursuing its commitment to research on global water scarcity, in 15 countries on 5 continents across the world. In this age of extensive social media networks, it seems a daunting task to reach all those who have helped and supported us…. So we offer this…
