The Population Debate Is Screwed Up

Debaters on population usually take two sides: either they see it as a huge problem facing humanity, or that it's a non-issue. They're both wrong. This polarized debate has generated lots of heat and little light over the last half-century. According to the combatants, population growth is either the biggest problem facing humanity, or it is a complete non-issue. [...more]

Opportunity for 2 degrees lost

Quietly in public, loudly in private, climate scientists everywhere are saying the same thing: it's over. The years in which more than 2degrees of global warming could have been prevented have passed, the opportunities squandered by denial and delay. On current trajectories we'll be lucky to get away with 4degrees. [...more]

Buying local isn’t always better for the environment

Shopping locally may not be as good for the environment as having food delivered, according to new research by the University of Exeter (UK). Published in the journal Food Policy, the study shows that, on average, lower carbon emissions result from delivering a vegetable box than making a trip to a local farm shop. [...more]

Dramatic Expansion Of Dead Zones In The Oceans

Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. In shallow coastal regions, these zones can be caused by runoff of excess fertilizers from farming. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean by a factor of 10 or more. [...more]

Climate Change Threat: Developing Countries Lack Means to Acquire More Efficient Technologies

Contrary to earlier projections, few developing countries will be able to afford more efficient technologies to reduce greenhouse gas emissions in the next few decades, new research concludes. The study, by researchers at the National Center for Atmospheric Research (NCAR) and the University of Colorado, warns that continuing economic and technological disparities will make it more difficult than anticipated to reduce greenhouse gas emissions, and it underscores the challenges that poorer nations face in trying to adapt to global warming.

1988 and 2008: Climate Change Turning Points

Exactly 20 years have passed since Dr. James E. Hansen of NASA first testified to Congress on June 23, 1988 that global temperatures had risen beyond the range of natural variability. Waiting another 20 years before taking decisive action is not an option. [...more]

HSUS Fact Sheet: Animal Agriculture and Climate Change

Abstract According to a 2006 report by the Food and Agriculture Organization (FAO) of the United Nations, the animal agriculture sector emits more greenhouse gases than cars and SUVs. Greenhouse Gas Emissions (GHGs) The animal agriculture sector is responsible for 18% of greenhouse gas emissions, measured in carbon dioxide (CO2) equivalent, higher than the share [...] [...more]

Indigenous peoples hardest hit by climate change describe impacts

Indigenous peoples have contributed the least to world greenhouse gas emissions and have the smallest ecological footprints on Earth. Yet they suffer the worst impacts not only of climate change, but also from some of the international mitigation measures being taken, according to organizers of a United Nations University co-hosted meeting April 3 in Darwin, Australia.
