The key to quieter Atlantic hurricane seasons may be blowing in the wind
Every year, storms over West Africa disturb millions of tons of dust and strong winds carry those particles into the skies over the Atlantic. According to a recent study led by University of Wisconsin–Madison atmospheric scientists, this dust from Africa directly affects ocean temperature, a key ingredient in Atlantic hurricane development.

UW-Madison joins largest climate change teach-in in U.S. history
On Jan. 30 and 31, the University of Wisconsin–Madison will participate in Focus the Nation, an unprecedented teach-in on global warming solutions with the aim of preparing millions of students to become leaders in responding to the challenge. Read More
New Antarctica research season kicks off
The approach of winter in the northern hemisphere means that summer is coming to Antarctica - still bitterly cold, but just warm enough to let scientists make progress on ongoing studies. A number of UW–Madison researchers are awaiting the call. Read More
Recipe for a storm: The ingredients for more powerful Atlantic hurricanes
As the world warms, the interaction between the Atlantic Ocean and atmosphere may be the recipe for stronger, more frequent hurricanes. Read More
Post-Kyoto environmental discussion to take place at UW–Madison
This December in Bali, new international talks will be launched to determine the successor of the Kyoto Protocol on Climate Change. The science has spoken. We know the problem is real, but how do we move forward with a solution? Read More
Health toll of climate change seen as ethical crisis
The public health costs of global climate change are likely to be the greatest in those parts of the world that have contributed least to the problem, posing a significant ethical dilemma for the developed world, according to a new study. Read More
Illustration: The ethical dimensions of global climate change
The two world maps schematically represent the contribution of different nations to global warming, as measured in atmospheric carbon output (top) and… Read More
Wildfire drives carbon levels in northern forests
Far removed from streams of gas-thirsty cars and pollution-belching factories lies another key player in global climate change. Circling the northern hemisphere, the conifer-dominated boreal forests - one of the largest ecosystems on earth - act as a vast natural regulator of atmospheric carbon levels. Read More
UW-Madison faculty contributed to global warming reports that led to Gore’s Nobel
University of Wisconsin–Madison faculty made significant contributions in developing the reports on the implications of global warming that led today (Oct. 12) to the awarding of the 2007 Nobel Peace Prize to Vice President Al Gore and the United Nations' Intergovernmental Panel on Climate Change (IPCC).

Hungry insects leave clues to impacts of climate change
Harshaw, Wis. — A boardwalk beckons into the stand of trees, pleasantly cool on a hot summer morning — where it becomes immediately clear… Read More
New certificate prepares students for global change
Graduate students intrigued by large-scale environmental challenges like climate change will have a new opportunity this fall at the University of Wisconsin–Madison. Read More
Global warming forecasts creation, loss of climate zones
A new global warming study predicts that many current climate zones will vanish entirely by the year 2100, replaced by climates unknown in today's world. Read More
New evidence that global warming fuels stronger Atlantic hurricanes
Atmospheric scientists have uncovered fresh evidence to support the hotly debated theory that global warming has contributed to the emergence of stronger hurricanes in the Atlantic Ocean. Read More
Researcher seeks ‘missing piece’ in climate change models
To most people, soil is just dirt. But to microbiologists, it is a veritable zoo of bacteria, fungi and nematodes. It's also a vast carbon dioxide factory. As these microorganisms consume carbon-based materials found in soil, they release carbon dioxide gas into the atmosphere as a normal part of their metabolism. Read More
Supercomputer to power climate change study
Climate researchers at the University of Wisconsin–Madison have been given unprecedented access to one of the world's most powerful supercomputers to better understand the causes and consequences of abrupt climate change. Read More
Third World bears brunt of global warming impacts
A team of health and climate scientists at UW–Madison and the World Health Organization report in the journal Nature that the growing health impacts of climate change affect different regions in markedly different ways. Ironically, the places that have contributed the least to warming the Earth are the most vulnerable to the death and disease higher temperatures can bring. Read More
Climate change to bring a wave of new health risks
Climate change will not only bring about a warmer world, it is also very likely to set the stage for an unhealthier one. Read More
150-year global ice record reveals major warming trend
From sources as diverse as newspaper archives, transportation ledgers and religious observances, scientists have amassed lake and river ice records spanning the Northern Hemisphere that show a steady 150-year warming trend. Read More
