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.
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.
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.
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?
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.
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…
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.
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…
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.
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.
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.
