Climate change ‘to make Atlantic hurricanes rarer’
Increasing frequency of storms in past 25 years
may not continue, although average severity may
grow.
Hurricanes may become rarer in the Atlantic
throughout the 21st century if the world
continues to warm, suggests a new study.

“… and due to the interactions of nitrogen and
carbon, makes the challenge of providing food and
energy to the world’s peoples without harming the
global environment a tremendous challenge,”….

Excessive Reactive Nitrogen in Environment Alarms Environmental Scientists
ScienceDaily (May 18, 2008) – While human-caused
global climate change has long been a concern for
environmental scientists and is a well-known
public policy issue, the problem of excessive
reactive nitrogen in the environment is
little-known beyond a growing circle of
environmental scientists who study how the
element cycles through the environment and
negatively alters local and global ecosystems and
potentially harms human health.

An Epidemic of Extinctions: Decimation of Life on Earth
The world’s species are declining at a rate “unprecedented since the extinction of the dinosaurs”, a census of the animal kingdom has revealed. The Living Planet Index out today shows the devastating impact of humanity as biodiversity has plummeted by almost a third in the 35 years to 2005.
The report, produced by WWF, the Zoological Society of London (ZSL) and the Global Footprint Network, says land species have declined by 25 per cent, marine life by 28 per cent, and freshwater species by 29 per cent.

Brief excerpt: “In summary, the history of biological research is rich in both mechanistic and observational studies of the impacts of extreme weather and climate change on wild species: Research encompasses impacts of single extreme weather events; experimental studies of physiological tolerances; snapshot correlations between climatic variables and species’ distributions; and correlations through time between climatic trends and changes in distributions, phenologies, genetics, and behaviors of wild plants and animals.” Continue reading
