Delayed action on climate to result in irreversible change and high costs

Delayed action on climate to result in irreversible change and high costs
Show

The physics of Earth’s natural systems show that a delay—of even a decade—in reducing CO2 emissions will lock in large-scale, irreversible changes. If carbon dioxide emissions do not begin to trend down this decade, it will be nearly impossible to stabilize the climate at any acceptable level.

WASHINGTON (Reuters) – The United States is on a pace in 2011 to set a record for the cost of weather-related disasters and the trend is expected to worsen as climate change continues, officials and scientists said on Thursday.

"The economic impact of severe weather events is only projected to grow," Senator Dick Durbin said at a hearing of the Senate Subcommittee on Financial Services and Government, which he chairs. "We are not prepared. Our weather events are getting worse, catastrophic in fact."

NEW YORK--(EON: Enhanced Online News)--New research from Bloomberg New Energy Finance reveals that despite many platitudes and pledges, governments of the world are spending substantially more on subsidizing dirty forms of energy than on renewables and biofuels. In fact, support for cleaner sources is dwarfed by the help the oil, coal, and other fossil fuel sectors receive.

(Reuters) - Nearly 3 billion people, or two-fifths of the world's population, were at risk of contracting malaria in 2009 and closer study of the mosquito's life cycle is needed to combat the disease, researchers said in two reports.

In the first study, scientists mapped out the geographical spread of the Plasmodium vivax -- the most common parasite that causes malaria -- using reported cases of malaria and details on temperature and aridity.

The worst drought in 60 years has hit the Horn of Africa region, an area in east Africa that includes Somalia, Ethiopia and Kenya.

A recent satellite-derived animation from the European Space Agency illustrates the crisis as it worsened over the summer. The images above show soil moisture in the region from April to mid-July of this year. Green and blue depict higher levels of soil moisture while the increasing spread of orange and yellow illustrates areas with little to no moisture.

Small fish said vital to seas; lower catches urged

OSLO, July 21 (Reuters) - Small fish play a big role in the oceans and catches should be cut sharply to safeguard marine food chains from plankton to blue whales, an international team of experts said on Thursday.

Rising human exploitation of little fish -- including anchovy, sardine, herring, mackerel and capelin -- had had far less attention in marine research compared to big commercial species such as cod, tuna, swordfish or salmon, they said.
