Some Amazon rainforest trees are over 1000 years old finds study
(12/13/2005) Trees in the Amazon rainforest are older than originally believed according to new research published in the Proceedings of the National Academy of Sciences. A team of American and Brazilian researchers using radiocarbon dating methods to study tree growth in the world's largest tropical rainforest found that up to half of all trees greater than 10 centimeters in diameter are more than 300 years old. Some of the trees are 750 to 1,000 years old says Susan Trumbore, a professor of Earth system science at University of California at Irvine and one of the authors of the study.

Amazon deforestation slows in Brazil for 2005
(12/5/2005) Deforestation in the Amazon rainforest fell 37% for the 2004-2004 year according to Brazilian government figures released today. Between July 2004 and August 2005, 7,298 square miles of rainforest (18,900 square kilometers) -- an area almost half the size of Switzerland -- were destroyed.

Energy efficiency helped California grow an extra $31 billion finds study
(12/4/2005) Countering Bush administration claims to the contrary, environmental officials for the state of California and the Brazilian state of Sao Paulo have found significant evidence that greenhouse gas pollution can be substantially reduced at a profit rather than a cost. The study, commissioned by the William and Flora Hewlett Foundation, found that energy efficiency has helped the California economy grow an extra 3 percent - a $31 billion gain - compared to business as usual. Further, the researchers say that each Californian typically saved about $1,000 per year between 1975 and 1995 just through efficiency standards for buildings and appliances.


Exploring freshwater fish habitats in the rainforest of Peru
(11/26/2005) This fall the editor of mongabay.com, a leading environmental science and tropical freshwater fish information site, traveled to the Peruvian Amazon and examined habitats for freshwater fish.

Vampires kill 23 in Brazil, deforestation blamed
(11/7/2005) Rabid vampire bats killed 23 people and attacked more than 1,000 Brazilian officials confirmed last week.

Logging impact worse than thought in the Amazon
(11/1/2005) Research released earlier this month in Science found that Brazil's Amazon rain forest is being degraded twice as fast as deforestation figures suggest. Selective logging, where only one or two valuable tree species are harvested from an area, is driving the forest degradation. The findings have important implications for "sustainable harvesting" schemes that have been promoted as ecologically-sound alternatives to traditional harvesting techniques.

Biopiracy fears hampering research in Brazilian Amazon
(10/30/2005) Somewhere in the Amazon there may be flora and fauna that hold the key to curing diseases ranging from cancer to multiple sclerosis. That, at any rate, is the dream. But the reality is that the search for the next miracle drugs is being hampered by a deep Brazilian suspicion of "biopiracy."


Amazon at record low -- communities isolated, commerce stalled
(10/11/2005) The Amazon River in Peru and parts of Brazil is at its lowest level in 30 years of record keeping. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern. Low water levels are wreaking havoc on the shipping industry in the region. In Iquitos, a city in the heart of the Peruvian Amazon which is only accessible by plane or boat, ships and barges are having difficulty navigating the river, resulting in serious shipping delays. Local officials in Peru are blaming deforestation of the upper reaches of the Amazon in the Andes for the fall in river levels, although it is likely that larger forces are at least equally important. Warmer ocean surface temperatures in the Pacific and low sunspot activity is also affecting weather in the region, while warming in the north Atlantic -- which has helped trigger an unusually strong and destructive hurricane season -- may be preventing the formation of rain clouds over the Amazon Basin.


Extreme drought drops Amazon river to record low levels
(10/7/2005) The Amazon River in Peru and parts of Brazil is at its lowest level in 30 years of record keeping. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern. Low water levels are wreaking havoc on the shipping industry in the region. In Iquitos, a city in the heart of the Peruvian Amazon which is only accessible by plane or boat, ships and barges are having difficulty navigating the river, resulting in serious shipping delays. Local officials in Peru are blaming deforestation of the upper reaches of the Amazon in the Andes for the fall in river levels, although it is likely that larger forces are at least equally important. Warmer ocean surface temperatures in the Pacific and low sunspot activity is also affecting weather in the region. Brazilian meteorologists have discounted the theory that the severe hurricane season off the US Gulf coast has impacted the availability of moisture in the Amazon.

Weight of flooded Amazon river causes Earth to sink 3 inches
(10/5/2005) As the Amazon River floods every year, a sizeable portion of South America sinks several inches because of the extra weight -- and then rises again as the waters recede, a study has found. This annual rise and fall of earth's crust is the largest ever detected, and it may one day help scientists tally the total amount of water on Earth.


Evolutionary history of the origin of potatoes revised -- study
(10/4/2005) Humans have cultivated potatoes for millennia, but there has been great controversy about the ubiquitous vegetable's origins.

Greenheart has developed or is developing canopy walkways in Peru, Nigeria, Madagascar, Ghana, Brazil, Guyana, the United Kingdon, and Canada.


Tropical deforestation affects rainfall in North America
(9/20/2005) NASA research has found that deforestation in the tropics affects rainfall patterns in North America.

Similarly, deforesting lands in Central Africa affects precipitation in the upper and lower U.S Midwest, while deforestation in Southeast Asia was found to alter rainfall in China and the Balkan Peninsula.


NASA Satellite Data Used to Assess Amazon Deforestation
(9/15/2005) The Amazon, a vast tropical forest stretching across South America, is so large that is virtually impossible to study the evolving landscapes within the basin without the use of satellites. Scientists have used satellite imagery of the Amazon for more than 30 years to seek answers about this diverse ecosystem and the patterns and processes of land cover change. This technology continues to advance and a new study shows that NASA satellite images can allow scientists to more quickly and accurately assess deforestation in the Amazon.

Amazon deforestation lower than last year says Brazil
(8/27/2005) Yesterday Brazil announced that 3,515 square miles (9,103 square kilometers) of Amazon rainforest were destroyed between August 2004 and July 2005, a marked decline from the 7,229 sq. mi. (18,723 sq. km.) in the same period a year earlier. While the government has tried to take credit for the drop, analysts say the slowing is more likely the result of lower commodity prices, giving farmers less incentive to clear forest land.

Brazil's grasslands could replace food production of American heartland
(8/1/2005) Today when people mention Brazil and agriculture, people often first envision the Amazon rainforest giving way to soybean plantations and cattle farms.

Most affected will be growers in the tropical northeastern part of the island who have relied on the valuable crop for years.
