Five forest figures for the International Day of Forests. This is part of a series of blogs focussed on the Sustainable Development Goals and data from the 2016 Edition of World Development Indicators.

WLD 10 Nature is good medicine. Carbon-storing Amazon forest is losing its touch. The Amazon has long been seen as a life preserver of sorts in the global warming fight, its lush forest storing billions of tons of carbon.
But now a paper published in Nature Wednesday says that the Amazon is losing its capacity to serve as a carbon sink. In a 30-year study of the South American tropical forest, an international team found that the Amazon has gone from storing 2 billion tons of carbon dioxide each year in the 1990s to half that now. As a result, emissions across Latin America have now overtaken the amount of carbon dioxide stored. "The Amazon has been doing us a great service in taking up large part of our CO2 emissions," Roel Brienen, the lead author, from the University of Leeds, told CBS News. "What our study basically shows at least for the Amazon basin is that there is a limit to how far this goes, how far the Amazon can continue to take up carbon from the atmosphere and store it in the forests. " William R. Billion Tree Campaign - Billion Tree Campaign. "Tree census" estimates total number of trees on Earth. More than 3 trillion trees now grow on Earth, seven times more than scientists previously thought.
But it's also trillions fewer than there used to be, a new study concludes. A United Nations-affiliated youth group had a goal of planting one billion trees and Yale forestry researcher Thomas Crowther was asked if planting that many trees would do anything to help combat human-made climate change. Trees capture and store heat-trapping carbon dioxide. Crowther said first he had to figure out how many trees are on Earth and that number was far more than anyone expected: 3.04 trillion trees, according to a study published Wednesday in the journal Nature.

Nature Is Speaking – Harrison Ford is The Ocean. Launch of publication to value nature - The Nature Conservancy Australia. New Report Calls for Policy Reforms to Achieve Planetary and Human Health. NAIROBI, October 30, 2015 - Changing environmental conditions such as increased carbon dioxide emissions, rampant use of fertilizer and the acidification of the oceans could lead to major health challenges for millions of people, according to a new report launched today in Nairobi.
The Rockefeller Foundation-Lancet Commission on Planetary Health report, Safeguarding Human Health in the Anthropocene Epoch, establishes clear linkages between planetary and human health. The report explains that the health and well-being of future generations is being jeopardized by the unprecedented degradation of natural resources and ecological systems. An increasing population, unsustainable consumption and production and the over-exploitation of natural resources are straining the planet's resources and having an impact on human health. Peak Oil: Myth Or Coming Reality? In 1956, a geoscientist named M.
King Hubbert formulated a theory which suggested that U.S. oil production would eventually reach a point at which the rate of oil production would stop growing. After production hit that peak, it would enter terminal decline. Light pollution atlas shows areas of Earth that cannot see the stars – video. Reykjavik goes dark for Northern Lights show. The lights went out in Reykjavik on Wednesday night to give people a chance to enjoy one of the night sky's most impressive spectacles - the Aurora Borealis.
Reykjavik council announced that street lighting would be switched off for an hour in the city centre and several other districts from 22:00 local time, in order to cut out the light pollution that can hamper sky-watching. Theconversation. While we can never know for sure, an extraordinary number of animals and plants are threatened with extinction — up to a third of all mammals and over a tenth of all birds.
And the problem is getting worse. At the same time, we have more land and sea than ever in protected areas (“parks”) — more than 200,000 protected areas covering about 15% of the world’s land area and 3% of the oceans. So why are protected areas making so little difference? Research Shows Plants Are Sentient. Will We Act Accordingly? Research continues to verify the intelligence of plants.
If we begin to regard them as sentient beings, will our treatment of them improve? ©John T. Making Sense of Water. BERKELEY, Calif. — Almost every number used to analyze California’s drought can be debated, but this can be safely said: No level of restrictions on residential use can solve the problem. The solution lies with agriculture, which consumes more than its fair share. That doesn’t mean homeowners can’t and shouldn’t cut back. But according to estimates by the Public Policy Institute of California, more water was used to grow almonds in 2013 than was used by all homes and businesses in San Francisco and Los Angeles put together. Even worse, most of those almonds are then exported — which means, effectively, that we are exporting water.
If you don't already think of water as power, these folks make it crystal clear. Theconversation. Nearly half of 200 Australian species are threatened by climate change, according to our research published today in PLOS ONE. Climate change is one of the major contributors to global biodiversity loss, and plant and animal species can be affected by climate change in different ways. Some may be directly affected by sea level rise or snow melt, whereas some may lose a pollinator or prey species that they rely on.
Species that cannot move to more suitable habitats, or who have no suitable habitat left, risk becoming extinct. 10 Australian species at extreme risk of extinction: can they be saved? 'Giraffes are dangerous': another trophy hunter under fire after defending hobby. A big-game trophy collector from Idaho has been criticised by animal rights activists over online images of herself posed with the carcasses of a giraffe and other wildlife she killed during a recent guided hunt in South Africa. Sabrina Corgatelli, an accountant for Idaho State University, appeared on NBC’s Today show on Monday to defend trophy hunting amid mounting international outrage over the killing in July of Cecil, Zimbabwe’s most famous lion, by an American dentist.
“Everybody thinks we’re cold-hearted killers and it’s not that,” Corgatelli said in the nationally televised interview. “There is a connection to the animal and just because we hunt them doesn’t mean we don’t have a respect for them. “Giraffes are very dangerous animals. Plant Behavior. The Society for Plant Neurobiology was formed after the First International Symposium on Plant Neurobiology was held in Florence in 2005.
This, and each of the subsequent symposia, were scientifically energizing and exciting, drawing a diverse array of participants. Plant Neurobiology describes a newly named, but also old and fascinating field in plant biology addressing the physiological basis of adaptive behavior in plants. Perhaps this field could be called "Sensory Biology in Plants" or something similar. However, these names don't quite cover topics like plant cytology and anatomy, adaptive plant behavior, signaling and communication in symbiosis and pathogenesis, or newly emerging topics like for instance plant immunity, plant memory and learning, plant-plant communication, as well as plant intelligence.
