Ancient Trees. Pour sa série Ancient Trees, la photographe américaine Beth Moon parcourt le monde depuis 14 ans à la recherche des plus vieux et des plus majestueux arbres du monde, du séquoia géant General Sherman aux baobabs de Madagascar.
Ses photographies sont ensuite développées avec un procédé de tirage Platine / Palladium, l’un des seuls capables de résister durablement au temps et de rivaliser avec l’âge de ces arbres. Les images de Beth Moon sont également éditées en livre chez Abbeville Press. Images © Beth Moon / Abbeville Press / via. Trump Assault on Climate. Donald Trump will launch a major assault on Barack Obama’s climate change legacy on Tuesday with a series of orders that undermine America’s commitment to the Paris agreement.
Asked by the Guardian if Trump accepted the science of manmade climate change, a senior White House official replied: “Sure, yes, I guess, I think the president understands the disagreement over the policy response and you’ll see that in the order … We’re taking a different path.” Trump will sign executive orders and presidential memoranda that suspend, rescind or review several measures that were central to Obama’s effort to combat global warming. They include a review of the clean power plan, which restricts greenhouse gas emissions at coal-fired power plants. Trump, who has called global warming a “hoax”, has criticised the power-plant rule and others as placing an unnecessary burden on American workers and the struggling US coal industry. Trump Purge of Data. As an Arctic researcher, I’m used to gaps in data.
Just over 1% of US Arctic waters have been surveyed to modern standards. Venus Game. It is a vision of a future so apocalyptic that it is hard to even imagine.
But, if leading scientists writing in one of the most respected academic journals are right, planet Earth could be on course for global warming of more than seven degrees Celsius within a lifetime. Antarctic Shelf Breakoff. A giant iceberg, with an area equivalent to Trinidad and Tobago, is poised to break off from the Antarctic shelf.
Next Mass Extinction. The number of wild animals living on Earth is set to fall by two-thirds by 2020, according to a new report, part of a mass extinction that is destroying the natural world upon which humanity depends.
The analysis, the most comprehensive to date, indicates that animal populations plummeted by 58% between 1970 and 2012, with losses on track to reach 67% by 2020. Researchers from WWF and the Zoological Society of London compiled the report from scientific data and found that the destruction of wild habitats, hunting and pollution were to blame. Planet Vital Signs.
Do the Math. US Trees Dying. JB Friday hacked at a rain-sodden tree with a small axe, splitting open a part of the trunk.
Lol, yaura plus d'hiver sans arbres – teoprime
The wood was riven with dark stripes, signs of a mysterious disease that has ravaged the US’s only rainforests – and just one of the plagues that are devastating American forests across the west.
Friday, a forest ecologist at the University of Hawaii, started getting calls from concerned landowners in Puna, which is on the eastern tip of Hawaii’s big island, in 2010. Their seemingly ubiquitous ohi’a trees were dying at an astonishing rate. The leaves would turn yellow, then brown, over just a few weeks – a startling change for an evergreen tree. Months of Record-breaking. As the string of record-breaking global temperatures continues unabated, June 2016 marks the 14th consecutive month of record-breaking heat.
According to two US agencies – Nasa and Noaa – June 2016 was 0.9C hotter than the average for the 20th century, and the hottest June in the record which goes back to 1880. It broke the previous record, set in 2015, by 0.02C. The 14-month streak of record-breaking temperatures was the longest in the 137-year record. Global Warming Spiral. The temperature spiral that took the world by storm has an update.
If you think the heat is on in our current climate, you ain’t seen nothing yet. To recap, University of Reading climate scientist Ed Hawkins wrecked the internet a few weeks ago with a revolutionary new way to look at global temperatures. Using a circular graph of every year’s monthly temperatures and animating it, Hawkins’ image showed planetary heat spiraling closer to the 2 degrees C threshold in a way no bar or line graph could do. His tweet with the original graphic has been shared 15,000 times, and it’s been dubbed the most compelling climate visualization ever made (sorry, landmarked Keeling Curve).
The spiral’s popularity can be attributed in part to its hypnotic nature and the visceral way it shows the present predicament of climate change. Climate Blackmail. The EU abandoned or weakened key proposals for new environmental protections after receiving a letter from a top BP executive which warned of an exodus of the oil industry from Europe if the proposals went ahead.
In the 10-page letter, the company predicted in 2013 that a mass industry flight would result if laws to regulate tar sands, cut power plant pollution and accelerate the uptake of renewable energy were passed, because of the extra costs and red tape they allegedly entailed. The measures “threaten to drive energy-intensive industries, such as refining and petrochemicals, to relocate outside the EU with a correspondingly detrimental impact on security of supply, jobs [and] growth,” said the letter, which was obtained by the Guardian under access to documents laws. Carbon Release Rate Record. Humanity is pumping climate-warming carbon dioxide into the atmosphere 10 times faster than at any point in the past 66m years, according to new research.
The revelation shows the world has entered “uncharted territory” and that the consequences for life on land and in the oceans may be more severe than at any time since the extinction of the dinosaurs. It comes as the World Meteorological Organisation released its Status of the Climate Report detailing a string of weather and climate records that were broken in 2015. “The future is happening now,” said WMO secretary-general Petteri Taalas in a statement released alongside the report.
“The alarming rate of change we are now witnessing in our climate as a result of greenhouse gas emission is unprecedented in modern records.” A Really Inconvenient Truth. Climate Point of no Return. Historians may look to 2015 as the year when shit really started hitting the fan.

Some snapshots: In just the past few months, record-setting heat waves in Pakistan and India each killed more than 1,000 people. In Washington state's Olympic National Park, the rainforest caught fire for the first time in living memory. Sea Level Bombshell. Photo by Joe Raedle/Getty Images In what may prove to be a turning point for political action on climate change, a breathtaking new study casts extreme doubt about the near-term stability of global sea levels.
The study—written by James Hansen, NASA’s former lead climate scientist, and 16 co-authors, many of whom are considered among the top in their fields—concludes that glaciers in Greenland and Antarctica will melt 10 times faster than previous consensus estimates, resulting in sea level rise of at least 10 feet in as little as 50 years.
