"A world-leading climate change target up to the early 2030s is set to be confirmed by the British government.
Ministers are expected to announce that the UK will cut carbon emissions by 57% by 2032, from 1990 levels.
The announcement will help reassure the investors needed to overhaul the UK's ageing energy system.
The energy industry will be relieved after cuts in renewables subsidies and the vote to leave the EU, which influences so much of the UK's energy.
Energy Secretary Amber Rudd said climate change remained one of the most serious long-term risks to the economy".

"Pledges made for the Paris agreement on climate change last winter would lead to global temperature rise of 2.6 to 3.1°C by the end of the century, according to a new analysis published in the journal Nature. In fact, the entire carbon budget for limiting warming to below 2°C might have been emitted by 2030, according to the study.
"The Paris Agreement was a historical achievement for the world's response to climate change, aiming at limiting warming to below 1.5°C and 2°C. It puts in place a flexible framework for a long-term transformation towards a low-carbon society. But our analysis shows that these measures need to be strengthened in order to have a good chance of keeping warming to well below 2°C, let alone 1.5°C," says Joeri Rogelj, a researcher at the International Institute for Applied Systems Analysis (IIASA) who led the study.
The 2°C target aimed to limit future climate change to an average temperature increase of below 2°C above preindustrial levels, as research suggested that this could help avoid some of the most dangerous impacts of climate change. The target was agreed upon by 190 countries at the Cancun climate meeting in 2010. In Paris last December, countries strengthened this target by requiring temperatures to be limited to "well below" 2°C and furthermore agreed that they should strive to limit temperature rise even further, to 1.5°C. Some studies suggest that even two degrees of warming would lead to unacceptable impacts, particularly in vulnerable countries such as island nations and least-developed countries".

"For the first time, scientists have been successful in measuring the processes by which an entire forest "breathes," using sophisticated technology involving flux towers and new instrumentation that can precisely measure two different types (isotopes) of carbon dioxide in the air. A team led by Richard Wehr and Scott Saleska at the University of Arizona obtained detailed long-term measurements of the respiration and photosynthesis rates of a temperate deciduous forest during the day and the night".

"Northern wrens are larger and more resilient to winter weather than those living in the south, new research reveals. The research means that populations inhabiting regions where winters are more severe show some form of adaptation. The research team say that their findings have particular relevance to our understanding of how birds and other species are able to respond to climate change".

"Crucial peatlands carbon-sink vulnerable to rising sea levels, research shows
Rising sea-levels linked to global warming could pose a significant threat to the effectiveness of the world's peatland areas as carbon sinks, a new study has shown.
The pioneering new study, carried out by Geographers at the University of Exeter, examined the impact that salt found in sea water has on how successfully peatland ecosystems accumulate carbon from the atmosphere.
The researchers studied an area of blanket bog - a peat bog that forms in cool regions susceptible to high rainfall - at Kentra Moss, in Northwest Scotland.
They discovered that the rate at which the peatland area accumulated carbon was significantly impacted as the concentration of salt rose.
The results indicate that rising sea levels, linked to predicted climate change, could pose a serious threat to the future security of the peatlands because they would inundate areas and deposit more salt, further inland".

"Antarctic sea ice production spanning more than 20 years has been understood through the analysis of satellite observations using specially developed techniques. The results of this analysis revealed that changes to the sea ice production in the Southern Ocean were caused mainly because of surrounding ice shelf and fast ice conditions, rather than by wind, temperature, or other factors".

"A new map created with measurements from an airborne instrument developed by NASA’s Jet Propulsion Laboratory, Pasadena, California, reveals the devastating effect of California’s ongoing drought on Sierra Nevada conifer forests.
The map will be used to help the U.S. Forest Service assess and respond to the impacts of increased tree mortality caused by the drought, particularly where wildlands meet urban areas within the Sierra National Forest".

"Climate has influenced the distribution patterns of Adélie penguins across Antarctica for millions of years.
The geologic record shows that as glaciers expanded and covered Adélie breeding habitats with ice, penguin colonies were abandoned. When the glaciers melted during warming periods, this warming positively affected the Adélie penguins, allowing them to return to their rocky breeding grounds.
But now, University of Delaware scientists and colleagues report that this beneficial warming may have reached its tipping point.
In a paper published today (June 29) in Scientific Reports, the researchers project that approximately 30 percent of current Adélie colonies may be in decline by 2060 and approximately 60 percent may be in decline by 2099.
"It is only in recent decades that we know Adélie penguins population declines are associated with warming, which suggests that many regions of Antarctica have warmed too much and that further warming is no longer positive for the species," said the paper's lead author Megan Cimino, who earned her doctoral degree at UD in May".

Introduction
The Azimuth Project is an international collaboration to create a focal point for scientists and engineers interested in saving the planet. Our goal is to make clearly presented, accurate information on the relevant issues easy to find, and to help people work together on our common problems.  We need your help! 

The Azimuth Project includes a wiki, a blog, and a discussion forum

This Azimuth page here on Google+ lets you keep track of news related to energy, the environment and sustainability.  Posts on this page are written by Rasha Kamel, John Baez, Jim Stuttard, Frederik De Roo and David Tanzer.  The posts reflect the individual authors views and taste; we don't agree about everything!
