"After a year of consultations and over 4 million public comments, President Obama's Clean Power Plan will be finalised early next week.
The strategy will outline restrictions on CO2 from electricity that individual states will have to implement.
To give reluctant states more time to comply, the starting date is expected to be delayed by 2 years.
It's likely that new supports for renewable energy will also be announced.
In June last year the US Environment Protection Agency (EPA) first put forward its proposals for restrictions on power plants.
The EPA said that emissions from electricity generation need to be reduced by 30% of the 2005 level by 2030.
At that time the EPA said that individual states need to get their plans in place by 2016 and they were to become operational by 2020.
But after consultations with industry, states and 4.3 million comments from the public, the EPA is likely to extend the deadline for the start of carbon cutting until 2022.
But while some have seen the delay as a weakening of Obama's climate commitment, the White House Chief of Staff hinted that the new rules would actually make a bigger overall impact on emissions.
"There really is no overstating how big this year is for climate change," said Denis McDonough, speaking at a Washington forum earlier this week.
"We will finalise a stronger rule."
The thinking appears to be that a shorter deadline makes it more likely that states will switch from coal to natural gas, as they have been doing in recent years".

"A team of marine researchers has discovered a three-way conflict raging at the microscopic level in the frigid waters off Antarctica over natural resources such as vitamins and iron. The competition has important implications for understanding the fundamental workings of globally significant food webs of the Southern Ocean, home to such iconic Antarctic creatures as penguins, seals, and orcas".

"North of the Aleutian Islands, submarine canyons in the cold waters of the eastern Bering Sea contain a highly productive 'green belt' that is home to deep-water corals as well as a plethora of fish and marine mammals".

"A new study has concluded California accumulated a debt of about 20 inches of precipitation between 2012 and 2015 -- the average amount expected to fall in the state in a single year. The deficit was driven primarily by a lack of air currents moving inland from the Pacific Ocean that are rich in water vapor".

"For centuries, people have transformed and splintered landscapes and ecosystems in North America. This radical altering of nature makes it tough for scientists to analyze the continent’s life-sustaining carbon cycle — the biological, geological and chemical routes the element carbon takes to shift among earth, water and atmosphere".

"The combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps), researchers have discovered".

"Despite their remarkably similar appearance, the 'golden jackals' of East Africa and Eurasia are actually two entirely different species. The discovery, based on DNA evidence, increases the overall biodiversity of the Canidae -- the group including dogs, wolves, foxes, and jackals -- from 35 living species to 36".

"In a global study of drought impacts, forest trees took an average of two to four years to resume normal growth rates, a revelation indicating that Earth's forests are capable of storing less carbon than climate models have assumed".

"The findings come from reconstructions of ancient ocean circulation patterns reported today in the journal Nature.
"The Antarctic Circumpolar Current (ACC) is today the strongest ocean current in the world and it helps keep Antarctica cold," says marine geophysicist co-author, Dr Joanne Whittaker of the University of Tasmania.
"It thermally isolates Antarctica so you can't get warmer currents coming down from lower latitudes and warming up the continent."
The current flows clockwise around Antarctica from west to east.
"There's no land in the way, so the strong westerly winds can blow unobstructed and the massive current goes around and around in a loop," says Whittaker.
As well as helping to stop Antarctica's ice sheets from melting, the current helps regulate the exchange of heat and carbon between the ocean and the atmosphere".

The strongest ocean current in the world only started flowing once Tasmania drifted north of the prevailing westerly winds 30 million years ago, say researchers.

"Using a climate model that can tag sources of soot and track where it lands, researchers have determined which areas around the Tibetan Plateau contribute the most soot -- and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes. The study might help policy makers target pollution reduction efforts".

"A new study addresses an important question in climate science: how accurate are climate model projections? Climate models are used to estimate future global warming, and their accuracy can be checked against the actual global warming observed so far. Most comparisons suggest that the world is warming a little more slowly than the model projections indicate. Scientists have wondered whether this difference is meaningful, or just a chance fluctuation".

Scientists and engineers helping save the planet.
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!
