A new radar and satellite system will give brands greater forest commodity sourcing transparency Companies that source commodities from areas potentially at risk of deforestation will have a new weapon in their armoury from the start of 2017. Starling is a high-resolution satellite auditing service that can be used to check forest management practices, in particular in source countries for palm oil, such as Indonesia and Malaysia.

Japanese scientists are preparing to launch a satellite that will use a 300-meter electromagnetic tether to snag orbiting trash left over from past satellites and space missions. The magnetic field will slow the trash, causing it to gradually fall closer to Earth and eventually burn up in the atmosphere. It's thought there are tens of millions of trash fragments in orbit around the Earth.

The satellites measure changes in Earth's gravitation field that signal shifts in the movement of water across and under Earth's surface.

Sea level rise is caused primarily by two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms. The first chart tracks the change in sea level since 1993 as observed by satellites. The second chart, derived from coastal tide gauge data, shows how much sea level changed from about 1870 to 2000.

A major initiative has been launched this week under the banner Global Forest Watch, promising to use advanced satellite and analytics technology to lead a new crackdown on illegal deforestation.

ESA's Clean Space initiative is looking at developing a satellite that can rendezvous with space debris and render it harmless by netting it like fish. According to ESA, there are 17,000 trackable objects larger than a coffee cup orbiting the Earth and many more down to the size of paint chips. This may not seem like anything very dangerous, but at orbital velocity, even a paint chip can hit like a bullet and a steel nut has the impact of a hand grenade.

America's cities are succeeding in curbing air pollution, according to data from NASA's Aura satellite. New York City has seen a 32% decrease in nitrogen dioxide since 2005, Atlanta's levels fell by 42%, and Denver scored a 22% decrease.

The map shows the world's carbon emissions from 1997 to 2010, say the scientists who made it. The data came from satellite measurements and reported emissions rates from factories and power plants, among other sources.

From deforestation to irrigation to species loss, the expanding human population has been dramatically re-shaping the face of the Earth. These interactive maps bring together a wealth of satellite imagery and other data sets to create an atlas of humanity's influence on the planet.

According to the Brazilian NGO's analysis of satellite data, 1,373 square kilometers of rainforest was chopped down between August 2014 and December 2014, a 224 percent increase relative to the prior corresponding period a year before. Forest degradation from selective logging and fires is pacing 664 percent ahead of last year. Forest degradation typically precedes outright clearing.

A palm oil supplier to Mars, Nestlé, PepsiCo and Unilever is destroying rainforests in Papua, Indonesia, a new investigation by Greenpeace International has revealed. Satellite analysis suggests that around 4,000 hectare of rainforest were cleared in PT Megakarya Jaya Raya concession between May 2015 and April 2017-an area almost half the size of Paris.

Satellite readings show that atmospheric methane and carbon dioxide are continuing to increase despite global efforts to reduce emissions. Methane concentrations were somewhat constant until 2007, but since then have increased at about 0.3% per year, whereas global carbon dioxide levels continue to rise at about 0.5% per year. The world's atmospheric methane and carbon dioxide levels continue to climb despite endeavors to rein in global emissions, new research shows. Carbon levels have risen by 0.5% per year since 2007, and methane levels are rising at about 0.3% per year.

More than half of Earth's 37 largest aquifers are being depleted, according to gravitational data from the GRACE satellite system.

More than half of the world's 37 biggest aquifers are running dry, putting at risk the freshwater supplies of hundreds of millions of people, according to a NASA analysis. "The water table is dropping all over the world," said NASA water scientist Jay Famiglietti.
