When scanning for emissions from a mud volcano in western Turkmenistan in January 2019, a satellite called Claire came across a large plume of methane drifting across the landscape. … The company operating the satellite, GHGSAT passed details via diplomats to officials in Turkmenistan, and after a few months the leaks stopped. This largely unknown incident illustrates two things: that satellites can play an important role in spotting leaks of greenhouse gases and, rather worryingly, that the extent of such leaks is often greatly underestimated. The data from Claire suggested the leak in Turkmenistan had been a big one…142,000 tonnes of methane. This made the Turkmenistani leak far bigger than the 97,000 tonnes of methane discharged over four months by a notorious blowout at a natural-gas storage facility in Aliso Canyon, California, in 2015, which is reckoned to have been the worst natural-gas leak yet recorded in America. There have been other big leaks, too…
The reason for concern is that although methane, the main constituent of natural gas, does not linger in the atmosphere for anywhere near as long as carbon dioxide does, it is a far more potent heat-trapping agent. About a quarter of man-made global warming is thought to be caused by methane. And between a fifth and a third of the methane involved is contributed by the oil and gas industry. Methane can be detected spectroscopically. Like other gases, it absorbs light at characteristic frequencies. With a spectrometer mounted on a satellite it is possible to analyse light reflected from Earth for signs of the gas. As with the satellites that carry them, spectrometers come in many shapes and sizes. Tropomi can also detect the spectral signs of other polluting gases, such as nitrogen dioxide, sulphur dioxide and carbon monoxide.
Other methane-hunting satellites are coming. These include one due for launch in 2022 by Methanesat, an affiliate of the Environmental Defence Fund, an American non-profit organisation. The 350kg satellite will cost $88m to build and put into orbit. It will scan an area of land 200km wide with a resolution of 1km by 1km. According to Methanesat, it will be the most sensitive to emission levels yet, being able to detect methane concentrations as low as two parts-per-billion. Data collected by the satellite will be publicly available.

Radioactive cesium from the crippled Fukushima No. 1 nuclear power plant continued to flow into Tokyo Bay for five years after the disaster unfolded in March 2011, according to a researcher. Hideo Yamazaki, a former professor of environmental analysis at Kindai University, led the study on hazardous materials that spewed from the nuclear plant after it was hit by the Great East Japan Earthquake and tsunami on March 11, 2011.
Mr Xi has been showing a growing interest in Arctic countries. In 2014 he revealed in a speech that China itself wanted to become a “polar great power”..,,In January 2018 the Chinese government published its
When sub-Saharan Africa comes up in discussions of climate change, it is almost invariably in the context of adapting to the consequences, such as worsening droughts. That makes sense. The region is responsible for just 7.1% of the world’s greenhouse-gas emissions, despite being home to 14% of its people. Most African countries do not emit much carbon dioxide. Yet there are some notable exceptions.
Mukono- Residents of Kitoba village in Mukono District have opposed plans by the Uganda Atomic Energy Council (AEC) to construct a nuclear and atomic waste site in the area. The residents fear the dump for non-functional atomic equipment, including X-rays and cancer machines, will compromise their safety. Already, the residents at Canaan Sites are suspicious of a container that has been standing on the 11.5 acres of land acquired by the AEC in 2011.
Nigeria has long ignited interest from oil firms, but it can be a dangerously combustible environment when it comes to the risk of corruption. Two firms caught up in scandals are Royal Dutch Shell and Eni, Italy’s state-backed energy group.
China on January 25, 2018 outlined its ambitions to extend President Xi Jinping’s signature Belt and Road Initiative to the Arctic by developing shipping lanes opened up by global warming. Releasing its first official Arctic policy white paper, China said it would encourage enterprises to build infrastructure and conduct commercial trial voyages, paving the way for Arctic shipping routes that would form a “Polar Silk Road”…China, despite being a non-Arctic state, is increasingly active in the polar region and became an observer member of the Arctic Council in 2013.
South Carolina is suing the U.S. government to recover $100 million in fines it says the Department of Energy owes the state for failing to remove one metric ton of plutonium stored there. The lawsuit was filed on August 7, 2017.
One day in March 2017, he Rioja Knutsen tanker, filled with liquefied natural gas, was traveling from the U.S. to Portugal. Suddenly, Mexico’s power company lobbed in a higher bid for its cargo. At the Bahamas, the ship abruptly made a starboard turn and headed south. How natural gas is bought and sold in the world’s scattered regional markets for the fuel is changing rapidly. Ships such as the Rioja Knutsen are stitching those regions together and a single global market is emerging. This is already how nearly every other hydrocarbon, from crude oil to obscure petrochemicals, is sold. As gas joins the club, the effects will ripple through energy prices, company profits, the environment and geopolitics.
Russia’s sale of one-fifth of its state-owned oil company to Qatar and commodities giant Glencore PLC last year had an unusual provision: Moscow and Doha agreed Russia would buy a stake back, people familiar with the matter said. Russian President Vladimir Putin hailed the $11.5 billion sale of the Rosneft stake in December 2016 as a sign of investor confidence in his country. But the people with knowledge of the deal say it functioned as an emergency loan to help Moscow through a budget squeeze.
