Tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out
MoS2 Nanopores, developed by the University of Illinois, seems to be an energy-efficient technique for removing salt from seawater. The material, a nanometer-thick sheet of molybdenum disulfide (MoS2) riddled with tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out, a process called desalination.

According to climate researchers, more rain than snow will fall in the Arctic. Moreover, oceans are getting hotter, and they’re also losing oxygen
According to climate researchers in the Netherlands, at the end of this century more rain than snow will fall in the Arctic. It was already known that, due to global warming, up to 60% more precipitation would fall in the Arctic.
The researchers now argue that it mainly involves rain, while scientists always presuppose the precipitation would be snow. Read More
In 1989, the organization changed the design of a drilling platform in order to take account of extreme weather and rising sea levels.
Shell produced a report on global warming called ‘Climate of Concern’ in 1986. In 1991 they made the video documentary for the public. It warned that trends in global temperatures raised serious risks of famines, floods and climate refugees.
But in the quarter century since, Shell has continued to invest heavily in fossil fuels.
Already in the eighties, Shell understood that climate change would affect its own operations. In 1989, the organization changed the design of a drilling platform in order to take account of extreme weather and rising sea levels.
Between the years 1986 and 2006, Toronto experienced not one but eight storms of the magnitude that had been predicted to occur no more than once in a quarter-century. The Finch Avenue Washout was the capper, a one-in-100-years storm for which the city’s infrastructure was woefully under-designed.
The Netherlands is to host a new Global Centre of Excellence on Climate Adaption (GCEA), set up by the Dutch and Japanese governments in collaboration with the UN environment programme (UNEP).
The centre will advise countries, businesses and organizations on how to adapt their practices to comply with the Paris climate change agreement, which comprises measures designed to keep the global temperature increase below 2 degrees.
Working of the capacity down pipe (1, empty; 2, filling-up; 3, over-flowing; 4; full; 5, drained)
A case study in Manchester with different solutions for water infiltration and retention systems, showed that soak-aways and infiltration trenches are generally less preferred than capacity down pipes, ponds and filter strips.
And this wateringpipe – the capacity downpipe (CDP) – works even better.
Flared gas is a bigger problem than thought. Contrary to what has been agreed with the oil industry, worldwide the industry flared not less, but more gas.
In 2015, about 147 billion cubic meters which is a CO2 footprint of around 350 million tonnes!
The world bank published the figures in a report. Globally, over 16,000 oil wells are flaring gas.
The amount of wasted gas corresponds to the gas consumption of the UK, Germany and Switzerland together. If the gas was burned in a power plant, it could supply the whole of Africa with electricity. Read More
The next few decades will be the most rapid period of urban growth in human history, with 2.6 billion additional urban dwellers expected by 2050 (UNPD, 2011). All pleople will need water, but surprisingly little is known globally about where large cities obtain their water or the implication of this infrastructure for the global hydrologic cycle.
More than 2.5 billion people don’t have access to basic levels of fresh water for at least one month each year – a situation growing ever more critical as urban populations expand rapidly
Traditionally, cities, facing increased demand for water, along with variable supply, have relied on large-scale, supply-side infrastructural projects such as dams and reservoirs.
This is termed ‘supply-side’ management. According to Robert Brears in his blog, this supply-side management is out dated.
Its costly in economic, environmental and political terms. Read More
The third place, which isn’t bad at all, is for Stockholm.
The new ARCADIS Sustainable Cities Index explores the three demands of social (People), environmental (Planet) and economic (Profit) to develop an indicative ranking of 100 of the world’s major cities. Read More
Even if global warming is capped at 2C, 20% of the world’s population will have to migrate away from coasts swamped by rising oceans.
Even if global warming is capped at governments’ target of 2C, 20% of the world’s population will be to migrate to higher area’s because of rising sea levels.
Countries like the Netherlands and Bangladesh and cities including New York, London, Rio de Janeiro, Cairo, Calcutta, Jakarta and Shanghai would all be submerged because of melting polar ice caps and sea-level rise. Read More
Using robots to lay down concrete made from moon soil around the entirety of the moon’s equator — 400 km wide by 11,000 km long — the power generated through the solar array would then be transferred along power cables to microwave power transmission antennas which would then beam the electricity to receiving stations located around the Pacific Rim.
LSP – Lunar Solar Power – can provide an unlimited power supply sent back to the earth in microwaves.
Why are international politicians the big holdout on this unlimited green power resource?
Could it be because the oil industry keeps paying off all the politicians? Read More
SF doesn’t know which neighborhoods will be worst hit after a given storm, but they do know sea levels are rising, and that with climate change, those hurricanes off Mexico’s Pacific Coast could come north some day. They don’t know when or how severe, but we could get a 25 foot storm surge at some point.
In San Francisco (SF), where the waterfront has been a political battleground for decades, sea-level rise is too easy to ignore.
While SF is less vulnerable to rising sea levels than other parts of the Bay Area, portions of areas bordering the bay would be at risk.
The challenge is to accommodate the bay’s impending expansion as it rises because of our warming planet. And to accomplish that in a way that won’t put our human and environmental resources at risk. Read More
The Hellisheidi power plant is the world’s largest geothermal facility. It provides the energy for Iceland’s capital, Reykjavik, plus power for industry, by pumping up volcanically heated water to run turbines
Iceland has done it again. No, its not football. It’s even better. They successfully turned CO2 into stone!
In Iceland, scientists and engineers are fighting climate change by injecting CO2 deep into volcanic rocks. Read More
