EPIC New Science from 1 Million Miles Away I NASA

Published on Nov 8, 2018
NASA's Earth Polychromatic Imaging Camera (EPIC) sits onboard NOAA's Deep Space Climate Observatory (DSCOVR) satellite at the Lagrange point 1, a million miles away from Earth.

EPIC has been imaging the sunlit side of Earth between 13 and 22 times a day since 2015. Now, scientists have developed ways to use these images to study specific elements of our home planet's atmosphere and plant life, like ozone in the stratosphere, the makeup of clouds and the health of vegetation on land.

Growing Crops in the Desert with Seawater | Freethink

Published on Nov 13, 2018
Water is in short supply in much of the world - but what if we use seawater? It’s been a dream for many years, but now technology is making it possible. This new seawater greenhouse uses a clever cardboard design to distill fresh water from salt water cheaply and efficiently. It’s helping grow crops in Somaliland, and could help stop the water crisis in Africa and other parts of the world that are susceptible to drought. The founder of Seawater Greenhouse, Charlie Paton, explains how unlike traditional greenhouses - which are hothouses - this one is a “cool house” that is ideal for growing temperate crops in deserts or other hot, arid regions.

The plastic backlash: what's behind our sudden rage – and will it make a difference? | The Guardian

The plastic backlash: what's behind our sudden rage – and will it make a difference? | The Guardian | Geography resources for South African teachers | Scoop.it

13 Nov 2018

Plastic is everywhere, and suddenly we have decided that is a very bad thing. Until recently, plastic enjoyed a sort of anonymity in ubiquity: we were so thoroughly surrounded that we hardly noticed it. You might be surprised to learn, for instance, that today’s cars and planes are, by volume, about 50% plastic. More clothing is made out of polyester and nylon, both plastics, than cotton or wool. Plastic is also used in minute quantities as an adhesive to seal the vast majority of the 60bn teabags used in Britain each year.

Weather will be much warmer by 2050. See how these US cities will change I VOX | Geography resources for South African teachers | Scoop.it

30 Oct 2018

But how much will temperatures in US cities change by 2050? By then, scientists say average global warming since preindustrial levels could be about twice what it is in 2018 — and much more obvious and disruptive.  To answer this question, we looked at the average summer high and winter low temperatures in 1,000 cities in the continental US, comparing recorded and modeled temperatures from 1986 to 2015 to projections for 2036 to 2065. This offers us the best possible estimate on how much winters and summers will shift from 2000 to 2050.

Typhoon Mangkhut has recently wreaked havoc in the Philippines, Hong Kong, Macau, and southern China causing injuries, forced evacuations and agricultural damage in the Philippines. Meanwhile, Hurricane Florence has caused catastrophic flooding in the southeast US. For years, scientists have warned us that climate change will likely lead to bigger, wetter, and more intense storms. But we can’t stand back and let the impacts of climate change become the “new normal”.

Climate change: Five cheap ways to remove CO2 from the atmosphere I BBC

Climate change: Five cheap ways to remove CO2 from the atmosphere I BBC | Geography resources for South African teachers | Scoop.it

26 Oct 2018

As well as rapidly reducing the carbon dioxide that we humans are pumping into the atmosphere in huge amounts, recent scientific assessments of climate change have all suggested that cutting emissions alone will not be enough to keep global temperatures from rising more than 1.5 or 2 degrees C. The Intergovernmental Panel on Climate Change and others have all stated that extracting CO2 from the air will be needed if we are to bend the rising temperature curve before the end of this century. These ideas are controversial with some seeing them as a distraction from the pressing business of limiting emissions of CO2. But a new assessment from the US National Academies of Sciences, Engineering and Medicine says that some of these "negative emissions technologies" are ready to be deployed, on a large scale, right now.

Trading Plastic Trash in Indonesia for Free Transportation I VOA

Published on Oct 27, 2018
It was reported recently that microplastics, both in the ocean and in the plastic all around us, is finding its way into the human body. But the convenience and affordability of plastic means that, for now, the best we can hope to deal with this problem is to improve recycling efforts. Indonesia's second largest city is trying to do just that by offering free rides on the city's bus system in return for plastic trash. VOA's Kevin Enochs reports.
