"Climate scientists struggle to explain warming slowdown,' said Reuters. But warming is speeding up, and scientists can explain it"

"In Economics in Plain English, the new economic explainer video series from The Atlantic, business editor Derek Thompson answers big and small questions selected from hundreds of reader submissions. Up first: Why is bottled water so expensive? In less than three minutes, Thompson explains what goes into the price of bottles, why all water is more expensive than you think, and why the most expensive component in some bottled water is neither the bottle nor the water."

"Bill Gates sees meat alternatives a a big part of the future of food. On his blog, The Gates Notes, there is a feature called The Future of Food, where he explains how food scientists are starting to reinvent meat, and how this could help the whole world. Gate explains that worldwide meat consumption has doubled over the past two decades and is expected to double again by 2050 when, as we know, world population is expected to reach at least 9 billion. It is just over 7 billion now."

"How can putting a price on carbon lower greenhouse gas emissions? Get to grips with the theory of how carbon pricing works."

"Forest ecologists like a challenge however, and there have been several attempts at estimating the forest carbon "sink". According to this analysis, intact forests and those re-growing after disturbance (like harvesting or windthrow) sequestered around 4 billion tonnes of carbon per year over the measurement period - equivalent to almost 60% of emissions from fossil fuel burning and cement production combined."

"To explain the latest 20% rise of electricity cost in Queensland, look no further than the free market reforms kickstarted in the 1990s"

"Demand on wireless networks is climbing as more and more people use their mobile devices to access applications like email and Twitter. It might seem like a carbon neutral activity but Australian researchers estimate that the global energy consumption by wireless networks will grow by 460 per cent over the next two years. In emissions terms, that's the equivalent of 4.9 million extra cars on the road. Professor Rod Tucker is the director of the University of Melbourne's Centre for Energy Efficient Telecommunications, and he explained the impact of the shift to Lexi Metherell."

"As much of inland and eastern Australia sweats through its first heatwave of the summer, a new interactive website has been launched to track where the heat is coming from and to map past heatwaves across the country. Extreme heat has killed more Australians than any other natural hazard in the past 200 years. For example, more people died during the 2009 Victorian heatwave than the Black Saturday bushfires. But as scorcher.org.au explains, a heatwave is more than just one hot day. "

"While the Coalition didn't release a 2013 election policy document explaining how they'd reduce emissions, they did release a document outlining how they'd axe the tax. The document is entitled The Coalition's Policy to Deliver Lower Prices by Scrapping the Carbon Tax. Within it is an excellent idea well worth supporting, in that it will highlight just how 'brilliant' the Abbott government's cost of living 'relief' will be when it axes the carbon tax. "

"Published on 6 May 2015 This 2-minute "explainer" shows how tiny plastic microbeads are designed to go down the drain and into our rivers, lakes, and oceans and we can do to stop this ridiculous assault on our public waters. TAKE ACTION: http://bit.ly/banthebead"

"It has been known for more than 150 years that light can have an effect on the electrical properties of some materials. This is called the photoelectric effect. In 1921, Einstein received the Nobel Prize for his work explaining this. Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity. Let's look at how."

"Measuring Inequality" - various models explained

"Commerce knits the modern world together in a way that nothing else quite does. Almost anything you own these days is the result of a complicated web of global interactions. And there's no better way to depict those interactions and the social and political circumstances that give rise to them than with a map or two. Or in our case, 38. These maps are our favorite way to illustrate the major economic themes facing the world today. Some of them focus on the big picture while others illustrate finer details. The overall portrait that emerges is of a world that's more closely linked than ever before, but still riven by enormous geography-driven differences."

"I would like to know to what extent regenerative agriculture practices could play a role in reducing carbon emissions and producing food, including meat, in the future. From what I have read it seems to offer much, but I am curious about how much difference it would make if all of our farmers moved to this kind of land management practice. Or even most of them. - a question from Virginia"
