Environment

Though environmental activists are aghast that Republicans now control the White House, the Senate and the House for the first time since the 1920s, at least a few have come to some self-awareness that non-stop lobbying against jobs and poor people, and for higher regulations and cost, are to blame for why their candidate lost.

What they don't realize is that there is actually a great deal of opportunity for environmentalists during the Trump years. In most ways, he is a lot more like Democrats than he is like Republicans, they just need to stop being against everyone and everything except higher taxes and more federal rules.

It may be time to mix it up, when the writing is on the wall that being "anti-" is not working for anything except their bank statements.

How can we predict the climate so far ahead when we can't do an accurate weather forecast even ten days ahead? Well it is remarkable that we can forecast our weather even one day ahead, and by looking at how the forecasters do that we can begin to understand how the models can work over longer timescales. When I was a child in the UK in the 1960s, with our unpredictable weather, a cautious person would take rain gear with them almost no matter what the forecasters said. Even as late as 1987 we had Michael Fish's famous weather blooper. This broadcast is so famous here that it starred in the Olympics 2012 opening ceremony.

Step 1 - we humans discover that the Arctic accumulates more heat on a summer's day then the equatorial regions.

Step 2 - we realise that our atmosphere is heated not so much directly by the sun but by heat from the surface.

Step 3 - we discover that heat and light are two separate forms of radiant energy

Donald Trump has just been elected as US president, as a Republican climate skeptic. So if you are from the US you may get the impression that this is a political debate between “lefties” who think climate change is real and “righties” who think it isn’t. But it’s only in the US that there still is a political debate at all. Here in the UK for instance it has cross party support, and we have a right wing government who have just ratified the treaty. For us, it was a matter for debate a decade or two ago, but the debate was already over some years back. We've decided action is needed, and there were many things we could have done, but the main thing was to do something, and the Paris agreement was what they came up with.

A mathematical model that assists in decision-making at a facility devoted to the cultivation and production of the common mushroom (Agaricus bisporus) has received the prize for the best scientific contribution during the 2nd International Food Operations&Processing Simulation Workshop, FoodOPS, held in Larnaca (Cyprus).

Environmental Defense Fund (EDF), one of the nation's largest environmental groups, which has been bankrolled with $50 million from the heirs to the Walmart fortune, has spent millions of dollars pushing a wholesale change in how the U.S. manages its fisheries, to the detriment of fishermen and with no benefit to nature

In a Youtube video that has been viewed more than 25 million times,  George Monbiot explains with masterful clarity How Wolves Change Rivers. The short film tells the story of Yellowstone National Park, where wolves were reintroduced in 1995 after an absence of 70 years. Heralded as a successful example of "trophic rewilding" (Svenning et al 2015) - whereby missing "trophic levels" in the food pyramid are re-installed to exert top-down control- the returning wolves are credited with controlling numbers and behaviour of herbivores (elk), thereby allowing vegetation to return.

Over the past few weeks there have a been a series of reports raising concerns about the felling of old-growth trees in the ancient Bialowiezça forest in eastern Poland. A recent piece in the Guardian begins

My last post dealt with the permaculture edible forest garden, and it received some commentary on a couple of Facebook groups and permaculture forums.

A lot of the responses were, predictably, from permaculture advocates who took umbrage at my having deigned to critique their philosophy at all, but there was one very valid criticism concerning yields: while I had compared weights of different crops per acre, a more useful approach would be to compare calorific yield.

Doing this for the crops I listed gives a result looking something like this:
