Researchers find the daily migrations of brine shrimp is strong enough to mix ocean waters

When we think of global warming and climate change, most of us ignore the impacts that animals have on the environment. Climate affects animals, but is the reverse true? Can animals affect the climate?

I don’t know how to answer that question definitively, but I was fortunate enough to read a very recent paper from a top fluid dynamics research team from Stanford. The team, led by Dr. John Dabiri, is well known for their work on bio-inspired flow. Part of what they study is the influence of living organisms on fluid flow, especially flow of water in the oceans.

Ocean dynamics are directly connected to global climate through interactions with the atmosphere. The fact that swimming animals could play a significant role in ocean mixing – an idea that has been almost heretical in oceanography – could therefore have consequences far beyond the immediate waters where the animals reside.

Shoreline communities may be inundated in the next two years as ocean levels rise amid serious climate change concerns

The frequency of coastal flooding from high tides has doubled in the US in just 30 years, with communities near shorelines warned that the next two years are set to be punctuated by particularly severe inundations, as ocean levels continue to rise amid serious global climate change concerns.

The decision to go ahead with the third runway at Heathrow was taken two years ago; Chris Grayling’s confirmation yesterday marked the point when it seemed to its promoters that enough of the opposition on the ground had been defeated, so it was safe to proceed with a final vote in three weeks’ time. If that is won, and all goes according to plan, the bulldozers will go in around 2021, when the inevitable cycle of cost overruns and slipping deadlines can begin, 31 years after the project was first mooted. By then the UK may be two years into a lengthy “transitional” post-Brexit period, and the bright economic forecasts which are used to justify the plan may be no more use than hot air balloons.

There is a case that air travel has made life better for many people and that more of it would continue to do so. Nearly two-thirds of Heathrow’s present traffic is leisure flying. Mass tourism has boosted the economy of many countries and greatly enlarged our experience of the world, and perhaps our sympathies as well. However unpleasant the experience of a modern airport can be, through which we are run like rats in a maze of shopping malls and security checks, it still seems better to many of us than being trapped in our own countries all year round. Heathrow as it stands today is an unimposing portal to Britain. Failing to expand it is simply sabotaging the country. Beyond that, the country is dependent, like all others, on air freight. So the plans for expansion are in some ways well motivated. We can even overlook the fact that they are promoted by Mr Grayling, a man notoriously unable to make even trains run on time.

As the world moves towards a low-carbon economy, fossil fuel investments worth trillions of dollars, from oil wells to cars, will lose their value

Investments amounting to trillions of dollars in fossil fuels – coal mines, oil wells, power stations, conventional vehicles – will lose their value when the world moves decisively to a low-carbon economy. Fossil fuel reserves and production facilities will become stranded assets, having absorbed capital but unable to be used to make a profit. This carbon bubble has been estimated at between $1tn and $4tn (£3tn), a large chunk of the global economy’s balance sheet.
