A 200 square km seagrass bed has been found to be 1 single plant

Generally, when you encounter grass, or indeed sea grass, it appears to be many millions of individual plants all growing together.

sea grasses form essential habitats for marine life, but entire seagrass meadows usually represent many plants not one

Scientists discovered one single seagrass plant which has spread over 200 square km, and is thought to be 4500 years old.

This huge single plant now provides a place to live and feed for vast numbers of crabs, fish, turtles, dolphins and dugongs.

Bramble Cay melomys have become the first mammal lost exclusively to climate change

A melomy bramble cay

No one knows how the melomys got to Bramble cay a small island 31 miles off the coast of Papua New Guinea, but they did. In 2015 they became the first mammal to go extinct purely as a result of climate change, as their little island home at the end of the great barrier reef sink beneath the waves.

In 1978 a few hundred were counted, in 1998 just 100. In 2002 and 2004 just a few dozen were found. The amount of lady plants shrink by 97% between 2004-2014, and when a survey was carried out in 2014 no specimens could be found.

UK closing in on half a million electric cars

Electric cars appear to be accelerating in their adoption. The UK is close to having more than half a million electric cars on its roads (currently about 477,000). One could add to this the roughly 348,000 hybrid cars, but these are a half way step, and it entirely depends on how they are used, as to whether they end up being cleaner or not. Never-the-less the number of cars in the UK that can drive at least a little distance on zero emissions is approaching 1 million.

With 32.5 million cars in the UK, and not yet 500,000 electric cars, is this all most of them are suitable for?

Large thriving network of settlements thrived in Columbian Amazon before European settlers

Both the Amazon and the Congo have been given the status of totally virgin rainforest, without any human impact. What is becoming increasingly clear is that this is not the case.

Instead it is the case, that the communities which lived here -sometimes in large numbers, lived in balance with the environment.

Pre Columbian settlement evidence in the Amazon

Archaeologists have found vast network of settlements in the Columbian Amazon, spanning hundreds or even thousands of square km, consisting of a main settlement with huge platforms, and smaller settlements spread out around. All are linked by causeways, and canals and reservoirs dotted the land to make agriculture possible.

To be sure, these settlements were low density, but they successfully lived in harmony with the rainforest for centuries.

Oddly, while these communities prospered for 1000 years, they disappeared before Columbus arrived, and it is not clear why.

How should this impact work these days? I am not sure. There are no large groups of modern people who have learnt to live in harmony with their environment, but clearly bush people have. Perhaps we need to follow their example – though the current indigenous people of the Amazon do not live in settlements of large size, otherwise we would have know about these centuries ago,

A group of former UN leaders is warning our pledges aren’t enough on climate change

Current worldwide pledges on carbon dioxide reduction are no where near enough and would lead to catastrophe.

Last year commonsense was found. It was recognized that global warming of 2 degrees will lead to a horrific situation, and that we need to be aiming for 1.5 maximum degree warming. This has been agreed, but at cop26 the pledges gathered were just enough to limit warming to a maximum of 2 degrees.

Unfortunately, actions taken (those pledges that are actually changing behaviour) fall far behind promises, leaving us on target for 2.7 degrees of warming – the upper band suggests 3.6 degrees of warming is still possible.

Developed countries around the world are not acting fast enough. They are also failing to supply funds promised to help the developing world cut their emissions.

Importantly delay will increase the cost. If we fail to act now, actions in the future could be 10-100 times more expensive


UK government gives go ahead for shell to develop a new gasfield

As if we need any examples of the contradictory actions of rich governments, the UK government is still giving permission for new had fields to be created.

It is known that if we are to keep warning to 1.5 degrees or less, more than 50% of fossil fuels must remain in the ground. As such this move is foolish.

The government could do as much for consumer bills by bringing back the green housing grants-and funding it properly. Many people in the country can afford to do the work themselves but many more don’t stand a chance.

Some time, I wrote about the the collective, they might finally be ready to launch

As much as half the particulate emissions from a car, come from they tyres. While electric cars are far cleaner, this particulate emissions is particularly dangerous, to health so this move to do something about it is very good.

The idea is that a device is placed behind each wheel, and is statically charged, allowing it to collect most of the waste. The waste can then be recycled into tyres of into other things. Tyre wear accounts for about 28% of oceanic micro plastics, so it is an area we need to deal with – particularly because with their heavy battery electric vehicles wear down tyres much faster.

Most drivers on petrol engine cars, wouldn’t dream of driving without a catalytic converter – hopefully in the future the same will be said for tyre dust collectors. They should be on the market in the next few years.

Cheetah on the brink of extinction again

I don’t know what your feelings towards cheetah, for many of not most people they have vague idea of the cheetah because it’s the fastest animal on earth. My family have a model cheetah, full size, something I’ve always loved – and it built a deep love for these animals. I was lucky enough to see one whole in the Kruger – not many at the time, so very lucky. I hope this time we will see more

Cheetah running at speed

However, for perhaps most they know little else. I have written on them many times, I believe they are an essential tool for conservation. Given their size, they don’t generally attack humans, and kill livestock far less. Having a historic range that encompasses most of Africa and much of Asia, there are many places they could be, but instead they face extinction once again.

A new study finds that nearly half the worlds land needs to be given some sort of conservation to halt biodiversity loss

This study has found that if 44% of the worlds land surface was given increased protection, then we could save many of the current 1 million species threatened with extinction.

While this accounts for almost half of the world land surface, 1.8 billion people live on this land. While this is a large number of people, it is only 23% of the worlds population.

Much of this land is already protected in some way, but roughly 12.4 million square miles would need to be added (around 20% of the land that was identified). About 70% of the land needed to be preserved is in a largely untouched state – unfortunately though, this is not likely to be the case for long if something is not done.

How this is done, while allowing these people to raise their standard of living is a big issue, but it is one we need to solve, if we are to leave our world in a good state for future generations.

15 wolves have now settled in Netherlands with another 11 visitors

While many people suggested that countries like Holland are far to built up to ever have a population of wolves, this is becoming increasingly clear to be wrong. 15 wolves have not only settled in Holland, but have established territory. This includes 4 pairs, which are likely to have cubs later in this year.
