Climate scientists have spotted warning signs of the Gulf stream collapse

For many years there has been concern about what will happen to the various ocean currents, as the earth and the oceans warm. One of the currents that has the biggest positive effect is the Gulf stream – and scientists warn that the loss of this current could have devastating effects on the world and must not be allowed to happen.

Unfortunately, we are not changing our habits very much at all, and certainly not fast enough.

There are more than 10,000 tigers living in the USA, with under 4000 in the wild

Back in 2010, the 12 tiger countries in the world came together with an aim to double their tiger population by 2022 the next year of the tiger. This has failed and I will write about it in an article coming out tomorrow.

However, perhaps more alarming, there is currently almost 3 times as many tigers living in private collections in the USA than there are in the wild. Even with 12 years of hard work and much money spent the wild tiger population has increased to 3,900, yet in back yards across the USA there are estimated to be 10,000. Now some estimates are lower with the WWF estimating 5000 -though even this low estimate is still lower than the total in the wild. Importantly only 6% of these tigers are kept in facilities that are accredited as zoos, and the rest usually have no one who knows how to work with them. One of the problem with this, is that much of the USA tiger trade is there to provide tiger bones for traditional Chinese medicine.

While some of these are carefully looked after and are only bred amongst their own sub-species, others are are treated essentially as a large pussy cat. Why is keeping their sub-species pure? If captive tigers are to form a protective net against wild extinction, they must be capable of returning to the wild. For this we need each subspecies to remain genetically pure, so that they are able to retain their adaptions for each environment. If for instance, a Bengal tiger from India was released into the Siberian tiger range it would be unlikely to survive as it would not be able to cope with the cold. On the other hand, if the Bengal tiger was released in Sumatra, it could do great damage to the ecosystem as it is so much larger than the native tiger.

Although tigers are listed as endangered under the federal Endangered Species Act, the law still allows private possession of captive-bred tigers as long as they are used for conservation. Precisely how the US authorities can enforce this is anyone’s guess. Clearly, the majority of US tigers have nothing to do with conservation.

The fact that there are so many tigers in the USA can therefore be a threat to the long-term survival of wild tigers. However, it would seem that it is also a big threat to the survival of the Jaguar. Jaguar canines sell for $200-$300 in south America. However, sold in china as tiger teeth, they can go for $5000-$10,000. As a result, this tiger pet industry in the USA can lead to the destruction of not only tigers, but also Jaguars.

What is clear, is that the USA needs to get a grip in its domestic exotic pet trade and fast. There is no place for a big cat in someone’s home. If things continue to go as they are, USA will not only be responsible for much game hunting around the world, but could also lead to the extinction of other species to supply the pet trade.

Montana has moved to limit wolf hunts after more than intended, but commissioners won’t reinstate quota ended by Republicans

The rules about hunting around Yellowstone, are like elsewhere quite absurd. When the animals roam across an arbitrary line, they can be shot. One side is fully protected land, the other side open season.

Now it is encouraging that the wolf hunt has ended early. The commission vote (passed unanimously) made a rule that hunting and trapping would end when 82 animals had been killed (76 had died at the time).

23 wolves from park packs have been killed this year – more than in any season since wolves were reintroduced 25 years ago.

Bears should be given more respect as predators

It is often suggested that bears are merely opportunistic when it comes to meat eating. The suggestion is that bears are vegetarians who are capable of scavenging from dead animals.

Now, of course we need to be careful as bears have a wide range of intelligences. Brown bears have an intelligence on par with chimpanzees, where as black bears are far less bright (though they are still one of the brightest animals).

How can California be so stupid?

California is known for its forward thinking views on climate change. They have taken some of the biggest steps towards decarbonising, and being a country that receives a great deal of sun have the potential to make more electricity than they need, completely from green sources.

1.3 million houses already have solar. The California Public Utilities Commission is considering taxing everyone $8 per month per kilowatt of solar installed. Nothing else would change – for people with large arrays, they could have to pay $1000 dollars a year.

This has been a main aim for utilities for years. It is quite understandable. If for 5-10 thousand dollars you can create a solar array on your roof, which means that you become close to self sustaining the utility companies loose their market share. Furthermore, if they are required to pay for exported solar, then that eats into their profits. This of course is despite the fact that this solar exported is clean energy so is good for the planet.

The argument is that this money will go for upkeep of the grid, and that the customers are getting free use of the grid. Now there are several issues with this.

Firstly, this move is likely to push many people with batteries to go further off grid. This will hit utilities hard. Now not only will they not get cheap electricity but they will also not be able to supply night time power. However there is another issue. A connection to the grid once there does not cost a lot to maintain – also, whether exporting 1kw or 10kw the same wires is used. Therefore, the pricing if one was needed should be flat ($8 flat per month seems far more reasonable- $8 per kwh suggests the states are giving utilities the means to squash small energy suppliers.

Are big power companies going to be charged this as well? because if you are going to go to this system they must be. The Diablo Canyon Power Plant is 2256megawatt output, if we were to charge the same thing then they would have to pay slightly over $18 million a year. This is something that even on a large nuclear plant would threaten their future finances.

There is still a coal powered station in California, and 41mw of gas powerplant.

Powerplants which are still using fossil fuels should be forced out of business – this foolish move will likely greatly reduce the rollout of solar in the country, which would lead to problems. Indeed, this state is aiming for 100% green electricity by 2045, which means that they need all the solar they can get.

This is a foolish move and is likely to either damage California’s future, or will be reversed in the future. I feel that it is extremely similar allowing petrol stations to charge electric cars for their lost business.

Another thing that should be recognized, is that as the grid improves more and more power will be consumed locally. For most houses with solar panels, any power they export are used by their neighbours. In other words, Solar panel owners, use a few hundred meters of cabling, while the utility companies are sending power over thousands of miles.

Looking at countries which are learning to live with the wolf after a century if its absence

Wolves returned to the Czech republic after a centuries absence in 2014. Why is this of interest? Well, there are areas across the USA which have been missing the wolf for one hundred years, so it is worth watching to see how they adjust. The Czech republic does still have forest cover of around 34% meaning that there is plenty of territory.

In the 7 years since, wolves have done well with the population currently estimated at 50-80.

They are currently generally accepted back, as they bring in significant money from tourism.

Now the Czech republic is not a small country, but wolves were pushed to extinction and this despite large areas of forest.

In a similar way, bears were wiped out. Sightings have become more common, and if hunting pressure is reduced they are likely to recolonize. There is a stable population of 600-800 in Slovakia.

I hope to add places to stay, as tourism with greatly help in encouraging this country that it is financially worth it, to have these animals close by.

Another foolish article about the superiority of ICE vehicles over Electric

The horrific traffic catastrophe in Virginia in the ice has lead to another foolish article about the supremacy of ICE over electric.

I havent heard of the author Charles Lane but the article is similar to dozens I have read in the past “here is an anecdotal situation that occurred to me, doesnt it show how electric cars are rubbish”.

Vehicles are seen on an icy stretch of Interstate 95 closed as a storm blankets the U.S. region in snow. Are you really better in an ICE vehicle than an electric?

In this situation a 48 mile traffic jam appeared on the interstate 95 in Virginia. A trucker found his cab door being knocked on by a woman who was in an electric car and hadnt enough food or water. They were worried about running out of charge while trying to keep their vehicle warm. With kids in the car they had got out to ask other vehicle drivers for blankets or anything else (outside temperatures were minus 7 degrees).

So why was this a foolish article to write? Essentially the lorry driver is saying, look at this situation where ICE cars were better than electric, therefore no-one should buy electric.

So lets look at this situation.

1 Given an electric car can be charged at home, and an ICE vehicle needs refilling at a fuel station, which is most likely to be near full of fuel in an emergency? Many people do a small top-up every night so keep their car at around 85% permanently, except when going on a long journey. Generally people only refill their tank when it is nearing empty.

2 Electric cars are almost 100% efficient with a heat pump as many of these cars use. A tesla 3 heat pump could keep its inhabitants warm for 36 hours on a full charge. In an ICE car it would entirely depend on how recently it was refilled- depending on the size and efficiency idling fuel usage can be anything from 1 litre an hour in a small car, up to as much as 5 or more in a big car (or a sports car like a dodge viper). A Hyundai Kona uses about 1 litre an hour and has a tank of 38 litres, so would last about a day and a half. Even in big cars the fuel tank is not normally bigger than 70 litres, which would suggest 14 hours,

As such, in actual fact the odds of running out of fuel (charge or gas) in a sticky situation is likely to be far higher in an ICE vehicle. Once in the situation, unless you are in the right car for this rare situation, electric is far more likely to safely keep you warm till the road clears.

Now it is true that should your electric car drain completely to zero, it is more bother to recharge an electric car than it is an ICE vehicle, as the latter merely needs a walk to the nearest petrol station. Why do so many writers grab every chance to take a swipe at electric? Probably because they know that they will be paid well – however as these stories start to look more and more stupid, I think it is going to be harder to find someone to write your hit piece.

Lockdown has shown the perils of overreliance on tourism: what to do

Uganda has suffered during lockdown. As much as 7% of the countries population works in tourism, a sector which has been either totally shut down, or greatly reduced over the last few years. Several other countries like Tanzania have suffered in a similar way.

To protect some of the most special wildernesses in the world we need a better system

How can we expect countries to protect huge ecosystems if the income to protect them can dry up with no warning?

Bears and wolves are not good friends seen recently as bear steals a kill from wolves in Yellowstone

Most scavengers are relatively small. Animals like jackals are unable to make large kills. Furthermore, the amount left behind by lion and leopard is usually more than enough for a jackal to survive on.

In the northern hemisphere though, bears get a great deal of their calories from scavenging. They have an incredibly keen sense of smell, allowing them to find dead animals,

However unlike the jackal, they are very capable of hunting. They can be seen from time to time, mixing the two.

A bear runs along with a wolf pack, and then steal the price

Bears, particularly Grizzly bears, are very strong. In peak health, a large bear is more than capable of taking on a pack of wolves. They also require huge quantities of calories, and before going into hibernation, this will often push them to take bigger and bigger risks.

This is not hugely rare behaviour, but it is far rarer that it be filmed.
