On Monday, COP 22 – the 22nd Conference of the Parties to the United Nations Framework Convention on Climate Change – began in Marrakech, Morocco. Unlike last year’s event in Paris, this climate summit has received little publicity. There is hardly a mention of it in the mainstream media. Even the fact that the Paris agreement came into force last week (with the backing of both US and Chinese presidents, representing the two largest emitters of CO2) made little splash. Even if it had, the world woke up two days after the jamboree had started to the unexpected (and, to some, shocking) news...

In 1989, two physicists – Martin Fleischmann and Stanley Pons – held a press conference to reveal an experiment that apparently demonstrated nuclear fusion at room temperature. Understandably, this caused a furore in the scientific world, but after the hype came the consensus that this was essentially a con. In fact, the situation is much more complicated than a simple case of poorly-designed experiments, misinterpretation or even scientific fraud. One of the problems was the name given to the observed phenomenon, cold fusion. The suggestion that atomic nuclei could be made to fuse and...

An intense El Niño event has raised global average temperatures recently, in the same way as the spike in 1998. But all the indications are that the Pacific is turning towards La Niña conditions, which will depress temperatures for the next year or so. It is too early to tell what trend we will see after that part of the ocean has settled back to ‘normal’, but these spikes appear to be superimposed on an essentially steady average temperature. This, however, is not what you would think if you read recent headlines about the most recently published measurements of atmospheric carbon dioxide...

Two major UK travel infrastructure projects are slowly edging towards realisation. One is HS2, which is looking increasingly like an extremely expensive way to add extra capacity on the West Coast mainline, affordable only to business travellers; the other is a third runway at Heathrow, to give London’s main airport a fighting chance of remaining a key international hub. While experience shows we are not necessarily the worst at completing such projects – Heathrow Terminal 5 and the Olympic Park were built to schedule, unlike Berlin’s new airport and Stuttgart’s new station – we often seem to...

If cutting greenhouse gas emissions is as important as is claimed, there are two main ways to do it: stop using fossil fuels as soon as possible, or continue to burn them while viable alternative energy sources are developed, and remove and lock up the resulting carbon dioxide. Carbon Capture and Storage (CCS) still has its supporters, despite a singular failure to upscale in any way that could be easily rolled out on the vast scale needed. But, if – and it’s a big if – a recent report is true, then this outlook could change. The report on the Independent website certainly hypes up one...

Consumer prices for gas and electricity have to cover various fixed costs – the distribution network, maintenance, metering, administration etc – but are determined primarily by market prices for fuel. With oil, coal and gas prices being relatively low, Europeans should normally be looking forward to a period of stable or even falling utility bills. However, climate change policy has changed this situation. By requiring suppliers to generate increasing proportions of electricity from renewables – wind in particular – and by effectively taxing the use of fossil fuels, prices are being...

The old adage that good news isn’t really news today seems truer than ever. Bad news is reported rapidly across the internet and social media, and there are unfortunately relatively few good news stories that command as much attention. Something such as the Olympics is the exception. But it’s not just current news that is generally bad; increasingly we see dire predictions about the future. In fact, perhaps this has always been the case. After all, think how much science fiction envisages a dystopian future. Computer modelling, which is the source of most of the current stories, uses...

It seems that the UK’s first new nuclear power station for a generation – Hinkley Point C – will finally be built (Hinkley Point C finally gets green light as government approves deal with EDF and China). The deal has been widely criticised, but it still has its supporters. So, at this critical stage, it is worth trying to put this key part of the country’s future energy infrastructure into context. With the benefit of hindsight, it is probably not something that any of the parties involved would want to start from scratch now. But we are where we are, and the project has to be viewed in...

Carbon Capture and Storage (CCS) sounds simple, but is very complex to put into effect. But it remains a potentially attractive policy option for one key reason: its successful introduction would allow us to burn more gas – and even coal – while reducing carbon dioxide emissions. It is certainly an attractive concept, but it comes at a cost, and no-one has yet turned it into a successful process that can be built into power stations on a routine basis. The capturing part is quite straightforward. Flue gases from burning fossil fuels are passed through a solution of amines that combine...

At the recent G20 meeting in Hangzhou, Presidents Obama and Xi announced that they would be ratifying the climate deal reached in Paris last December. Superficially, this is a big deal – if the two largest global emitters of carbon dioxide are prepared to sign up to this agreement, others will surely follow – but is it really going to make a difference? The main reason this is significant is that, for the first time, it potentially brings all countries into a global agreement to reduce emissions. The Kyoto Protocol, the only previous binding commitment, included only industrialised...
