Professor Pete Smith will be providing a talk entitled:

“Limiting Climate Change”

On Saturday the 11th October at 11:00 am.

At the Belmont Picture House Café Bar, Aberdeen.

Hydrogen Buses in Europe’s Oil Capital

Aberdeen-hydrogen-bus-copyright-Aberdeen-city-council_3I was quite impressed to learn the other day that Aberdeen City Council are building the country’s first Hydrogen Power Plant. This 1MW plant will be used to fuel 10 hydrogen powered buses which are being rolled out over the next 18 months. Hydrogen powered vehicles only emit water vapour and are quieter and smoother in their operation. You can read more about this and the Aberdeen Hydrogen project at Invest Aberdeen.


My Hydrogen Fuel Cell – Part 1

Now that I have my workshop up and running (apart from some teething problems with the door – curse you joiners!), it’s time to start on a few projects. First up – hydrogen fuel cells. these cells have always intrigued me because on the surface they seem like energy for nothing – or nearly nothing. Also, a basic cell is easy to build with materials you can find around the house. Here I look at generating hydrogen through electrolysis – the first part of the process.


CO2 Levels Up!

CO2 levels are up by their highest rate since 1984! Concentrations are at 396 ppm (parts per million) according to the WMO (World Meteorological Organisation).


CO2 Cost of Running a Laptop

Not my info graphic – it came through but the author is unknown – so let me know if this is yours and I’ll give credit where credit is due. I can’t see how stopping eating meat will reduce CO2 emissions? Anyone got any thoughts? Post them in the comments? Presumably red meat increases our botty burps resulting in increased methane output! I thought that was vegetables!


The Ice Bucket is Leaking

On August 18th 2014, Facebook told TIME that 2.4 million Ice bucket challenges had taken place – a figure which had more than doubled from 1.2 million in 5 days! When I sent a friend a picture of me doing the IBC they commented that it was a huge waste of water (sometimes you can’t do right for doing wrong). But, speaking globally, is this a significant waste of our fresh water resource?

Scientists Fear

My friend and colleague Erik Dalhuijsen passed along a link to this website in which a number of scientists express their fears about climate change. It’s quite a sobering read but there is an element of hope attached for each of the stories of fear. In particular I liked what Will Steffen, an Earth System Scientist at the University of Florida, University of Missouri and Australian National University had to say:

The thing people don’t realise, is getting emissions down is not only feasible but economically promising and will actually lead to a better life. The narrative needs to change, it’s not all doom and gloom. Yes, it will be another massive transformation in human history, but it will lead to a cleaner environment, to more jobs, and an easier lifestyle.
