How to build a green roofed garden store

Since I laid out my slate patio a few years back I’ve used it less than expected. I realised lack of storage was one reason for this. Along with the inevitable broken flower pots and recycling bins, the odd bag of rubble or scrap of wood temporarily parked until the next recycling centre trip was giving my back garden a builder’s yard vibe!

Instead of storing my rubbish in an ugly plastic box, I built my own green roofed garden store. I chose Sedum turf instead of wildflower because although both encourage pollinating insects, as Sedums are semi-evergreen they give you something to look at through the winter as well as summer.

Climate change, anxieties and actions

This summer’s heatwave through Europe and Asia was one of many extraordinary weather events, which along with forest fires, storms and flash floods, are becoming less extraordinary every year. Scientists are not claiming direct cause and effect for individual weather events, rather there is a very simple principle at work – CO2 and Methane put more energy into our weather systems. The more energy goes in, the more energy comes out, with greater frequency and intensity of extreme weather events.

The IPCC October 2018 report and the ‘hothouse earth’ report that rounded off the summer both re-state that climate change may become irreversible, but with the worrying twist that the tipping point may be closer than previously thought. There are more frequent warnings that we really could leave Earth permanently damaged for our species, perhaps within a few generations.

Such headlines grab the attention for a time because our hunter-gatherer brains are hardwired to monitor for immediate threats. However as the solution requires action outside of our control, what remains is often a sense of powerlessness.

Those of us who grew up in the shadow of the nuclear arms race lived with a similar sense of anxiety and powerlessness. Every childhood from the 1950s to the 1980s came with the realisation that the complete destruction of everything you love is an ever present man-made threat. The adult world is dominated by a love of abstract concepts – political ideology then, short term profit now – which become more important than life on this planet.

Yet, despite our species many flaws, we have to focus on the positives and believe our species has a strong enough instinct for self preservation to avoid complete catastrophe.

BioDiesel. The Good, the Bad, and the Chippy

I do around 2000 miles per year by car. To further reduce carbon emissions and air pollution I’ve been filling up my Golf Tdi mk4 with recycled food oil biodiesel. Crops grown for Biofuels compete with food production for land and water. However recycling food oil into fuel should not be dismissed as it reduces carbon and generally burns more cleanly than standard mineral diesel.

In use I’ve found no loss of power and the engine runs as smoothly as before, if not slightly better. Because biodiesel contains more Oxygen and cleans deposits from your fuel system, it’s recommended to change the fuel filter after the first 1000 miles. My 2002 Golf Tdi is well suited to running 100% biodiesel. Continue reading…

Public transport – an alternate route?

Public transport is the most efficient way to move people around our cities, so why is it not more widely used? In many UK cities people use their public transport unwillingly. Increased privatisation has not fixed the problem. Outside of London bus passenger numbers have been in sharp decline since 1984/85, down 37%. And privatisation continues – the (ironically delayed) 2017 Bus Services Bill introduced a wholly ideological clause to stop local authorities running their own bus services, even if that service is more cost effective than a privately run service.

Efficient public transport is vital to our environment and our economy, and I believe our overly privatised buses and trains are failing on both counts. Here I’m going to suggest a way to enable low cost public transport across the UK to improve our environment and increase passenger numbers. Continue reading…
