Finding smart insulation for a hot house

February 29, 2016 1 Comment

Another summer almost over … hope to goodness the worst heat is over. How clueless was the building industry about energy efficiency when most of our houses were built! Who does not want to save energy now – and it is indeed all our duty to relieve the pressure on the national energy supply. Our double storey really cooks upstairs, where we work. Ancient traces of insulation … [Read more...]

Dealing with heat exhaustion and heatstroke

January 12, 2016 Leave a Comment

As we melt our way through the SA's climactic summer, heat exhaustion and heatstroke are two potentially serious conditions that can occur if you get too hot. This overheating can also be caused by  very strenuous physical exercise. Heat exhaustion is where you become very hot and start to lose water or salt from your body, which leads to the symptoms listed below and … [Read more...]

First three months of 2015 were warmest on record

April 17, 2015 Leave a Comment

March this year was the third hottest month in global climate records, according to reports from NASA GISS. The reading — at +0.84 C above the 20th Century average — fell just behind March of 2002 (+0.88 C) and March of 2010 (+0.87 C). With El Nino firing off in the Pacific and polar amplification pushing to ever-greater extremes in the Arctic, 2015 is following hot on the … [Read more...]

Are we learning from the fires?

March 13, 2015 2 Comments

As the fire from Stellenbosch jumps across the Helderberg mountains and spreads down onto the Lourensford estate, Somerset West, everyone’s talking arson.

We know that changing land uses and patterns of dryer and hotter climate has … [Read more...]

Employing aliens to capture carbon

February 20, 2014 Leave a Comment

Imagine turning thirsty alien invasive trees into biochar.  Biochar is charcoal created by pyrolysis of biomass. This differs from charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture. If created under specific conditions it can also be suitable as a soil amendment. In a forest near Pietermaritzburg there is … [Read more...]

Have an Eco-friendly Autumn

have-an-eco-friendly-autumn

Autumn is here and many of us are “nest building” for the cooler season. It’s time to reflect on how we affect the environment with our excessive energy needs and make some changes to lessen the burden we place on the Earth. Winter days in the Midlands are glorious. How fortunate we are to have blue rather than grey skies. It makes keeping warm so much easier – so make sure … [Read more...]
