How we are changing the climate, and climate is changing the world we live in



The following graphic was created by learnstuff.com. It paints a dramatic
picture of climate change, and our role in it. What the consequences
will be remain a matter of educated speculation, and will depend on
where one is on the planet. Polar regions are already experiencing
much higher temperatures compared to the historical record, while the
impact around tropical regions may be buffered for a while. Either
way, its good to remind oneself of the potential consequences, and to
think about ones behaviour, consumption patterns (of food and goods)
and goad ourselves into trying to make a difference – for the future
of our children and all the other residents of our beautiful planet.

Beware the beautiful Boomslang!


It was transect time again today; and my destination was the Blue Hill boundary with the Baviaanskloof on the ridge of the Kouga mountains. This is one of my favourite routes as it is high – over 1400m for most of it, with views north to the Swartberg, west to the Kammanassie, and south to the Tsitsikamma mountains and there is always something to see. Its just usually not a snake, and especially not a boomslang as most of the vegetation up there has just turned one year old and, well, there are just no trees anywhere. Probably haven't been for many years!

It was a hot day. In fact, my first snake of the day was an unidentified colubrid hiding in the grass that I couldn't get a good photo of. But then as per usual I was distracted by birds or simply trying to find my way up the mountain slope over loose rocks and charred skeletal remains of proteas and the thought of snakes left my mind.

So the dry rasping and flash of yellow glimpsed out of the corner of my eye caught me by surprise, and I had to take a step back in a moment of nervous panic as the boomslang lifted itself off the ground like a cobra, only meters from me. I stood entranced as it swayed from side to side. It was almost as if it was the snake charmer and I was the snake. The big eyes, puffed up neck, darting tongue were mesmerising. Then I remembered my camera in my backpack and I managed these photos of its warning dance before it took shelter under a rock.

With these bright colours, it has to be a male. It was probably 1.5 meters long. Bites are rare – but with hemotoxic venom that stops the blood clotting and can result in internal bleeding, one doesn't want to get bitten as monovalent antivenom is hard to come by and treatment may involve total blood transfusions.
