At the moment, failing a dramatic increase in political commitment from world leaders, the world’s current and likely future carbon emissions will create at least three degrees of warming. Scientists believe this warming is likely to cause the final disappearance of the Arctic icecap by 2030, severe droughts, heat waves and wildfires in Southern Africa, the possible disappearance of much of the Amazon rainforest, and acidification of oceans, in turn likely destroying much marine life.

These consequences would have dramatic effects on human well-being, and in Southern Africa are likely to lead to increased food insecurity, droughts, an increased number of extreme weather events, increased disease burdens and probable increases in migration and conflicts, not to mention complex economic knock-on effects as climate change and sharply increasing energy costs force dramatic change in the world economy.

Southern African countries can prepare themselves for the consequences of climate change by developing human capital, reducing dependence on fossil fuels, increasing energy efficiency and renewable energy use. It will be vital to make agriculture more sustainable: less water and energy intensive. The region should simultaneously fight in international negotiations for emissions cuts by both rich and developing countries that match what is required by science to stop dangerous climate change.

‘Southern Africa in for 10°C temperature rise’

Without global cuts in carbon emissions, Southern Africa could see average temperature increases as high as 10 degrees centigrade as soon as 2060, according to a study released by the UK’s Meteorological Office last week.

The study is a based on a range of models, and predicts an average global temperature increase of four degrees centigrade by 2060. But four degrees is just the global average increase – and while some areas will warm by less than 4 °C, others will warm by more. For southern Africa, a likely 10 degrees rise is likely in inland areas.

According to Michael Sanderson, co-author of the Met Office report, “The exact impacts of such a large temperature rise on South Africa were not addressed in this study. However, food production will be adversely affected. The temperature rise will decrease crop productivity and increase the risk of hunger.  Some plants and animal species will Continue reading
