Although climate change is a natural occurrence, human industrial and development activities over the past two centuries have caused changes in climate independent from natural changes. Climate change is a slow, natural cycle that causes the earth’s temperature to rise and fall periodically over centuries.
Soil erosion, KwaZulu Natal.
Human intervention, however, has sped up the process and has had catastrophic effects across the globe. All ecosystems and biodiversities are threatened by climate change and its effects are remarkable on all life. Climate change has a profound impact on human life - it influences temperatures shifts, food security, water resources, greenhouse gasses.
This is not a list of impacts we can expect to see as our climate shifts. Rather, it is an opportunity to introduce you to some of the real people of South Africa who will be expected to live through these climatic shifts. Some of these people may even be stripped of their livelihoods as a result, even though their contribution to the pollution which causes the problem is close to negligible.

The Cape coastline faces into a turbulent ocean. Climate change will make this naturally stormy sea all the more formidable. Increasingly stormy seas and higher sea levels are beginning to show up the existing fault lines...more

As long as Earth has been shrouded in a thin layer of gas, its climate has shifted and swayed between different states in response to entirely natural cues from the sun and our orbit around the sun, from the albedo effect, in response to how thick the bla...more
Over in the Western Cape, where the finger of climate change is already pressing down on the pulse of agriculture, farmers know that their land cannot support another 2°C increase in temperature, further rainfall loss or shift of seasons....more

In 2004, scientists looked at records from 26 weather stations across the country and calculated about a half degree average increase since 1960 (specifically, an average 0.13°C increase per decade), with both minimum and maximum average temperatures ref...more
One tipping point, hidden away in the ocean, could bring a mini ice age to Europe. It sounds counter-intuitive, a regional ice age in the midst of global warming but if Greenland’s ice continues to melt, it’ll probably happen....more
Carbon “sinks”, in the shape of forests and the ocean, strip about 40 percent of our annual CO2 emissions from the atmosphere....more
A warmer atmosphere can hold more water vapour, and since the 1980s the average atmospheric water vapour content has increased....more
Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level....more
The shifts in climate which we’ve seen in recent decades will continue into the future and, in most cases, escalate....more
Through the years, climate change has not only endangered all living ecosystems, biospheres and individual species, but their food supply as well. Increased droughts, wildfires and decreased rainfall has greatly influenced how the world produces food....more

South Africa has seven distinct plant communities – desert, forest, fynbos, grassland, Nama-karoo, savanna and succulent karoo – and since their natural range reflects the climatic envelope of the biome, it made sense to use climate modelling to see how....more

South Africa’s staple, maize, has many faces: a bowl of sadza or umphokoqo with beans; lumps of iphuthu, moulded into the hand and dipped into meaty sauce, krummelpap with melted butter, sugar and milk; boiled mealie or braaied sweetcorn....more
