Human influence on the climate system is clear. This is evident in most regions of the globe, a new assessment by the Intergovernmental Panel on Climate Change (IPCC) concludes.

"The only logical conclusion to draw from an understanding of the science of climate change, as described in the IPCC's AR5, is that we have to stop building coal-fired power stations in order to mitigate climate change," says Makoma Lekalakala, Programme Officer at Earthlife Africa Johannesburg.

The UN's landmark climate science report is likely to set a figure on the amount of fossil fuels that can be burnt if global warming is to be limited to safe levels.

Addressing biodiversity conservation in a changing climate by sharing local examples and lessons strenthened the international pool of knowledge at the 2013 International BiodiverCities Conference in Joondalup, Western Australia.

Scientists have discovered that many Antarctic ice shelves are losing ice not just by calving icebergs but by melting from their undersides as well.

Monday, 16 September is International Day for the Preservation of the Ozone Layer. A new computer-modeling study suggests that the ozone hole might have a slight warming influence, but because of its effect on winds, not temperatures.

Southern Africa could be among areas hardest hit by climate change. A rapidly expanding population is likely to add to future problems, says a new study.

The Syrian conflict that has caught the attention of the world was preceded by the "worst long-term drought and most severe set of crop failures since agricultural civilisations began in the Fertile Crescent," according to Francesco Femia, co-founder of the Center for Climate and Security.

The international Earth Hour City Challenge is giving South Africa's cities the opportunity to demonstrate their commitment to addressing climate change.

According to a new study, rising levels of carbon dioxide are harming all forms of marine life because the oceans are acidifying as they absorb the gas.

Recent research suggests that the rise and fall of the ancient world’s civilisations may have been due to a changing climate.

Last week we reached Earth Overshoot day. In a blog post for LiveScience.com, World Wildlife Fund chief scientist John Hoekstra explains just how big we're really living.

The burning of fossil fuels has caused global temperatures to spike considerably since 1950, according to a new UN report.

Following two years of failed rains, pasture is almost non-existent; where there used to be grass, there is now little more than dust.

WWF South Africa (WWF-SA), in collaboration with ICLEI-Local Governments for Sustainability - Africa, launched the Earth Hour City Challenge (EHCC) competition in SA last week.

An intense cold front is expected over the Western Cape, southern parts of the Northern Cape as well in the Eastern Cape, southern Free State and south-western KwaZulu Natal.

Heavy rain is expected in places over the southern parts of the Cape Winelands, Overberg and Eden Districts of the Western Cape, as well as the extreme south-western parts of the Eastern Cape.

According to scientists at Princeton University, as climate change gets worse, so too does interpersonal violence and social upheaval.

On 26 June 2013 CO2 in the atmosphere rocketed to 400 parts per million, partly due to emissions caused by human actions.

The melting of the Arctic icecap has become so fast and so certain that researchers can now confidently predict when the ocean will become ice-free, to within four years.
