The 2018 IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty [L1], idicates clearly that climate change is an existential threat. Anthropogenic emissions continue to cause further long-term changes in the climate system, such as sea level rise, increased frequency in extreme weather conditions and biodiversity and ecosystems services loss, are evident around the world. These significantly increase the risks for catastrophic events and loss of food security for the world’s growing population. According to the IPCC’s report, we have 10 years to limit climate change catastrophe and keep global warming to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.
