Scientific evidence for human-caused climate change is undeniable, according to the Intergovernmental Panel on Climate Change (IPCC). Greenhouse gas emissions, which are driving climate change, are reported by the United Nations to have reached new highs in 2017 at 146% of pre-industrial levels. An analysis by the World Meteorological Organization shows that the five-year average global temperature from 2013 to 2017 was the highest on record.
With rising greenhouse gas emissions, climate change is making its effects (droughts, floods, heat waves, extreme weather events and sea-level rise) felt worldwide at rates much faster than anticipated. While the UN confirms positive steps are being taken, far more ambitious plans and accelerated action are urgently needed on climate mitigation and adaptation.
