WMO Statement on the State of the Global Climate in 2019 (World Meteorological Organization, March 2020, 40p)

An annual survey of global climate indicators (temperature, greenhouse gases, and ozone, oceans, cryosphere, high-impact events) and climate-related risks to human health, food security, population displacement, marine life, and biodiversity). The past five years are the five warmest on record, and greenhouse gases have reached record levels. As the ocean warms it expands and sea levels rise, further increased by the melting of ice on land, especially in Greenland and Antarctica. UN Secretary-General Guterres, in his Foreword, warns that “We are currently way off track to meeting either the 1.5°C or 2°C targets that the Paris Agreement calls for. We need to reduce greenhouse gas emissions by 45% from 2010 levels by 2030 and reach net zero emissions by 2050… Even if we are successful in limiting warming to 1.5°C, we will face significantly increased risks to natural and human systems.” To insure a safer and sustainable future for all, “we need more ambition on mitigation, adaptation, and finance.”
