Whilst COVID-19 has caused severe international health and economic crises, failure to tackle climate change may threaten human well-being, ecosystems and economies for centuries,” said World Meteorological Organization (WMO) Secretary-General Petteri Taalas on the 50th anniversary of Earth Day celebrated on 20 April. “We need to flatten both the pandemic and climate change curves,” he added. Previous economic crises have often been followed by “recovery” associated with much higher emission growth than before the crisis. Thus the agency has proposed that post COVID-19 stimulus packages should help the economy grow back 'greener'. "These six principles constitute an important guide to recovering better together. Greenhouse gases, just like viruses, do not respect national boundaries. On this Earth Day, please join me in demanding a healthy and resilient future for people and planet alike," said Gutteres.
COVID-19 may result in a temporary reduction in greenhouse gas emissions, but it is not a substitute for sustained climate action. And it will make it more difficult to tackle weather, climate, and water-related hazards which are becoming more acute because of climate change.
UN Secretary-General António Guterres has also proposed six climate-related actions to shape the recovery and the work ahead.
