Virtually all forms of global warming since the industrial era are caused by manmade emissions, a research says.

The world is falling short of promises made under the Paris climate deal to help the most vulnerable nations deal with the increasingly devastating impacts of climate change, according to the UN.

Greenhouse gas concentrations climbed to a new record in 2019 and rose again this year despite an expected drop in emissions due to COVID-19 lockdowns, the WMO says.

COVID-19 is expected to cause global energy emissions to fall a record eight percent this year, the International Energy Agency (IEA) says.
