‘United in Science’ is a recent report compiled by the World Meteorological Organization on behalf of the United Nations Secretary-General Antonio Guterres. It attempts to bring together the latest climate science-related updates from a group of key global partner organisations. Here, Guterres rings the UN Peace Bell on World Peace Day.

For instance, sea-level rise has accelerated, threatening lives and livelihoods, according to the report. It will continue for centuries. Here, melting sea ice in the Arctic is seen.

However, carbon dioxide emissions have largely bounced back to pre-pandemic levels, according to ‘United in Science’. Here, a blue sky is seen above Humayun’s tomb in Delhi in March 2020.

Here, smoke rises above a district in Mizoram after a massive forest fire earlier this year.
