Chile, which is leading the last round of climate negotiations, has only joined a number of countries by publishing more ambitious climate action plans for years to come.

Megan Darby reported at a press conference where a trio of Chilean ministers wore masks against the corona virus and promised the nation would peak greenhouse gas emissions by 2025, two years earlier than stated in the draft proposal.

Chile has been one of many campaigns for all governments to submit a stronger plan this year to the United Nations at the first five-year milestone of the 2015 Paris Agreement, although it is appropriate official requirements murky.

So far, only a few are obedient and the coronavirus pandemic has become complicated the plans of many countries to increase ambition.

Before Chile, only the Marshall Islands, Suriname, Norway, Moldova, Japan and Singapore submitted a renewed 2030 action plan, according to one World Resources Institute tracker. Dominated by Japanese, who face criticism because most repeat promises from 2015 – they represent 2.8% of global emissions.

The postponement of this year’s climate summit, which was originally scheduled to be held in Glasgow in November, until 2021 did not affect Paris’s request that all countries submit plans “In 2020” – or December 31.

Flight and emissions

Chloé Farand write about how airlines seek help from new carbon emission regulations that will start in 2020 after the coronavirus pandemic caused the fall of international flights.

The International Air Transport Association (Iata), which represents the world’s airlines, wants to change the baseline from which CO2 emissions from traffic growth will be assessed in the coming years to reduce the likelihood of an increase in the 2020s, when traffic recovers from current depressed levels this.

The move, he said, would “avoid an undue economic burden on the sector”.


The flight landing gives scientists a rare opportunity to study the clear sky and find out how contrails – white lines of steam left behind from jets – for high altitude clouds that trigger global warming. The formation of clouds caused by air travel is one of the least understood fields of climate science.

The last time the sky was as clear, at least above the United States, was after the 9/11 suicide hijackers’ attacks in 2001. Airplane footprints could contribute at least to climate change – by trapping heat – as well as carbon dioxide from the fuel they burn.

Count penguins

People who have been forced to stay at home because coronaviruses contribute to citizen science in record numbers – from counting penguins to mapping solar panels.

Read Megan Darby attractive and pleasing appearance in this lockdown project. Zooniverse, which assigns volunteers to work on subject matter from literature to space exploration, noting five million “classifications”, or images processed, last week – four times the usual amount.

By the way, this Climate Weekly came to you a day early because of the long Easter vacation in Europe: maybe there is an opportunity to try some citizen science?
