Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Nasa has released a series of satellite pictures which capture the impact of extreme weather events around the world in 2020.

The new pictures, part of a wider project called ‘Images of Change’, were released by Nasa's Global Climate Change group and are mostly composed of before-and-after shots which demonstrate the damage left in the wake of climate related events such as severe floods and wildfires.

Also included are pictures showing more prolonged measures of climate change, such as receding glaciers and desertification.

One pair of pictures shows the Mekong River, an important lifeline to nearly 60 million people across southeast Asia, changing colour.  

While the water normally appears brown due to floating sediments, a section of the river in Thailand turned a bright blue in 2020.  

Scientists said the change was due to shallow, slower moving waters not carrying as much sediment after a lengthy drought.

Nasa also captured pictures of Antarctica's second largest ice shelf showing record amounts of meltwater. 

Scientists were concerned by the level of water, which was the highest in nearly 50 years of observation.

Particularly striking are pictures of flooding, such as in last year’s monsoon season in Bangladesh, where large areas of land are shown dry (before) then submerged (after).

Nasa said the 2020 monsoon season was unusually severe and a report from the UN Office for the Coordination of Humanitarian Affairs found more than 500 people were killed and more than 167,000 families were displaced across Bangladesh.

Not all of the pictures show climate change disasters. There is one pair showing India's Lonar Lake changing colour from green to pink, an as yet unexplained phenomenon.

There are also plenty of pictures of volcanic eruptions. On the Philippine island of Luzon, the Taal volcano erupted on 12 January 2020 depositing wet, heavy ash over the lush green landscape.

As the ash dried, it hardened from a mud-like consistency to that of cement, damaging most of the island's crops and other vegetation.

Hundreds more before and after pictures from Nasa’s Images of Change project can be viewed on the agencies climate change website.
