Air Pollution in China Back to Pre-Covid Levels

Air pollution in China has climbed back to pre-pandemic levels, and scientists say Europe may follow suit.
Air pollution causes at least 8m early deaths a year, and cleaner skies were seen as one of the few silver linings of Covid-19. Experts have called for action to help retain the air quality benefits of lockdowns, and measures taken to date have included expanding cycle lanes and space for walking in cities.
Data from the Centre for Research on Energy and Clean Air (Crea) shows concentrations of fine particles (PM2.5) and nitrogen dioxide (NO2) across China are now at the same levels as one year earlier. At the height of the country's coronavirus response in early March, NO2 levels were down by 38% from 2019 and levels of PM2.5 were down by 34%.

Millipede From Scotland is World's Oldest-Known Land Animal

A fossilized millipede-like creature discovered in Scotland may represent the oldest-known land animal, a humble pioneer of terrestrial living 425 million years ago that helped pave the way for the throngs that would eventually inhabit Earth's dry parts.
Researchers said the fossil of the Silurian Period creature, called Kampecaris obanensis and unearthed on the island of Kerrera in the Scottish Inner Hebrides, inhabited a lakeside environment and likely ate decomposing plants.
Fossils of the oldest-known plant with a stem, called Cooksonia, were found in the same ancient lake region as Kampecaris.

Australia's Megafauna Roamed the Tropics with First Humans But Then Disappeared

Giant wombats, six-metre-long goannas and the world's largest kangaroos are among the enormous megafauna that inhabited Queensland between 40,000 and 60,000 years ago.
Some scientists have argued that hunting by humans was a possible cause of their extinction, but new evidence suggests it was most likely major climatic and environmental change.
