The global average of carbon dioxide concentrations hit a new high of 413.2 parts per million last year, according to the WMO report. It was higher than the annual average over the last decade, despite a 5.6% drop of CO2 due to Covid.
Leaded gasoline is no longer used anywhere in the world, according to the United Nations Environmental Program (UNEP). Algeria, the last country left using leaded gasoline, finished its stockpile in July.
High levels of smart device screen time, such as looking at a mobile phone, is associated with around a 30% higher risk of myopia and, when combined with excessive computer use, that risk rose to around 80%.
The most powerful previously detected quakes occurred in the Cerberus Fossae region on Mars, where lava may have flowed in the geologically recent past.
Scientists have long noticed an absence of ammonia in the atmospheres of Uranus and Neptune. Scientists now think that ammonia in the upper atmosphere formed “mushballs” by merging with water.
IBM Space Tech is launching Endurance, CubeSat mission that children from all over the world will be able to use to gain access to space.
The first research paper from Perseverance rover team was published lately. It shows that Jezero Crater on Mars was probably the site of some violent floods.
A colossal US$22-billion infrastructure project will send Australian sunshine more than 5,000 km to Singapore, via high-voltage undersea cables.
The average temperature at the Amundsen–Scott South Pole Station between April and September, a frigid minus - 61 Celsius and was the coldest on record, dating back to 1957.

Researchers are developing artificial intelligence that could assess climate change tipping points. The deep learning algorithm could act as an early warning system against runaway climate change.
New research has just answered one of the fundamental questions about our universe: Why did some of the oldest, most massive galaxies go quiescent early in their formation? The answer, we now know, is because they ran out of cold gas.
About a year ago, the XENON1T experiment reported an unexpected signal, or excess, over the expected background. This signal could be attributable to dark energy.
Other rovers have also experience dust devils, but Jezero crater, Perseverance’s landing site, seems to have a high occurrence of dust devils.
