Zimbabwe Moves 2,500 Wild Animals because of Climate Change

Zimbabwe began moving more than 2,500 wild animals from a southern reserve to one in the country's north to rescue them from drought, as the ravages of climate change replace poaching as the biggest threat to wildlife.
About 400 elephants, 2,000 impalas, 70 giraffes, 50 buffaloes, 50 wildebeest, 50 zebras, 50 elands, 10 lions and a pack of 10 wild dogs are among the animals being moved from Zimbabwe's Save Valley Conservancy to three conservancies in the north — Sapi, Matusadonha and Chizarira — in one of southern Africa's biggest live animal capture and translocation exercises.
Project Rewild Zambezi," as the operation is called, is moving the animals to an area in the Zambezi River valley to rebuild the wildlife populations there.

New Species of Pearl Oyster Discovered

Marine biologists described a new species of the oyster genus Pinctada from the east coast of Phuket Island, Thailand, in the Andaman Sea.
Pinctada is a genus of saltwater oysters in the bivalve mollusk family Pteriidae.
There are approximately 20 scientifically recognized Pinctada species.
They are widely distributed from shallow to deep waters of the tropical and subtropical regions between the Indo-Pacific and western Atlantic.
They are not closely related to either the edible oysters or the freshwater pearl mussels.
Several Pinctada species produce the pearls of jewellery quality that seem to have sustained from ancient times the human definition of beauty and rarity.

Over 99% Population Breathes Air Exceeding WHO's PM2.5 Guidelines

According to a report by Greenpeace India, over 99 per cent of India's population is breathing air that exceeds the World Health Organisation's health-based guidelines with respect to PM2.5.
As per the key findings in the report titled "Different Air Under One Sky", the greatest proportion of people living in India are exposed to PM2.5 concentrations more than five times the WHO annual average guideline.
As per the report's annual average PM2.5 exposure analysis, the region with the highest exposure to pollution in the country is Delhi-NCR.

Africa's Oldest Dinosaur Discovered in Northern Zimbabwe

A team of palaeontologists discovered a new early skeleton that is so far, the oldest dinosaur skeleton ever found in Africa. It is estimated Mbiresaurus raathi was a long-necked dinosaur that was about 6 feet long, weighing between 10 and 30 kilograms. A graduate student at Virginia Tech discovered the mostly intact fossil in Northern Zimbabwe and it was unearthed over two digs in 2017 and 2019.
The discovery of Mbiresaurus raathi fills in a critical geographic gap in the fossil record of the oldest dinosaurs and shows the power of hypothesis-driven fieldwork for testing predictions about the ancient past.

Greenland's Zombie Ice Will Raise Global Sea Level by 10 Inches

As per repots, Zombie ice from the massive Greenland ice sheet will eventually raise global sea level by at least 10 inches (27 centimeters) on its own.
Zombie or doomed ice is ice that is still attached to thicker areas of ice, but is no longer getting fed by those larger glaciers. That's because the parent glaciers are getting less replenishing snow. Meanwhile the doomed ice is melting from climate change.
The unavoidable ten inches in the study is more than twice as much sea level rise as scientists had previously expected from the melting of Greenland's ice sheet.

G20 Environment Ministers in Bali Spur Global Climate Action

Environment officials from the Group of 20 leading rich and developing nations met on Indonesia's resort island of Bali for talks on climate action and the global impact of the war in Ukraine, with Indonesia's Environment Minister saying the world is already facing a climate crisis.
They discussed the implementation of each G20 nation's contribution to fighting climate change and synchronising targets among developing and developed countries.
Indonesia, the holder of this year's G20 presidency, is committed to reducing its greenhouse gas emissions by 41% with international assistance by 2030, or by 29% independently.

Hornsea 2: North Sea Wind farm Claims Title of World's Largest

The world's largest offshore wind farm is now fully operational, 55 miles off the coast of Yorkshire.
The Hornsea 2 project can generate enough electricity to power about 1.3 million homes - that's enough for a city the size of Manchester.
A decade ago renewables made up just 11% of the UK's energy mix. By 2021 it was 40%, with offshore wind the largest component.
Hornsea 2 is part of a huge wind farm development by energy firm Orsted.
"The UK is one of the world leaders in offshore wind.
Hornsea 2 has taken the title of "world's largest" from its neighbour Hornsea 1. It covers an area about four and half time the size of Liverpool.
