Australian Senate Passes Law for 43% Greenhouse Gas Reduction

Australia's Senate voted to ensure the government's elevated target of reducing greenhouse gas emissions by 43% below 2005 levels by the end of the decade is enshrined in law.
The Senate passed legislation supporting the target in a vote of 37 to 30 even though several senators who supported it wanted a more ambitious 2030 target.
Climate Change and Energy Minister Chris Bowen said that the Senate vote provided certainty to clean energy investors while strengthening transparency and accountability in Australia's carbon reduction processes.

Just a Small Rise in Earth's Temperature Could Cause Irreversible Ecosystem and Weather Changes

From melting ice sheets to stressed coral reefs, global warming is changing our world in unmistakable ways. But identifying "tipping points," thresholds past which such transformations become irreversible or self-sustaining was more difficult—and controversial. Some researchers argue that emphasizing looming but uncertain points of no return could feed public apathy, rather than energize efforts to curb climate change.

Enigmatic Reef-Like Structure Discovered in Australia

An analysis of advanced satellite images from the German Aerospace Centre revealed an ancient landform with a circular rim and central dome 'hidden' in plain view on the Nullarbor Plain in Australia.
The Nullarbor Plain is a 200,000 km2 karst surface in southern Australia, underlain by ancient shallow-water limestones.
The plain, which emerged from the ocean about 14 million years ago, is relatively flat with a general relief of less than 10 m.
It is bounded to the north by the Great Victoria Desert, while abruptly terminating to the south, with up to 90 m high cliffs facing the Southern Ocean.
"Unlike many parts of the world, large areas of the Nullarbor Plain have remained largely unchanged by weathering and erosion processes over millions of years, making it a unique geological canvas recording ancient history in remarkable ways.

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.
