Bleaching Poses Threat to Hawaii’s Coral Reef

Coral reefs, already under threat around the globe, may be in particularly acute danger in the waters of Hawaii because of a phenomenon known as bleaching.
Coral makes up less than 1 percent of the underwater ecosystem yet helps to protect 25 percent of marine species, generates tourism revenue and boosts fishing.
Many scientists say coral bleaching, which causes a change in colour and can result in the eventual death of algae, is but one of the effects of warmer ocean temperatures.
The warning came from a report, which finds that a global coral bleaching event that began last year in the Pacific Ocean may be spreading to the western Atlantic Ocean—and to Hawaii.
The potential result could be widespread death of corals and an effect on the "long-term supply" of fish and shellfish.

Earth's Hottest Year on Record was 2014

According to a report from scientists, the unusually warm weather felt last year across most parts of the world, made 2014 the hottest year in recorded history.
Several markers of climate change such as rising land and ocean temperature, sea levels and greenhouse gases set new records in 2014, the fifth warmest year since national records began in 1901.

Largest Bird-like Dinosaur Unearthed

A team of palaeontologists working in China has unearthed the fossil remains of the winged dinosaur - a close cousin of the Velociraptor.
Named Zhenyuanlong suni, the feathered dinosaur is the largest ever discovered to have a well-preserved set of bird-like wings.
Its wings are very short compared with other dinosaurs in the same family.

Acidic Arctic Ocean

One byproduct of rising carbon-dioxide levels is increasing ocean acidity, a phenomenon that scientists have termed an existential threat to marine life. The waters of the Arctic and the far-north Pacific are particularly prone to acidification as a result of several natural factors, so scientists regard the region as the proverbial canary in the coal mine for the rest of the world's oceans. A new study shows that within just fifteen years these waters may be too acidic for a range of marine animals to build and maintain their shells year round.

Air pollution Kills 9,500 in London Every Year

Each year nearly 9,500 people die in London due to long-term exposure to air pollution, more than twice as many as previously thought. The premature deaths are due to two key pollutants, fine particulates known as PM2.5s and the toxic gas nitrogen dioxide (NO2).
The study is believed to be the first by any city in the world to attempt to quantify how many people are being harmed by NO2. The gas is largely created by diesel cars, trucks and buses, and affects lung capacity and growth.
Previous research had attributed 4, 267 annual premature deaths in London due to air pollution in 2008.
