There has been much news recently about the growing bleaching events going on in the world’s coral reefs associated with ocean warming and acidification. The massive damage to Australia’s Great Barrier Reef is an ongoing tragedy.
According to a new paper published in the journal Nature, global warming has damaged huge sections of Australia’s Great Barrier Reef. The authors of the paper warn that the resilience of the reef – which is the world’s largest living structure – is waning rapidly.
Climate change is posing a major threat to the future of coral reefs. According to a recent United Nations-backed study, if swift action is not taken to curb greenhouse gas emissions, annual coral bleaching events will affect nearly all of the world’s coral reefs. And coral bleaching can result in serious coral mortality – as Australia’s Great Barrier Reef has recently illustrated.
Jellyfish are fascinating in appearance but generally are nothing but trouble. Their stings can ruin a tropical vacation but they can cause far more damage than that.
We’ve all come to take for granted the ability of GPS systems to help us find our way around our cities, the countryside and, for that matter, the world in general. Software interacting with Global Positioning Satellites allows us to pinpoint our location on the Earth with remarkable accuracy. At least, as long as places on Earth stay put. But the problem is that they actually don’t.
Wilderness areas are strongholds for biodiversity. They buffer and regulate local climates, and they support many of the world’s most politically and economically marginalized communities. While there is a great deal of attention being paid to the loss of species around the world, there is relatively little focus on the loss of entire ecosystems. Simply put, wilderness is on the decline, and it has been ever since human civilization began its inexorable expansion.
The majestic great white shark has been around for a very long time. Its evolutionary origin dates back 14 to 16 million years. And while great whites still enjoy decent populations off the coasts of Canada, Australia, and the United States, the same can’t be said for South Africa’s great whites.
It was already well-known that coral bleaching was a serious problem in the Great Barrier Reef, but extensive aerial surveys and underwater dives have now revealed the shocking extent of the problem.
Ecotourism is increasing on a global scale. Ecotourism is generally defined as responsible travel to natural areas that conserves the environment, sustains the well-being of the local people, and involves interpretation and education. Visitor numbers to many protected areas around the world are expanding every year. Ecotourism provides rich experiences for the traveler and often has great benefits to local communities fighting poverty and seeking sustainable development.
Water is a simple chemical compound containing two hydrogen atoms and one oxygen atom connected by covalent bonds. It covers 71% of Earth’s surface and is vital for all forms of life. Despite its abundance, water that is safe for drinking is globally in short supply.
Crocodiles are large aquatic reptiles that live throughout the tropics in Asia, Africa, the Americas, and Australia. The first crocodiles appeared approximately 240 million years ago – around the same time as dinosaurs. And while the resilient species did survive the last great extinction, crocodiles might not be climate change-proof after all.
An international poll of over 45,000 people in 40 countries looked at opinions about climate change and the need to curb greenhouse gas emissions. The results are quite interesting.
