You may have heard of the Maldives. It’s a tropical travel paradise, with white sandy beaches and turquoise waters. An island nation in the Indian Ocean, it is composed of 26 atolls that are home to some of the world’s best diving. The Maldives is a place that’s beautiful, exotic and remote.
It’s also a place that might not be around for much longer.
This week marks the release of the new report by the Intergovernmental Panel of Climate Change, which by Friday should give a prediction of how much, and when, sea levels will rise. For the island nation of the Maldives that isn’t just a warning, it’s an expiration date.Mohamed Nasheed, the former freely elected president who was expected to be re-elected until accusations of poll fraud suspended the vote, has long been a voice for the threats of climate change to his nation (he’s the guy that held an underwater cabinet meeting), warning that if the world stands by and does nothing, the Maldives will exist no more.
Tourism is one of the Maldives’ main industries, and many of the small islands are set up as luxury resort destinations. While today you can calmly walk, dipping your toes in the calm waters, the risk that these islands will become submerged is on a not so distant horizon.
The effects of climate change are already being felt here, and in an economy that depends on tourism, storms and freak weather can have a significant impact. From erosion to coral reef degradation, the islands are changing, and in big ways.
What’s the future of the Maldives? Only time will tell, but for now, the future does not look bright.
When China set out to conduct its First National Census of Water, government officials expected to get a better understanding of the country’s rivers and other aquatic resources. But the results of that census have left some environmentalists wondering what happened to all of China’s waterways and if there is a looming water crisis for the world’s most populous nation.
Prior to conducting the water census, China estimated that it had upwards of 50,000 rivers inside of its borders. But the findings of the three-year study indicate that that number is actually 22,909. That’s a loss of more than 27,000 rivers with a combined total water volume that would be about the equivalent of the Mississippi River. That is a significant amount of water to have completely vanished.
So what exactly happened to all of those rivers? China blames their disappearance on two factors – outdated mapping techniques and global climate change. In an interview with the South China Morning Post, China’s Deputy Director of the Ministry of Water Resources, Huang He, indicated that the original estimate was probably too high due to inaccurate topographic maps that trace their origin back to the 1950s. He also acknowledged that climate change has led to the loss of both water and soil throughout China.
Environmental activists aren’t convinced, however. While many acknowledge that better mapping technology has no doubt led to a more accurate river count, there is a widely held belief that China’s booming economy and terrible record on protecting the environment both had a big impact on the loss of these waterways. This is evident in the slow, but steady, drop in water levels on the country’s two longest rivers, the Yangtze and Yellow.
Considering how quickly China’s population continues to grow and its towns and cities are modernizing, there is great fear that the nearly 23,000 rivers that do exist there will not be adequate to meet the demands placed on them in the 21st century and beyond. To make matters worse, many of those rivers are already greatly polluted, which will likely lead to a host of other health problems in the future.
China won’t be the only nation dealing with water shortages in the future if climatologists are to be believed. Climate change is drying up rivers all over the world, not to mention shifting weather patterns and causing droughts. The difference is that most other countries don’t have a population anywhere close to the size of China’s and most aren’t inflicting as much damage on their waterways as the Asian country.
Predicting what the future holds is a difficult proposition. But lets hope that when China takes its Second National Census of Water it doesn’t lose more than half of its waterways once again.
If you’re one of those people who start turning green every time your airplane hits a bit of turbulence, you’re in for a rough ride in the coming years. According to a new study, air turbulence is likely to go up by 10-40 percent by 2050, causing more passengers to reach for the airsickness bag.
The report published in the Nature Climate Change journal says that clear air turbulence – a sharp movement of air that happens even in good weather – is likely to get worse in the coming decades because of climate change.
The report’s authors studied the air over the North Atlantic, which is one of the busiest flight corridors in the world. They believe that as greenhouse gases increase, clear air turbulence will also rise – putting more planes in danger’s way. What’s more, this particular type of turbulence doesn’t show up on an airplane’s radar, making it tough for pilots to dodge. Planes that are given a heads up by other aircraft might be able to detour around the turbulence, but that would mean longer flight times and using up more fuel, which in turn contributes to the climate change problem.
But don’t start popping the motion sickness pills just yet. Some scientists say the study isn’t conclusive and believe there needs to be more research into the matter.
Climate change is a topic that many of us think is something that will affect future generations, perhaps hundreds of years from now. But what if we look at it from a different viewpoint?
What if we could travel back in time 17 million years to when the Grand Canyon was just forming? Would we have believed that the national monument, now nearly a mile deep in places, would some day be a major tourist attraction? Probably not. But time and the forces of nature that come with it, along with the effect of humans on the planet, have a way of changing what we see – sometimes dramatically.
We don’t have to go back millions of years to see such changes either. A recent study indicates that the Arctic will become drastically greener in just a matter of decades. “So what?” one might say. “Who goes there anyway?” Significant to this study on climate change is that it was done in the Arctic where not much can grow or live due to the harsh environment. To see change of any kind is unusual.
The research team included scientists from AT&T Labs-Research, Woods Hole Research Center, Colgate University, Cornell University and the University of York. These are organizations that have a very global view on things that will affect our future.
My father-in-law worked for AT&T during the early days of microwave communications and sometimes told a story of how researchers in his lab used the then-new technology to cook hot dogs. That technology would later also be used for the microwave ovens we all know so well. This story has much of the same, believable flavor.”Such widespread redistribution of Arctic vegetation would have impacts that reverberate through the global ecosystem,” said Richard Pearson of the American Museum of Natural History’s Center for Biodiversity and Conservation in an RDMag article.
It will begin with something as simple as some species of birds being unable to seasonally migrate to particular polar habitats, such as open space for ground-nesting, suggests the study. But things turn worse very quickly as the sun’s radiation, normally reflected back into space when it hits snow, will have less of it to hit and will stick around, accelerating global warming.
Just one commonly accepted effect of global warming is flooding in some coastal areas and more powerful storms.
To the world of travel, that means popular beach destinations could be under water in a few hundred years. More immediate, some of today’s iconic travel destinations, already struggling with sea level issues like Venice, Italy, or the Netherlands, could be doomed much quicker.
Right now, for example, Venice, Italy, is being protected against rising tides in the Adriatic Sea by rows of mobile gates, intended to isolate the Venetian Lagoon when the tide rises above a certain level. The Netherlands, a geographically low-lying country, has a great amount of its land and people at or below sea level and will also be affected by rising ocean levels.
This new study, while not talked about much in the press, is a clear indicator of what the future holds and good food for thought.
Of even more immediate concern, and visually a clear indicator of a problem we can do something about, is today’s reality of the “floating island of plastic” in the Pacific Ocean.
Brought to the area by ocean currents that move around the planet like a slow-motion whirlpool, opposing the wind and earth’s rotational forces, tens of thousands of pounds of garbage wash ashore here every year.
“These ecosystems are very connected. If the oceans are in trouble, we humans are in trouble. We don’t realize that we are threatening our own existence,” says Dr. Gregor Hodgson, founder and executive director of Reef Check Organization in this video.
For years we’ve heard environmental scientists and researchers tell us how climate change is having a profound effect on glaciers across the globe. In many parts of the planet, increased temperatures have caused the giant sheets of ice to dramatically recede or disappear altogether. That process has now begun to take place in one of America’s most iconic landscapes – Yosemite National Park.
Last week, the National Park Service announced that Lyell Glacier, the largest inside the park, has stopped advancing and is losing substantial mass. The NPS, working in conjunction with the University of Colorado, conducted a four-year study of the glacier, measuring its movement by placing stakes along the ice and recording their positions. Over that four-year period, those stakes didn’t move at all. The study also conducted research on the nearby Maclure Glacier, which runs adjacent to Lyell. The findings indicate that it is still advancing at a rate of about one inch per day, despite the fact that it has lost nearly 60% of its mass as well.
Glaciers build up over thousands of years due to the accumulation of ice and snow in mountainous areas. When they grow large enough their mass, combined with melt water, causes them to slide down hill at a generally very slow, but powerful, pace. When they stop moving altogether or start to retreat, it is because they no longer have the mass or moisture to push them downhill. This has increasingly been the case with some of the largest glaciers across the planet.
Research will continue over the next few years as scientists will record a host of climate data in and around both the Lyell and Maclure Glaciers. They’ll monitor the thickness of the snowpack, range in temperatures and rate of ice melt in an effort to further understand the effects of climate change on the two bodies of ice. It seems clear, however, that warming temperatures have already begun to have an effect.
