Coastal cities face challenging times in a climate-changed world

What Does the Future Hold for America’s Coastal Cities?

Scientists have observed a rapidly-growing atmospheric carbon presence. Whatever your views on the cause of this phenomenon, the trend is confirmed and supported throughout the scientific community. And with increasing levels of atmospheric carbon, and the subsequent UV heat-trapping, global temperatures continue to rise. With warming atmospheric temperatures, ocean levels will also gradually increase, heralding a plethora of future problems…

The beauty of the ocean hides within it troubling secrets, such as a decrease in oxygen levels that could lead to increasing "dead zones"

Ocean Oxygen : Suffocating the Seas

Ocean breathing – From the shallows down to its yawning depths, the ocean gets its oxygen from the surface, supplied either by the atmosphere or from the release of oxygen in phytoplankton through photosynthesis. Scientists have long known that one expected consequence from a warming climate is a gradual drop in the amount of oxygen dissolved into ocean waters as they absorb…

Coral bleaching off the coast of Thailand

Climate Change, El Niño Prolong Coral Die-off

The news earlier this month of a record low Arctic sea ice in January, combined with the hottest January on record and four separate studies corroborating accelerating sea level rise is only some of the recent news pointing to a rapidly changing global climate. In a press statement released today by the American Geophysical Union, scientists from the National Oceanic and Atmospheric Administration report…

A coral reef turned white by bleaching, a stress reaction to high ocean temperatures

Imperiled Coral Reefs, Gone by 2050?

  Even now, three-quarters of all coral reefs around the world are threatened. By 2050 “nearly all” coral reefs will be gone unless something is done soon to stop it, according to a report released last week by the World Resources Institute. Assaulted by warming temperatures, acidifying waters, pollution, and overfishing, coral reefs are aptly described as the “rainforest of…

Global Coral Bleaching Among Worst Ever Seen

Coral reefs are a foundation for a healthy ocean ecosystem, serving as home for a wide variety of plants and animals. Coral communities play a vital role across the entire food chain, from the tiniest creature right up to humans. The National Oceanic and Atmospheric Administration (NOAA) estimates that healthy coral reefs generate up to $375 billion annually in food,…

Bleached coral across the globe: a harbinger of climate change

Sea Surface Surface Temperatures Lead to Coral Bleaching Across the Globe

A global coral bleaching event is underway that many scientists fear will surpass 1998, the last global coral die-off that bleached and killed 16 percent of the world’s coral. Already, rising sea surface temperatures have devastated coral off the coast of Indonesia after ocean temperatures in the coastal waters spiked to 93 degrees Fahrenheit earlier this year. The record heat…

Warming Oceans Lead to Massive Coral Die-off in Indonesian Waters

Water temperatures reaching as high as 93 degrees Fahrenheit in Southeast Asia’s Andamann Sea have led to a large die-off of coral reef off the coast of Indonesia, the Wildlife Conservation Society (WCS) reported earlier this week. The abnormally high ocean temperatures lasted for about a month, the report said. Surveys conducted in May, when temperatures started to peak, revealed…
