Global warming is killing the Carteret Islands as tides sweep away a people’s community and culture.
The last time I wrote about global warming,the collapse of ice sheets and rising sea level several readers contacted me with views ranging from “Stop scaring my children” to “Don’t you know climate change is a hoax”. We all have our opinions but today there is overwhelming evidence that the world is getting warmer.
Chief among the “believers” are the Carteret Islanders. Some 2000 people lived there and over the last 25 years sea level has risen more than 10 cm. Now this doesn’t sound much but it takes away a lot of that tiny 0.6 square kilometers that they all share. Worse is …

I began my research on the Great Barrier Reef way back in the 70’s.
There didn’t seem to be many fishermen around then and everywhere I looked the coral and marine life was flourishing. It was incredible!
Yesterday I read a research report by Dr. Matthew Spencer and Jennifer Cooper from the prestigious NIMBioS Institute. They were looking at the impact of global warming on the Great Barrier Reef and trying to predict where the impact of climate change was taking us.
Most readers know that the Great Barrier Reef is the largest reef system on the planet; in fact it is often described as the largest structure created by living things (the coral colonies). It’s been around a long …

The UK Energy Research Centre claimed (2009) that oil production was likely to peak before 2030 and possibly as early as 2020. We are facing a time when oil becomes increasingly expensive as resources dry up. Scientists in Kuwait predicted in 2010 (the latest prediction) that world conventional crude oil production will peak in 2014; this year and almost a decade earlier than some other predictions. Their study is in ACS’ Energy & Fuels.
More than 40,000 oil fields are scattered around the globe, on land and offshore. The largest are the Burgan Field in Kuwait and the Ghawar Field in Saudi Arabia. Each has more than 60 billion barrels yet to be harvested. That sounds like a lot but …

Just over a month ago I was sitting somewhat bewildered at my desk and rereading two research papers about the antarctic ice collapsing. I had known about sea level rise for many years now but this was big news; the enormous West Antarctic ice shelf was melting and breaking up on a slow slide into the ocean.
As it turns out glaciologist Terence Hughes had foreseen the disaster when he published “Is the West Antarctic Ice Sheet Disintegrating?” back in 1973 (Journal of Geophysical Research). Hughes, now retired, was ‘old school’ and worked on the ice. Because access to this frozen continent is so difficult it has been nearly impossible to collect enough data to test his prediction.
It was …

I’ve spent the last 40 years in the waters of the Great Barrier Reef and shark attacks were always a big concern. During the ‘early days’ I saw so many sharks that I included them in my census work just because they were all around me. In many places, sharks of all species averaged about 15 individuals per hectare of reef slope.
I was always concerned about them following behind me as I was towed along the reef edge. I saw myself as an overgrown fishing lure and Australia’s reputation as the shark capital of the world didn’t settle my nerves during those long hours underwater.
So how real is the case against sharks?
According to the Australian Shark Attack …

Another year had passed and concerned people were celebrating World Ocean Day on June 8th. We all depend on a healthy and clean ocean for our very survival and the latest scientific research is painting a dismal picture of things to come. Most of us know we need to act to turn around the damage caused by unwise use, pollution, and over fishing. But few of us do anything.
This year’s World Ocean Day theme is, “Together we have the power to protect the ocean” and all over the globe small groups of people set out to make a difference.
Perhaps the smallest but most well meaning effort was on the tiny island of Langkawi just a few kilometers from …

In my last post I was talking about one of the world’s most destructive fishing methods; bottom trawling for shrimp. This is the way most wild shrimp are caught and it has created an environmental disaster in terms of destruction of the seabed and what lives there. Bottom trawling has to end if we are to have sustainable fisheries in the future.But what about shrimp farming?
Because catching shrimp has become more difficult, the world has quickly turned to shrimp farming as a way of meeting the accelerating demand. Today, about 90% of American shrimp is imported from Bangladesh, China, Thailand, and Vietnam where shrimp farming has become an art and environmental protection is almost non-existent.
Commercial marine shrimp farming …

I grew up in Miami and the Florida Keys where shrimp fishing was ‘king’. I can still remember the excitement of running down the dock to buy a bucket of shrimp when the shrimp fishing boats returned (shrimp only came in buckets). My Mom seemed to have a hundred ways to cook shrimp and I loved all of them.
I wasn’t alone. Forrest Gump’s friend “Bubba” had spent hours relating the uses of shrimp during the critically acclaimed 1994 movie starring Tom Hanks.
Shrimp is highly valued and fished for in all the places I have lived. It’s a very popular food. In fact the world catch is about 3.4 million tonnes and much of this from Asia.
But shrimp …

It’s just on a month ago that staff at The Andaman Resort were preparing for the arrival of their biggest ever CSR group to join our coral reef rescue. Community and Social Responsibility (CSR) has become the latest team activity of concerned businesses around the world who realize that they do owe something to the environment and community that has contributed in part to their success.
The group was the CEO Circle from the huge Thomson Reuters Corporation and the participants were all about getting things done and moving ahead. What was wonderful is that they had chosen the location for its incredible natural setting and geological history and, perhaps most significantly, the coral reef rescue program. They wanted to …

The Guardian reported (4TH April, 2014) that Japan’s biggest online retailer, Rakuten, will stop their whale meat and dolphin meat sales by the end of April after the International Court of Justice ordered Japan to immediately halt its annual whale hunts in the southern ocean.
Rakuten said it had asked sellers to cancel sales of whale meat products on its website “in accordance” with the ICJ ruling. Monday’s verdict in the Hague. It should be pointed out that it did not cover whale meat sales within Japan, which are legal, or the country’s slaughter of whales in the north-west Pacific and in its own coastal waters.
The decision by Rakuten comes soon after the UK-based Environmental Investigation Agency (EIA) exposed …

In May, 2013 the United Nations published its first plan for deep sea mining saying companies could apply for mining licenses as soon as 2016. To date the UN’s International Seabed Authority has issued 17 exploration permits with 7 more pending.
“We are at the threshold of a new era of deep sea mining” said Michael Lodge, legal counsel for the ISA. An assessment of the Pacific Ocean has estimated more than 27 billion tonnes of rocks could be lying on its floor, including 290 million tonnes of copper and 340 million tonnes of nickel.
The extraction of the rock ‘nodules’ – small mineral-rich rocks from the seabed, has been around as a concept for decades but deep sea mining …

Ten years ago on December 26 the third largest earthquake in recorded history created a lethal tsunami that tore through Asia leaving behind an estimated 280,000 dead. It also reached far into the future by destroying coral reefs that are the ‘bread-basket’ of nearly 200 million people in this part of the world. Now artificial reef construction is turning the tide.
My first blog with Epoch Times was August 3rd last year when I reported on the exciting work being done at Langkawi’s Andaman Resort. Titled “We’re Building a Reef for Our Children” the Epoch Times blog tracked the progress of the resort’s investigation into coral reef damage and their environmentally responsible response.
First, they initiated a “coral clearing” program …

I saw my first Leatherback turtle in the Florida Keys long before that string of gorgeous islands became the foundation of endless high-rise buildings. It reminded me of a flattened car; it was huge!
Leatherback turtles can grow to over 3 m long and weigh nearly 1,000 kg. Its front flippers can reach an amazing 2.7 m. They dive to depths of more than 1,000 m and can make trans-Pacific migrations from Indonesia to the U.S. Pacific coast and back again. Surprisingly, they are no larger than other sea turtles at hatching weighing in at only 46 g.
More amazing is that these ancient giants that evolved about 110 million years ago feed almost exclusively on jellyfish. They follow their …

In my last report about climate change I was looking at the plight of polar bears as their frozen habitat shrinks into oblivion. It’s all very sad but it is after all half a world away. I’m still OK, right?
Actually it’s bad news for all of us. I live only a few hundred kilometres from the equator and will be among the hardest hit by this change to the Arctic Ice.
Scientists say that the pattern of ocean circulation was radically altered in the past when climates were warmer. Ancient warm periods offer insights into future warming. The mid-Pliocene, 3 million years ago, was a period of global warmth that is often considered as an analogue for …

As the Arctic sea ice disappears due to global warming, so too will Polar Bears and the climate we know today.
Sea ice scientists working in the Arctic say it’s not a question of “if” there will be nearly ice-free summers, but “when.” The news is that “when” is sooner than we thought — before 2050 and possibly within the next decade or two. Using three different modelling techniques they came up with an ice free Arctic by 2020, 2030, or 2050.
James Overland and Muyin Wang, both of NOAA, published their extraordinary results in Geophysical Research Letters April 12, 2013.
In another study from the Bjerknes Centre (January14, 2013) it was confirmed that Arctic sea ice is shrinking in …

I’ve spent most of my life working close to sharks. They were always a concern and I certainly have had a few moments when I doubted the sense in what I was doing. But now I’m concerned about what’s happening to sharks on a global scale. I’m concerned about tipping points and the shark fin soup industry.
Why am I so upset? It was never fun swimming around in very deep water with Oceanic Whitetip sharks. Jacques Cousteau described them as “the most dangerous of all sharks”. Since those days there are very few left of what was once the most common large predator on earth. Cousteau’s “most dangerous of all sharks” are becoming the ‘most endangered of all sharks’.…

I was recently bemoaning the sorry state of the Oceanic Whitetip Sharks and mentioned that there was just a Conference of the Parties (CITES) meeting in Bangkok about 6 months ago to look at shark protection. What was only a few years ago the most abundant large predator on Earth is now little more than a memory.
I also made mention of the fine work of Dr. Shelley Clarke who estimated from market surveys that between 26 million and as many as 73 million sharks were harvested each year worldwide. Her best estimate was 38 million sharks killed annually.
We may have had that wrong. On March 1, 2013, “Global Catches, Exploitation Rates and Rebuilding Options for Sharks,” was published …

I always associate the phrase “rising mercury” with ‘skyrocketing’ temperatures. I grew up in the tropics in an age before digital thermometers. An increase in the height of that silvery column meant more unpleasantness ahead.
But now scientists at Dartmouth University publishing in the journal Plos One have found that rising ocean water temperatures bring about an increase in the amount of mercury in fish.
So how does this happen?
Mercury is released into the air through industrial pollution. It falls with the rain in the many forms including methylmercury and is extremely toxic. Mercury isn’t the kind of material we want in our bodies; it hangs around for a long time and causes a variety of problems including damage …

I was being towed behind a small boat 150 km from shore and counting reef fish as part of my underwater surveys on the Great Barrier Reef. On one side of me the water was about 10 metres deep, bright and colorful with coral and fish and then it plunged down to nearly 1000 metres of icy darkness just beneath me.
I’d had company since I first dived into the inky water. Just on the edge of my visibility a pair of Oceanic Whitetip Sharks, Carcharhinus longimanus, had followed my every move.
All I could see of them was the silvery tips of their huge pectoral fins. Growing to four metres and 170 kg and considered responsible for most open …

Not many people know what ‘ghost fishing’ is. It sounds scary and in fact is; but not for the reasons you might think.
Ghost fishing is when lost or discarded fishing equipment just keeps on catching fish. The caught fish die and attract more marine life to their death. This endless circle of destruction can go on for decades.
In a recent report by Emily Rose Nelson of the R J Dunlop Marine Conservation Program she stated that something like 640,000 tons of fishing gear is lost or discarded at sea every year.
I did most of my marine research in northern Australia and we had teams working in the Gulf of Carpentaria; one of the country’s most productive fishing …
