Rate Of Climate Change Questioned By Scientists
|MessageToEagle.com – Most ordinary people and scientists agree that our planet is experiencing serious climate changes. What is uncertain is how fast these changes are happening. A new study now questions the rate of the climate changes.
Climate change may be occurring even faster than first thought.
That is according to a ground-breaking new study by Dr. Clayton Magill from the Lyell Centre at Heriot-Watt University.
Scientists measured the vast migration of sea bed materials such as clay and sand, a process that occurs over thousands of years.
The research found that constant movement resulted in the erosion of ancient fossils trapped within the ocean floor and that these fossils release their harmful carbon dioxide, which is a strong greenhouse gas.
Researchers previously thought that the rate of erosion on these fossils was significantly slower – hence climate change was slower.
Now the study, published in Nature sheds new light on the how fast climate change is actually happening.
Dr. Clayton Magill said: “There are some outstanding gaps in current knowledge about the imminent impacts of climate change on ocean environments and in this study we show that there are still large unknowns in the major sources of fossil carbon on earth.

“We don’t know how much carbon is trapped in the ocean but now we’ve proven the process, it could pose catastrophic threat to earth’s climate.”
The study also raises questions about how best to deal with marine pollution across the globe.
Dr. Magill continues: “We found that many pollutants stick to clay and there are issues if polluted clays transport over time from one region to another.
“For example, polluted clays from China can be transported by time to Vietnam – and transport times might be decades or centuries.
“There’s still a lot to discover about climate change and marine pollution over time, but this study highlights the fact that climate change could be happening a lot faster than academics once thought possible.”
