When the snow melts, ice melts and the sea level rises, but that doesn’t mean glaciers are melting faster.
Scientists have been studying the issue of glacial ice melting for decades.
But the latest data, published in the journal Science Advances, has been quite surprising.
“I’m very pleased with the new data,” said Robert D. Hare, a glaciologist at Columbia University who co-authored the study with co-author Christopher B. J. Schulze, a hydrologist at Columbia.
The study was funded by the National Science Foundation.
The researchers collected a variety of data, including sea-level data, ocean heat content and sea ice cover, as well as temperature, precipitation and precipitation intensity.
From these, they came up with a “temperature sensitivity” for ice melt, which is how much ice is melting when compared to the average annual rate of warming.
The team used this temperature sensitivity to calculate the rate of ice melting, which they determined is about 4 percent per year.
It’s the fastest rate of melt since the early 1970s.
It means that glaciers are now melting at twice the rate that researchers expected.
What’s more, the rate is still well below the rate predicted by models, which said that ice melt would increase by 20 percent per decade.
“The rate of sea-ice loss is slowing,” Hare said.
“It’s slowing down, but it’s not slowing down by much.”
The researchers looked at sea-levels and ice sheets around the world.
“Sea-level is changing very slowly.
You can’t see it very well,” said Dr. James K. Tettleton, a professor of geosciences at the University of Colorado at Boulder.
“But it is slowly changing.
It was expected to change by about 10 meters per century, which was the current rate of change, but the rate has slowed down by about 5 meters per decade.”
Hare said this trend is a result of the slow rate of ocean heat uptake, which the researchers estimated is about 0.5 millimeters per year, or about 0-2 millimeters in each year.
“We need to keep doing this, because we can’t have this warming accelerating any further,” Hare told The Huffington Store.
“If the ocean heat is going to accelerate, it’s going to be accelerated by the greenhouse effect.”
The warming of the planet is going on faster than we thought.
And scientists don’t know how to slow it down.
The global warming that has been observed over the past several decades has slowed.
So what can we do about it?
“What we need to do is take steps now to reduce greenhouse gases,” Hare added.
“There are a number of things we can do to mitigate warming.”
He said there are ways to slow the warming of our oceans, including carbon dioxide emissions and the use of renewable energy.
“These are things we should be doing, but we don’t,” Hare wrote in an email to The Huffington Watchdog.
“They’re good steps, but they aren’t enough.
And it’s time to use all the technologies we have, like wind turbines, to reduce emissions, which are a big part of climate mitigation.”
