What Does The Slowdown In Arctic Sea Ice Melting Actually Mean For Climate Change?

What Does The Slowdown In Arctic Sea Ice Melting Actually Mean For Climate Change?
Melting sea iceDespite a heatwave-heavy year that climate change experts have chalked down to climate change, scientists have found something many of us might not have expected in the Arctic. There’s been a “dramatic” slowdown in the melting of Arctic sea ice over the past 20 years, the decline of which is a major concern for climate scientists.The research shows that there’s been a “minimal” increase in ice melting since about 2005, meaning it’s melting at a much slower rate than before this period (between 1979 and now, the amount of Arctic sea ice available in September, when it’s at its lowest, has halved).What’s more, the paper says this trend “could plausibly persist another five to 10 years.” But we know that CO2 emissions have continued to rise, that the earth is getting unsustainably hot, and that, in short, global warming is only expected to get worse. So how does this change make sense, and what does it actually mean about the risks of climate change?The change is likely only temporary Speaking to HuffPost UK, Johan Griffiths, chief meteorologist at environmental solutions company KISTERS, said: “The most crucial thing to understand is that, hopeful as it may seem, the recent slowdown in Arctic sea ice melt doesn’t mean climate change is easing.“Instead, what we’re seeing is the influence of the Earth’s natural climate variations. These shifts in ocean and atmospheric patterns can, for a time, offset the effects of global warming.” The decreased melting of Arctic sea ice is probably due to changes in ocean currents, which have recently seen less warm water pass by the sea ice.But this is part of the natural cycles of the Atlantic and Pacific oceans – these current cycles are not going to last forever.“The facts are clear: Arctic sea ice today still covers far less area than it did a generation ago, and once these natural cycles swing back the other way, the rate of melting could pick up again, potentially even faster than before,” Griffiths said. Indeed, the researchers expect ice melting to happen at a “faster-than-average” rate once these changes stop. “This slowdown is merely a temporary reprieve, and the long-term picture remains concerning, as we will likely continue to see ice loss driven by the accelerating change in our climate.” The ice is not rebuildingWe still have far less Arctic ice than we should due to global warming – ice which has not regrown in this 20-year cycle.And though the melting seems to have slowed, Professor Andrew Shepherd told The Guardian: “We know that the Arctic sea ice pack is also thinning, and so even if the area was not reducing, the volume still is. Our data show that since 2010, the average October thickness has fallen by 0.6cm per year”. This is not a sign that global warming is not real or is not dangerous. As the scientists note, “Overall, while it may sound surprising that Arctic sea ice loss has slowed down even as global temperatures hit record highs, the climate modelling evidence suggests we should expect periods like this to occur somewhat frequently.” Related...Our Four Seasons Are Breaking Down – Here’s What Climate Scientists Say Comes NextThe UN's Decision To Let Countries Sue Each Other Over Climate Change Is A Regrettable NecessityFixing UK Housing Must Be A Priority As We Adapt To Our New Climate Reality, MP Warns
