Heatwaves at both Earth’s poles alarm climate researchers

Over the weekend, temperatures at both the Earth’s poles soared to between 30C and 40C higher than expected levels. If this becomes the norm, researchers are seriously concerned about an abrupt climate breakdown.

At this time of year, the Antarctic should be rapidly cooling after its summer while the Arctic gradually emerges from its winter months. Instead, both poles are experiencing ‘unprecedented’ heatwaves that have climate researchers on high alert.

Over the weekend, temperatures in Antarctica warmed to 40C above the norm in places and the Arctic pole hit peaks of 30C above expected levels. For both icy plains to be warming simultaneously like this really isn’t good.

In the first – of what looks like will be many – chapters of the IPCC report on climate change, the international organisation warned of a climate breakdown of which tell-tale signals were rearing their head already.

Chief among them was polar melt on an irreversible scale, which could realistically be a decisive trigger point for a complete climate breakdown. What we perhaps underestimated, is how close to that precipice we reside today.

Scientists have warned that the weekend’s recordings were ‘historic,’ ‘unprecedented,’ and ‘dramatic.’ All words you don’t want to hear when discussing a potential catastrophe… who’s that playing Glass Animals?

One weather station in the North Pole noted its hottest recording by some 15C, while another costal station prepped for March deep freezes was 7C above zero.

Mark Maslin, a professor of climate science at University College London, said: ‘I and colleagues were shocked by the number and severity of the extreme weather events in 2021 – which were unexpected at a warming of 1.2C.

‘Now, we have record temperatures in the Arctic which, for me, show we have entered a new extreme phase of climate change much earlier than we had expected.’

These concerning developments follow on from a series of troubling temperature increases in 2021. In the US Pacific north-west, heatwaves climbed to a scorching 50C.

Elsewhere, scientists reported on record lows of sea ice in the Antarctic Ocean, since measurements began back in the 90s.

By all accounts, we’re exceeding predictions from climate researchers, and you can bet a new level of urgency will be expressed in future reports. Rightfully so, too.

If we are to continue losing sea ice and glaciers, the dangers are two-fold; not only are we looking at rising sea levels, which will decimate vulnerable regions, we will also tip the planet’s energy imbalance drastically and raise temperatures even higher across the globe.

The less ice coverage we have across our oceans, the less sunlight will be reflected back from our atmosphere. Without ice to coat our dark waters, heat radiation will linger and slowly shrink our poles away entirely.

In the days and weeks ahead, this news will no doubt cause a stir between climate NGOs and policymakers. 2030 is suddenly looking a long way off.
