Antarctica just registered a temperature above 20º C (68ºF) for the first time in recorded history, according to climate scientists.
The recent record-breaking warm temps in Antarctica are raising concerns among climatologists that the world’s greatest repository of ice may become far more unstable, far more soon, and set off a cascading series of catastrophic changes that could abruptly change life on Earth.
“We are seeing the warming trend in many of the sites we are monitoring, but we have never seen anything like this,” said Carlos Schaefer, who works on Terrantar, a Brazilian government project that monitors the impact of climate change on permafrost and biology at 23 sites in the Antarctic.
From The Guardian:
The 20.75C logged by Brazilian scientists at Seymour Island on 9 February was almost a full degree higher than the previous record of 19.8C, taken on Signy Island in January 1982.
It follows another recent temperature record: on 6 February an Argentinian research station at Esperanza measured 18.3C, which was the highest reading on the continental Antarctic peninsula.
These records will need to be confirmed by the World Meteorological Organization, but they are consistent with a broader trend on the peninsula and nearby islands, which have warmed by almost 3C since the pre-industrial era – one of the fastest rates on the planet.
Scientists, who collect the data from remote monitoring stations every three days, described the new record as “incredible and abnormal”.
Antti Lipponen of the Finnish Meteorological Institute created this troubling but unsurprising chart of almost 140 years of temperature anomalies by country. The data used was from the NASA GISS, Land Ocean Temperature Index. You can probably guess what will happen.
In ten years, scientists hope to have mapped the entire ocean floor in high resolution. This week, the Nippon Foundation-GEBCO Seabed 2030 Project announced that they’ve completed 20 percent of the map. A full mapping to “modern standards” is useful for conservation and also to support scientific understanding of ocean systems, weather, tsunami wave propagation, […]
Twenty-five experts have issued a warning about the potentially cataclysmic consequences of the rapidly shrinking insect population, reports The Guardian. In a two-part article for Biological Conservation, the scientists wrote: “The current [insect] extinction crisis is deeply worrisome. Yet, what we know is only the tip of the iceberg.We know enough to act immediately. Solutions […]
It’s easy to be instantly dismissive about most Bluetooth speakers, especially small travel-sized units. Over the past few years, makers of every shape, size, and variety have started pounding out Bluetooth speakers, many barely able to sound much better than your smartphone speaker, let alone provide the bass and volume heft of legitimate portable speakers […]
Did you know that you are free to change your auto insurance at any time? Maybe you do know that, but don’t want to deal with the inconvenience of changing providers. Or maybe you simply already think you have a great deal. The fact is that your car insurance is one of those expenses that […]
According to researchers, stay-at-home orders in the US and around the globe are helping those working from home grab an extra 15 minutes of sleep per night. For college students, it’s even up to 30 extra minutes each night. Meeting your quality sleep threshold is actually one of the greatest indicators of your overall health. […]
