WTF is Taking place? An Overview – Watching the World Go Bye

2023-06-12 10:26:09

As of June 10, 2023, worldwide knowledge confirmed the outstanding concurrence of three dramatic local weather occasions.

The primary WTF is within the Antarctic, the place sea-ice extent is setting document lows day by day, now absolutely over 2 million kilometers beneath the 1991-2020 imply. This isn’t some one-off occasion. A decline like this has lengthy been predicted. The influence is that there’s a lot extra open ocean than regular for this time of 12 months. Open ocean means the power to soak up incoming photo voltaic radiation, and which means additional heating in a widely known suggestions loop.

Utilizing JAXA data, I ready a picture as an instance simply how loopy this second is. The way in which you learn the picture beneath is that every horizontal blue wavy line is a 12 months’s value of measured sea-ice extent. Beginning with the common extent over the interval 1991-2020, I merely examine every day’s extent with that common and plot that time on the 12 months’s blue line.  The years proven on this picture are 1991-2023, with 2023 in purple to spotlight simply how uncommon it’s. For these of you with eager eyes, the dip on the decrease proper corresponds to the 12 months 2016, the 12 months after that final El Niño, and a harbinger of what might lie forward.

The second WTF regards world 2-meter floor temperatures – the place on June 10, for the third consecutive day temperatures breached the 1.5°C barrier (above the 1850-1900 IPCC baseline). This isn’t the identical as breaking the Paris 1.5°C barrier, which requires the long-term planetary common to be above 1.5°C. Neither is it the identical as breaching 1.5°C for the 12 months. These temperature spikes have occurred many instances earlier than. However this breach does act as a benchmark for the inevitable future that’s coming. For many who like statistics, on June 9, world 2m temperatures reached 4.8 commonplace deviations above the 1979-2000 imply.

And the third WTF is maybe the furthest from any notion of normalcy. WTF is going on to the world’s oceans, and particularly the North Atlantic? Ocean temperatures have been setting unprecedented day by day information, spiking to highs which might be surprising local weather scientists, as they search for doable causes.

Here’s a image from that provides a way of world sea floor temperature anomalies on June 10:

The next reveals day by day world sea-surface temperature (SST) anomalies over the area 60S-60N., by June 10, (utilizing this data):

And right here is the true WTF picture — the North Atlantic SST anomaly (utilizing this data):

Since I first printed the North Atlantic image on Twitter, this picture has gone viral internationally. As of this writing, it has attracted over 2.6 million views on Twitter and has been featured in media worldwide. That’s how hungry individuals are to know what’s taking place. That’s why I’m penning this put up.

The CERES website publishes month-to-month updates to what’s generally often known as the Earth Power Imbalance or EEI. This knowledge permits us to know the distinction between incoming photo voltaic radiation and outgoing radiation from all sources. That distinction is the efficient fee of heating on the planet. As of March, 2023, on an annualized foundation, the EEI was 1.61 Watts per sq. meter. That may not sound like rather a lot, however on a world foundation it’s about equal to the power launched from 13 Hiroshima sized nuclear bombs exploding each second.

As you in all probability know, the planet’s oceans soak up about 89% of the surplus warmth generated by world warming. Over the past three La Niña years on common, the ocean’s share of the EEI has been equal to about 9.8 Hiroshima bombs per second, or about 930 million Hiroshimas in whole. The ocean is sizzling and getting hotter on a regular basis, however till now we haven’t instantly seen that warmth.

There’s an apparent cause to elucidate among the ocean heating that’s taking place proper now: the unexpectedly fast onset of El Niño, which usually drives large floor heating of the Japanese tropical pacific. However what about different components of the ocean? What concerning the North Atlantic.

Right here’s the place issues get esoteric. As of January 1, 2020, the Worldwide Maritime Group put a restrict on the sulfur content material in delivery fuels, decreasing the worldwide higher restrict on sulfur content material from 3.50% to 0.50%.  Here is a link to an article describing this variation. This diminished restrict was necessary and led to over a 75% drop in sulfur oxides. Whereas nice for the surroundings in lots of respects (e.g. much less acid rain and ocean acidification), there was additionally a not-so-unexpected consequence.

Sulfate aerosols, together with atmospheric particulates, will increase the quantity of incoming daylight mirrored away from the Earth, successfully dimming the planet’s floor. Lasting solely weeks to months within the ambiance, these sulfate aerosols have to be frequently replenished to have their cooling influence. The IPCC means that present sulfur aerosol ranges are contributing within the neighborhood of 0.5° C to whole world cooling, offsetting warming that might in any other case quickly happen. That is generally often known as “global dimming.

By cleansing up delivery fuels, large areas of the world’s oceans that have been protected against heating by delivery sulfate aerosols are actually experiencing fast warming. This contains the principle delivery routes between Asia and the Western US in addition to the key routes from the Easter US to Europe and the Center East. And that’s the place the warming is going on. This fast heating is named “termination shock,” and it seems to be what’s taking place proper now.

This picture, shared by Leon Simons on Twitter, highlights the areas of the oceans most impacted by this sudden change in sulfur content material:


There’s one other doable enter to this heating worthy of notice. Mud from the Sahara usually blows west this time of 12 months, blocking incoming radiation whereas trapping present warmth. Up to now this 12 months the mud has not come. The shortage of mud is notable and is also a direct reason for among the North Atlantic heating. For extra, here is an article on the topic.

It’s my opinion that the mix of years of ocean heating generated by the EEI, heating in Antarctica attributable to open ocean, shifts in winds and floor heating attributable to El Niño, lack of Saharan mud, and IMO 2020 have collectively triggered unprecedented ocean floor warming. I don’t have the experience to place these in any explicit causal order, however that doesn’t actually matter. The results are clear.

As we enter Northern hemisphere summer time, massive areas of the planet will expertise document heatwaves, fires, storms and flooding. These occasions will set information in depth, length and frequency. The planet’s general temperature will spike to new highs for the fashionable period, with 1.5°C in sight for 2024.  Antarctic polar sea-ice will proceed its retreat from “regular”, exposing extra open ocean to incoming photo voltaic radiation and heating. Crops will fail. Infrastructure will break past restore. Local weather migration will spike. And all of that is already taking place. In the meantime, carbon dioxide from anthropogenic sources continues to spew at a near-record rate, whereas the Paris restrict of 1.5°C requires these emissions be diminished about 7% per 12 months for the subsequent decade.

And that is all taking place within the midst of the present political and social chaos, whereas the world makes an attempt to recuperate from a pandemic that’s nonetheless ongoing however ignored by world media.

These subsequent two years are a pre-amble to what it is going to imply for the world to go the Paris 1.5°C barrier. The top of world industrial civilization is the place we’re headed proper now, not at some future dystopian second. I want I had a hopeful phrase to finish with. However I don’t.
