This is so unusual. That's a *huge* amount of energy being transferred to the atmosphere. Expect extreme temperature and storm records. Just the top few metres of our oceans store as much energy as the entirety of our atmosphere. I'm very concerned for later this year into 2024.
UK friends & others in northerly latitudes: I highly recommend going somewhere dark tonight.
This is the strongest solar storm in 20 years.
There are clear skies for most of the UK.
A once-in-a-lifetime opportunity to see #aurora for many.

This animation shows *SIX* coronal mass ejections from the sun. All of which on a trajectory for Earth. The sun (the white circle in the centre) is blocked out to protect the sensor. The two bright spots are Jupiter (left) & Venus (right).

The solar flares are emanating from this gigantic sunspot (AR3664)... For scale, the sunspot is 15-Earths wide.

Spring is always beautiful... especially in infrared!
This photo was taken with a camera I converted to be sensitive to IR wavelengths of light that plants reflect in abundance when they're healthy. We see green, but that's a small fraction of the light reflected by plants.

The sensors on digital cameras are made of materials that are sensitive to visible light that an unimpaired human eye can see, but also infrared wavelengths beyond that sensitivity. Camera manufacturers install a filter to block that unwanted light, but you can remove it.

The clearer the sky, the darker it looks. The camera only picks up IR light, which is far away from blue visible light in the electromagnetic spectrum. You can see the half-Moon in this shot. It would have been hard to see with the naked eye, shrouded by a bright blue sky.

I've said it before and I'll say it again:
"This is a *huge* amount of extra energy being transferred to the atmosphere. Expect extreme temperatures and storm records (again). Just the top few metres of our oceans store as much energy as the entirety of our atmosphere."

This really is urgent. Action is needed *NOW* & it needs to be of Manhattan Project/Landing on the Moon speed & scale.
Earth's energy balance is out of kilter:
During 2020-23, Earth accumulated ~68 zettajoules (ZJ) of energy.
During 2007-10, Earth accumulated ~28 ZJ.
The extra energy gained by Earth in the past three years is similar to the amount gained between 1970 & 1985.

Why is the energy imbalance growing?
- emissions from fossil fuels lead to an enhanced greenhouse effect, reducing how efficiently Earth loses heat to space
- at the same time we're improving air quality, which reduces the cooling effect of aerosols that reflect sunlight

Shipping fuels were heavily regulated recently. They produce reflective aerosols & are also known to increase cloud cover, shading the oceans.
Between 2015-20 & 2020-23, the absorbed solar radiation anomaly tripled in the North Atlantic, the North Pacific is up by 70%.

How did historic climate events inspire vampire mythology, Shelley's Frankenstein, Turner's famous sunsets, & even Stradivari's violin craftmanship?
Here's a short thread on these climate-artistic connections that span literature, paintings, and music.

Before the dominance of fossil fuel greenhouse gases as the main driver of climate change in the past century, noticeable decadal-scale change was generally a function of volcanic activity (episodic cooling) & solar activity (inactive periods linked to regional cooling).

The 'Year Without a Summer' is perhaps the most famous example. The 1815 explosive eruption of Tambora (Indonesia) led to a year-long 'volcanic winter' with famines from China to Europe. The European summer of 1816 was particularly cool.

- Domestic solid fuel burning is now the largest source of UK particulate pollution, overtaking traffic
- Government monitoring networks are not designed for static suburban pollution sources
- Citizen science is filling the gaps
Low-cost and reliable sensors are enabling communities to set up their own monitoring networks to raise awareness of pollution hotspots that are missed by national or local authority air quality monitoring:
