This #FullDiskFriday, we’re showcasing Earth’s land surface temperatures (LSTs) captured by NOAA's #GOESEast (#GOES19) 🛰️ following a week of extreme heat. GOES-19 used infrared observations to measure LST, but clouds can block its view of the surface. Areas shown in gray indicate where temperature data was unavailable.

This animation shows sea surface temperature differences compared to average conditions between January and mid-July 2026 using data from satellites, including NOAA’s geostationary and polar-orbiting satellites. Areas where temperatures are unusually high for an extended period of time indicate marine heatwave conditions. Understanding the duration, intensity, and spatial coverage of marine heatwaves is essential as they can significantly impact marine life that coastal communities and economies rely on.

Y'all see this swirl over the Mediterranean passing south of Benghazi? That's not a hurricane – it's a Medicane. Yes, that's a real term. The word is a portmanteau combining "Mediterranean" and "hurricane." The Mediterranean is too small to support barotropic (tropical cyclones) the scale of conventional hurricanes AND is too far north to support a truly tropical cyclone anyway. Moreover, water temperatures are too cool. (Most tropical cyclones exist over sea surface temperatures of 78 degrees or warmer; the current water temperature off the coast of Libya is about 63 degrees.) Medicanes can and occasionally do reach hurricane strength. The strongest on record was Medicane Ianos, which impacted Greece between September 17-18, 2020. It briefly became the equivalent of a tiny Category 2 hurricane with winds of 95 mph. On rare occasions, a nontropical low can meander over the Mediterranean, and a storm can form that takes on some tropical characteristics. Unlike nontropical cyclones, which are common at the mid-latitudes, medicanes feature a warm core. That requires warm sea surface temperatures. A 2016 study found that medicanes are likely to become significantly stronger by the end of the century in response to warming sea surface temperatures. Tthe researchers found a likelihood for "a higher number of moderate and violent medicanes.” Since 1980, Mediterranean sea surface temperatures have increased between 1 and 2 degrees.

Marjorie Taylor Greene tried explaining away Climate Change by arguing that no one paid taxes during the Ice Age: Let me break this down a little bit for you: - The last ice age began approximately 2.6 million years ago and peaked approximately 20,000 years ago. - At its peak, temperatures were estimated to be approximately 10°F cooler than they are today. - That equates to a temperature rise of 0.05°F per century over 20,000 years. - Over the last 100 years (1 century) alone, the average surface temperature has increased by 1°F - This is 20 times faster than it had gained on average over the 190 centuries prior. - What changed? Industry and the burning of fossil fuels. Carbon dioxide causes a greenhouse effect, keeping heat in the Earth's atmosphere and surface. The levels of CO2 have increased drastically over the last century. FACTS matter and so do educated politicians.

Yesterday while mowing the assholes were in the sky, but the trails were different this time… they had a little squiggles. Picture to the right, I just took It. They’re out there spraying as I type… …because it’s gonna rain this evening and we’re gonna have horrific winds. Straight line winds… Betty what are those? Straight-line wind refers to a powerful, fast-moving surface wind that lacks a rotational pattern and can cause widespread damage, often resulting from thunderstorms. These winds can reach speeds of over 100 mph and are typically associated with downbursts. Then followed by a freeze again… Who can tell Betty what will happen to all the fruit trees and bloom right now? The freeze is expected to occur in parts of the Midwest and East Coast of the United States early next week, specifically from March 19 to March 21, 2026. During this timeframe, temperatures are predicted to drop significantly, with highs falling into the 30s and 40s degrees Fahrenheit, following a period of unusually mild temperatures. How is it that these weather people can predict the wind starting in a hour… Because it’s controlled 🙄 Protect & Prepare 💖🫵🏻

Big dawg El Niño coming this summer and fall! This is a bit science-y… but easy I promise. So follow along. You are looking at a vertical cross section of the tropical Pacific Ocean at the Equator with depth downward deep into the ocean. Left side is west near Asia. Right side is east near South America. It’s where we measure El Niño, the king control knob of the climate. One main way we know it’s coming is “subsurface heat”. See the dark red shades moving east under the surface and rising upward? That’s the El Niño developing! El Niño is a build up of hotter than normal water on the surface Eastern Tropical Pacific Ocean. What’s cool (or hot) is that the water comes from the West Tropical Pacific. During cool La Niña years it’s like a piggy bank. The West Pacific hoards and stores the heat near Asia. Then every couple-few years that warm water sloshes back East. It first appears under the surface where we measure it. It surfaces in late spring and El Niño grows in Summer to fall. You can tell by the magnitude of warm subsurface water that this looks like a biggie! So how will it impact us? For one, it typically subdues Atlantic hurricane season. That doesn’t mean no storms - just less active than it would have otherwise been. Also it releases lots of Heat… so it super charges heat waves around the planet and floods too - it all tends to be more immense and intense. And you can bet Earth will experience its hottest days on record coming later 2026 into 2027. El Niño is one of the biggest climate forces on Earth and it has a profound impact on world-wide weather because of all the heat released into the atmosphere from the ocean.

In the hellish furnace of Venus—where surface temperatures soar to ~460–470°C (860–880°F) and pressure crushes at about 92 times Earth's—the Soviet Venera 14 lander achieved something extraordinary: it not only survived long enough to operate but also captured one of the only direct audio recordings ever made on another planet.Launched in 1981 and touching down on March 5, 1982, Venera 14 endured for roughly 57 minutes on the scorched plains before succumbing to the extreme conditions. Among its suite of instruments was a microphone (part of the Groza-2 package, shared with a seismometer), designed primarily to detect atmospheric sounds, possible thunder-like electrical discharges, and mechanical operations.The resulting audio—transmitted back to Earth—includes eerie, low-frequency rumbles: the relentless howl of super-dense winds whipping across the surface (moving slowly but with immense force, equivalent to hurricane-strength gusts in our thinner air), mechanical thuds and whirs from the lander's own activities (like the explosive release of its camera lens cap and the grinding of its drill attempting to sample the basaltic rock), and subtle vibrations as the probe settled and strained under pressure.These are among the very first (and still among the only) sounds ever recorded from another world's surface—preceding even the wind sounds picked up by later missions like InSight on Mars or Dragonfly concepts. Venera 13 (which landed days earlier on March 1, 1982) also carried microphones and returned similar recordings, surviving longer at 127 minutes and capturing comparable wind and mechanical noises.The raw, noisy tapes have been cleaned up, enhanced, and widely shared over the decades—often layered over simulated landing visuals—giving listeners a haunting glimpse into Venus's alien soundscape: a constant, oppressive roar punctuated by artificial intrusions from humanity's brief other probe has returned surface audio from Venus since the Venera program ended in the early 1980s. Future missions like NASA's DAVINCI+ or ESA's EnVision may revisit the planet, but for now, these faint, crackling echoes remain a rare auditory relic from our solar system's most inhospitable world.Image credits: Soviet space program archives (Venera 14 lander illustrations and surface panoramas from the mission); enhanced audio visualizations and modern renderings of the Venusian surface.

Did you know the James Webb Space Telescope isn’t orbiting Earth at all? The James Webb Space Telescope operates near the Sun–Earth L2 point, about 1.5 million km from Earth. From there, the Sun, Earth, and Moon stay on the same side of the telescope, allowing its giant sunshield to block their heat and light at the same time. That keeps Webb cold and stable enough to detect extremely faint infrared signals from deep space. Because of this, Webb can peer through clouds of cosmic dust and observe galaxies whose light has traveled for more than 13 billion years. Every image it captures is not just a view across space, but a look back into the early history of the universe.

El Niño is born! Destined to be the biggest in 150 years +?? NOAA declares: El Niño Advisory This morning conditions in the Eastern Pacific met the criteria for El Niño. This means Sea Surface Temps reached a certain level above normal, and the ocean and atmosphere “coupled” meaning they are now working in tandem to produce impacts. This event is widely advertised by models to be potentially the strongest on record. El Niño takes very hot water stored in the deep tropical west Pacific, pushing it east and up to the surface, lofting that heat into the atmosphere, which supercharges weather events and throws the climate off-kilter. This typical means more intense heatwaves & floods, but also it restrains the Atlantic hurricane season. So its impacts are both good and bad. One thing seems virtually certain: the heat released into the atmosphere will make for some unprecedented events through 2027, and on top of longterm warming, the hottest global temperatures in many tens of 1000s of years. #ElNino #florida #storm #heatwave #flood #drought

🚨 BREAKING: MIT researchers just built a quantum sensor that can measure multiple properties at once. That matters more than it sounds. Most solid-state quantum sensors have to measure things one by one: magnetic field, temperature, strain, frequency, phase. But reality doesn’t wait its turn. MIT used entangled qubits inside a diamond defect to measure multiple signal properties in a single shot. Read that again. This means Faster measurements Less error from repeating experiments Better sensing inside complex systems like materials and living cells The wild part? They did it at room temperature. Not in some ultra-cold, impractical lab-only setup. In a platform that could actually matter for real-world sensing. Inside a tiny defect in diamond, quantum correlations were used to pull out: amplitude frequency detuning phase all from the same measurement. That’s a big shift. Because the future of quantum tech isn’t just quantum computers. It’s quantum devices that can see more of reality at once. So the real question is When sensors stop measuring one thing at a time… how much of the hidden structure of matter becomes visible? Follow me for more physics breakthroughs that actually matter.

In the scorching heat of Rajasthan, where stepping out can feel unbearable, a native tree quietly offers relief. Locals call it Mithi Jal. Science calls it Salvadora oleoides. And many now call it a natural “desi AC.” With its dense, evergreen canopy, this hardy desert tree creates its own microclimate, with temperatures under its shade recorded to be up to 5–8°C cooler than the surroundings. In regions where water is scarce and electricity isn’t always reliable, this natural cooling isn’t just comfort, it’s survival. For generations, people and livestock have rested under its shade, finding relief in the middle of extreme heat. In a world racing to build climate solutions, Mithi Jal stands tall as a reminder: Some of the most powerful innovations don’t need to be invented, they need to be protected.

🌊 El Niño in the tropical Pacific continues to strengthen According to NOAA/CPC, sea-surface temperatures off the coast of Peru and around the Galápagos Islands are more than 3°C above the long-term average. According to the WMO’s monthly Global Seasonal Climate Update, El Niño is expected to continue strengthening and develop into a strong event during August–October 2026. A positive Indian Ocean Dipole is also forecast. During this phase, the western tropical Indian Ocean is warmer than average, while the eastern part is cooler than average. The WMO warns that a strengthening El Niño increases the likelihood of heatwaves, drought, heavy rainfall, and other extreme weather events, with impacts varying by region. 🌡️ Above-normal temperatures: expected across most inhabited land areas of the world. 💧 Wetter-than-normal conditions: western North America, central South America, southern Europe, and North Africa. ☀️ Drier-than-normal conditions: Central America, northern South America, northern Europe, parts of central Africa, India, and southern and eastern Australia.

One of the least understood systems in aerospace manufacturing is the BeAM Magic 800 directed energy deposition platform used for printing turbine nozzles and hot-section components. It uses a laser to melt metal powder or wire feedstock, depositing material layer by layer with positioning accuracy in the 20-50 micron range, building complex nickel superalloy structures that can withstand extreme thermal cycling. A full industrial setup can cost $800,000 to $1.5M+ The materials are not simple metals, but aerospace-grade alloys like Inconel 718 and 625, designed to survive temperatures above 700-900°C while resisting creep and oxidation. But the printed part is never the final part. Critical sealing surfaces, flanges, and precision interfaces are still finished on CNC machines to tolerances under 10 microns, because additive alone cannot guarantee repeatable surface integrity under flight loads.

🚨 SCIENTISTS JUST FOUND AN ANCIENT OCEAN FLOOR WRAPPED AROUND EARTH’S CORE. Using seismic waves recorded by stations buried in Antarctic ice, researchers have created the highest-resolution map yet of the boundary between Earth’s mantle and outer core nearly 3,000 km beneath our feet. They discovered thin but widespread patches of dense material that dramatically slow down seismic waves. The most likely explanation: these are fragments of ancient oceanic crust that sank into the deep mantle long ago and have been moved around by convection currents for hundreds of millions of years. In some places, these structures rise up to five times higher than Mount Everest. Why this matters: • It reveals that Earth’s deep interior is far more complex and dynamic than we thought • These patches likely influence how heat flows from the core into the mantle, which affects mantle convection and volcanic activity • They may also play a role in the behavior of Earth’s magnetic field, which is generated in the outer core • Understanding this boundary helps us better model how our planet has evolved over billions of years The deeper implication: We usually think of the deep Earth as relatively simple layers. This research shows that the core-mantle boundary is more like a rugged, geologically active landscape with ancient “mountains” made of recycled ocean floor. It’s a powerful reminder that Earth is a single, interconnected system what happens at the surface (like plate tectonics) can eventually end up reshaping the deepest parts of our planet, and vice versa. We’re still only beginning to map the true complexity hidden beneath our feet. How do you think discovering ancient ocean crust at the core-mantle boundary changes the way we should think about Earth’s internal dynamics? Follow for more frontier Earth science and discoveries about our planet’s hidden interior.

"Do not miss the once in a lifetime chance to see the largest collection of 329 ‘Taihaku’ cherry blossom trees in the entire world all in their two week blossom window this spring at Alnwick Garden. Such a rare sight and no where else in the world has this beauty at such a scale but right here in Northumberland you can visit the cherry tree orchard and take it all in. The view is breathtaking and something you have to see with your own eyes. In 1926 Captain Collingwood Ingram was invited to Japan to give a lecture to the Sakurakai (cherry society). Whilst there he was shown a picture in an 18th Century book of a large, white cherry blossom that had become extinct. He recognised the same blossom on a cherry tree which had been imported to a Sussex garden in 1899 and was able to take cuttings from it and reintroduce the lost Taihaku to Japan in 1932.All of the Taihaku in cultivation today are off-spring of that cherry tree in Sussex!" -Emma.

The view is breathtaking and something you have to see with your own eyes. In 1926 Captain Collingwood Ingram was invited to Japan to give a lecture to the Sakurakai (cherry society). Whilst there he was shown a picture in an 18th Century book of a large, white cherry blossom that had become extinct. He recognised the same blossom on a cherry tree which had been imported to a Sussex garden in 1899 and was able to take cuttings from it and reintroduce the lost Taihaku to Japan in 1932.All of the Taihaku in cultivation today are off-spring of that cherry tree in Sussex!" -Emma.

🚨 SOUTH KOREAN SCIENTISTS JUST CREATED HOLLOW SILICON NANOTUBES THAT TRAP HEAT AND TURN WASTE ENERGY INTO ELECTRICITY. Researchers at POSTECH have developed a new hollow silicon nanotube structure that dramatically reduces thermal conductivity. By turning solid nanowires into microscopic pipes, they trapped heat-carrying particles (phonons) inside the tubes, cutting thermal conductivity by 70% compared to solid wires. Even when both structures had the same surface area, the hollow nanotubes still ran 33% cooler. This phonon localization effect previously thought to require extreme cold or exotic materials was achieved at near-room temperature using simple silicon nanotubes. Why this matters: • Waste heat from data centers, EV batteries, factories, and electronics is currently lost this could capture and convert it into usable electricity • The technology uses abundant, cheap silicon instead of rare and expensive materials like bismuth and tellurium • It’s highly compatible with existing semiconductor manufacturing, making large-scale production more realistic • It solves a long-standing problem: silicon is great for chips but terrible for thermoelectric energy conversion The deeper implication: This breakthrough shows that clever nanoscale engineering can unlock new capabilities from ordinary materials. By controlling how heat moves at the atomic level, researchers are opening a path to more efficient energy recovery systems without relying on scarce resources. As AI and computing power keep growing, finding ways to recycle the massive amounts of waste heat they generate will become increasingly important. How significant do you think waste-heat recovery technologies like this could become in the next decade? Follow for more frontier materials science and energy innovation.

Spain is renowned for its incredible Islamic heritage, a beautiful legacy that dates back to when the Islamic Empire ruled and conquered the Iberian Peninsula in 711. By 732, the enchanting Al-Andalus was born, leaving behind what is now considered Europe’s finest collection of Islamic art. Architecture and art are inextricably linked in Islamic culture. Islamic art showed the status of the caliph, and huge sums were spent on its production. This is evident in Andalusia. Islamic art in Andalusia is described in several terms, each with a unique meaning. “Moorish art” is the most commonly used term. A less well-known term is Mudéjar, which describes the architecture created for Christian patrons by Muslim craftsmen. The Moors originally “Maurus” in Latin, was used to describe Berbers and inhabitants of North Africa. Later, it referred to Muslims of Spain until King Phillip III of Spain decreed their expulsion. Moorish art is characterised by its intricate and complex geometry, floral motifs, and horseshoe arches as well as its use of shade and light as can be found in Alhambra, The Alcazar of Seville & The Giralda Tower among others. Even though the Muslim areas in Spain were later seized, the influence of Islamic architecture and art continues to live on and inspire… Granada, Andalusia Video Credit goes to @4ilaras
