With climate, perspective over time is important. This graph shows estimated global average surface air temperatures for the last couple thousand years based on ice core proxies and since 1850 in red based on temperature measurements. Source: oz4caster.wordpress.com/2014/12/29/hol…

Severe thunderstorm yesterday evening dumped 2.6" rain with wind gusts 60+ mph extrapolated to 10m from our poorly exposed backyard weather station anemometer at ~2m. No hail thankfully. Reports of trees down in nearby Georgetown TX. Will survey neighborhood on walk this morning.

@TonyClimate Elon might be right. Putting data centers in space could make sense from heat and water issues. Not sure if it is economical.

@TonyClimate Would be interesting to see how they look in IR from above. Data Center Heat Islands?

Just updated daily CFSR global surface air temperature graph thru May 15 and added NCEI and GISS to monthly graph thru April. Overall downward trend continues since Hunga Tonga induced peak in late 2023. Looming El Niño may produce a big peak later this year and into early 2027.

Yes, so true!

CO₂ is a footnote in a planetary engineering system that can move miles of ice across continents based on sheer orbital mechanics and oceanic inertia. These are the foundational structural factors driving our world's global 'climate' - not CO₂. The Earth's muscles are built on a restless tectonic global framework, floating over a colossal boiling magma ocean. As these plates move over time, the geography and powerful ocean currents all change course. The atmosphere is a distant consequence of landform shifts, ocean dynamics and now biological life. The rise of cellular life and production of oxygen are all entirely biological, based on cyanobacteria, CO₂, sunlight, water and nutrients. But weathering, the demands of new life, eternally shifting landforms and endless storms have reduced CO₂ from levels that were once several thousands parts per million to only around 420 ppm today. This essential component of biological life also creates oxygen and supports every food chain on Earth in a slow but steady dance. Our habitable planet is profoundly shaped by the intermittent anomalies of Earth's orbit, identified by Serbian mathematician Milutin Milanković. Orbital fluctuations dictate the distribution of solar energy - known as insolation. They are eccentricity, axial tilt (obliquity) and precession, the primary drivers of the glacial-interglacial 'yo-yo' effect of the last 2.6 million years (the Quaternary). The cycles provide the 'timing', while things like 'oceanic inertia' provide the magnitude. Earth's ceaselessly shifting biosphere and its storms and weather patterns isn't because of CO₂ - a single atmosphere trace gas - it's structural. It's planetary. The Earth is an oceanic planet. It's a living world of moving landscapes, ocean currents and air, all supporting a thriving global infrastructure of biology. Structure and engineering reshaped the world's blueprint. Amid these myriad threads was the global decline of CO₂ as a component of the atmosphere. The massive uplift of the Tibetan Plateau and the rise of the Himalayas 55 mya were caused by the tectonic impact of the Indian subcontinent. This was chemical weathering in action—silicate rocks reacting with rainwater—which didn't just change wind patterns, it created a geological vacuum. But the climate always changes over time, and always has. Earth's engineering backup system began to readjust to long-term cooling when the Eocene ended (56 to 33.9 million years ago). Tectonic shifts opened up the equatorial waterway Drake Passage 30-35 million years ago, creating the Antarctic Circumpolar Current and thermally isolating the south pole, thus initiating the growth of ice sheets. As it was virtually landlocked anyway, the Arctic followed suit. We are still living in this same ice age scenario. The Antarctica became ice covered 34 million years ago due to parallel events. The closure of the Isthmus of Panama and the drifting of the continents 3 million years ago also interrupted the equatorial 'warm belt' flow. These processes slowed tropical currents reaching the poles, fundamentally altered the ocean's conveyor belt (the Thermohaline Circulation) and reshaped climate. These tectonic shifts didn't just change wind patterns; they activated a weathering process that has been sucking CO₂ out of the atmosphere ever since. What we measure over hundreds of millions of years - since the Cambrian Explosion - is clear and concerning evidence of CO₂ starvation. We must be looking at the wrong end of the telescope by ignoring the biological and structural engineering of a thriving planet.

The Milankovitch cycles have been Earth's heart pacemaker for millions of years. Orbital mechanics have dominated throughout. Cyclical shifts from icy glacial to warm interglacial periods - then back again - are not due to CO₂. They are a direct mechanical consequence of Earth’s positioning in space relative to the sun. The three anomalies, known as the Milankovitch cycles, are 'eccentricity' (orbital shape), 'obliquity' (Earth's tilt), and 'precession' (a planetary wobble). These cycles dictate the distribution of solar insolation flux (sunlight), particularly at 65°N, which acts as the kill switch for ice sheets. Earth is now in the Late Cenozoic Ice Age Glaciation; oddly unnoticed in a crisis about planetary warming. Global cooling is far more significant. An already cooling climate intensified 34 million years ago with the glaciation and geographical isolation of the Antarctic continent. CO₂ is not the driver nor has it initiated the many warm interglacial cycles. Even the previous glacial period, known as the Eemian, was 2 degrees warming on average than today, yet CO₂ did not shift from a steady 295 ppm. If the sheer tilt and wobble of the planet provided the energy to retreat miles of ice, then CO₂ was at best a faint secondary feedback in this process, nothing more.

WARNING: Maltodextrin is sneakier and MORE DANGEROUS than sugar — and it’s hiding in almost EVERY processed food! Glycemic Index: • Sugar: 65 • High Fructose Corn Syrup: 87 • Glucose: 100 • Maltodextrin: 136 🔥 It’s a heavily processed carb (from GMO corn, rice, wheat, potato or tapioca starch) that spikes your blood sugar and insulin harder than sugar — but food companies don’t have to list it as “sugar” or “added sugar” on labels. It hides under names like: • Maltodextrin • Modified Food Starch • Modified Corn Starch • “Natural Flavors” You’ll find it in artificial sweeteners, yogurt, cereals, baked goods, nutrition bars, shakes, sauces, condiments, chips, snacks, low-fat products, and even “sugar-free” items. This stuff destroys the protective lining in your intestines, triggers leaky gut, systemic inflammation, and has been linked to: • Altered gut bacteria • IBD / Crohn’s / Ulcerative Colitis • Diabetes & insulin resistance • Hormonal imbalance • Weight gain • GI distress Front-of-pack “healthy” claims are lying to you. Always flip the package and read the FULL ingredients list. Your body is NOT a trash can. Who else is done being poisoned by hidden fillers?

@BackpirchCrew An impressive storm. The airport weather station at Learmonth AU reported peak sustained wind of 75kt with peak gust to 104kt and lowest pressure 965mb. Peak sustained wind might be 10-minute average, but not sure.

New satellite imagery released by CIMSS shows the ongoing impact of Cyclone Narelle’s massive double-eyewalls on the North West Cape of Australia. With gusts of >120 MPH recently recorded in Learmonth, Narelle is now the strongest storm to hit this desert peninsula in 27 years.

What the Maasai warrior ate: - Beef - Blood, mixed with milk, drunk ceremonially and daily - Full-fat cattle milk - Occasional goat What the Maasai did not eat: - Grains - Vegetables - Processed anything - Seed oils - Supplements What the researchers found when they arrived in the 1960s expecting metabolic catastrophe: - Cholesterol levels well below Western averages - Arteries, in autopsy, that were clean - Essentially zero cardiovascular disease - Essentially zero obesity - Essentially zero type 2 diabetes George Mann ran the studies. He expected to confirm Ancel Keys. He found the opposite. He published the data. The data was ignored. Keys became the most influential nutritionist of the 20th century. Mann called the diet-heart hypothesis "the greatest scam in the history of medicine." The Maasai are still there. Still eating meat and blood and milk. Still fine.
