5/ These winds from the east are projected to keep weakening around the Antarctic margins as a result of climate change. This means that as the climate changes, more warm water could come onto the shelf and cause more ice to melt, which could raise sea levels around the world.

Carbon dioxide (CO₂) averaged about 425 ppm in October 2025

10 years ago October averaged about 398 ppm

Data available at gml.noaa.gov/ccgg/trends/
Red line graph time series of monthly carbon dioxide abundance from January 1959 through October 2025. There is a seasonal cycle and long-term increasing trend. Current levels of CO2 are at 425 ppm. This is the Keeling Curve graph. A line for CO2 10 years ago is also annotated.

62 wolves have been killed in Montana since hunting season opened. Killing wolves is neither supported by science nor ethics, yet it becomes a reality when wolves lose federal ESA protections.

As the numbers climb, how many more wolves will be lost without reason?

Marine CO₂ removal lacks standardized indicators to quantify carbon removed and environmental impacts. This absence of reliable metrics prevents verification, inhibits investment, and blocks entry into carbon trading systems.

iopscience.iop.org/article/10.1...
a schematic diagram showing various processes and related indicators for monitoring carbon removal in ocean systems, based on analyzed literature. The diagram divides the processes into three categories represented by different colors: Blue Carbon (green): Focuses on processes related to carbon sequestration and the role of marine ecosystems in capturing and storing carbon. Artificial Upwelling (yellow): Depicts processes that involve artificial interventions in marine environments to increase carbon capture. Ocean Alkalinity Enhancement (blue): Illustrates methods that increase ocean alkalinity, which can help enhance carbon removal. The processes depicted in the diagram include: Carbon Sequestration Potential: This refers to the ability of oceans to capture and store carbon, with an indicator for monitoring this potential. Mineral Dissolution and Seawater Alkalinity Change: These processes are associated with changes in seawater chemistry, enhancing carbon sequestration through increased alkalinity. GHG Emissions: This represents the release of greenhouse gases, which can be measured to monitor the net carbon dynamics in the system. Carbon Removal Rates and Respiration: Shows how carbon is removed from the atmosphere and the role of respiration in this process, measured through carbon flux indicators. Primary Production and Water Masses Detection: This includes the detection of primary production (e.g., photosynthesis) in marine systems that leads to organic carbon formation. Sinking, Remineralization, and Burial: These processes involve the movement of carbon from the surface to deeper ocean layers, with some carbon remineralized and some buried in sediments. 🧪🌊

So what is a #Supermoon? Well, the Moon is typically ~¼ million miles away (30 Earths in a row), but thanks to its elliptical orbit, that distance changes. Tonight the Full Moon is 2-Earths closer than normal (221,823 miles away), making it appear ~15% brighter than usual hence #Supermoon! 🔭🧪

If you've got clear skies, go outside and wave at our neighbour who is looking particularly stunning tonight. And if you have them, root out the binoculars to get a closer look at the grey maria: ~3.5 billion years ago these were seas of molten lava 🤓 #supermoon 🔭🧪

Wow. I did not know that Alfred Russell Wallace (co-discoverer of evolution by natural selection) wrote a book in 1904 about the biological potential for life on other planets, and I've just found this extraordinary paragraph setting out the insanity of atmospheric pollution [1/3]. In 1904!
But the sketch I have here attempted to give of its varied functions shows us that it is really a most complex structure, a wonderful piece of machinery, as[ 259] it were, which in its various component gases, its actions and reactions upon the water and the land, its production of electrical discharges, and its furnishing the elements from which the whole fabric of organic life is composed and perpetually renewed, may be truly considered to be the very source and foundation of life itself. This is seen, not only in the fact of our absolute dependence upon it every minute of our lives, but in the terrible effects produced by even a slight degree of impurity in this vital element. Yet it is among those nations that claim to be the most civilised, those that profess to be guided by a knowledge of the laws of nature, those that most glory in the advance of science, that we find the greatest apathy, the greatest recklessness, in continually rendering impure this all-important necessary of life, to such a degree that the health of the larger portion of their populations is injured and their vitality lowered, by conditions which compel them to breathe more or less foul and impure air for the greater part of their lives. The huge and ever-increasing cities, the vast manufacturing towns belching forth smoke and poisonous gases, with the crowded dwellings, where millions are forced to live under the most terrible insanitary conditions, are the witnesses to this criminal apathy, this incredible recklessness and inhumanity.
