A container ship leaves a trail of white clouds in its wake that can linger in the air for hours. This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution.
New research led by the University of Washington is the first to measure this phenomenon’s effect over years and at a regional scale. Satellite data over a shipping lane in the south Atlantic show that the ships modify clouds to block an additional 2 Watts of solar energy, on average, from reaching each square meter of ocean surface near the shipping lane.
The result implies that globally, cloud changes caused by particles from all forms of industrial pollution block 1 Watt of solar energy per square meter of Earth’s surface, masking almost a third of the present-day warming from greenhouse gases. The open-access study was published March 24 in AGU Advances, a journal of the American Geophysical Union.
The Global Lower Atmosphere plunged 0.28C in March to 0.48C, from its (expected early-year) high of 0.76C in February. Looking at the Sun, the cycles, the past, and the graphs, it is reasonable to assume there’s only one trend from here on out, and that’s down…
Take the previous anomalous “warming spikes” on the UAH Satellite-Based Temperature of the Global Lower Atmosphere chart (below) — they generally occur at the beginning of a year, and then are quickly followed by a sharp downward plunge:
We might be sitting on enough gas to power the world for hundreds, if not thousands, of years.
In a world awash in oil and gas, you’d think it couldn’t get any worse. Well, it can: China just announced that it had extracted a record amount of what has been poetically called fire ice. It is, however, a form of natural gas trapped in frozen water.
Though it’s believed the 130 ppm increase in atmospheric CO2 concentration since 1750 has caused the ocean waters to “acidify”, on a daily basis 50-380°C metallic acid enriched by CO2 concentrations reaching 60,000 to 95,000 ppm pours through seafloor vents. Nearby coral reefs “thrive” in these high-CO2 conditions.
50 times more CO2 in the oceans than in the atmosphere
Though many believe humans are “acidifying” the oceans by burning fossil fuels and emitting CO2, the ability of humans to impact the oceanic CO2 concentration is already compromised by the observation that the ocean waters contain about 50 times more CO2 (38,000 vs. 750 PgC) than the atmosphere does (North et al., 2014).
CATASTROPHIC GLOBAL WARMING IS A FALSE CRISIS – THE NEXT GREAT EXTINCTION WILL BE GLOBAL COOLING
Forget all those falsehoods about scary global warming, deceptions contrived by wolves to stampede the sheep. The next great extinction event will not be global warming, it will be global cooling. Future extinction events are preponderantly cold: a glacial period, medium-size asteroid strike or supervolcano. Humanity barely survived the last glacial period that ended only 11,500 years ago, the blink-of–an-eye in geologic time.
Cold, not heat, is by far the greater killer of humanity. Today, cool and cold weather kills about 20 times as many people as warm and hot weather. Excess Winter Deaths, defined as more deaths in the four winter months than equivalent non-winter months, total over two million souls per year, in both cold and warm climates. Earth is colder-than-optimum for humanity, and currently-observed moderate global warming increases life spans.
“Cold Weather Kills 20 Times As Many People As Hot Weather”

However, Excess Winter Deaths are not the worst threats to humanity. The glacial cycle averages about 100,000 years, consisting of about 90,000 years of the glacial period, when mile-thick continental glaciers blanketed much of the Northern and Southern Hemispheres including Canada, Russia, Northern Europe and Northern USA, and about 10,000 years of interglacial, the warm period of the present. Earth is now 11,500 years into the current warm interglacial, and our planet may re-enter the glacial period at any time.
Today (Monday, March 30) is the 30th anniversary of our publication in Science describing the first satellite-based dataset for climate monitoring.
While much has happened in the last 30 years, I thought it might be interesting for people to know what led up to the dataset’s development, and some of the politics and behind-the-scenes happenings in the early days. What follows is in approximate chronological order, and is admittedly from my own perspective. John Christy might have somewhat different recollections of these events.
Some of what follows might surprise you, some of it is humorous, and I also wanted to give credit to some of the other players. Without their help, influence, and foresight, the satellite temperature dataset might never have been developed.
