Time for Planet Citizen Climate Action, Time to Act to Make a Positive Difference
Steve Schmidt / Facebook post, February 10, 2023
GreenPolicy360 Siterunner: News from NOAA today. This is type of work I've been focusing on... #EarthScience ... since the launch of #EarthDay in 1970. I'm remembering George Brown explaining to Gaylord Nelson in a planning mtg how we needed data, climate info w a baseline and access to the data sets for scientists, educators, and public. Rep Brown told the Senator that he'd get the job going in his com't oversight role. He did -- for three decades George shepherded NASA/NOAA/USGS/JPL, a flock of Earth Science missions, programs and their funding. George was referred to over the years as the 'Big Science' man ...

31 Vital Earth Signs
'Virtual signs' worsening
Tipping points, deepening disaster
Researchers, part of a group of more than 14,000 scientists who have signed on to an initiative declaring a worldwide climate emergency, said that governments had consistently failed to address the root cause of climate change: "the overexploitation of the Earth".
Of 31 "vital signs"—key metrics of planetary health that include greenhouse gas emissions, glacier thickness, sea-ice extent and deforestation—they found that 18 hit record highs or lows.

Climate Change: The Face, the Evidence
• https://climate.nasa.gov/evidence/
The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
Scientific evidence for warming of the climate system is unequivocal
- Intergovernmental Panel on Climate Change
The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.
Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.
The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.
Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.

Measuring and Monitoring
"We don't know a planet like this." That was the reaction of meteorologist Eric Holthaus to news that atmospheric carbon dioxide levels have reached heights not seen in the entirety of human existence -- not history, existence.
According to data from the Mauna Loa Observatory in Hawaii, the concentration of CO2 in the atmosphere is over 415 parts per million (ppm), far higher than at any point in the last 800,000 years, since before the evolution of homo sapiens.
