Anthropocene Joyride

The Anthropocene geological epoch began when human activity first had a GLOBAL impact on the planet’s environments. That was in late 1965, when the first evidence of a human-caused effect was detected EVERYWHERE, indicating a simultaneous global impact by human activity.

That evidence was the signature of radioactivity (Carbon-14) from nuclear bomb test fallout incorporated into tree rings for the year 1965 (within October to December) at all latitudes and longitudes. Atmospheric nuclear bomb explosions were set off from 1945 to, primarily, 1963. The peak of such activity was an orgy of bomb tests by the U.S. and USSR in 1962.

Such a necessary transformation of organized human society is most definitely a challenge to the political processes of Earth’s 193-odd nations, and to the ambitions and prejudices of their political classes, their wealth elites, and their general populations. The practical problem facing climate stabilization activists is to overcome these political difficulties as soon as possible. Admittedly, this is a monumental task, and some fear it impossible. Even so, defeatism here is ignominious while engagement in this cause will at a minimum salvage personal honor, and most optimistically secure humanity’s long-term future.

So for now it is best to think of humans as in the driver’s seat of the Anthropocene Earth Car with the foot mashed down on the gas pedal connected to a powerful fuel-injected engine, but with the brake lines cut. Time of impact is unknown, but terminal speed will be high.

London flooding poses ‘significant risk’ unless immediate action taken | UK news | The Guardian

There is now a significant risk of people drowning in London as the threat of major flash floods increases in the city because of climate change. According to a report by a London Councils taskforce published this month, the danger is particularly severe because there is no overall plan or authority to tackle the increasing threat of flooding in the city.

...

The danger facing the city is highlighted as the Intergovernmental Panel on Climate Change (IPCC) scientists prepare the final draft of a report outlining how nations must adapt to avoid the worst consequences of changes in storm frequencies and weather patterns that will occur in coming years.

Last month the government published its third five-yearly assessment of the risks that Britain faces from the changing climate, and painted a future of drastic disruption and costly impacts. It indicated that the climate crisis was likely to wipe at least 1% a year off the UK’s economy by 2045 if global temperatures were allowed to rise by 2C (3.6F).

Direct radiative effects of airborne microplastics | Nature

the radiative effects of airborne microplastics and associated implications for global climate are unknown. Here we present calculations of the optical properties and direct radiative effects of airborne microplastics (excluding aerosol–cloud interactions). The ERF of airborne microplastics is computed to be 0.044 ± 0.399 milliwatts per square metre in the present-day atmosphere assuming a uniform surface concentration of 1 microplastic particle per cubic metre and a vertical distribution up to 10 kilometres altitude. However, there are large uncertainties in the geographical and vertical distribution of microplastics. Assuming that they are confined to the boundary layer, shortwave effects dominate and the microplastic ERF is approximately −0.746 ± 0.553 milliwatts per square metre. Compared with the total ERF due to aerosol–radiation interactions27 (−0.71 to −0.14 watts per square metre), the microplastic ERF is small. However, plastic production has increased rapidly over the past 70 years28; without serious attempts to overhaul plastic production and waste-management practices, the abundance and ERF of airborne microplastics will continue to increase.

Towards a rigorous understanding of societal responses to climate change | Nature
https://www.nature.com/articles/s41586-021-03190-2

A large scholarship currently holds that before the onset of anthropogenic global warming, natural climatic changes long provoked subsistence crises and, occasionally, civilizational collapses among human societies. This scholarship, which we term the ‘history of climate and society’ (HCS), is pursued by researchers from a wide range of disciplines, including archaeologists, economists, geneticists, geographers, historians, linguists and palaeoclimatologists. We argue that, despite the wide interest in HCS, the field suffers from numerous biases, and often does not account for the local effects and spatiotemporal heterogeneity of past climate changes or the challenges of interpreting historical sources. Here we propose an interdisciplinary framework for uncovering climate–society interactions that emphasizes the mechanics by which climate change has influenced human history, and the uncertainties inherent in discerning that influence across different spatiotemporal scales. Although we acknowledge that climate change has sometimes had destructive effects on past societies, the application of our framework to numerous case studies uncovers five pathways by which populations survived—and often thrived—in the face of climatic pressures
