Editor’s Note – Outside the Media Spotlight

Stephan:  The media is completely consumed by the madman in the White House and the Coronavirus. For weeks now there has been only this one story. But just because the media spotlight is not on something does not mean it isn't happening. In fact, there are changes coming that will be every bit as dramatic and consuming as Covid-19. Here are some of the trends that I am following that are going to affect your life Remember: there is no click through to Editor Notes.

The projected timing of abrupt ecological disruption from climate change

Stephan:  Schwartz' Law of Climate Change: Whatever is predicted will be worse than predicted and will happen more quickly than predicted. What follows is a very important research report, and I urge you to click through and read it; what it describes will certainly affect your personal life. The headline: If humans cannot overcome their stupidity and greed and focus instead on fostering wellbeing, starting in the next decade sudden and rapid collapse of ecosystems will occur and forever change the world. How are you with that?

As anthropogenic climate change continues the risks to biodiversity will increase over time, with future projections indicating that a potentially catastrophic loss of global biodiversity is on the horizon1–3. However, our understanding of when and how abruptly this climate-driven disruption of biodiversity will occur is limited because biodiversity forecasts typically focus on individual snapshots of the future. Here we use annual projections (from 1850 to 2100) of temperature and precipitation across the ranges of more than 30,000 marine and terrestrial species to estimate the timing of their exposure to potentially dangerous climate conditions. We project that future disruption of ecological assemblages as a result of climate change will be abrupt, because within any given ecological assemblage the exposure of most species to climate conditions beyond their realized niche limits occurs almost simultaneously. Under a high-emissions scenario (representative concentration pathway (RCP)8.5), such abrupt exposure events begin before 2030 in tropical oceans and spread to tropical forests and higher latitudes […]

Great Barrier Reef suffers its most widespread mass bleaching event on record

Stephan:  Here is a follow up on the report I ran earlier this year about the collapse of the Great Barrier Reef in Australia. It proves Schwartz' Law of Climate Change once again. If you think Covid-19 has changed your life; nature is just getting started.

Earlier this year, scientists warned that the Great Barrier Reef could be on the brink of its most widespread bleaching event ever recorded. That fear has been realized.

Surveys conducted by scientists at Australia’s James Cook University and the Great Barrier Reef Marine Park Authority show that a summer of extreme heat has caused the reef, which is a World Heritage Site, to suffer a mass bleaching of unprecedented scale. Corals from the far north to the southern tip of the 1,400 mile-long ecosystem are experiencing severe impacts.

It was also one of the reef’s worst mass bleaching episodes in terms of intensity, second only to 2016, which killed half of all shallow-water corals on the northern Great Barrier Reef.

Unlike the summer of 2016, when an intense marine heat wave coincided with one of the strongest El Niño events on record, this past summer brought a bleaching […]

Record Shrinking of Greenland’s Ice Sheet Raises Sea Levels

Stephan:  Here's another follow-up, this one about Greenland's ice. Another confirmation of SLCC. Just because the media doesn't cover something doesn't mean it isn't happening. We are very quickly reaching the decision crisis point. America's fate will be determined by how the 2020 election comes out.

Greenland’s kilometers-long ice sheet underwent near-record imbalance last year, scientists have reported on Wednesday.

The ice sheet suffered a net loss of 600 billion tons, which was enough to raise the global watermark 1.5 millimeters, accounting for approximately 40% of total sea-level rise in 2019.

The alarming development was reported in “The Cryosphere,” a peer-reviewed journal published by the European Geosciences Union.

Researchers noted that the massive melt was not due only to warm temperatures but also to unusual high-pressure weather systems, which suggested that scientists may be underestimating the threats the ice faces.

The unusual high-pressure weather systems are linked to climate change and they have blocked the formation of clouds, causing unfiltered sunlight to melt the surface of the ice sheet.

Fewer clouds also meant less snow, which researchers found to be some 100 billion tons below the 1980-1999 average.

“These atmospheric conditions are becoming more and more […]

Rising Sea Levels Could Double Extreme Flooding Events on Coastline, Report States

Stephan:  No one in business pays closer and more accurate attention to climate change than the insurance industry. This is what they are talking about. I urge you again to click through and read the report. Paying close attention to what climate change is doing is going to become very important for planning a life of wellbeing.

Sea-level rise will radically redefine the coastline of the 21st century.”

That’s from a new study that shows rising sea levels could lead to extreme flooding events in some U.S. coastal areas doubling every five years.

The study published on Thursday in Scientific Reports suggests that extreme water levels that are now reached once every 50 years may be exceeded daily along U.S. coastlines before the end of the 21st century.

“We find that the odds of exceeding critical water-level thresholds increases exponentially with sea-level rise, meaning that fixed amounts of sea-level rise of only 1–10 cm in areas with a narrow range of present-day extreme water levels can double the odds of flooding,” the report states. “Combining these growth rates with established sea-level rise projections, we find that the odds of extreme flooding double approximately every five years into the future.”

Scientists from the U.S. Geological Survey, the University of Hawaii and the University of Illinois looked at the continuous shift in coastal flooding scenarios using tide gauges combined with data from sea-level rise scenarios to model the rate at which flooding events may […]
