Switch to Renewable Energy


Storm Coming (NASA)

GR–Ode to concerned scientists: They see the danger, they sound the horns and clang the bells, and they wait. But the ramparts remain empty. They turn to their family and friends, but dreamlike their voices are too soft and none respond.

“Fifteen thousand scientists have issued a dire warning to humanity about impending collapse but virtually no-one takes notice. Ultimately, our global systems, which are designed for perpetual growth, need to be fundamentally restructured to avoid the worst-case outcome.

“For a moment, the most important news in the entire world flashed across the media like a shooting star in the night sky. Then it was gone. In November, over fifteen thousand scientists from 184 countries issued a dire warning to humanity. Because of our overconsumption of the world’s resources, they declared, we are facing “widespread misery and catastrophic biodiversity loss.” They warned that time is running out: “Soon it will be too late to shift course away from our failing trajectory.”

“This is not the first such notice. Twenty-five years ago, in 1992, 1,700 scientists (including the majority of living Nobel laureates) sent a similarly worded warning to governmental leaders around the world. In ringing tones, they called for a recognition of the earth’s fragility and a new ethic arising from the realization that “we all have but one lifeboat.”

“This second warning contains a series of charts showing how utterly the world’s leaders ignored what they were told twenty-five years earlier. Whether it’s CO2 emissions, temperature change, ocean dead zones, freshwater resources, vertebrate species, or total forest cover, the grim charts virtually all point in the same dismal direction, indicating continued momentum toward doomsday. The chart for marine catch shows something even scarier: in 1996, the catch peaked at 130 million tonnes and in spite of massively increased industrial fishing, it’s been declining ever since—a harbinger of the kind of overshoot that unsustainable exploitation threatens across the board.” –Jeremy Lent (What Will It Really Take to Avoid Collapse?).

How Many of You Switched to Renewable Energy?

In recent posts, I described the warnings of impending disaster. I didn’t expect to have an impact, and I wasn’t wrong. As Jeremy Lint points out in the article above, the media avoidance of unappetizing topics is too complete. And of course, our leaders in power avoid the subject in their subservience to wealth. My first hint that good advice for avoiding collapse would be futile was the minimal response to my discovery of the simple and inexpensive means for everyone to switch their homes from fossil fuel energy to renewable energy. Like Pangloss, I’ve remained hopeful. But I read that book, and now I’ve turned to a more practical concern; the post-anthropocene survivors, the weeds, have absorbed my attention. Today’s weed is Shepherdspurse, a foreign but familiar little mustard that feeds butterflies and yields medicines for us humans.

How a Warming Planet Drives Human Migration

GR:  Thoughts on Climate Change

The climate news today (and really every day now) is not good. The Times article below focuses on just one of the bad bits. Global warming and consequent shifts in weather patterns are stressing everyone, but especially those people living in equatorial regions. Droughts, fires, and floods are becoming intolerable. The emerging climate-change-driven diaspora will carry the stress north and south into temperate latitudes. Projections made by many scientists in the U. S., European Union, and Asia portray a dismal future for Earth and humanity.

A Glimpse of Future Earth

Climate-change emigrants and their descendents moving north will not escape the ravages of a warming planet for very long. Stresses in northern latitudes have already begun. As the human population squeezes north to find food and water, resources will dwindle and conflicts will intensify. Nature in even the diminished form that we see now will sink toward unsustainable levels where wild plants and animals, then watersheds, then soils, and then fresh water are lost.

As I look out across my fields of invasive weeds and my ponds and small stream choked with artificially fertilized algae and filled with invasive animals, I remember the sunflowered fields and sparkling creek of my childhood. As the pace of climate change accelerates, “the good old days” will become a meaningful phrase for younger and younger people facing a constant need to adapt to more difficult times.

“Climate change is not equal across the globe, and neither are its longer term consequences. This map overlays human turmoil — represented here by United Nations data on nearly 64 million “persons of concern,” whose numbers have tripled since 2005 — with climate turmoil, represented by data from NASA’s Common Sense Climate Index. The correlation is striking. Climate change is a threat multiplier: It contributes to economic and political instability and also worsens the effects. It propels sudden-onset disasters like floods and storms and slow-onset disasters like drought and desertification; those disasters contribute to failed crops, famine and overcrowded urban centers; those crises inflame political unrest and worsen the impacts of war, which leads to even more displacement. There is no internationally recognized legal definition for “environmental migrants” or “climate refugees,” so there is no formal reckoning of how many have left their homes because climate change has made their lives or livelihoods untenable. In a 2010 Gallup World Poll, though, about 12 percent of respondents — representing a total of 500 million adults — said severe environmental problems would require them to move within the next five years.

  1. ‘Amazon Basin: As glacial melting reduces freshwater reserves for the Andean plain, tensions are growing between locals and the mining and agribusiness operations that consume much of what remains. Researchers predict that this resource conflict will drive more migrants to the Amazon Basin where many have already turned to informal mining and coca cultivation, fueling the rise of criminal syndicates.

2017’s Warming Climate Produces Unprecedented Floods Across the Globe

GR: More CO2, more warming, more evaporation, and more extreme storms.

“A robust result, consistent across climate model projections, is that higher precipitation extremes in warmer climates are very likely to occur.” — IPCC

“As the climate has warmed… heat waves are longer and hotter. Heavy rains and flooding are more frequent. In a wide swing between extremes, drought, too, is more intense and more widespread.” — Climate Communications

“It’s a tough fact to get one’s head around. But a warming climate means that many regions will both experience more extreme droughts and more extreme floods. The cause for this new weather severity is that a warming planet produces higher rates of evaporation together with more intense atmospheric convection. Warmer air over land means that the moisture gets baked out of terrain, lakes and rivers faster. And this warming effect causes droughts to settle in more rapidly, to become more intense than we are used to, and to often last for longer periods.

“On the flip side of this severe weather coin, more moisture evaporating from the world’s lands and oceans means that the atmosphere contains a greater volume of moisture overall. This heavier moisture load enters a hotter, thicker, taller lower atmosphere (troposphere). One that is becoming increasingly stingy about giving up that moisture in the form of precipitation much of the time. All that heat and added convective energy just serves as a big moisture trap. So the load of moisture has to be heavier, overall, to fall out. When the atmospheric moisture hoarding finally relents, it does so with a vengeance. Thicker clouds with higher tops drench lands and seas with heavier volumes of rain and snow. And when the rain does fall from these larger storms, it tends to come, more and more often, in torrents.

“California Record Drought to Record Flood in Just 4 Years

“A set of facts that were drawn into stark relief recently in California which over the past few years experienced one of its driest periods on record but, in 2017, is on tap to see its wettest year ever recorded for broad regions. In a section of hard-hit Northern California, the cumulative 2017 rainfall average had, as of yesterday (April 9), hit 87.5 inches. The record for the region in all of the past 122 years is 88.5 inches for the entire year.

“It is just early April. But the region tends to receive most of its moisture from January through March. However, all it would take is a relatively minor storm system to tip the scales into record territory. And it now appears likely that this region will see in excess of 90 inches for the present year.

“Infrastructure damage from this year’s flood for the state is likely to considerably exceed $1 billion. Damage to roads alone is nearly $700 million. And that does not include stresses to dams — like the one at Lake Oroville where an eroded spillway threatened structural integrity and forced 200,000 people to evacuate. Overall, the cost of the repairs combined with the cost of hardening California’s infrastructure to these new extreme weather events could top $50 billion.” –RobertScribbler (Continue reading: 2017’s Warming Climate Produces Unprecedented Floods Across the Globe | robertscribbler.)

For Colombia, The Rain Bombs of Climate Change Fell in the Dark of Night

GR:  More from Robert Scribbler on the intense storms of global warming.

As the lower atmosphere becomes warmer, evaporation rates will increase, resulting in an increase in the amount of moisture circulating throughout the troposphere (lower atmosphere). An observed consequence of higher water vapor concentrations is the increased frequency of intense precipitation events… NASA’s Earth Observatory

“Just off the coasts of Colombia, Ecuador and Peru, the Pacific Ocean has been abnormally warm of-late. For the past month, sea surface temperatures have ranged between 3 and 5 degrees Celsius above average. This excess heating of the ocean surface, facilitated by human-forced climate change, has pumped a prodigious volume of moisture into the atmosphere of this coastal region. Southerly winds running along the western edge of South America have drawn this moisture north and eastward — feeding into the prevailing storms that originate on the Atlantic side of South America and track eastwards.

Sea surface temperature anomaly map from Earth Nullschool shows 4 degree Celsius above average ocean surfaces just off-shore of Ecuadore and Colombia. These extremely warm waters have helped to fuel very severe storms over Peru and Colombia during recent weeks. Such warm ocean waters are not normal and their highest peak temperatures are being increased by a human-forced warming of the Earth, primarily through fossil fuel burning. Image source: Earth Nullschool.

“Lately, these systems have blown up to enormous size as they’ve run across the Andes or collided with pop-up storms along the coast. And the amount of rainfall coming out of the resulting monster thunderstorms has been devastating. In Peru, hundreds of thousands of people have been rendered homeless by these deluges which have caused the tragic loss of 100 souls, destroyed thousands of buildings, 200 bridges, and 2,000 miles of highway. For the state, the estimated damage toll from this ongoing climate disaster is now 6 billion dollars.

“Friday night, a member of this new breed of monster thunderstorms, pumped to greater intensity by the moisture bleed off the record warm ocean waters, unloaded a total of a half-month’s worth of rainfall in just a few hours upon the small Colombian city of Mocoa. More than five inches fell in 1-2 hours on a region where three rivers run out of the mountains toward this community of 40,000. The deluge arrived in the darkness. Its ferocious intensity unleashed a massive flood of boulders, mud, and water as the combined rivers leapt their banks and invaded the town. A nearby hillside, unable to retain integrity beneath this merciless assault of the elements, gave way — burying a large section of Macoa in rubble.” –Robert Scribbler (Continue: For Colombia, The Rain Bombs of Climate Change Fell in the Dark of Night | robertscribbler.)
