Killing the Whole Planet

The Amazon is Crashing

Amazon deforestation is close to tipping point,
Fundação de Amparo à Pesquisa do Estado de São Paulo, March 19, 2018.

 FULL CRASH MODE APPROACHING

"Deforestation of the Amazon is about to reach a threshold beyond which the region's tropical rainforest may undergo irreversible changes that transform the landscape into degraded savanna with sparse shrubby plant cover and low biodiversity."

"The Amazon system is close to a tipping point."

OLD TIPPING POINT

"...the tipping point would be reached if approximately 40% of the region were deforested." 

NEW TIPPING POINT

"...climate change and indiscriminate use of fire...indicates a shift to non-forest ecosystems in the eastern, southern and central portions of the Amazon region at between 20% and 25% deforestation."

Amazing Human-Climate Interactions

What a Long, Strange Trips It’s Been

Ancient farmers spared us from glaciers but profoundly changed Earth's climate,
University of Wisconsin-Madison, September 6, 2018.

MAIN POINTS

Human Global Warming began a Long Time Ago
“Millenia ago, ancient farmers...may have been fundamentally altering the climate of the Earth.“

Ice Age Averted
“...without this human influence, by the start of the Industrial Revolution, the planet would have likely been headed for another ice age.”

First Human Tipping Point
“...the Holocene reversed direction 5,000 years ago, hitting peak concentrations of both gases by 1850.”

The Long Cycle
“For most of Earth's 4.5-billion-year history, its climate has largely been determined by a natural phenomenon known as Milankovitch Cycles, periodic changes in the shape of Earth's orbit around the sun - which fluctuates from more circular to more elliptical - and the way Earth wobbles and tilts on its axis.“

Tipping Points Falling Like Dominoes

Nine Climate Tipping Points Now 'Active,' Warn Scientists,
University of Exeter, November 27, 2019.

MAIN POINTS

"More than half of the climate tipping points identified a decade ago are now "active", a group of leading scientists have warned."

"This "cascade" of changes sparked by global warming could threaten the existence of human civilisations."

"...these events are more likely and more interconnected than was previously thought, leading to a possible domino effect."

"...we must admit that we have underestimated the risks of unleashing irreversible changes, where the planet self-amplifies global warming."

Moron Alert
"Scientifically, this provides strong evidence for declaring a state of planetary emergency, to unleash world action that accelerates the path towards a world that can continue evolving on a stable planet."

Easy Money
"Exiting the fossil fuel economy is unlikely before 2050, but with temperature already at 1.1°C above pre-industrial temperature, it is likely Earth will cross the 1.5°C guardrail by 2040."

University of Groningen, December 30, 2019.

MAIN POINTS

Gulf Stream & Its Effects
"The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate."

Big Problems Coming
"...scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current."

"...there is a 15 percent likelihood that there will be a temporary change in the current in the next 100 years."

NEW WORLD WEATHER

Storm Intensity Increased by Climate Change

Study Confirms Climate Change Impacted Hurricane Florence's Precipitation and Size,
Stony Brook University, January 2, 2020.

MAIN POINTS

New Model
"The research in this study, however, is a first to use a "forecast attribution" framework that enables scientists to investigate the effect of climate change on individual storm events days in advance."

Climate-'Enhanced' Forecast
"They predicted Hurricane Florence would be slightly more intense for a longer portion of the forecast period, rainfall amounts over the Carolinas would be increased by 50 percent due to climate change and warmer water temperatures, and the hurricane would be approximately 80 kilometers larger due to the effect of climate change on the large-scale environment around the storm."

New World Storms
"More importantly, this post-storm modeling around climate change illustrates that the impact of climate change on storms is here now and is not something only projected for our future."

Thinning Antarctic Ice Shelf & Ice Sheet's Slippery Relationship

 

OCEANS, ICE, & THE ANTARCTIC

Antarctic Ice Shelf & Ice Sheet's Slippery Relationship

Evidence: Antarctica's Thinning Ice Shelves Causing More Ice to Move from Land into Sea,
Northumbria University, December 2, 2019.

MAIN POINTS

The Theory
Corked & Bottled-Up Ice
"Satellite measurements taken between 1994 and 2017 have detected significant changes in the thickness of the floating ice shelves that surround the Antarctic Ice Sheet. These shelves buttress against the land-based ice, holding them in place like a safety band."

"It is believed that the ice shelves may be thinning due to changes in ocean heat content, either by ocean warming or from changes in how the ocean circulates around and below the shelves..."

Glaciers Uncorked
"There are other processes in play as well, but we can now state firmly that the observed changes in ice-shelves do cause significant changes over the grounded ice, speeding up its flow into the ocean."

Big Changes are Here, & Accelerating

Arctic shifts to a carbon source due to winter soil emissions,
NASA/Goddard Space Flight Center, November 8, 2019.

MAIN POINTS

What is Permafrost
"Permafrost is the carbon-rich frozen soil that covers 24% of Northern Hemisphere land area, encompassing vast stretches of territory across Alaska, Canada, Siberia and Greenland. Permafrost holds more carbon than has ever been released by humans via fossil fuel combustion, and this permafrost has kept carbon safely locked away in an icy embrace for tens of thousands of years. But as global temperatures warm, permafrost is thawing and releasing greenhouse gases to the atmosphere."

Megacity Thieves, Grouse, and Ranchers Fight over Diminishing Waters

Los Angeles reduces Eastern Sierra water deliveries because of climate change. At risk, ranchers say, is a way of life,
LA Times, September 24, 2018.

MAIN POINTS

Ranchers Out
“...LADWP has for seven decades provided several lessees in the area about 5 acre-feet of water per acre per year, which made their pastures nutritious through the summer and added luster to the area’s hiking, biking and angling hotspots. (An acre-foot of water equals about 326,000 gallons, more than enough to supply two households for a year.)”

“...new 20-year leases for 10 longtime ranchers in area, the department says lessees should anticipate that little to no water will be available for them.”

Grouse Lifeline

“...it would continue diverting about 1,000 acre-feet of water per year to protect the estimated 600 sage grouse in the area, a segment of a subspecies only found along the California-Nevada border.
