Climate is Changing Faster than Animal Adaptation,

"Birds and other animals cannot adapt fast enough to keep pace with climate change, throwing species survival in doubt."

"Our research focused on birds because complete data on other groups were scarce."

"...reviewed more than 10,000 published climate change studies..."

"We demonstrate that in temperate regions, the rising temperatures are associated with a shift in the timing of biological events to earlier dates."

Already Outrageous Human Population Still Rising -- Nature Crashing Rapidly

88 Percent Decline of Big Freshwater Animals,
Forschungsverbund Berlin, August 8, 2019.


"Freshwater megafauna include all freshwater animals that weigh 30 kilograms or more, such as species of river dolphins, beavers, crocodiles, giant turtles and sturgeons."

1970 to 2012
88% Decline
"From 1970 to 2012, global populations of freshwater megafauna declined by 88 percent - twice the loss of vertebrate populations on land or in the ocean."

Major Decliners
"Large fish species such as sturgeons, salmonids and giant catfishes are particularly threatened: with a 94 percent decline, followed by reptiles with 72 percent."

Elephant Extinction will Raise Carbon Dioxide Levels in Atmosphere,
Saint Louis University, July 24, 2019.


"One of the last remaining megaherbivores, forest elephants shape their environment by serving as seed dispersers and forest bulldozers as they eat over a hundred species of fruit, trample bushes, knock over trees and create trails and clearings. Their ecological impact also affects tree populations and carbon levels in the forest,...with significant implications for climate and conservation policies."

Turtle Troubles

No New Males: Climate Change Threat to Cape Verde Turtles,
University of Exeter, July 11, 2019.


Hot End of Loggerhead Turtles
"...by 2100 - more than 90% of loggerhead nests on the Cape Verde islands could incubate at "lethally high temperatures", killing turtles before they hatch."

Turtle Troubles
"The sex of turtle hatchlings is determined by incubation temperature..."

Low Heat Not Happening…
"Even under a scenario based on low future emissions and warming, by 2100 just 0.14% of hatchlings would be male."

"Under mid and high-emissions scenarios, hatching of male loggerheads could cease entirely."

Nearing the End
"We estimate that 84% of current hatchlings are female, and warmer temperatures will increase this proportion."

Due to humans, extinction risk for 1,700 animal species to increase by 2070,
Yale University, March 4, 2019.


Extinction Targets 1700 Species
Cause: Land Use

“The study shows that under a middle-of-the-road scenario of moderate changes in human land-use about 1,700 species will likely experience marked increases in their extinction risk over the next 50 years: They will lose roughly 30-50% of their present habitat ranges by 2070.
These species of concern include 886 species of amphibians, 436 species of birds, and 376 species of mammals -- all of which are predicted to have a high increase in their risk of extinction.”

Climate change and infertility -- a ticking time bomb?
University of Liverpool, January 31, 2019.


The Death Temperature
“...most of the data on when temperature will prevent species surviving in an area is based on the 'critical thermal limit' or CTL - the temperature at which they collapse, stop moving or die.”

End of Sex Temperature
"There is a risk that we are underestimating the impact of climate change on species survival because we have focused on the temperatures that are lethal to organisms, rather than the temperatures at which organisms can no longer breed."

Global Warming Increases the Risk of an Extinction Domino Effect


Interdependence of Ecosystems Could be Our Ultimate House of Cards

Global warming increases the risk of an extinction domino effect,
European Commission Joint Research Centre, November 28, 2018.

An extinction domino effect is already underway.


“...there are many elusive drivers of species loss that go beyond the direct effects of environmental change (and human activity) which we still struggle to understand.”

“...it is becoming clearer that co-extinctions (the disappearance of consumers following the depletion of their resources) could be a major culprit in the ongoing biodiversity crisis.”

“...predictions that fail to take into account this cascading effect might underestimate extinctions by up to 10 times.”

The Test
“...constructed 2000 "Virtual Earths", which they populated with thousands of plants and animals organized into a global system of inter-connected food-webs.”

Mammals cannot evolve fast enough to escape extinction


Mammalian Collapse Continues

Mammals cannot evolve fast enough to escape current extinction crisis,


"Humans are exterminating animal species so fast that evolution can't keep up; Unless conservation efforts are improved, so many mammal species will die out during the next 50 years that nature will need 3-5 million years to recover, a new study shows..."

Aarhus University, October 15, 2018.


“We humans are exterminating animal and plant species so quickly that nature's built-in defence mechanism, evolution, cannot keep up. An Aarhus-led research team calculated that if current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3-5 million years to recover.”

“There have been five upheavals over the past 450 million years when the environment on our planet has changed so dramatically that the majority of Earth's plant and animal species became extinct.”

“The sixth mass extinction is happening now, but this time the extinctions are not being caused by natural disasters; they are the work of humans. A team of researchers from Aarhus University and the University of Gothenburg has calculated that the extinctions are moving too rapidly for evolution to keep up.”

"A single non-photosynthetic plant specimen preserved in a Japanese natural history museum has been identified as a new species. However, it is highly possible that this species is already extinct."

“This plant was discovered in Kobe, Japan, in 1992, and preserved with its identity unknown. No new specimens were found in follow-up surveys between 1993 and 1999, and the plant’s original habitat was destroyed by land development in 1999.”
