When estimating the effect of climate change on species' extinction risk, the report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of the Earth's species with extinction even in the absence of any other factors like land use change. If the warming reached 4.3 °C (7.7 °F), they ...
Data from 2018 found that at 1.5 °C (2.7 °F), 2 °C (3.6 °F) and 3.2 °C (5.8 °F) of global warming, over half of climatically determined geographic range would be lost by 8%, 16%, and 44% of plant species. This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria. [58] [15]
The 2007 IPCC Fourth Assessment Report concluded that over the last three decades human-induced warming had likely had an influence on many biological systems. [25] [26] [27] The Sixth Assessment Report found that half of all species with long-term data had shifted their ranges poleward (or upward for mountain species).
The AP reports that about 54 million years ago mammals, humans' earliest primate ancestor included, "shriveled a bit in size at least twice in Earth's history when temperatures spiked."
The following day (10 May), Jason Samenow wrote in The Washington Post that the spiral graph was "the most compelling global warming visualization ever made", [27] and, likewise, former Climate Central senior science writer Andrew Freedman wrote in Mashable that it was "the most compelling climate change visualization we’ve ever seen". [28]
Even if greenhouse gas emissions are stopped relatively soon, global warming and its effects will last many years. This is due to the inertia of the climate system. So both carbon neutrality ("net zero") and adaptation are necessary. [21] The Global Goal on Adaptation was also established under the Paris Agreement.
Of those, about 3.1 million are dogs and 3.2 million are cats. About 920,000 shelter animals are euthanized yearly, the ASPCA said, a decrease from the estimated 2.6 million cats and dogs ...
The test results revealed that the five dogs made 44% correct choices while attempting to retrieve their old toys from memory, which was higher than the average chance level of 20.4%.
