However, the speed of recent climate change is very fast. Due to this rapid change, for example cold-blooded animals (a category which includes amphibians, reptiles and all invertebrates) may struggle to find a suitable habitat within 50 km of their current location at the end of this century (for a mid-range scenario of future global warming).

A team of researchers from Mainland China and Hong Kong were able to establish a causal connection between climate change and large-scale human crises in pre-industrial times. Short-term crises may be caused by social problems, but climate change was the ultimate cause of major crises, starting with economic depressions. [30]
Climate change and pollution are also major threats. Warmer temperatures not only force some species to travel farther, but can also lead animals to move at different times of year. That can mean ...
Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely. [220] Overall, it is expected that climate change will result in the extinction of many species. [221]
Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction).
[2] [3] [4] Also Gustav Steinmann saw reducing rain forest due to climate change as an important driver for bipedalism. [5] Osborn thought man probably originated from the forests and flood-plains of southern Asia. [6] Hilzheimer stated it was open landscapes that stimulated development. [7]
Unknown; may include climate changes, massive volcanic eruptions and Humans (largely by human overhunting) [4] [5] [6] Neogene: Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene disruption: 14.5 Ma Climate change due to change of ocean circulation patterns.
Dozens of Extinction Rebellion protesters were detained by police late in the afternoon after ignoring orders to end their blockade. Police said the operation to clear the road was peaceful.
