The dates derived have been interpreted as suggesting that the main mechanism for extinction was human burning of a landscape that was then much less fire-adapted; oxygen and carbon isotopes of teeth indicate sudden, drastic, non-climate-related changes in vegetation and in the diet of surviving marsupial species.
Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the effects of climate change in Australia. [8] Rainfall in southwestern Australia has decreased by 10–20% since the 1970s, while southeastern Australia has also experienced a moderate decline since the 1990s. [5]

Climate change has been a critical issue in Australia since the beginning of the 21st century. Australia is becoming hotter and more prone to extreme heat, bushfires, droughts, floods, and longer fire seasons because of climate change. Climate issues include wildfires, heatwaves, cyclones, rising sea levels, and erosion. [20] [21] [22] [23]
Kaiho's follow-up paper estimated that under what he considered the most likely scenario of climate change, with 3 °C (5.4 °F) of warming by 2100 and 3.8 °C (6.8 °F) by 2500 (based on the average of Representative Concentration Pathways 4.5 and 6.0), would result in 8% marine species extinctions, 16–20% terrestrial animal species ...
Humans arrived in Australia between 80,000 and 45,000 years ago, living alongside megafauna for 20,000–25,000 years [8] [9] [10] before the megafaunal extinctions that were likely caused by, or partly contributed to by, late Pleistocene climate change; [11] [12] however, the full reason for the extinctions is still unclear and human hunting ...
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
The red kangaroo is the largest extant macropod and is one of Australia's heraldic animals, appearing with the emu on the coat of arms of Australia. [1]The fauna of Australia consists of a large variety of animals; some 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent are endemic to it.
