The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
Local extinctions of approximately 6 species are expected in each 2500 km 2 region by 2050 due to past deforestation. [28] Birds in the Amazon rainforest continued to become extinct locally for 12 years following logging that broke up contiguous forest into smaller fragments. The extinction rate slowed, however, as forest regrew in the spaces ...
Unknown, but may be due to volcanism of the Rajmahal Traps [15] Jurassic: End-Jurassic (Tithonian) 145 Ma: No longer regarded as a major extinction but rather a series of lesser events due to bolide impacts, eruptions of flood basalts, climate change and disruptions to oceanic systems [16] Pliensbachian-Toarcian extinction (Toarcian turnover ...

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".

The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark at high speed.
Orcas in the Gulf of California appear to have gained special skills to hunt and kill the world’s largest fish, according to a new study.. Whale sharks, which grow up to 18m long, are known to ...
