Climate models simulated this trend in 2002. [8] The September minimum ice extent trend for 1979–2011 declined by 12.0% per decade during 32 years. [ 9 ] In 2007, the minimum extent fell by more than a million square kilometers, the biggest decline since accurate satellite data has been available, to 4,140,000 km 2 (1,600,000 sq mi).
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
The Parallel Ice Sheet Model is an open-sourced 3D ice sheet model capable of high resolution. [26] PISM is written in C++ and Python, and takes NetCDF files as input for the model. [ 27 ] PISM uses a "SIA+SSA hybrid" model, using both the shallow shelf approximation and shallow ice approximation models as stress balance models and does not ...
[10] [11] Shipping is more often possible in the Arctic now, and will likely increase further. Both the disappearance of sea ice and the resulting possibility of more human activity in the Arctic Ocean pose a risk to local wildlife such as polar bears. One important aspect in understanding sea ice decline is the Arctic dipole anomaly. This ...
Called the "I Turn Polar Bears White" riddle, it presents a series of cryptic statements that don't seem to make sense at first glance. Take a closer look at this perplexing puzzle and see if you ...
A 2018 paper estimated that if global warming was limited to 2 °C (3.6 °F), gradual permafrost thaw would add around 0.09 °C (0.16 °F) to global temperatures by 2100, [116] while a 2022 review concluded that every 1 °C (1.8 °F) of global warming would cause 0.04 °C (0.072 °F) and 0.11 °C (0.20 °F) from abrupt thaw by the year 2100 and ...
