Water This question can be a good springboard for further exploration of how scientists study and report evidence of climate change. Polar bears are spending more time on land as Arctic ice diminishes, causing them to lose body weight and decline in numbers as they are unable to hunt for favored prey such as seals. Using field observations and remote sensing, the study showed that polar bears are spending more time on land and are fasting for longer periods of time. Perhaps the most visible casualty of climate change, polar bears could be all but extinct by 2100. In a new study published in Ecological Applications, Laidre and her colleagues described how declining sea ice concentrations are affecting the behavior, health, and reproductive success of polar bears. Considering that human activity has indirectly brought together species through planetary warming and increased fossil fuel emissions, the question on the minds of many biologists like Arnold is whether humans should play a role in preventing hybridization like this.
