The world’s oceans play a tremendously important role in the global dynamics of the carbon dioxide (CO2) that is released by the burning of fossil fuels, the clearing of forests, and industrial processes.
Suitable pika habitat is restricted to regions of less than 30 days per year above 95°F. They keep their warm winter coats year-round, and are thus very sensitive to air temperatures above about 75°F. Long exposure to these temperatures kills them outright. The climate warming we have experienced over the last century is already having an effect, particularly in the southern part of their range – New Mexico, Nevada, California and Utah.
Assessing the vulnerability of wildlife to climate change is a key part of the adaptation planning process and helps practitioners design effective adaptation strategies. Vulnerability refers to the degree to which a species or other conservation target (such as a habitat type) is likely to experience harm from a threat such as climate change.
The loss of coral reefs is a complicated phenomenon and involves a host of factors. Pollution from onshore, including sewage effluent, agricultural runoff, and sediments promote the growth of algae that suffocates corals, and pollutants like PCBs, pesticide residues, heavy metals and other chemicals are also damaging to corals.
The effects of climate change are already apparent on wildlife, habitats and the natural resources we depend on. Climate change has caused species extinctions, shifted species ranges towards the poles and up the sides of mountains, and reduced the ranges of other species.
Multiple factors are involved in the proliferation of harmful algal blooms. One key cause is excess fertilization.
The effects of climate change are already being felt by wildlife and natural systems, and even with immediate action to reduce greenhouse gas emissions, these effects will continue for decades to come. Natural resource managers are just coming to grips with what this means for the future of conservation strategies.
Climate change impacts in lynx habitats include rising temperatures and precipitation shifts. These factors will have a direct impact on two critical features of lynx habitat: the presence of boreal forest, and the extent of winter snow cover.
With a mix of temperate and tropical, arid and wetlands, forests, grasslands, and islands, Florida is one of the most biologically rich states in the U.S., with 755 vertebrate species and over 30,000 invertebrate species. Florida boasts an incredible array of plants, wildlife, and unique habitats.
Climate changes are projected to cause considerable stress to the wildlife of the Southwest region and to the habitats upon which they depend.
