Climate Change
Freshwater wetlands provide critical habitat for a diverse array of organisms including many amphibians. Yet, under the continued impacts of water diversions and the newer threats of climate change, these habitats are among the most imperiled ecosystems on Earth. Climate change has the potential to alter many sources of water critical to the habitats amphibians need, especially those associated with breeding and development. Potential changes include: change in timing and availability of water from glacier melt, snow and rain timing and amount; persistence of vernal pools and seasonal wetlands; altered evapotranspiration rates; and reduced stream flows and groundwater recharge rates.
Other ecosystem components likely to change in response to climate change include the timing and frequency of fires, the spread of invasive plants and animals, and microclimates in which the animals live.

Data Release Calculations of BioLake climate data
These BioLake raster data provide global estimates (~10.0 x 12.4 km resolution) of twelve bioclimatic variables based on estimated lake temperature. Eleven of these twelve variables (BioLake01 - BioLake11) are estimated for each of three lake strata: lake mix (surface) layer, lake bottom, and total lake water column. These eleven variables correspond to CHELSA (Climatologies at high resolution for the earth's land surface areas) bioclimatic variables BIO1 - BIO11, except that these BioLake variables are based on lake water temperature and CHELSA BIO1 - BIO11 variables are based on air temperature. CHELSA BIO is also calculated a finer spatial resolution (~1 x 1 km). The twelfth variable (BioLake20; months with non-zero ice cover) does not correspond to any CHELSA bioclimatic variable. The data are supplied as a multi-layer raster (.grd) file in the World Mollweide projection, accompanied by a header file (.gri) with layer names.
