The number of tiger salamanders were decreasing.
decreasing
John Harte observed that salamander populations were declining in the Rocky Mountains due to climate change. Warmer temperatures were leading to drier habitats, causing disruptions in the salamanders' habitats and reducing their numbers.
Harte's hypothesis was that acid rain was falling as winter snow on the Rockies. The acid was released when the snow melted in the spring.
Dr. John Harte hypothesized that melting snow causes acidity in the ponds he was studying. His data indicated that there was a drop in the pH level of the ponds after the snow melted, which proved his hypothesis.
John Harte's data showed the volume-weighted average pH for summer events was 4.61, for winter events was 5.11 and for the entire period was 4.91. Within the watershed, both low- and medium-alkalinity surface waters exist.

John Harte found that snowmelt in the mountains of west central Colorado released high levels of sulfates and other pollutants due to the melting of acidic snow caused by air pollution.
