Ocean currents influence climate by transporting warm and cold waters to other regions.

Snowfall and thunderstorms are the two major weather systems that influence the climate throughout the ecoregion.

This result leaves open the possibility that cosmic rays could also influence climate.

Human activities influence climate and related systems through, among other mechanisms, land usage, water management, and earlier and more significant melting of snow cover due to greenhouse effect warming.

For a more complete idea of how a country influences climate change, gases such as methane and nitrous oxide should be taken into account.
