Global warming is occurring rapidly in Arctic marine and terrestrial ecosystems, including tundra and northern coniferous forests. In such locations, reflective white snow and ice cover are melting quickly and extensively, uncovering darker-colored ocean water, plants, and rocks. In a short essay (100-150 words), explain how this process might represent a positivefeedback loop (see Concept 40.2).

Respuesta :

This positive feedback loop causes a big impact on the local environment and actively raises the temperatures especially in the Arctic regions.

Global warming

Long-term changes in temperature and weather patterns are referred to as climate change. These movements may be natural, but human activities have been the primary driver of climate change since the 1800s, mostly owing to the combustion of fossil fuels (such as coal, oil, and gas), which emit heat-trapping gases.

Global warming is a component of climate change that refers to the long-term rise in global temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, primarily from human activities such as the use of fossil fuels and farming.

Major effects of global warming

More frequent and severe droughts, storms, heat waves, rising sea levels, melting glaciers, and warmer waters can directly hurt animals, destroy their habitats, and devastate people's livelihoods and communities.
