Climate Change and It

Climate change is having adverse impacts on biodiversity in the United States. The National Climate Assessment is a key report that summarizes current and projected climate change impacts on various sectors and regions every four years. The most recent assessment examines impacts on biodiversity, ecosystems, and ecosystem services. It analyzes topics at multiple scales, from individual organisms and species up to ecosystem properties and services that support human well-being. Climate change is affecting different ecosystems in ways that can also impact people, including vulnerable communities.

Climate change and it’s adverse impact on the biodiversity of our country

Periodic assessments of current and future climate change impacts on ecosystems are important for developing
and updating natural resource management plans and evaluating adaption actions (West et al) The National
Climate Assessment (NCA) is a key Assessment in the united states, required by the Global Change Research act to
summarize current and projected impacts on Climate Change on a variety of sectors and regions in the US every
four years (USGCRP, 2018) . Here, we draw upon the recently published Fourth NCA (NCA 4) volume II to present
the most up – to – date assessment of climate change impacts on biodiversity , ecosystems and ecosystem services
in the US (USGCRP, 2018) . We synthesize ,extend , and integrate the NCA 4 chapters focused on natural
resources: Ecosystem, Ecosystem services, and Biodiversity “ (Ch 6) Oceans and Marine Resources (CH 9) : “ Costal
Effects (CH 8) and “ Tribes & Indigenous peoples (Ch15) (USGCRP, 2018) , We provide a more in depth , technical
analysis of topics of interest to scientist and review climate change impact at multiple scales, including ;1) the
individual organism, populations , and species of biodiversity which comprise ecosystems : 2) the properties and
processes that characterize ecosystems: and 3) the good and services that ecosystems provide which support
human economics and well –being (Fig 1) , Further, we explore natural resources and deserve a review of their
own. However, by covering multiple scales in one place , we provide a holistic overview of how climate change is
affecting different ecosystems and how these changes may in turn affect human well – being , including impacts to
vulnerable communities , tribes, and Indigenous peoples.

Generally regarding as a primary mechanism by which species can effectively


adapt to climate change, shift should be considered in the context of entire
ecosystems; an adaptive shift for one species may negatively impact recipient
communities (Wallingford et al, in review)

Examples of the climate – driven changes to ecosystems.
