A feedback that amplifies an initial change is called a positive feedback [12] while a feedback that reduces an initial change is called a negative feedback. [12] Climate change feedbacks are in the context of global warming, so positive feedbacks enhance warming and negative feedbacks diminish it.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
In business analysis, PEST analysis (political, economic, social and technological) is a framework of external macro-environmental factors used in strategic management and market research. PEST analysis was developed in 1967 by Francis Aguilar as an environmental scanning framework for businesses to understand the external conditions and ...
The claim: Climate change has only had 'positive effects' on global food production. An Oct. 20 Facebook post (direct link, archive link) includes a graph that shows global wheat, rice and coarse ...
They are usually depicted as unwanted and negative, based on the concept that any change in the environment caused by human activities is damaging and degrading. [3] Pressures can have effects on the short run (e.g.: deforestation), or the long run (e.g.: climate change), which if known with sufficient certainty, can be expressed as a probability.
A 2020 meta-analysis found that while 39% of vascular plant species were likely threatened with extinction, only 4.1% of this figure could be attributed to climate change, with land use change activities predominating. However, the researchers suggested that this may be more representative of the slower pace of research on effects of climate ...
Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. [299] It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. [300]
Climate change and the associated changing weather patterns occurring worldwide have a direct effect on biology, population ecology, and the population of eruptive insects, such as the mountain pine beetle. This is because temperature is a factor which determines insect development and population success. [87]
