The IPCC's five reasons for concern are: threats to endangered species and unique systems, damages from extreme climate events, effects that fall most heavily on developing countries and the poor within countries, global aggregate impacts (i.e., various measurements of total social, economic and ecological impacts), [2] [3] and large-scale high ...
Psychological isolation and compartmentalization – Events of everyday life usually lack an obvious connection to global warming. As such, people compartmentalize their awareness of global warming as abstract knowledge without taking any practical action. Hoexter identifies isolation/compartmentalization as the most common facet of soft denial.
Avoiding this future warming will require a large and rapid reduction in global greenhouse gas emissions. The ongoing warming will increase risks and stresses to human societies, economies, ecosystems, and wildlife through the 21st century and beyond, making it imperative that society respond to a changing climate.
The IPCC's Fourth Assessment Report in 2007 asserted that climate change is primarily caused by human activities, marking a pivotal moment in climate advocacy. The Paris Agreement, adopted in 2015 by 196 countries, aimed to limit global warming to well below 2 degrees Celsius, representing a unified global commitment to address climate change.
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity).
As global climate has changed progressively over the past several decades, it has collided with environmental racism.The overlap of these two phenomena, has disproportionately affected different communities and populations throughout the world due to disparities in socio-economic status.
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes.

According to a 2015 journal article based on a literature review of thousands of articles related to over two hundred studies covering the period from 1980 to 2014, there was an increase in public awareness of climate change in the 1980s and early 1990s, followed by a period of growing concern— mixed with the rise of conflicting positions—in the later 1990s and early 2000s.
