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 ...
Started in 2006, the American College & University Presidents' Climate Commitment (ACUPCC) was a “high-visibility effort” to address global warming (global climate disruption) by creating a network of colleges and universities that had committed to reduce their greenhouse gas emissions and accelerate the research and educational efforts of higher education to equip society to re-stabilize ...

Climate change has led to the United States warming by 2.6 °F (1.4 °C) since 1970. [20] The climate of the United States is shifting in ways that are widespread and varied between regions. [21] [22] From 2010 to 2019, the United States experienced its hottest decade on record. [23]
Furthermore, climate change may disrupt the ecology among interacting species, via changes on behaviour and phenology, or via climate niche mismatch. [9] The disruption of species-species associations is a potential consequence of climate-driven movements of each individual species in opposite directions.
The climate change policy of the United States has major impacts on global climate change and global climate change mitigation.This is because the United States is the second largest emitter of greenhouse gasses in the world after China, and is among the countries with the highest greenhouse gas emissions per person in the world.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
ΔT = average global temperature change (°C) E T = cumulative carbon dioxide emissions (Tt C) ΔC A = change in atmospheric carbon (Tt C) and, 1Tt C = 3.7 Tt CO 2. TCRE can also be defined not in terms of temperature response to emitted carbon, but in terms of temperature response to the change in radiative forcing: [10]
