Natural forces cause some variability, but the 20-year average shows the progressive influence of human activity. [2] Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate.
This has led to increases in mean global temperature, or global warming. The likely range of human-induced surface-level air warming by 2010–2019 compared to levels in 1850–1900 is 0.8 °C to 1.3 °C, with a best estimate of 1.07 °C. This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C.
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 ...
The dominant cause of the warming since the 1950s is human activities. This scientific finding is based on a large and persuasive body of research. The observed warming will be irreversible for many years into the future, and even larger temperature increases will occur as greenhouse gases continue to accumulate in the atmosphere.
The Climatic Research Unit email controversy (also known as "Climategate") [2] [3] began in November 2009 with the hacking of a server at the Climatic Research Unit (CRU) at the University of East Anglia (UEA) by an external attacker, [4] [5] copying thousands of emails and computer files (the Climatic Research Unit documents) to various internet locations several weeks before the Copenhagen ...
That trend, combined with ocean warming which causes water to expand, has contributed to a more than doubling of the rate of sea-level rise over the past decade compared with the 1993-2002 period ...
Climate security is a political and policy framework that looks at the impacts of climate on security. Climate security often refers to the national and international security risks induced, directly or indirectly, by changes in climate patterns. It is a concept that summons the idea that climate-related change amplifies existing risks in ...
The tech giant claims millions of people were sent a warning before the deadly earthquake earlier this year.
