A Remarkable Year for Earth's Climate. 2021 was consistent with the long-term human-caused global warming trend of about 0.2 °C (0.36 °F) per decade. From India to England, Russia, China, New Zealand, the U.S., Indonesia, Uganda, Germany, ... extreme precipitation and flooding over the span of just a few months.
Recent warming has driven many terrestrial and freshwater species poleward and towards higher altitudes. [228] For instance, the range of hundreds of North American birds has shifted northward at an average rate of 1.5 km/year over the past 55 years. [229] Higher atmospheric CO 2 levels and an extended growing season have resulted in global ...
A global energy crisis began in the aftermath of the COVID-19 pandemic in 2021, with much of the globe facing shortages and increased prices in oil, gas and electricity markets. The crisis was caused by a variety of economic factors, including the rapid post-pandemic economic rebound that outpaced energy supply, and escalated into a widespread ...
The list of climate change controversies (or list of global warming controversies) concerns past or present public debates over certain aspects of climate change: whether it is occurring (climate change deniers dispute this), how much has occurred in modern times, what has caused it, what its effects will be, whether action should be taken to curb it now or later, and so forth.
1 February 2022: a study published in PLOS Climate reported that, in 2019, 57% of the global ocean surface recorded extreme heat, compared to 2% during the Second Industrial Revolution, and that, between the 1980s and 2010s, the global mean normalized heat index increased by 68.23%. [ 7] Researchers stated that "many parts of the subtropical ...
Future global warming potential for long lived drivers like carbon dioxide emissions is not represented. The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre ...
The Nature article referenced recent IPCC Special Reports (2018, 2019) suggesting individual tipping points could be exceeded with as little as 1—2 °C of global average warming (current warming is ~1 °C), with a global cascade of tipping points possible with greater warming.
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy ...
