To limit global warming to less than 1.5 °C global greenhouse gas emissions needs to be net-zero by 2050, or by 2070 with a 2 °C target. [271] This requires far-reaching, systemic changes on an unprecedented scale in energy, land, cities, transport, buildings, and industry.
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 ...
These numbers show that awareness of global warming was increasing in the United States. [300] A Gallup poll showed that 62% of Americans believe that the effects of global warming were happening in 2017. [301] In 2019, Gallup poll found that one-third of Americans blame unusual winter temperatures on climate change. [302]
It is clear that the ocean is warming as a result of climate change, and this rate of warming is increasing. [2]: 9 The global ocean was the warmest it had ever been recorded by humans in 2022. [13] This is determined by the ocean heat content, which exceeded the previous 2021 maximum in 2022. [13]
The Arctic was historically described as warming twice as fast as the global average, [39] but this estimate was based on older observations which missed the more recent acceleration. By 2021, enough data was available to show that the Arctic had warmed three times as fast as the globe - 3.1°C between 1971 and 2019, as opposed to the global ...
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.
The long-form article depicts a worst-case scenario of what might happen in the near-future due to global warming. The story was the most-read article in the history of the magazine. [1] [2] The article became the inspiration for The Uninhabitable Earth: Life After Warming, a book-length treatment of the ideas explored in the original essay. [3]
Global warming is an aspect of modern climate change, a term that also includes the observed changes in precipitation, storm tracks and cloudiness. As a consequence, glaciers worldwide have been found to be shrinking significantly .
