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]
A climate spiral (sometimes referred to as a temperature spiral [3] [4]) is an animated data visualization graphic designed as a "simple and effective demonstration of the progression of global warming", especially for general audiences. [5]
As a method to address global warming, the IPCC 2018 report indicated that the potential for global temperature reduction was "small," yet was in high agreement over the recognition of temperature changes of 1-3 °C on a regional scale. [1] Limited application of reflective surfaces can mitigate urban heat island effect. [3]
For the extended RCP2.6 scenario, global warming of 0.0 to 1.2 °C is projected for the late 23rd century (2281–2300 average), relative to 1986–2005. [34] For the extended RCP8.5, global warming of 3.0 to 12.6 °C is projected over the same time period. [34]
For the six SRES marker scenarios, IPCC (2007:7–8) gave a "best estimate" of global mean temperature increase (2090–2099 relative to the period 1980–1999) of 1.8 °C to 4.0 °C. [20] Over the same time period, the "likely" range (greater than 66% probability, based on expert judgement) for these scenarios was for a global mean temperature ...
The Arctic was historically described as warming twice as fast as the global average, [40] 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 ...
The report identified and corrected errors in satellite temperature measurements and other temperature observations, which increased scientific confidence in the conclusion that lower atmosphere is warming on a global scale: "There is no longer a discrepancy in the rate of global average temperature increase for the surface compared with higher ...
