"A decrease in global annual catch for marine fisheries of about 1.5 or 3 million tonnes for 1.5 °C or 2 °C of global warming" is projected by one global fishery model cited in the report. [32] Coral reefs are projected to decline by a further 70–90% at 1.5 °C, and even more than 99% at 2 °C. [ 33 ] "
A Climate Data Record (CDR) is a specific definition of a climate data series, developed by the Committee on Climate Data Records from NOAA Operational Satellites of the National Research Council at the request of NOAA in the context of satellite records. [1]
The time at which global mean temperature is predicted to reach +2 °C compared to the pre-industrial period (1850–1900) is termed the "crossing year". [ 3 ] As a global target for limiting emissions, the 2 °C target has frequently been criticized for being higher than desirable, [ 1 ] [ 4 ] because two degrees of warming will have serious ...
The 2018 IPCC report said to limit temperature rises to 1.5C the world would have to cut carbon emissions by 45% on 2010 levels by 2030, and to net zero – with any remaining pollution absorbed ...
The inscription '1.5 °' at Neustädter Elbufer in Dresden for adhering to the 1.5-degree target by Fridays for Future (2022). The 1.5-degree target (also known as the 1.5-degree limit) is the climate goal of limiting the man-made global temperature increase caused by the greenhouse effect to 1.5 °C on a 20-year average, calculated from the beginning of industrialization to the year 2100.

The growth rate from 1990 to 1999 averaged 1.1% per year. Between the years 2000–2009, growth in CO 2 emissions from fossil fuel burning was, on average, 3% per year, which exceeds the growth estimated by 35 of the 40 SRES scenarios (34 if the trend is computed with end points instead of a linear fit).

To accommodate the lowest points on Earth, the model starts at a base geopotential altitude of 610 meters (2,000 ft) below sea level, with standard temperature set at 19 °C. With a temperature lapse rate of −6.5 °C (-11.7 °F) per km (roughly −2 °C (-3.6 °F) per 1,000 ft), the table interpolates to the standard mean sea level values of ...
