Oct 5, 2017 · NASA’s Dr James Hansen and colleagues published a paper in 1981 that also used a simple energy balance model to project future warming, but accounted for thermal inertia due to ocean heat uptake. They assumed a climate sensitivity of 2.8C per doubling CO2, but also looked at a range of 1.4-5.6C per doubling.
Jul 24, 2019 · In fact, the only time in the past 2,000 years that nearly all of the Earth has undergone significant warming or cooling is the present period of change that began in the 20th century, according ...
Oct 19, 2023 · In a 2018 report, the Intergovernmental Panel on Climate Change (IPCC) stated that the average global temperature has risen about 1ºC (1.8ºF) since pre-industrial times. If the current rate of warming continues, this number is expected to nearly double in a relatively short time, reaching 1.5ºC (2.7ºF) between 2030 and 2052.
