As predicted in 1967 by Manabe and Wetherald , the stratosphere has been cooling. The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. Thompson et al. We are using the NOAA-STAR version 3.0 of these products (Zou et al.,
2018 (Fig. 2018 (our Fig. Of the 24 CMIP6 models, a full 23 underestimate the sea surface cooling in the ‘cold blob’ And most of the CMIP6 models even show a strengthening of the AMOC in the historic period, which past studies have shown to be linked to strong aerosol forcing in many of these models (e.g.
In the 2018 IPCC Special Report on Global Warming of 1.5°C in 2018, but they represent a significant update since AR5 in 2013. Source: Data from IPCC (2014), Rogelj et al (2018), and IPCC (2021). Source: Data from IPCC (2014), Rogelj et al (2018), and IPCC (2021). 2018) A new scenario resource for integrated 1.5 °C
There was a workshop in 2018 (that I attended) to discuss how one might go about doing something better – updating the data, improving quality control, and using models to better connect local or regional signals to the global means. and, like many of us, had found the then-current literature somewhat unsatisfactory. 0.6ºC (95% CI).
Fortunately, Manabe recently wrote a retrospective on his early work in response to receiving the Crafoord prize in 2018. 2018 ), but I think it’s fair to say that few modelers think it’s a useful tool anymore. In his 2018 retrospective, Manabe doesn’t discuss the issue at all. 9335-9350, 2018.
Extreme heat is not just an abstract notion: if we can’t cool our bodies enough, we’re in danger of neurological failure, organ failure and even death, with the risks highest for children and the elderly. On balance, clouds nearer the stratosphere warm us, whereas low-lying clouds tend to cool us because their greenhouse effect is smaller.
For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018. In the Arctic this has led to regional warming four times faster than the global average.
The company has products serving both quantum computing and the physical sciences, including a wide range of cryostats as well as dilution refrigerators that can cool samples to a few millikelvin. You’re combining your new role with your existing position at the University of Glasgow, where you’ve been since 2018.
The issue is that total human radiative forcing includes several parts that heat and some that cool, so counting separate heating contributions like this leaving out the cooling parts gives too much heating.). Human-source atmospheric methane now adds slightly less than 1 watt per square meter (W/m 2 ) of radiative forcing, versus 1.7
This study provides the most detailed mapping yet of how summer temperatures in 20 urban centers in California, Nevada, Utah, Arizona, Colorado, New Mexico and Texas affected different neighborhoods between 2018 and 2020. The researchers found even greater heat disparities in California than in other states.
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
It was a bold claim and some researchers initially struggled to accept the implications because it meant that energy must be flowing from the “cool” 6000 K surface of the Sun into the hotter corona – seemingly in violation of thermodynamics. This estimate was later revised upwards to 10 6 K and above.
Yet in spite of the 2018 explosion of a brand new Revolution Pipeline in Beaver County, we’ve done little to change our laws or protect people. The cooling down process, however, took a month and the radioactive plant would take years to decontaminate. We lost cooling in the reactor, but it’s okay now. Read more here.
Pyrocumulonimbus cloud over the 2018 Carr Fire (image by Jim Mackensen; source ). Much like big volcanic eruptions, the smoke from fire tornadoes can block radiation from the Sun and potentially cause temporary climatic cooling.
The new design overcomes the power limitations of a previous device built by Segev and collaborators in 2018, and can in principle be scaled up to incorporate hundreds of individual lasers. Innovative particle cooling techniques. The ALPHA collaboration demonstrated laser-cooling of antihydrogen atoms for the first time.

On September 10, 2018, the brand new Energy Transfer Revolution Pipeline in Beaver County exploded sounding like a meteor or airplane hit the ground. The flare structures were so hot they had to be cooled with water hoses and will need to be reinforced, according to the company. Read more here. DEP's investigation is ongoing.
This balance describes how much energy is being reflected back into space versus how much is being absorbed by our atmosphere; a positive change in the balance indicates that we’re taking more energy in (net warming) and a negative balance indicates that we’re reflecting more energy out (net cooling).
