The observed reduction in surface warming trend over the period 1998 to 2012 as compared to the period 1951 to 2012, is due in roughly equal measure to a reduced trend in radiative forcing and a cooling contribution from natural internal variability, which includes a possible redistribution of heat within the ocean ( medium confidence ).

These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extra-tropical North Atlantic that play out on 40-60 year timescales (hence the name). Background. Is there merit to this argument?

The dramatic dimming of the red supergiant star Betelgeuse in 2019–20 was caused by a cold spot on the surface of the star causing a nearby gas cloud to cool and condense into obscuring dust, according to new findings. to an unprecedented magnitude +1.64 – three times fainter – by February 2020.

C is now 500 GtCO 2 starting from the beginning of 2020, with a 66% uncertainty range of 300–900 GtCO 2. This is known as the Zero Emissions Commitment to emissions of CO 2 (or ZEC).

Radiation therapy plays a vital role in the treatment of more than 50% of all cancer cases. In low- and middle-income countries, much of the population lacks access to radiation therapy. They note that the system’s footprint is similar to a standard CT system, though power and cooling requirements are greater. Karger AG, Basel).

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. The greatest temperature ever recorded on Antarctica occurred in February 2020, when the mercury hit 18.3C. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018.

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.

Much like big volcanic eruptions, the smoke from fire tornadoes can block radiation from the Sun and potentially cause temporary climatic cooling. In fact, in 2020, the National Weather Service issued its first-ever ‘fire tornado’ warning due to one of at least 5 firenadoes recorded in California that year.

By independently altering the chances that each crystal would emit photons, they showed that this so-called source purity is related to the visibility of interference fringes (a wave-like property) and path distinguishability (a particle-like property) by a simple mathematical expression first articulated by Qian and Agarwal in 2020.

For example, methane stayed roughly flat for about a decade from the late 1990s, but has increased rapidly since then – by nearly 16 ppb in 2020 over 2019. For other gases, the GWP depends on two different properties of the gas: how strongly it absorbs infrared radiation; and how long it stays in the atmosphere after it is emitted.

“It’s [the albedo is] kept the same” [False – for instance here is a paper (Loeb et al, 2020) comparing the changes in albedo in models to the CERES observations].
