Another dot on the graph

Real Climate

Depending on the product, 2021 was either the 5th, 6th or 7th warmest year, but in all cases, it is part of the string of warm years (since 2015) that have all been more than 1ºC warmer than the late 19th C. In contrast, CMIP6 model hindcasts/forecasts for this time period don’t show any cooling at all at these latitudes.

Should the official Atlantic hurricane season be lengthened?

Real Climate

Emanuel 2021 ; Hall et al. 2021 ; Knutson et al. The difference is due largely to the differences in the regional atmospheric response that occurs in concert with the SST warming. In particular, they don’t just respond to SST changes, but also how the atmosphere changes as the SSTs change. 2020 ), many others do not.

The CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

In my opinion the press conference on 9 August 2021 didn’t do justice to the vast effort that went into it. Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below).

Weather satellite sheds light on ‘Great Dimming’ of Betelgeuse star

Physics World

This, astronomers believe, allowed the cloud to cool and condense into dust that blocked some of Betelgeuse’s light. The satellite revealed that the star itself cooled by 140 °C. The Himawari-8 observations also suggest that something was happening to the atmospheric structure of Betelgeuse 10 months before the dimming.

In a Changing Climate, What Does a “Normal” Year of Wildfires Look Like?

Union of Concerned Scientists

While wildfires can and do occur all year round, this shift from cool and wet to warm and dry marks the start of wildfire season in the region. From 2000 to 2021, the average was more than 350 fires per year. During the 2000 to 2021 period, the average was nearly 11,000 acres—a 65% increase in size.

And also, let’s be clear, this mysteriously justified temperature series has been created explicitly to demonstrate a connection to the HS93 solar reconstruction – that was the case in the Soon et al (2015) paper, the Connolloy et al (2021) paper and now in this new Soon et al paper.
