Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

In that year, El Nio added to the increased warming caused by the build-up of heat-trapping emissions in the atmosphere, leading to that record-breaking heat. Humans have a direct effect on albedo through emitting industrial aerosols such as sulfates, which accumulate in the atmosphere due to the burning of fossil fuels.

The water south of Greenland has been cooling, so what causes that?

Real Climate

An AMOC weakening by 15 % thus cools the region at a rate of 0.15 x 10 14 W and according to model simulations can fully explain the observed cooling trend (2). Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces.

Unlike in years past, there is no longer any serious discrepancy between the records – which use multiple approaches for the ocean temperatures, the homogenization of the weather stations records, and interpolation. Southern Ocean trends. The least visited part of the ocean are the waters around Antarctica.

New study suggests the Atlantic overturning circulation AMOC “is on tipping course”

Real Climate

The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years. Figure adapted from Caesar et al., Nature 2018.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

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). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

A Nobel pursuit

Real Climate

The key aspects were the inclusion of water vapour feedback as temperatures increased, and the use of ‘convective adjustment’ to maintain stability of the lower atmospheric column. The basic issue stems from the different timescales of the ocean and atmosphere. Fred Singer, before his turn to the dark side).

Sea Level Rise is Already Threatening Communities

Union of Concerned Scientists

The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. That adds water to the oceans, which raises their level. Cool, right?)
