Sea level in the IPCC 6th assessment report (AR6)

Real Climate

My top 3 impressions up-front: The sea level projections for the year 2100 have been adjusted upwards again. The IPCC gives more consideration to the large long-term sea-level rise beyond the year 2100. And here is the key sea-level graphic from the Summary for Policy Makers: Source: IPCC AR6, Figure SPM.8.

New, Updated Carbon Majors Dataset Holds Promise for Researchers, Litigators

Union of Concerned Scientists

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere. Nearly two-thirds of industrial heat-trapping emissions can be traced to just 90 entities.

Why is future sea level rise still so uncertain?

Real Climate

Three new papers in the last couple of weeks have each made separate claims about whether sea level rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty. The last major revision (BedMap2) was in 2013 ( Fretwell et al., But there is more.

The world’s oceans are heading towards peak acidity?

A Greener Life

Their annual ‘State of the Global Climate’ report indicated that the accelerating pace of climate change was to blame for acidification and that the melting of ice sheets contributed to pushing sea level rises to new heights in 2021. And in just the past decade global sea levels have risen 4.5

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

While temperatures provide a measure of the Earth’s climate, it is even better to use the global sea level , which provides a far more reliable measure. The global sea level acts like the mercury in a thermometer because warmer water expands.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

The problems with the SPM are similar those from the previous fifth assessment report which prompted me to write a post in 2013. I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. mm increase every year.
