IPCC keeps downplaying the danger even as reality strikes

Record hot sea surface The daily sea surface temperature (SST) between 60°South and 60°North was at a record high on April 2, 2023, i.e. the highest temperature in the NOAA record that started in 1981, as illustrated by the above image. The black line shows this year's SST, up to April 2, 2023. The orange line shows last year's SST, i.e. 2022. The thicker grey line shows SST in the year 2020, when annual temperatures on land and ocean reached a record high, since 2020 was an El Niño year.  This record high sea surface temperature comes as we're moving into a new El Niño, as illustrated by the image on the right, adapted from NOAA . There are further reasons why this uptick doesn't come unexpected. The emerging El Niño looks set to coincide with high sunspots, while the 2022 Tonga submarine volcano eruption did add a huge amount of water vapor to the atmosphere, as discussed in an earlier post .  Greenhouse gas concentrations keep rising Reducing emissions is the right t...

There is no Carbon Budget

[ Sam Carana: "There is no carbon budget!" ] In the above image, the atmosphere is presented as a "bucket" filling with greenhouse gas pollution from fossil fuel use from 1870 to 2020. The image depicts the idea that there is some carbon budget left, before 1.5°C above pre-industrial will be reached. The Global Carbon Project has just issued an update of what it refers to as the Global Carbon Budget .  [ adapted from Global Carbon Budget 2022 ] The Global Carbon Project insists that there still is some carbon budget left, even as global fossil fuel C₂O emissions in 2021 were higher than 2020, and are projected to be higher again in 2022 than 2021, as illustrated by the image on the right. Arctic-news has long said that the suggestion of a carbon budget is part of a narrative that polluters seek to spread, i.e. that there was some budget left to be divided among polluters, as if polluters could safely continue to pollute for years to come before thresholds ...

Shortcomings of IPCC AR6 WGIII - Mitigation of Climate Change

In the video below,  U.N. Secretary-General António Guterres comments on the launch of the  IPCC AR6 WGIII SPM Mitigation  report.  [ U.N. Secretary-General António Guterres ] The  report has severe shortcomings, including:  The IPCC makes it look as if the temperature rise could be restricted to 1.5°C above pre-industrial and insists there was a carbon budget left, to be divided by using monetary analysis.  This narrative results in a failure to highlight in the SPM some key drivers of change (such as heat pumps in buildings and air taxis in transport) and in inappropriately referring to such key drivers of change as 'options', while failing to mention the best policies to achieve the necessary changes, i.e. through local feebates. The agenda behind this narrative becomes further evident in phrases such as “CCS could allow fossil fuels to be used longer, reducing stranded assets” and “oil and gas assets are projected to be more at risk of being stran...

What the IPCC impacts report is hiding

[ click on images to enlarge ] Above image is adapted from content by IPCC AR6 WGII and Peter Carter , expert IPCC reviewer and director of the Climate Emergency Institute .  The IPCC keeps hiding how much the temperature could already have risen and could rise over the next few years, the associated dangers, and the policies that could most effectively improve the situation.  1. Hiding the potential rise that has already unfolded One of the first issues that springs to mind is the IPCC's use of 1850-1900 as a baseline, which isn't pre-industrial as the Paris Agreement called for. Above image, adapted from a NASA image, shows a January 2022 temperature rise of 1.31°C versus 1885-1915. As the box underneath indicates, a further 0.1°C could be added for ocean air temperatures and another 0.1°C for higher polar anomalies. When calculating the temperature rise from pre-industrial , a further 0.79°C could be added for the period from 3480 BC to 1900, resulting in...

Is the IPCC creating false perceptions, again?

IPCC AR6 Report The Working Group I contribution to the Sixth Assessment Report (WG1 AR6) of the Intergovernmental Panel on Climate Change (IPCC) raises the question: Is the IPCC seeking to downplay the dire situation that we are in, again?  Downplaying the temperature rise from pre-industrial One of the first issues that comes up is the baseline. The IPCC uses 1850–1900 as a baseline, like it did before  (in SR1.5).  This is one out of many instances where the IPCC creates a perception that it would take many years before the 1.5°C threshold would be crossed. This 1850–1900 isn't pre-industrial. The Paris Agreement calls for pre-industrial as a base.  The IPCC image on the right shows a 1.09°C rise from 1850–1900. This isn't the rise to the year 2020, but it is the rise to the  period  from 2011 to 2020.  Instead, when taking the 2020 temperature rise and going back one century, NASA data show a 1.29°C rise from 1920, and this is a conservative ...
