    WMO: Climate Change Continues to Shatter Records, Disrupt Human Society - CleanTechnica
    https://cleantechnica.com/2023/04/24/wmo-report-highlights-continuous-advance-of-climate-change/

    Concentrations of the three main greenhouse gases — carbon dioxide, methane, and nitrous oxide — reached record observed highs in 2021, the latest year for which consolidated global values are available (1984-2021). The annual increase in methane concentration from 2020 to 2021 was the highest on record. Real-time data from specific locations show levels of the three greenhouse gases continued to increase in 2022.

    Ocean acidification: CO2 reacts with seawater resulting in a decrease of pH referred to as “ocean acidification.” Ocean acidification threatens organisms and ecosystem services. The IPCC Sixth Assessment Report concluded that “There is very high confidence that open ocean surface pH is now the lowest it has been for at least 26 [thousand years] and current rates of pH change are unprecedented since at least that time.”

    ...

    Record breaking rain in July and August led to extensive flooding in Pakistan. There were over 1700 deaths, and 33 million people were affected, while almost 8 million people were displaced. Total damage and economic losses were assessed at US$ 30 billion. July (181% above normal) and August (243% above normal) were each the wettest on record nationally.

    ...

    Record breaking heatwaves affected Europe during the summer. In some areas, extreme heat was coupled with exceptionally dry conditions. Excess deaths associated with the heat in Europe exceeded 15,000 in total across Spain, Germany, the UK, France, and Portugal.

    TUHO: Prubirsky kamen:

    Is it GMO a solution for climate change?

    According to the IPCC AR6 report, genetic improvements through modern biotechnology have the potential to increase climate resilience in food production systems with high confidence. However, technical, agroecosystem, socioeconomic, and political variables strongly influence and limit the uptake of climate resilient crops, particularly for smallholders with medium confidence. While biotechnology can be used as an adaptation strategy, there is low confidence that genetically modified (GM) crops can increase food security and nutrition in smallholder farming systems relative to alternative agronomic strategies. Therefore, it is not clear whether GMOs are a solution for climate change. (IPCC_AR6_WGII_Chapter05, IPCC_AR6_WGII_TechnicalSummary)

    Takze pokavad je ten AI comprehensive tak jinymi slovy to IPCC vubec systemove neresi kdyz to komunikuje jen jako "potential to increase climate resilience". Smutny.

    Mohli byste Hawkingovi napsat, ze klimatologie je fyzika, stejne jako meteorologie? On si asi mysli, ze klimatogove sice rozumi termodinamice, elektromagnetizmu ale ze uz nerozumi astronomii :)) Te rozumi asi jenom on.
    Jako chapu to zmateni, kdyz se mluvi dlouze o rostlinach, lidi si zacnou myslet "zeleni", ale to je zakladni neporozumneni toho fyzikalniho procesu uvnitr zivych organismu, s vstevnatou stavbou tela, fotosyntezou.
    Pro Hawkinga je fyzika asi jenom termonuklearni reakce a dal uz nic.

    Global Temperature Reconstruction Over Last 24,000 Years Show Today’s Warming “Unprecedented”

    btw kdyz uz jsme u tech rekonstrukci v delsich casovych horizontech, jeden z nejkompletnejsich za holocen z posledni doby:



    An extensive new multi-proxy database of paleo-temperature time series (Temperature 12k) enables a more robust analysis of global mean surface temperature (GMST) and associated uncertainties than was previously available. We applied five different statistical methods to reconstruct the GMST of the past 12,000 years (Holocene). Each method used different approaches to averaging the globally distributed time series and to characterizing various sources of uncertainty, including proxy temperature, chronology and methodological choices. The results were aggregated to generate a multi-method ensemble of plausible GMST and latitudinal-zone temperature reconstructions with a realistic range of uncertainties. The warmest 200-year-long interval took place around 6500 years ago when GMST was 0.7 °C (0.3, 1.8) warmer than the 19th Century (median, 5th, 95th percentiles). Following the Holocene global thermal maximum, GMST cooled at an average rate −0.08 °C per 1000 years (−0.24, −0.05). The multi-method ensembles and the code used to generate them highlight the utility of the Temperature 12k database, and they are now available for future use by studies aimed at understanding Holocene evolution of the Earth system.
