From NOT A LOT OF PEOPLE KNOW THAT

CO2 emissions still growing, say IEA:
Global CO2 emissions from energy combustion and industrial processes1 rebounded in 2021 to reach their highest ever annual level. A 6% increase from 2020 pushed emissions to 36.3 gigatonnes (Gt), an estimate based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy, economic and weather data.
The Covid-19 pandemic had far-reaching impacts on energy demand in 2020, reducing global CO2 emissions by 5.2%. However, the world has experienced an extremely rapid economic recovery since then, driven by unprecedented fiscal and monetary stimulus and a fast – although uneven – roll-out of vaccines. The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions, which led to more coal being burnt despite renewable power generation registering its largest ever annual growth.
Emissions increased by almost 2.1 Gt from 2020 levels. This puts 2021 above 2010 as the largest ever year-on-year increase in energy-related CO2 emissions in absolute terms. The rebound in 2021 more than reversed the pandemic-induced decline in emissions of 1.9 Gt experienced in 2020. CO2 emissions in 2021 rose to around 180 megatonnes (Mt) above the pre-pandemic level of 2019.
The 6% increase in CO2 emissions in 2021 was in line with the jump in global economic output of 5.9%. This marks the strongest coupling of CO2 emissions with Gross domestic product (GDP) growth since 2010, when global emissions rebounded by 6.1% while economic output grew by 5.1% as the world emerged from the Global Financial Crisis.

Although a large rise was inevitable following the lockdowns of 2020, the significant fact is that emissions are higher than in 2019. Given that the global economy still has not fully recovered from the pandemic, we should expect further increases in emissions this year.
Rather a misleading headline. It would be better if it read: ‘Accumulated total of CO2 emitted from energy combustion & industrial processes since 1900 has risen to 36.3 Giga tonnes’. I wonder how they knew what the amount of CO2 from these processes was in 1900? The whole thing is an estimate. Treat it accordingly.
Remember, when human CO2 emissions go lower as in 2020, it makes no difference to measured atmospheric concentrations which are always increasing.
However, when they go higher, They are responsible for all the measured increase.
“CO2 Emissions Hit Record High in 2021”
I had noticed it looked unusually green and verdant outside recently…
Thanks Paul.
the interesting fact here is an actual link between CO2 levels and human activity
on theother hand it could just be cooler conditions caused a drop in CO2 followed by a rise in earth temp with ocean warming April to November.
Will we blame the next expected fall with 5 months cooling on the fall in earth temperature or the Ukraine crisis?
CO2 emissions were record high in 2021, while the planet’s global temperatures according to UAH are showing no warming at all since 2015.
Any comments ?
According to the Keepers of the Holy Trends, this is caused by “random effects” and everything will be back on track shortly.
Point one…UAH TLT temperatures are driven by the net flow of energy/heat in/out of the layer. CO2 is only one among many factors that participate in the modulate of energy/heat in the UAH TLT layer.
Point two…UAH TLT is only a small portion of the climate system. It happens to have a low heat capacity which means the temperature exhibits a lot of variation. There are various heat flux processes that are moving the heat around in the climate system. These include DWIR radiation, UWIR radiation, sensible, latent, and shortwave radiation.
Point three…The ocean takes up 90% of the planetary energy imbalance. 2021 ended up being another record year in terms of oceanic heat content during the period of record. UAH TLT can only diverge from OHC for so long until it is forced to equilibriate with the ocean. As long as the planetary energy imbalance remains positive UAH TLT will go higher. It might pause for another 10 years or it might start going up again next year. But it will go up. The laws of thermodynamics say so.
HURRAY !!!!! Lots more food !!!! CO2 is plant food and is helping “green” the planet. Some parts of our deserts are becoming green because plants are able to grow with lots more CO2 (plant food). Why is this SUCH A CRIME ????? There are more people on the planet – we are told – and they all need feeding so why the PANIC ????????????????????
it looks terrifying , but when we convert it in watts/m2 , the real climate unit , the impact on Earth is not so impressive , only a few milli degrees per year as the AGGI shows it :
Just think about when China increases their mega coal fired plants with hundreds of new ones.
