Carbon dioxide, methane levels in the atmosphere hit ‘record highs’ last year – but only since 1959!

We’ll ignore any climate-related assertions in this article and try to look at actual information. How much of the variation of the trace gases mentioned would have occurred anyway, regardless of human activities? As the article says: ‘Carbon dioxide and methane levels have been higher in the far ancient past’. The world obviously didn’t self-destruct back then, so maybe a bit of context there for these latest ‘records’. It’s also known that warmer oceans absorb less carbon dioxide from the atmosphere – an entirely natural process.

The 2.8 parts per million increase in carbon dioxide airborne levels from January 2023 to December, wasn’t as high as the jumps were in 2014 and 2015, but they were larger than every other year since 1959, when precise records started, says PBS Online.

Carbon dioxide’s average level for 2023 was 419.3 parts per million, up 50% from pre-industrial times.

Last year’s methane’s jump of 11.1 parts per billion was lower than record annual rises from 2020 to 2022. It averaged 1922.6 parts per billion last year.

It has risen 3% in just the past five years and jumped 160% from pre-industrial levels showing faster rates of increase than carbon dioxide, said Xin “Lindsay” Lan, the University of Colorado and NOAA atmospheric scientist who did the calculations.

Methane emissions in the atmosphere come from natural wetlands, agriculture, livestock, landfills and leaks and intentional flaring of natural gas in the oil and gas industry.

Carbon dioxide and methane levels have been higher in the far ancient past, but it was before humans existed. [Talkshop comment – hint for alarmists there?]
. . .
The shift last year from a three-year La Nina, the natural cooling of parts of the central Pacific that changes weather worldwide, to a warm El Nino, played a role in dampening methane’s increasing rate in the air and spiking carbon dioxide levels, Lan said.

That’s because methane’s biggest emissions comes from wetlands, which during a La Nina is wetter in much of the tropics, creating more microbes in the lush growth to release methane, Lan said. The La Nina ended mid year last year, giving way to a strong El Nino.

Carbon dioxide levels in the atmosphere tend to rise higher during hotter El Ninos [Talkshop comment – another hint?], but the current one is starting to peter out, Lan said.

    Gives the causation to the El Ninos.

    Indeed, oldbrew!

    Good old Henry’s law.

    It’s curious how “climate scientists” are utterly unaware of the implications of the most basic laws of physics, isn’t it?

    Re: “It’s also known that warmer oceans absorb less carbon dioxide from the atmosphere – an entirely natural process.”

    That hardly matters. CO2 (and other gases) are continually flowing in both directions between the oceans and the air, and when CO2 levels were near 280 ppmv the fluxes in both directions were nearly identical in magnitude. A 1°C increase in sea-surface temperature accelerates the flow of CO2 from ocean to air by about 3%. But a 50% increase in atmospheric CO2 level accelerates the flow of CO2 from air to ocean by 50%.

    That’s why the oceans are net absorbers of CO2 (“sinks”), rather than net emitters of CO2 (“sources”).

    UK pharma companies told to make fewer drugs in draft net zero guidelines

    Suggestion among an array of green proposals British companies urged to consider – 9 April 2024

    Other recommendations in the Treasury report, which have not been redacted, include advice to clothing companies to reduce the amount of cotton used in t-shirts or replace traditional textiles with lab-grown fabrics.

    The guidance was published by the Transition Plan Taskforce (TPT), which was established by HM Treasury and set up following the COP26 environmental conference in Glasgow.

    Re. ‘fewer drugs’: The Government said that it had removed this recommendation hours before the guidelines were published, following questions from The Telegraph.

    That’s how to run a country 😆

  9. There was no super El Nino which from SOI figures ended in Feb 2024

  10. oldbrew says:

    One minute they say the recent El Nino is/was one of the (5?) strongest on record. Then they say the sea surface temperatures can’t be explained by El Nino alone, but that the missing explanation is a problem for them.

    Climate models can’t explain 2023’s huge heat anomaly — we could be in uncharted territory – 19 March 2024

    Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed.

    Cleaning the atmosphere adds to global warming? YCMIU.

    Recent reductions in aerosol emissions have increased Earth’s energy imbalance – 03 April 2024

    Here, we investigate anthropogenic contributions to the imbalance trend using climate models forced with observed sea-surface temperatures. We find that the effective radiative forcing due to anthropogenic aerosol emission reductions has led to a 0.2 ± 0.1 W m−2 decade−1 strengthening of the 2001–2019 imbalance trend.
