    Great news altogther.

    How would you know? It's odourless.

    No. Variations in Earth’s orbit alter the amount of energy Earth receives from the Sun.

    However CO2 levels in the atmosphere always tracked closely those energy levels.




    But your question is a strawman, as its logic is inadequate to these phenomena. You seem to be trying to postulate some linear "cause and effect". But that is not the way complex systems such as we are talking about behave. Rather, you find "cause and effect" diminishes, and instead you begin to observe such phenomena as emergence, spontaneous order, adaptation, and feedback loops, among other phenomena, as complexity of the system increases.

    Of course, the complexity inherent in the "system" involved in planetary climate regulation is immense.

    Warmer, wetter, more CO2.

    Plants gonna love this.

    Sure. Some plants very far north gonna be happy out.

    But probably not the plants in the path of the encroaching expanding Sahara desert. (Which may have reached Europe by the middle of this century according to some predictions.)

    Or the plants under water... Or even the plants far enough north, but affected by the the migration of millions of people from low-lying, too hot, regions like Bangladesh into northern Europe etc...

    Why all the glib simplifications anyway? Is it just you like to bang on a preferred ideological drum, without care for the actual arguments?

    The shocker with 2016 is that CO2 is rising, but human emitted CO2 is not. Or just a bit. Not enough to make a fuss about, but just enough to employ thousands of scientists and rake in billions in "levies" and extra taxes.


    Record surge in atmospheric CO2 seen in 2016 - BBC News

    Concentrations of CO2 in the Earth's atmosphere surged to a record high in 2016, according to the World Meteorological Organization (WMO).
    Last year's increase was 50% higher than the average of the past 10 years.le.

    But all is well

    Global carbon growth stalls as US coal continues to slump - BBC News


    Declining consumption of coal in the US last year played a significant role in keeping down global emissions of carbon dioxide, according to a new report.
    The Global Carbon Project annual analysis shows that CO2 emissions were almost flat for the third year in a row, despite a rise in economic growth.
    The slowdown in the Chinese economy since 2012 has also been a key factor limiting carbon.
    Experts believe it is too early to say if global CO2 emissions have peaked.
    This is not entirely unexpected. El Nino occurs when ocean temperatures rise. The El Nino of 2016 was a particularly strong one comparable to the one in 1998. When ocean temperatures rise; CO2 is out gassed as a natural phenomena.

    El Niño and a record CO2 rise

    Published online 13 June 2016

    The recent El Niño event has elevated the rise in CO2 concentration this year. Here, using emissions, sea surface temperature data and a climate model, we forecast that the CO2 concentration at Mauna Loa will for the first time remain above 400 ppm all year, and hence for our lifetimes.
    Also CO2 sinks are known to be increasing faster than expected, reconcile those two facts with the way in which this is actually reported.


    Recent pause in the growth rate of atmospheric CO2 due to enhanced terrestrial carbon uptake

    Abstract
    Terrestrial ecosystems play a significant role in the global carbon cycle and offset a large fraction of anthropogenic CO2 emissions. The terrestrial carbon sink is increasing, yet the mechanisms responsible for its enhancement, and implications for the growth rate of atmospheric CO2, remain unclear. Here using global carbon budget estimates, ground, atmospheric and satellite observations, and multiple global vegetation models, we report a recent pause in the growth rate of atmospheric CO2, and a decline in the fraction of anthropogenic emissions that remain in the atmosphere, despite increasing anthropogenic emissions. We attribute the observed decline to increases in the terrestrial sink during the past decade, associated with the effects of rising atmospheric CO2 on vegetation and the slowdown in the rate of warming on global respiration. The pause in the atmospheric CO2 growth rate provides further evidence of the roles of CO2 fertilization and warming-induced respiration, and highlights the need to protect both existing carbon stocks and regions, where the sink is growing rapidly.

    Actually contrary to the hysterical rantings of the alarmists - the Sahara desert is actually shrinking as rainfall increases across the region in the past 20 years

    https://www.forbes.com/sites/jamesta.../#26c2c54727f6


    In 2009 scientists at Boston University examined satellite data and discovered a long-term shift from dryer to wetter conditions throughout the Sahara Desert. As reported by BBC News, “satellite images from the last 15 years do seem to show a recovery of vegetation in the Southern Sahara.”
