Seeing results of large emission cuts on global warming may take decades – study

In climate fantasy world, everything is near-constant except human-caused trace gas emissions. Pathetic that this is considered to be serious science, rather than juvenile nonsense.

Humans may need to “wait for decades” to see the results of large emission cuts on global surface temperatures, scientists have said.

Researchers in Norway used computer simulations to analyse various scenarios that looked at the effects of rapid reductions in several types of greenhouse gas emissions, such as carbon dioxide (CO2), methane and black carbon, says TalkTalk.

They found that although large-scale emission cuts are needed to achieve the global climate goals, it may take decades before the effects of the reductions on temperatures can be measured.

The researchers estimated that even for the most optimistic scenarios, it will take at least 15 years to establish the impact of emission cuts on global warming.

If we are to reach the Paris Agreement ambition of limiting global warming to no more than 2C – or less – the first step will be to slow down the warming process

Bjorn H Samset, of the Centre for International Climate and Environmental Research (Cicero) in Oslo, who is one of the authors of the study published in the journal Nature Communications, said: “Human-induced climate change can be compared with a tank ship at high speed and in big waves.

“If you want the ship to slow down, you will put the engine in reverse, but it will take some time before you start noticing that the ship is moving more slowly.
“It will also rock back and forth because of the waves.”

The Earth’s surface temperature has, on average, risen by 0.2C every 10 years over the last five decades.

Climate experts have attributed this rise in temperatures to human-induced emissions of greenhouse gases.

    Translation: by the time you find out your ‘carbon taxes’ were useless the money will be long gone.

  2. wyzelli says:

    Apparently it may take decades before the reduction in CO2 appears as well.

  3. Russell Johnson says:

    Every scam is like this you pay the tax but nothing changes. Nothing will stop the minute amount of CC that occurs. Whether it cools or warms all we can count on is timely adaptation…

    When you see something called Centre for International Climate and Environmental Research you know there will not be any real science carried in there. All you get from there are emotional responses to pseudo science backed up by very bad computer programming of models that can not be validated.

    Model suggests it could take decades for planet to start cooling after emissions are reduced
    July 8, 2020 by Bob Yirka, Phys.org

    ‘As the planet continues to heat up due to human-caused greenhouse gas emissions, scientists continue to try to predict how the planet will respond. In this new effort, the researchers wondered what might happen if the people of the world finally saw the light and made serious efforts to reduce greenhouse gas emissions.’

    What ‘light’, Bob? Evidence-free assertions of human effects don’t count.
