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.
