It's been over 18 years since the Earth's temperature last rose - something that Dr Benny Peiser, from the Global Warming Policy Forum, says experts are struggling to understand.
He explains that we are now in the midst of a "crisis of credibility" because the global warming - and accompanied 'Doomsday' effects - that we were once warned about has not happened.
Scientists from the Intergovernmental Panel on Climate Change (IPCC) once predicted a temperature rise of 0.2 degrees per decade - but are now baffled by the fact our planet's temperature has not increased for almost two decades.
Speaking exclusively to Express.co.uk, Dr Peiser said: "What has happened is that the public has become more sceptical because they were told we are facing Doomsday, and suddenly they realise ‘Where is the warming that we were promised?’"
"They say we can predict the climate and the reality is that they can’t."
Because of this so-called "global warming hiatus", Dr Peiser says climate change is not as pressing of an issue as it once was, a fact that should be embraced by the scientific community.
"Climate change used to be a top priority but it has dropped quite significantly - other issues are more important for international meetings," he said.
"The reality is that they are quite relieved in a way, and we should all be relieved that it isn’t such a big problem at present.
"We might have much more time than many people once told us."
However, the reason behind the current pause in rising temperatures remains a mystery, and there are said to be more than 30 theories attempting to decipher what caused this stability.
Some scientists suggest the heat may have gone into the ocean, but Dr Peiser remains unconvinced by this theory.
"Something is clearly balancing out the warming effect of the CO2 [carbon dioxide]," he explained.
"It might be natural factors, it might be the ocean, no one knows for sure.
"It [the warming] could start anytime - and that is an indication that we don’t fully understand the climate.
"That’s a reality that most climate scientists are reluctant to admit."
