A group of scientists and policy makers have claimed that the wider theory of global warming proposed by global climatologists cannot be trusted.
According to the scientists, global warming has been an ongoing process since a long time but the pace has slowed to a greater extent over a century or more now.
While the temperatures are still high by historical standards, the scientists say rate of warming has slowed in the last 15 years.
The study found that the temperature was slightly below the mark as predicted by the climate models between 1998 and 2013.
Climatologist Dr James Risbey, who led the study, and colleagues analysed the ability of current climatic models and investigated how they reproduce temperature observations for the past 15-year period.
Researchers say climate change models can be explained by El Niño and La Niña, the much-talked weather phenomenon currently.
Following review of the data for the period 1950 to 2013, scientists discovered that the climatic models were under and overestimated when both the weather phenomenon were taken into account.
According to the study, temperature changes in the Pacific Ocean can explain the fluctuating climate models and their discrepancies.
“The question of how climate model projections have tracked the actual evolution of global mean surface air temperature is important in establishing the credibility of their projections,” the researchers said.
They further said, “Some studies and the IPCC Fifth Assessment Report suggest that the recent 15-year period (1998–2012) provides evidence that models are overestimating current temperature evolution.”
- Experts are clueless about why global warming was over or underestimated by the climatologists
- Changes in temperature in the Pacific can help in explaining climate models, claims the study
- According to a new study, these climatic trends are consistent with El Niño and La Niña
- The data collected between 1950 and 2013 showed correlation between models and weather
- The climatic models can also give indications about the El Niño occurrence
