This year's El Niño, which is linked to global climate fluctuations, is the worst in more than 15 years, according to the UN's World Meteorological Organisation WMOO).
Founded four years ago, the institute advises third world countries on climate fluctuations, helping them to better plan what crops to grow and to anticipate floods and droughts.
The IPCC has attributed the pause to natural climate fluctuations caused by volcanic eruptions, changes in solar intensity, and the movement of heat through the ocean.
The disease may have arrived in waves, having been reimported multiple times, as a result of climate fluctuations that affected rodent populations in Asia.
Later, the satellite record was adjusted to filter out the effects of natural, short-term climate fluctuations like the El Nino phenomenon and temporary cooling produced by sun-blocking haze from volcanic eruptions.
It's not the sun, not natural climate fluctuations, not some bug in a computer model.
Multi-decadal climate fluctuations in the NW Pacific Ocean also affect seawater temperature.
This initiative successfully coped with existing climate fluctuations and reduced climate change-related risks.
Regions of vegetation transitions (ecotones) are known to be highly sensitive to climate fluctuations.
