Soares looks at short - term trends which are swamped by natural variations while ignoring the long - term correlation.

Both real - world observations and the team's simulations reveal that the abnormally strong winds — driven by natural variation in a long - term climate cycle called the Interdecadal Pacific Oscillation — have, for the time being, carried the «missing» heat to intermediate depths of the western Pacific Ocean.

Can you provide a more plausible mechanism explaning a cooling trend occasionally masked by natural variation?

Hypothesis «B» is that AGW is not basically sound science, that human activity has negligible impact on climate, and any notable changes we've observed recently are brought about by natural variation.

«Figuring out the exact DNA sequence variations responsible and how they influence the disease process should provide us with a guide for developing drugs that we hope could have a much larger effect than the one to six years produced by the natural variations, possibly even preventing symptom onset altogether.

Summary: The paper concluded that between 1880 and 2002, surface air temperature trends in China were strongly influenced by natural variations in solar intensity.

Soares looks at short - term trends which are swamped by natural variations.

Weather intensities are driven by natural variations and overall climate forcing.

Can you provide a more plausible mechanism explaning a cooling trend occasionally masked by natural variation?

While unlikely, this rate could have been potentially explained by natural variations in earthquake rates from naturally occurring swarms.

The team has also found evidence to silence a minority of sceptics who argue that what most astronomers take to be microlensing events are actually caused by natural variations in the intrinsic brightness of the stars being observed.

Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4

Fact: the null hypothesis of AGW (Alienpogenic global warming) theory — that that all global warming can be explained by natural variation — has never been rejected.
