Variability is not new to food and agribusiness, however climate change, geopolitical instability, and technological advances are now impacting the sector more than ever before.

Climate researchers from the Helmholtz Young Investigators Group ECUS at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Potsdam have now investigated how temperature variability changed as the Earth warmed from the last glacial period to the current interglacial period.

Gentine and his team are now exploring ways to model how biosphere - atmosphere interactions may change with a shifting climate, as well as learning more about the drivers of photosynthesis, in order to better understand atmospheric variability.

Observed changes in ocean heat content have now been shown to be inconsistent with simulated natural climate variability, but consistent with a combination of natural and anthropogenic influences both on a global scale, and in individual ocean basins.

Thanks for publishing this, there are folks who denigrated the work of scientists that claimed a solar - climate (temperature) link because the variability in solar energy output just wasn't enough to explain the temperature swings, and perhaps they now realize that there could be another mechanism - similar to a transistor where small changes in gate voltage can affect large changes in power transmission - whereby solar activity can create significant effects on temperature.

Since there is now an almost century - long record of these break up dates, it makes sense to look at them as potential indicators of climate change (and interannual variability).

Ironically, while some continue to attack this nearly decade - old work, the actual scientific community has moved well beyond the earlier studies, focusing now on the detailed patterns of modeled and reconstructed climate changes in past centuries, and insights into the roles of external forcing and internal modes of variability (such as the North Atlantic Oscillation or «NAO» and the «El Nino / Southern Oscillation» or «ENSO») in explaining this past variability.

In many cases, it is now often possible to make and defend quantitative statements about the extent to which human - induced climate change (or another causal factor, such as a specific mode of natural variability) has influenced either the magnitude or the probability of occurrence of specific types of events or event classes.»

A more reasonable natural variability / forcing argument might go something like this: 1) There is natural variability of climate due to solar activity 2) Climate is changing now 3) Forcing can result in climate change, but the response of the C cycle to forcing is poorly understood 4) Forcing is happening now 5) Forcing and / or solar activity could be to blame for current warming trends Is this unreasclimate due to solar activity 2) Climate is changing now 3) Forcing can result in climate change, but the response of the C cycle to forcing is poorly understood 4) Forcing is happening now 5) Forcing and / or solar activity could be to blame for current warming trends Is this unreasClimate is changing now 3) Forcing can result in climate change, but the response of the C cycle to forcing is poorly understood 4) Forcing is happening now 5) Forcing and / or solar activity could be to blame for current warming trends Is this unreasclimate change, but the response of the C cycle to forcing is poorly understood 4) Forcing is happening now 5) Forcing and / or solar activity could be to blame for current warming trends Is this unreasonable?

Again, natural variability has been ignored in order to support a particular point of view, with climate change advocates leaping on the acceleration to further their cause and the climate change sceptics now using the slowing down to their own benefit.

Tim Ball on global warming: «The climate is changing all the time, and what's going on right now is well within natural variability.»

In 1990, two years after NASA scientist James E. Hansen issued his now famous warning about climate change during a congressional hearing, Lindzen started taking a publicly contrarian stance when he challenged then - senator Gore by suggesting in the Bulletin of the American Meteorological Society that the case for human - induced global warming was overstated and that natural climate variability could explain things just as easily.

«We don't fully understand how to input things like changes in the oceans, and because we don't fully understand it you could say that natural variability is now working to suppress the warming,» Jones admitted to the paper, apparently acknowledging what skeptical climate scientists have been attempting to convey for years.

Favourite plays include hyper - focus on one, extremely speculative study (T&S 09); misrepresenting the potential for abrupt cooling in the C21st, dismissing the dominance of the centennial forced trend, misrepresenting deglacial abrupt climate change; grossly over-stating the accuracy and utility of pre-CERES TOA reconstructions (especially the synthetic, non-observational ISCCP - FD reconstruction); hyper - focus on interannual OHC variability; confusion of cause and effect with long - term trends in OHC (CO2 forcing denial) and general inability to see that natural variability from now on will be riding up a forced trend which will increasingly dominate climate behaviour.

Both documented and undocumented changes due to man - made interventions, natural variability, and climate change have now been revealed.»

This global warming, climate change, climate variability farce has been going on for over 30 yrs and is no closer now to any form of a global agreement than when it first started.

What the paper does focus on, Hansen said, is determining whether extreme weather events like the Texas heat wave can be attributed to climate variability — the natural ups and downs in seasonal temperature — or to the global upward trend in summer temperatures that science now links with climate change.

Like Prof Curry, Prof Jones also admitted that the climate models were imperfect: «We don't fully understand how to input things like changes in the oceans, and because we don't fully understand it you could say that natural variability is now working to suppress the warming.

2) AR4 SYR, p 50, column 1, line 20: After 50 %, insert ``, as a consequence of climate variability and change» In both places, the changed statements will now read, «By 2020, in some countries, yields from rainfed agriculture could be reduced by up to 50 %, ``, as a consequence of climate variability and change.»
