Isolating the influence of climatic change from all the other trends is difficult, but one recent Stanford University study found that increases in global production of maize and wheat since 1980 would have been about 5% higher were it not for climate change.
Thus, instead of selecting one single "best" model, we fitted 104 variants of a statistical model with P as the response variable (see Methods, Figures 3c and 3d and Additional file 1), incorporating different measures derived from all three climatic indices (see Methods and Additional file 1).
They occur in all climatic zones, from boreal to tropical, and include bogs, fens, herbaceous marshes, woody swamps, shallow water bodies, riverine floodplains, and coastal beaches.

But Périgord black truffles, the Rolls Royce of truffles, seem to be suffering from a climatic trend toward hotter and drier summers in their native habitats of southwestern France and Spain.
Soils were selected from a climatic and elevational gradient in the Pacific Northwest.

Spalax is safeguarded all of its life underground from aboveground climatic fluctuations and predators.
On the Central and Northern Kuril Islands, environmental changes during the Middle and Late Holocene resulted both from climatic fluctuations and from repeated fallout of volcanic ash.
Bioclimatic suitability for RVFV based on vector species from current transmission zones may differ from climatic requirements of competent vectors in the US and EU.
