To check whether warm winters have already attenuated the advance in spring phenology, an international team of researchers from China, Belgium, France, Spain, Switzerland and Germany investigated the change in the sensitivity of leaf unfolding to climate warming using long - term observations for seven dominant European tree species at 1245 sites in Central Europe.

The study provides the first large - scale empirical evidence for a declining sensitivity of spring phenology to warming in mature trees for Central Europe.

For this work, the ITC researchers worked with the USA National Phenology Network (USANPN) and earlier this year they published a quality - checked phenological dataset in Scientific Data.

Shows that a suite of modeled and derived measures (produced from daily maximum — minimum temperatures) linking plant development (phenology) with its basic climatic drivers provide a reliable and spatially extensive method for monitoring general impacts of global warming on the start of the growing season

Intercomparison, interpretation, and assessment of spring phenology in North America estimated from remote sensing for 1982 to 2006.

Combine the satellite trend with the surface observations and the umpteen non-temperature based records that reflect temperature change (from glaciers to phenology to lake freeze dates to snow - cover extent in spring & fall to sea level rise to stratospheric temps) and the evidence for recent gradual warming is, well, unequivocal.

«For long - distance migrants climate change may advance the phenology of their breeding areas, but the timing of some species» spring migration relies on endogenous rhythms that are not affected by climate change.

We might be tempted to simply include dynamic phenology in a climate model for all applications (again, assuming we can realistically simulate leaf variations).

Other circumstances that have high plausibility of accelerating extinctions include climatically induced loss of keystone species, collateral loss of species not necessarily affected by climate directly but dependent on species removed by climate change (for example, the myriad species dependent on coral - building species, see below), and phenology mismatches (disruption of the links between a species» yearly cycle and the seasons)(Dawson et al., 2011; NRC, 2011a).

«The study, carried out by 12 research groups, showed — for the first time — an acceleration in seasonal timings (phenology) at an environment - wide scale.

First, they discuss phenology (how nature changes through the seasons) as evidence for changing climate.

To quantify the contribution of the UHI effect to phenological variation is therefore another hot topic for the future in the field of phenology.»

Ice and phenology aren't so useful for detection in that sense because they are qualitative measures and it's hard to extract relative magnitudes or spatial patterns from them.
