Temperature data over the past five decades show faster warming of the global land surface
during the night than during the day. This asymmetric warming is expected to affect carbon …

The carbon balance of terrestrial ecosystems is particularly sensitive to climatic changes in
autumn and spring,,,, with spring and autumn temperatures over northern latitudes having …

Shifts in vegetation phenology are a key example of the biological effects of climate change,–
. However, there is substantial uncertainty about whether these temperature-driven trends …

Future climate warming is expected to enhance plant growth in temperate ecosystems and
to increase carbon sequestration,. But although severe regional heatwaves may become …

Climate change is shifting the phenological cycles of plants, thereby altering the functioning
of ecosystems, which in turn induces feedbacks to the climate system. In northern (north of …

The most important anthropogenic influences on climate are the emission of greenhouse
gases and changes in land use, such as urbanization and agriculture. But it has been …

THROUGHOUT the Northern Hemisphere the concentration of atmospheric carbon dioxide
rises in winter and declines in summer, mainly in response to the seasonal growth in land …

Variations in the amplitude and timing of the seasonal cycle of atmospheric CO2 have
shown an association with surface air temperature consistent with the hypothesis that …

Observations of a longer growing season through earlier plant growth in temperate to polar
regions have been thought to be a response to climate warming,,,,. However, data from …

Terrestrial ecosystems control carbon dioxide fluxes to and from the atmosphere, through
photosynthesis and respiration, a balance between net primary productivity and …
