The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and
human/cultural systems that may be irreversible on century time scales and have the potential …

Large quantities of organic carbon are stored in frozen soils (permafrost) within Arctic and
sub-Arctic regions. A warming climate can induce environmental changes that accelerate the …

▪ Abstract The Arctic is a key part of the global climate system because the net positive energy
input to the tropics must ultimately be resolved through substantial energy losses in high-…

The concurrent effects of increasing atmospheric CO 2 concentration, climate variability, and
cropland establishment and abandonment on terrestrial carbon storage between 1920 and …

The emergence of SARS-CoV-2 has resulted in >90,000 infections and >3,000 deaths.
Coronavirus spike (S) glycoproteins promote entry into cells and are the main target of antibodies…

The association of genetic variation with disease and drug response, and improvements in
nucleic acid technologies, have given great optimism for the impact of ‘genomic medicine’. …

The concentration of CO2 in the atmosphere has risen from close to 280 parts per million (ppm)
in 1800, at first slowly and then progressively faster to a value of 367 ppm in 1999, …

A process-based model was used to estimate global patterns of net primary production and
soil nitrogen cycling for contemporary climate conditions and current atmospheric C0 2 …

The Arctic climate is changing. Permafrost is warming, hydrological processes are changing
and biological and social systems are also evolving in response to these changing …

A major challenge in predicting Earth's future climate state is to understand feedbacks that
alter greenhouse-gas forcing. Here we synthesize field data from arctic Alaska, showing that …
