CLIMATE SCIENCE: An Off-Season Carbon Sink

Climate trade-off between black carbon and carbon dioxide emissions

There are various difficulties involved with comparing the effects of short-lived and long-lived atmospheric species on climate. Global warming potentials (GWPs) can be computed for pulse emissions of short-lived species. However, if the focus is on the long-term effect of a pulse emission occurring today, GWPs do not factor in the fact that if a radiative forcing is applied for a short period,...

An update on source-to-sink carbon partitioning in tomato

Plant growth and carbon metabolism are closely associated since carbohydrate in the form of sucrose generated by photosynthesis, provides the primary source of building blocks and energy for the production and maintenance of biomass. Regulation of carbon partitioning between source and sink tissues is important because it has a vast influence on both plant growth and development. The regulation...

Editorial: Climate Science: An Invitation for Physicists.

Climate science is rooted in physics and in many of the methods used by physicists. Although it’s a cliché to say that the practice of science changed dramatically with the advent of the digital age, computers have had an enormous impact on the growth and evolution of climate science. Before computing, progress in explaining observations or making predictions in the physical sciences, including...

The carbon sink in intact tropical forests.

To quantify the carbon (C) sink in intact tropical forests, Pan et al. (2011) multiplied ‘...region-specific estimates of C density or change in C density times the associated areas represented by the region-specific estimates.’ A retrospective interpolation based on their numbers provides insight into the possible causes of a C sink in intact tropical forests. First, however, there are two rea...
