The rate and extent of global biodiversity change is surpassing our ability to measure, monitor and forecast trends. We propose an interconnected worldwide system of observation networks — a global biodiversity observing system (GBiOS)…
Submillimetre astronomy is the prime technique to unveil the birth and early evolution of stars and galaxies in the local … and distant Universe.
We present a reconstruction of Antarctic mean surface … temperatures over the past two centuries based on water … stable isotope records from high-resolution, precisely dated … ice cores. Both instrumental and reconstructed temperatures … indicate large interannual to decadal scale variability…
Stable isotope measurements from ice cores have long been regarded as proxies for local … temperature, and recent work shows that a strong isotope-temperature relationship exists … even on interannual timescales, especially if multiple cores are used and a regional (rather … than local)…
Most of what has been said about modern Antarctic climate change is based on studies of … meteorological observations that extend back the 1950s. Most attention to Antarctic ice core … records is focused on the timescale of glacial-interglacial cycles.
Ice-core records are a key resource for reconstructing Antarctic climate. However, a … number of physical processes preclude the simple interpretation of ice-core properties such as oxygen … isotopic ratios in terms of climate variables like temperature or sea-level pressure. We show that welldated…
A sparse network of meteorological observations in Antarctica extends back only to the late 1950s, making it difficult to characterize Antarctica's climate behavior in the context of natural climate variability and global warming. We show that composites of stable isotope (dD and d18O)…
