Sentences with phrase «global change detection»
The NSIDC DAAC provides data and information on snow, sea ice, glaciers, ice sheets, ice shelves, frozen ground, soil moisture, cryosphere, and climate interactions, in support of research in global change detection, model validation, and water resource management.

There are also global datasets of indices representing the more extreme aspects of climate called CLIMDEX, providing a list of 27 core climate extremes indices (so - called the «ETCCDI» indices, referring to the «CCl / CLIVAR / JCOMM Expert Team on Climate Change Detection and Indices»).
It therefore makes no sense to only attribute changes from after the point of detection since you'll miss the first 2 sigma of the change... Similarly, we can still calculate the forced component of a change even if it isn't the only thing going on, and indeed, before it is statistically detectable in the global mean temperature anomaly.

Scaling factors derived from detection analyses can be used to scale predictions of future change by assuming that the fractional error in model predictions of global mean temperature change is constant (Allen et al., 2000, 2002; Allen and Stainforth, 2002; Stott and Kettleborough, 2002).
A: «Internal variability versus anthropogenic forcing on sea level and its components» B: «The rate of sea - level rise» C: «Quantifying anthropogenic and natural contributions to thermosteric sea level rise» D: «Detection and attribution of global mean thermosteric sea level change» E: «Long - term sea level trends: Natural or anthropogenic?»
4) Most of the post-1950s sea level rise is anthropogenic: «Internal Variability Versus Anthropogenic Forcing on Sea Level and Its Components» «The rate of sea - level rise» «Quantifying anthropogenic and natural contributions to thermosteric sea level rise» «Detection and attribution of global mean thermosteric sea level change» «Long - term sea level trends: Natural or anthropogenic?»
«Whilst there are certainly other potential drivers of changes in the climate we know that over the last century we have greatly increased the CO2 concentration in the atmosphere and, through detection and attribution analyses, we know that the rising levels of atmospheric CO2 and other greenhouse gases have driven the rise in global temperature,» King said.
The existence of the multidecadal variability makes climate change detection a challenge, since Global Warming evolves on a similar timescale.
«The application of an automated shoreline detection method to the sandy shorelines thus identified resulted in a global dataset of shoreline change rates for the 33 year period 1984 — 2016.
Expert Team on Climate Change Detection and Indices The joint CCI / CLIVAR / JCOMM Expert Team on Climate Change Detection and Indices develops a number of tools for National Meteorological and Hydrological Service providers, including software toolkits, documentation and other materials to guide users in both the use and calculation of climate indices, as well as guide users in data homogenization, improvement of global coverage and the assessment of climate indices.
An index used in many climate change detection studies is global mean surface temperature, either as estimated from the instrumental record of the last 140 years, or from palaeo - reconstructions.
It could be evenly distributed in the global ocean causing an almost imperceptable rise in its temperature well beyond the margin of detection error or it could be rejected by more efficient means of transport from surface to space or by a change which prevents it from ever reaching the surface in the first place.
