Sentences with phrase «local sea level trends»

Not exact matches

Beyond honing communications skills, participants said while the discussions often started off with broad trends in climate science, invariably the exchanges shifted to specific local issues such as wildfires, ozone levels, crop rotations, sea level rise, droughts and air quality.

This decreasing trend in local gravity is sufficient to counteract all other sources of local sea - level rise.

Note that the variation in sea level due to ENSO is only a few mm, really small compared to both the longer - term anthropogenic trend and to the local variations in sea level in the Pacific which can be even decimetres in places.

However the general sea level rise trend has a lot of local variation.

The biggest difficulty in using tidal gauges to study global sea level trends is separating local changes from global changes.

This will have introduced an artificial «sea level rise» trend into the tidal gauge records for those areas, which is actually due to the local land subsiding.

However, as we have seen throughout this section, the tidal gauge estimates the IPCC used to estimate global sea level trends are contaminated by local trends, such as tectonic activity, post-glacial rebound... and the coastal subsidence that Syvitski et al. identified!

Over the long - term, melting of the West Antarctic Ice Sheet could yield as much as 10 to 14 feet of global average sea level rise, with local sea level rise varying considerably depending on land elevation trends, ocean currents and other factors.

In order to use tidal gauges to reliably estimate global sea level changes, researchers have to successfully separate the components of shifting land heights and local sea level variability from any global trends.

The map of regional mean sea level trends provides an overview of variations in the rates of relative local mean sea level observed at long - term tide stations (based on a minimum of 30 years of data in order to account for long - term sea level variations and reduce errors in computing sea level trends based on monthly mean sea level).

Stations illustrated with negative trends (blue - to - purple) are experiencing global sea level rise and a greater vertical rise in the local land, causing an apparent decrease in relative sea level.

Stations illustrated with positive sea level trends (yellow - to - red) are experiencing both global sea level rise, and lowering or sinking of the local land, causing an apparently exaggerated rate of relative sea level rise.

Choice of GIA correction is critical in the trends for the local and regional sea levels, introducing up to 8 mm · yr − 1 uncertainties for individual tide gauge records, up to 2 mm · yr − 1 for regional curves and up to 0.3 — 0.6 mm · yr − 1 in global sea level reconstruction.

However, this is complicated by non-tidal, short - term, local sea - level variability that is orders of magnitude greater than the trend.»

He continually confuses global, regional, and local temperature trends, which may differ considerably; he mischaracterizes the results of a poll that was undertaken to determine scientists» views on global warming; and he mistakenly asserts that the sea level has not risen significantly, when it has.

Note that these trends may include a component of subsidence / uplift of the islands themselves and so are the numbers most relevant for local planning (not eustatic sea level change).
