Similar negative effects occur with worsening air pollution — higher
levels of ground -
level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising

coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires,
which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

As you are aware
sea level rise also has the effect of moving the grounding line proximally,

For example, as a result of ice melting on land, such as from glaciers and ice sheets, as well as thermal expansion of the ocean, we have seen
sea level rise 3.4 millimeters per year from 1993 - 2015,
which puts
coastal communities at risk of flooding and infrastructure damage.
The ice sheet is the focus of scientific research because its fate has huge implications for global

which are already rising as ice sheets melt and the ocean warms, exposing
coastal locations to greater damage from storm surge - related flooding.
Scientists are also confident that heating of the deep oceans and melting of land ice will lead to continued

The cities» lawsuits allege — supported by modern climate science — that major oil and natural gas companies contribute substantially to global warming by extracting and using fossil fuels,

coastal communities.
It would also enable more of the fossil fuel pollution driving climate change,

sea level anomaly creates an along - shelf geostrophic
coastal current anomaly,
which is particularly strong on the western side of the Peninsula.
But there are two climate - related issues that we need to consider now: rising

which is already affecting the magnitude of storm surges,
which in practice do much of the damage in hurricanes and other
coastal storms), and projections that the incidence of very intense hurricanes should increase in the 100 - year time scale.
Many

which lies below
sea level.
The modern climate alarmism fears of the soon - to - be flooding of
coastal regions,
which would unleash a horde of climate refugees, is entirely without scientific merit, per the modern dataset records and the expert research done on the pre-history
sea levels and trends.
The rising
sea level could pose a major threat to
coastal cities — some of
which are already affected by higher tides.
The goal of the post is to contribute to improved scenarios of
sea -
level rise,
which is an important aspect of climate change, with large
coastal impacts.
In this context, we develop national projections of the urban and non-urban
coastal population on the basis of four environmental and socio - economic scenarios
which account for
sea -
level rise (for the flood plain analysis), population distribution, trends in urbanisation and
coastal population growth.
Coastal Flooding to Increase in Less Obvious Areas In case you need a closer to home example (and one note as obvious as the Mississippi Delta...): An assessment of the impact of
sea level rise on New York City showed that by 2080
coastal flooding
which historically had been experienced every 10 years, would now occur every 3, and the statistical «once in a century» storm would more likely become the «once every 10 - 35 years» storm.
My own goal is to have readers (and maybe even but not necessarily Graeme) understand the invalidity of his argument asserting that (essentially) one
sea level time series observation at one
coastal location that (allegedly) doesn't show much change in several decades does not imply that the
sea level changes have been the same at all other
coastal locations (give or take 100 mm)-
which implies that any observed variations exceeding this
level in
sea level rise at different locations around the world are «not real» and hence
sea level rise due to global warming isn't anything to worry about.
In July, the Arctic Dipole Anomaly (DA) pattern that was dominant in June (
which promotes clear skies, warm air temperatures, and winds that push ice away from
coastal areas and encourages melt) was replaced by low
sea level pressure (SLP) over the Arctic Ocean, leading to ice divergence (ice extent «spreading out») and cooler temperatures.
Sea level rise is likely to devastate infrastructure along the coastlines, but it will also have a significant impact on freshwater and the economies that are tied to
coastal infrastructure,
which go far inland in many countries.
Even without epic storms, Horton said climate - related
sea level increases can cause massive problems for
coastal areas because it increases frequent flooding,
which causes erosion, contaminates drinking water supplies and aquifers, damages farmland and decreases habitat for fisheries, wildlife and plants.
