Trump's stance on the environment contradicts thousands of scientists and decades of research, which has linked many observable changes in climate, including rising air and
ocean temperatures, shrinking
glaciers, and widespread melting of snow and ice, to an
increase in greenhouse gas emissions from human activities.

glaciers and ice sheets will melt, and how fast
oceans will rise, as
temperatures increase
The north - south gradient of
increasing glacier retreat was found to show a strong pattern with
ocean temperatures, whereby water is cold in the north - west, and becomes progressively warmer at depths below 100m further south.
Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic
temperatures; melting

ocean acidification; and
increasing atmospheric water vapor.
Numerical computer modelling of the
glacier for these different time periods will help us understand whether this part of the ice sheet is susceptible to rising sea level, warming
oceans or
increased atmospheric
temperatures.
would a plausible physical explanation be that the deep
ocean and ice sheets are still responding somewhat to the post-glacial
temperature increase (eg, T - T0, 0 > 0), but that the faster components of SLR like the surface
oceans and
glaciers were actually responding to the decrease in
temperature since the early Holocene?
That would also imply that (T - T0 (t)-RRB- must be negative during the pre-900 period when SLR = 0... would a plausible physical explanation be that the deep
ocean and ice sheets are still responding somewhat to the post-glacial
temperature increase (eg, T - T0, 0 > 0), but that the faster components of SLR like the surface
oceans and
glaciers were actually responding to the decrease in
temperature since the early Holocene?
These include
increases in heavy downpours, rising
temperature and sea level, rapidly retreating
glaciers, thawing permafrost, lengthening growing seasons, lengthening ice - free seasons in the
ocean and on lakes and rivers, earlier snowmelt, and alterations in river flows.
If one wants to make the connection to global warming for this
glacier, one will need to proof that
ocean temperatures under the ice have
increased.
Among these physical changes are
increases in heavy downpours, rising
temperature and sea level, rapidly retreating
glaciers, thawing permafrost, lengthening growing seasons, lengthening ice - free seasons in the
oceans and on lakes and rivers, earlier snowmelt and alterations in river flows.
«As a coastal city located on the tip of a peninsula, San Francisco is vulnerable to sea level rise, and human activities releasing greenhouse gases into the atmosphere cause
increases in worldwide average
temperature, which contribute to melting of
glaciers and thermal expansion of
ocean water — resulting in rising sea levels,» the ordinance reads.
Whether we look at the steady
increase in global
temperature; the buildup of greenhouse gases in the atmosphere to the highest level in a half - million years; the march of warmest - ever years (9 of the10 hottest on record have occurred since 2000); the dramatic shrinking of mountain
glaciers and Arctic sea ice; the accelerating rise in sea level; or the acidification of our
oceans; the tale told by the evidence is consistent and it is compelling.
The 2009 State of the Climate Report of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate change is real because of rising surface air
temperatures since 1880 over land and the
ocean,
ocean acidification, sea level rise,
glaciers melting, rising specific humidity,
ocean heat content
increasing, sea ice retreating,
glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines of evidence.
But the
temperature increase will reduced
glaciers, and warmed
ocean.
And the pace is only
increasing in recent years as
glaciers melt faster and water
temperatures increase, causing
oceans to expand.
Like how will
increasing ocean temperatures affect
glaciers and coastal communities?
The evidence includes accelerated sea level rise, rising global
temperatures, warming
oceans, declining Arctic ice sheet, worldwide
glaciers retreat,
increase of extreme weather events and
ocean acidification.
That may seem small at first, but over time, especially when combined with other sources of sea level rise such as melting Greenland
glaciers and the expansion of seawater as
ocean temperatures increase, it adds up.
I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant
increase of the global surface and tropospheric
temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global
ocean heat content
increase, Arctic and Antarctic ice decrease, mountain
glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.
Sea levels have been creeping up for the past 50 years, as
glaciers retreat and icecaps melt, and as
oceans expand with
increasing atmospheric
temperatures.
If you are focused on simple thermodynamic reasoning, don't forget about
increased snowfall from warmer
ocean temperatures, that can temporarily (for say a few thousand years)
increase mass balance of the continental
glaciers.
As global
temperature increases, thermal expansion of
ocean water and melting of
glaciers occur.
The evidence comes from direct measurements of rising surface air
temperatures and subsurface
ocean temperatures and, indirectly, from
increases in average global sea levels, retreating
glaciers, and changes in many physical and biological systems.
Heat - trapping greenhouse gases originating mainly from fossil fuel combustion are responsible for the steadily rising global
temperature, the melting of
glaciers and ice caps, the expansion of the
ocean and rise in sea level, the
increase in droughts and subsequent problems of climate refugees, and the
increase in violent storms.
New scientific studies provide a further warning of the
increasing vulnerability of Antarctic
glaciers to faster melting as
temperatures rise in the Southern
Ocean.
«The top of the
glacier is melting away as a result of decades of steadily
increasing air
temperatures, while its underside is compromised by currents carrying warmer
ocean water, and the
glacier is now breaking away into bits and pieces and retreating into deeper ground.»
Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic
temperatures; melting

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an
increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global
temperatures, sea surface
temperatures,
ocean heat content — those will
increase — and ice sheet volumes, tropical
glacier volumes, sea ice extent will decrease.
Global sea level is currently rising as a result of both
ocean thermal expansion and
glacier melt, with each accounting for about half of the observed sea level rise, and each caused by recent
increases in global mean
temperature.
At first glance, sea - level rise is a straightforward phenomenon: As global
temperatures increase,
glaciers melt, pouring additional water into the
oceans.
But to slow sea level
increases — which are caused primarily by melting
glaciers and the expansion of warming
oceans — he said the rate of global
temperature increase must be slowed.
