SEA LEVEL RISE: San Francisco Bay Area MUD 692 l Kevin Kellogg l FALL 2012 l Utkarsh Kumar The Theory: Coastal cities need preservation and restoration‚ not development to tackle the issues of Sea Level Rise. “We basically have three choices: mitigation‚ adaptation‚ and suffering‚” said John Holdren‚ the president of the American Association for the Advancement of Science and an energy and climate expert at Harvard. “We’re going to do some of each. The question is what the mix is

Rising Sea Levels: The Impact Introduction Gradual increase in temperature known as climate change is causing icebergs to melt and therefore‚ increasing sea levels‚ this is basic known fact but what might not be as clear is the effect of rising sea levels on the environment. Amongst the vast variety of issues to do with climate change‚ its impact on the ocean stood out for me. After I researched the impact of climate change on the ocean‚ I found that the topic was too broad; therefore I decided

Environmental Threats Global Problems Sea Level Rising At present‚ sea levels around the world are rising. Current sea level rise potentially impacts human populations and the natural environment. Global average sea level rose at an average rate of around 1.7 ± 0.3 mm per year over 1950 to 2009 and at a satellite-measured average rate of about 3.3 ± 0.4 mm per year from 1993 to 2009‚[01] an increase on earlier estimates.[02] Climate change Destructive sudden heavy rains‚ intense tropical

is a problem ancient societies before us have faced and survived. For instance‚ in Australia‚ during the Holocene period‚ the changing climate (the end of an Ice Age) brought on a rise in sea level‚ which forced the human population to migrate to other areas—areas often occupied by others. Due to the rising sea levels‚ several groups also found themselves stranded on isolated islands; an isolation that only the strong and the creative survived. In Tasmania‚ people ceased eating fish‚

Impacts of Sea Level Rise There are two main reasons why sea levels are rising‚ firstly as air temperatures rise (due to climate change) the water in the oceans is warmed and expands. This process is called thermal expansion. The second reason being that as ice sheets and glaciers melt‚ they increase the amount of water in the oceans. Both of which are rather straightforward. Scientists have shown that in the past there have been periods of significant sea level change due to natural factors. However

plugged even if we are not using it‚ even this simple act is using energy that is why we should always unplug electronics every time we are finish using them. They said that the sea helps us to lessen the CO2 or the Greenhouse Gases‚ but because there are many of them they could not cope and the result is that even the sea becomes warmer. They also gave some examples of the signs‚ like Coral Bleaching‚ the case that is currently happening in El Nido‚ Palawan‚ and as a result a lot of fishes lost

Glaciers and Risen Sea Level The article‚ Antarctic glacier melt is unstoppable‚ tells us that glaciers located in the West Antarctic have entered the state of extreme meltdown. Researchers have collected twenty years of data imagery of several glaciers in the Antarctic which show the ice disintegrating into the water. Consequently‚ scientists predict this will cause the increase sea levels to increase. So as the article states‚ it is obvious that as for now the rise of sea water cannot be controlled

rate at the water level is rising has dramatically increased. The rise in sea level has been primarily climate change driven. Many natural and human activities such as the burning of fossil fuels has created released large amounts of greenhouse gasses into the atmosphere. These emissions have caused the Earth’s surface temperature to rise‚ creating Thermal Expansion (where the water droplets expand due to heat) as well as the melting of ice sheets. The unexpected rise in sea level has caused catastrophic

The Effects of Sea-Level Rise on Coastal Salt Marshes and their Associated Ecosystem Services Katelyn M. Nyberg Introduction Climate Change The Intergovernmental Panel of Climate Change (IPCC) has observed an increase of 0.19 meters of global mean sea-level rise from 1901 to 2010‚ with “about 70% of the coastlines worldwide projected to experience a sea level change within ±20% of the global mean” (IPCC 2014). Dramatic increases in sea-level are produced by increasing temperatures which cause glaciers
