Ocean Acidification (Carbon Cycle)

Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. The main cause of ocean acidification is the burning of fossil fuels. Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. Many factors contribute to rising carbon dioxide levels. Currently, the burning of fossil fuels such as coal, oil and gas for human industry is one of the major causes. Because of hu

Water Supply and Demand

The growing mismatch between water supply and demand has led to a global pattern of water stress (below 1,700 m³ per person) and water scarcity (below 1000m³ per person). The increase in supply was due to meet the increase in demand from the three main users of water: agriculture; industry; and domestic. Agriculture has the largest demand for water and is growing at the fastest rate. This is because the amount of cropland irrigated has increased at a faster rate than the worl

Energy Consumption and Energy Mixes (Energy Security)

Energy consumption refers to ALL the energy used to perform an action, manufacture something or simply inhabit a building. Let’s look at a few examples: In a factory, total energy consumption can be measured by looking at how much energy a production process consumes, for example, by making car parts. Energy consumption is influenced by many social and economic factors and drivers. Especially in the less developed countries, the tremendous increase of the population as well as the expected signi

Coastal Flooding (Coastal Landscapes and Change)

Coastal flooding is a sudden and abrupt inundation of a coastal environment caused by a short-term increase in water level due to a storm surge and extreme tides. The magnitude and extension depend on the coastal topography, storm surge conditions and broader bathymetry of the coastal area. When a coastal process - such as waves, tides, storm surge, or heavy rainfall from coastal storms - produces that flood, it is called a coastal flood. Other types include moderate and major floods that can be

Consequences of Coastal Recession and Flooding

As global sea level rises, the action of waves at higher elevations increases the likelihood for extensive coastal erosion. Already, coastal erosion costs roughly $500 million per year for coastal property loss, including damage to structures and loss of land. Climate change will increase people's exposure to coastal flooding, which can lead to drowning, injuries, diarrhea or stomach illnesses associated with contaminated water, and mental health consequences. In a Louisiana study, a Louisiana S

Energy Resource Access and Consumption

Access to electricity reduces poverty, increases opportunity, and improves health, productivity and living standards. Electricity is an essential part of innovation, progress and life. 13% of the world do not have access to electricity. Electricity is crucial for poverty alleviation, economic growth and improved living standards. Measuring the share of people with electricity access is therefore an important social and economic indicator. 40% of the world do not have access to clean fuels for co

Alternative Energy (Biofuels, Hydrogen, CCS)

Biofuels use biological matter (animal and plant) to create energy. Biofuel is renewable when plants are used because, of course, plants can always be grown. However, they do require dedicated machinery for extraction, which can indirectly contribute to increased emissions even if biofuels themselves don’t. Biofuels are increasingly being adopted, particularly in the US. Carbon capture and storage (CCS) is the process of capturing and storing carbon dioxide (CO2) before it is released into the a

Development: Contrasting Views

Improvements in environmental quality, health, life expectancy and human rights are seen by some (Hans Rosling) as more significant goals for development whilst economic growth is often the best means for achieving them. Economic growth is needed to build infrastructure, raise incomes to pay for medicine and education and develop journalism for human development to increase. Education is central to economic development (human capital) and to the understanding and assertion o

Global Warming and Oceans (Climate Change Impacts)

The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals. Rising ocean temperatures also affect the benefits humans derive from the ocean – threatening food security, increasing the prevalence of diseases and causing more extreme weather events and the loss of coastal prot

Coastal Flooding Examples

What causes Bangladesh to flood? Lots of low-lying land, melt water from the Himalayas, heavy deforestation and heavy monsoon rains. In 2007, Bangladesh's annual monsoon started with unusually heavy rain, intensified by a storm from the Bay of Bengal on June 9-10, 2007. In addition to the floods, the rains triggered devastating landslides in the deforested hills on which the city is built. How is Bangladesh impacted by flooding? Erosion of chars (islands) by flooding rivers causes landlessness a

Global Warming (Impacts of Climate Change)

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. “Climate change” and “global warming” are often used interchangeably but have distinct meanings. Similarly, the terms "weather" and "climate" are sometimes confused, though they refer to events with broadly different timescales. “Global w

Savanna Ecological Change (Serengeti, Pressures, Responses, Threats)

The Serengeti is a vast ecosystem in east-central Africa. It covers 12,000 square miles, giving rise to its name, which is derived from the Maasai language and means "endless plains." This region of Africa is located in north Tanzania and extends to southwestern Kenya. The Serengeti is best known for its huge herds of plains animals, especially wildebeests, gazelles, and zebras, and it is the only place in Africa where vast land-animal migrations still take place. The Maasai people of the Sereng

Water Security and Climate Change

There is wide scale concern about the security of water supplies because climate changes are changing patterns and creating uncertainty. Climate change resulting from short term oscillations ( ENSO cycles) and global warming increase the uncertainty in the system; this causes concerns over the future of water supplies as well as future projections of drought and flood risk. One of the problems with this forecasting of possible changes to the hydrological cycle is distinguish

The Impacts of Climate Change on the Planet

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns. Impacts that scientist

Causes of Flooding

A flood is an overflow of water that submerges land that is usually dry. Floods are an area of study in the discipline of hydrology. They are the most common and widespread natural severe weather event. Flooding can occur anywhere, including both coastal and inland locations. There are 5 types of flood according to the National Severe Storms Laboratory: river flood; coastal flood; storm surge; inland flooding; and flash flood. The likelihood of flooding is also inc

The Changing Climate

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and

Population and Resources (Carrying Capacity, Ecological Footprints, PRP Model)

The magnitude of the threat to the ecosystem is linked to human population size and resource use per person. Resource use, waste production and environmental degradation are accelerated by population growth. Increased population translates to increased demand for food and space for settlement. Population growth also lead to over exploitation of resources like forests, fish, minerals and even water. What are the effects of overpopulation? More people means an increased demand for food, water, hou

Rapid Coastal Recession (Coastal Landscapes and Change)

Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and/or sands along the coast. Sea level rise will cause an increase in coastal erosion and the human response will be critical. Waves are the main cause of coastal erosion. The higher the wave energy, the higher the rate of erosion (all other things being equal). Any or all of these factors can combine to make steeper, higher-energy waves. Human activity ca
