How carbon is exchanged and recycled continuously between each reservoir of the earth it
- between the pedosphere, biosphere, lithosphere and atmosphere and hydrosphere

# data[].attributes.body
The carbon cycle is the exchange between atmosphere organic matter, environment etc.

# data[].attributes.body
Carbon cycle is the biogeochemcial cycle where carbon is exchanged among different organic matter. Eg. Photosynthesis,   Respiration and burning of fossil fuels

# data[].attributes.body
The carbon cycle is the biogeochemical cycle where carbon is exchanged and distributed in the atmosphere, plants etc. For example a plant uses carbon dioxide for photosynthesis then when it dies becomes plant matter and slowly will decompose and recycle over and over

# data[].attributes.body
Carbon cycle: the exchange of carbon between the atmosphere, terrestrial vegetation, ocean, fossil fuels

# data[].attributes.body
carbon cycle is when CO2 in the air (from industrial emissions, animal respiration) gets photosynthesised by plants. the leaves decay into the soil

# data[].attributes.body
Carbon cycle: the exchange of carbon among the atmosphere, vegetation, soil, ocean, fossil fuels

# data[].attributes.body
carbon cycle is the exchange of CO2 between different mediums; atmosphere, land. For example, vegetation takes in CO2 through the process of photosynthesis.

# data[].attributes.body
the carbon cycle is the exchange of carbon between the atmosphere, organisms, soils, oceans.

# data[].attributes.body
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the different spheres/ in different forms.

# data[].attributes.body
The carbon cycle is the exchange of carbon between soils, atmosphere, vegetation, organisms, oceans

link to climate change: carbon in the atmosphere leads to retaining of heat since IR is absorbed and remitted to earth

Processes:

twice as much carbon in soil, industrialisation increases the release

gases made from combustion of fossil fuels

biological activity - photosynthesis and respiration

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
processes such as P/S ,decomposing , producing energy

-  severe rainstorms and droughts are becoming increasingly common. Changes in rainfall and temperature patterns alter plant and animal behavior

-Large threats to coastal communities as 40% of the worlds population lives in a 100km proximity of the ocean because of rising sea levels this puts these communities at risk
-Melting of sea ice exposes large amounts of the open ocean which is extremely absorbent contrasting from that it was reflective before. This links with the albedo effect as the earth is absorbing more of the suns energy than  before was reflected.

# data[].attributes.body
- There are extreme risks to populations living near coastal regions as they are more prone to large scale flooding. Around 40% of the worlds population lives within 100 km of the ocean, this puts livelihoods and infrastructure at risk.

# data[].attributes.body
- loss of sea ice exposes dark open waters, shifting the ocean surface from highly reflective to highly absorbant. The Earth would absorb more of the Sun's energy.
- loss of sea ice accelerates warming, which threatens animals and the livelihood of indigenous peoples and their way of living.
-  if there is a rise in the sea levels, there would be a salt water intrusion into the groundwater drinking supplies and contaminating irrigation supplies
- 40% of the world's population live in coastal communities, the rise in sea levels would endanger them.

# data[].attributes.body
saltwater intrusion - saltwater may contaminate  drinking supplies, irrigation supplies, or overrunning agricultural fields. Low lying areas where a majority of people live are particularly at risk

# data[].attributes.body
- The ocean has absorbed so much heat(about 20 times as much as the atmosphere over the past half-century) that some models suggest that it is likely to warm the air another degree Fahrenheit (0.55° Celsius) worldwide over the coming decades
-  As more CO2 from the atmosphere dissolves into the ocean making the water more acidic & reducing the concentration of carbonate ions in surface ocean water by 10 per cent, compared with pre-industrial levels. This is significant because coral reefs and shelled marine organisms need carbonate ions to form the lime or calcium carbonate that composes their skeletons and shells -> loss of a protective barrier

# data[].attributes.body
Sealevel rise can cause salt intrusion into groundwater supplies
- this would cause contaminated irrigation and the overrunning of agriculture fields

Natural protections like barrier islands, beaches and sand  are effected and retreat. There are rises in erosion of stranded beaches, wetlands and engineered structures

# data[].attributes.body
- Acidification of ocean due to the fact that climate change has affected the ability for coral reefs and shelled organisms to form skeleton and shells. Acidification occurs when the ocean absorbs excess CO2 from the atmosphere, ultimately making the water more acidic.

-threats to coastal communities --> 40% of the world's pop lives within 100km of the ocean --> puts millions of lives and billions of dollars' worth of property and infrastructure at risk
-security concerns from new shipping routes --> arctic countries vie for access to valuable resources or feel compelled to protect these natural and commercial resources

Reduced yields: The productivity of crops and livestock, including milk yields, may decline because of high temperatures and drought-related stress.

# data[].attributes.body
- Some 40% of the worlds population lives within 100km of the ocean. This puts many people at risk to rising sea levels, with potential risk to property and infrastructure and forced migration of individuals.
- Saltwater intrusion: saltwater intrudes into groundwater drinking supplies. This puts further stress on water supplies and could lead to conflicts arising.

# data[].attributes.body
- increase spread of disease  (vector), warmer oceans and other surface waters may also mean severe cholera outbreaks and harmful bacteria in certain types of seafood
- forced migrations and extinctions (plants and animals) --> to higher altitudes and latitudes because too hot to survive in lower alititudes
