Radar altimeters are used to measure very precisely the height of the ice above the sea surface, from which its thickness can be derived. The CCI Sea Ice team has developed monthly sea ice thickness maps using radar altimeter data from ESA’s Envisat mission from 2002 to 2012, and from CryoSat, launched in 2010. The CCI Ice Sheet team also uses these satellite altimeters to measure the thickness of the Greenland and Antarctic Ice Sheets.\r\n \r\nThe retrieval of sea ice thickness from altimetry works well only in the winter months, and only for relatively thick ice. The team is also looking at the novel use of data from ESA’s Soil Moisture and Ocean Salinity satellite (SMOS) to measure the thickness of thin ice, and at the new capabilities offered by future ESA satellites such as CRISTAL and CIMR. \r\n\r\nThe observed Arctic sea ice loss has been found to directly follow humanity’s cumulative carbon dioxide emissions: 3 m2 of ice are lost in September for every tonne of carbon dioxide we add to the atmosphere. That’s about the emission per passenger on a single trans-Atlantic flight. Climate models using the CCI data as an input show that, at current emission rates, it is likely that the Arctic Ocean will be largely ice-free in the summer before 2050.",

The energy exchange between ocean and atmosphere during these events is revealed by a dip in the sea surface temperature in the wake of large hurricanes. \r\n\r\n## Climate Indicators\r\nWhile the atmosphere can quickly move energy around the planet in weather systems, the ocean’s much greater capacity to store heat makes it a more stable indicator of longer-term climate trends. The rise in global average air temperature slowed down in the first decade of this century, causing some to question global warming, but the slowdown has proved temporary, with air temperature rising quickly again since 2012.

As the warm water builds up so does cloud cover, due to the increased evaporation of sea water. \r\n\r\n## La Niña\r\nWhen El Niño ends, the cold water sometimes returns stronger than ever, clearing a gap in the clouds as the local climate enters its cool phase – La Niña. These changes to ocean temperature and evaporation over the Pacific lead to changes in rainfall trends across the world. Certain areas can experience wetter or drier conditions than normal, which can lead to more flash floods, drought or wild fires.\r\n\r\nThere are periodic ocean-atmosphere disturbances elsewhere in the world, such as the Indian Ocean Dipole and the North Atlantic Oscillation.",

       "text": "## From Ocean Colour to Carbon Flux\r\n\r\nOne example of how satellite data have been used to improve climate models is provided by the CCI Ocean Colour team’s measurements of chlorophyll concentration. Variations in the colour of the ocean allow us to map the distribution of phytoplankton around the world. These tiny marine organisms contain chlorophyll, just like plants on land, and are linked to key climate processes including the removal of carbon dioxide from the atmosphere and the release of atmospheric aerosols that influence cloud cover.\r\n\r\nWhen the UK Met Office incorporated satellite-observed chlorophyll concentration in their ocean-biogeochemical model, it led to marked improvements in the how the model represented seasonal variations of phytoplankton and its distribution in the deeper parts of the ocean. The team also used the data to better model the exchange of carbon dioxide between the atmosphere and ocean. Comparing the outputs with a set of independent observations of sea surface carbon dioxide not only showed the model provided a better representation of the carbon cycle in some areas but also highlighted where the model needs to be improved.\r\n \r\nIt is important to get this right because it helps us understand how the way the ocean absorbs and releases carbon might change as a result of different amounts and patterns of warming. At the moment, the ocean is an important sink for carbon emissions from human activities, so knowing how it may respond in the future is critical.",

       "text": "## Responding to Change\r\n\r\nWhen a habitat changes, animals and plants may find that their adaptations are not helpful – or even actively disadvantage them – in the new environment and be forced to move elsewhere in order to survive. Pigeons, foxes and, of course, humans are among the species that have adapted to survive in cities. But individual populations of other species that were more specialised, or have been driven into areas where they face greater competition, have become extinct as a result of increased urbanisation or the extension of agriculture into previously wild areas.\r\n\r\nConversely, changing climate is increasing the range of some species, allowing them to thrive in places that were previously inhospitable to them, or changing their habitats in ways that allow the population to boom. This is not always good news for everyone. For example, several years of drought and mild winters in the 2000s allowed the mountain pine beetle to extend its range from Western North America east across the Rocky Mountains, resulting in extensive damage to commercial and natural forests that had previously been free from this pest.\r\n\r\n## Protected Areas\r\n\r\nAn ecosystem with a high level of biodiversity is likely to be more resilient and be able to survive sudden changes. But if all the animals in a food web are ultimately dependent on a single type of plant, then the entire ecosystem may collapse if that plant is affected by disease or extreme weather.\r\n\r\nNational parks and other conservation areas protect a range of habitats from further development or exploitation while, in some of the best cases, continuing to support local people.  Where habitats are becoming fragmented, through, for example, deforestation or damming rivers, wildlife corridors can provide a safe route between areas for wider ranging or slower moving species, such as plants.",

Understanding climate gives us an insight into one of the drivers of ecosystem change and so how we might preserve vulnerable biomes and biodiversity. Land cover and biomass are directly related to the population of a habitat, and are both ECVs that can be monitored from space using satellites. \r\n\r\nOther ECVs also determine whether a certain habitat can thrive. On land, these include land surface temperature and soil moisture. Sea surface temperature and ocean colour are useful measures for monitoring the oceans. ESA’s Climate Change Initiative has used satellite observations to produce records of ECVs that cover the whole world and stretch back more than thirty years. Having a reliable record of these factors, and an accurate understanding of how they are currently changing, helps us make responsible decisions, taking account of the impact they will have on the planet – and all its inhabitants – in the future.",
