Antarctic Climate & Ecosystems. Antarctica and the South ern Ocean influence both the regional and global climate in profound ways.
These vast areas will experience significant change as the world warms, and in turn those changes will impact on the global climate. Polar Discovery.

In summer they use photosynthesis to grow, and multiply into huge populations. Young (juvenile) krill that were collected in a net. A curious Emperor penguin approaches a technician.

Located on the eastern shore of Australia’s tropical north, Shipton’s Flat is home to Marilyn, a Kuku Nyungkal Aboriginal woman, and her family.
She has been living here the ancestral way — far removed from the services and conveniences of modern life. Like her ancestors before her, Marilyn walks through the Nyungkal bubu, the Nyungkal’s country, acknowledging and conversing with the spirit beings around her. She greets the spirit of the flowing stream that provides her family with freshwater, the spirits of her mother, father and grandparents that cared for the country before her, the spirits of her ancestors that have been formed into rocks, and the spirits of the trees and animal life around her that lend shade and sustenance.
A change in the weather Marilyn has observed that the seasons are getting hotter. Marilyn feels that the “country is transforming, food is disappearing. What does it mean? “There will be nothing left because it is getting hotter,” Marilyn worries. What should we do? Parks and Wildlife Commission NT.

We connect to it, we're a part of it. Our Country is our home, and we know all the sites and all the features, our rocks, our trees, our hills. We come up with our Country. We come up with it and feel it so strongly.

Introduction Many places on Earth share similar climatic conditions despite being found in geographically different areas.
As a result of natural selection, comparable ecosystems have developed in these separated areas. Scientists call these major ecosystem types biomes. Primary production. Global oceanic and terrestrial photoautotroph abundance, from September 1997 to August 2000.
As an estimate of autotroph biomass, it is only a rough indicator of primary production potential, and not an actual estimate of it. Provided by the SeaWiFS Project, NASA/Goddard Space Flight Center and ORBIMAGE. The maps above show Earth's monthly net primary productivity from February 2000 to December 2013. The data come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Values range from near 0 grams of carbon per square meter per day (tan) to 6.5 grams per square meter per day (dark green). Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. Overview Primary production is the production of chemical energy in organic compounds by living organisms.
CO2 + H2O + light Gross primary production and net primary production NPP = GPP - respiration [by plants] Terrestrial production Light Marine Education Society of Australasia. Climate change may modify half Earth's plants. Ecologically sensitive 'hotspots' include regions in the Himalayas and the Tibetan Plateau, eastern equatorial Africa, the Mediterranean region, and Madagascar, where this flame tree grows.
Credit: Veer Images PASADENA: By 2100, global climate change will modify plant communities covering almost half of Earth’s land surface. Climate change will also drive the conversion of nearly 40% of land-based ecosystems from one major ecological community type – such as forest, grassland or tundra – toward another, according to a new NASA and university computer modelling study. Atlas of Living Australia. What is ‘citizen science’?
Climate Change and Citizen Science. Climate LiteracyAbout Teaching Climate Literacy Environmental observations are the foundation for understanding the climate system.
From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.
