Industrial emissions of greenhouse gases that affect the climate. Green carbon Carbon stored in terrestrial ecosystems e. Black carbon Formed through incomplete combustion of fuels and may be significantly reduced if clean burning technologies are employed. But a mitigation approach needs to consider all these forms of carbon they note, not just one or two:
Other examples Climate change impacts on biodiversity in the Arctic The Arctic, Antarctic and high latitudes have had the highest rates of warming, and this trend is projected to continue, as the above-mentioned Global Biodiversity Outlook 3 notes p.
In the Arctic, it is not just a reduction in the extent of sea ice, but its thickness and age. Less ice means less reflective surface meaning more rapid melting. The polar bear depends on sea ice. Image source In terms of biodiversity, the prospect of ice-free summers in the Arctic Ocean implies the loss of an entire biomethe Global Biodiversity Outlook notes p.
The iconic polar bear at the top of that food chain is therefore not the only species at risk even though it may get more media attention. Note, the ice in the Arctic does thaw and refreeze each year, but it is that pattern which has changed a lot in recent years as shown by this graph: The extent of floating sea ice in the Arctic Ocean, as measured at its annual minimum in September, showed a steady decline between and National Snow and Ice Data Center, graph compiled by Secretariat of the Convention on Biological Diversity Global Biodiversity Outlook 3, May It is also important to note that loss of sea ice has implications on biodiversity beyond the Arctic, as the Global Biodiversity Outlook report also summarizes: Bright white ice reflects sunlight.
When it is replaced by darker water, the ocean and the air heat much faster, a feedback that accelerates ice melt and heating of surface air inland, with resultant loss of tundra. Less sea ice leads to changes in seawater temperature and salinity, leading to changes in primary productivity and species composition of plankton and fish, as well as large-scale changes in ocean circulation, affecting biodiversity well beyond the Arctic.
However, most of the warming is going into the oceans where a lot of ecosystem changes are also occurring: John Cook, Infographic on where global warming is goingSkepticalScience. Indeed, as this chart also shows, the warming in the oceans has been occurring for quite some time:Latest news and information from the World Bank and its development work on Climate Change.
Access facts, statistics, project information, development research from experts and latest news about Climate Change. Temperature rise due to climate change may radically damage the global economy and slow growth in the coming decades if nothing is done to slow the pace of warming, according to new research.
Scientific opinion on climate change is a judgment of scientists regarding the degree to which global warming is occurring, its likely causes, and its probable consequences.. A related—but not identical—term, "scientific consensus on climate change," is the prevailing view on climate change within the scientific community.
The consensus is that: Earth's climate . Climate Central bridges the scientific community and the public, providing clear information to help people make sound decisions about the climate. By , climate change impacts such as storms and drought could displace up to million people worldwide.
Nations should recognize 'climate migrants' and make plans for aiding and resettling them. Scientific opinion on climate change is a judgment of scientists regarding the degree to which global warming is occurring, its likely causes, and its probable consequences.. A related—but not identical—term, "scientific consensus on climate change," is the prevailing view on climate change within the scientific community.
The consensus is that: Earth's climate has warmed significantly.
