Types of Pollution Accidental Disasters The Deepwater Horizon Spill that occurred in in the Gulf of Mexico in just one example of an extreme accident that killed people and aquatic life. The spill impacted environmental and economical sectors and even reached the shorelines.
Learn about the causes of climate change and how you can reduce its threat. Share Climate change Climate change is the rise in average surface temperatures on Earth, mostly due to the burning of fossil fuels.
Say Hello to the New Face of Climate Change Climate change, also called global warming, refers to the rise in average surface temperatures on Earth.
An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.
Is climate change real? There is broad-based agreement within the scientific community that climate change is real. Environmental Protection Agency, the National Aeronautics and Space Administration, and the National Oceanic and Atmospheric Administration concur that climate change is indeed occurring and is almost certainly due to human activity.
What are the causes of climate change? The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide. Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change.
Today it is at about ppm, a level not reached in more thanyears. Increased burning of fossil fuels contributes to climate change.
Rising sea levels due to the melting of the polar ice caps again, caused by climate change contribute to greater storm damage; warming ocean temperatures are associated with stronger and more frequent storms; additional rainfall, particularly during severe weather events, leads to flooding and other damage; an increase in the incidence and severity of wildfires threatens habitats, homes, and lives; and heat waves contribute to human deaths and other consequences.
While the latter is generally true, decades of data and analysis support the reality of climate change—and the human factor in this process.
In any case, economists agree that acting to reduce fossil fuel emissions would be far less expensive than dealing with the consequences of not doing so. What flashcards would you like to see?

Causes of Climate Change. The climate changes when the total amount of energy in the Earth’s atmosphere changes. The energy changes spread out around the globe upsetting climate processes. Statement on climate change from 18 scientific associations "Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.".
Shale gas extraction raises environmental concerns in relation to: carbon dioxide (CO 2) and methane (CH 4) emissions, particularly the potential for increased fugitive CH 4 emissions during drilling compared with drilling for conventional gas; the volumes of water and the chemicals used in fracking and their subsequent disposal.
Latest environmental news, features and updates. Pictures, video and more. 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 .
