Human Impact on Climate Change

Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner. With the power of video chat technology, we can connect scientists, policymakers, and concerned individuals from around the world, enabling real-time communication, information exchange, and coordinated efforts to mitigate the impacts of climate change.

Human Role in Global Warming

Overfishing - More Fish in the Sea, Less Climate Change

Fish is one of humans main sources of protein and a lot of the world now rely on this industry. Due to the amount of people buying and consuming fish, there is now a reduced amount of marine life. Overfishing has also caused a lack of diversity within the ocean.

Industrialization Leading to Climate Change

Global warming is defined as "a consistent increase in the earth's average temperature denoted by increasing global surface temperatures caused or influenced by continuous emissions of greenhouse gases, with over 90% of the air polluted by carbon dioxide and CFCs such as methane and nitrous oxide, as well as other air pollutants.

Impact of Agriculture on Climate Change

Besides its contribution to global warming, farming has other detrimental effects on the environment. Agriculture is often the reason for deforestation and a change in land use, from natural ecosystems that take up and store carbon dioxide (CO2) from the atmosphere, to farmland. These activities cannot be viewed independently.

Transportation and Climate Change

Aircraft are the third-largest source of greenhouse gas pollution from the U.S. transportation sector and account for approximately 9 percent of U.S. transportation And the emissions from domestic aviation are increasing at an alarming rate 17 percent since 1990. Ships, besides releasing almost 3% of the world’s CO2, are a main source of nitrous oxide and black carbon (soot).
