Global warming occurs naturally but is now exacerbated by human activities like industrialization. The greenhouse effect involves gases in the atmosphere trapping heat from the sun, warming the planet. Increased greenhouse gases from human activities have raised the Earth's surface temperature to new highs and caused severe weather events. If emissions are not reduced, scientists warn of even greater temperature rises, more extreme storms, floods and droughts, and small island nations being submerged due to sea level rise from melting ice sheets and thermal expansion of oceans. International agreements like the Kyoto Protocol have aimed to reduce emissions but more action is still needed to prevent destructive climate change impacts.

The document discusses human impacts on the environment through climate change and the greenhouse effect. It defines key terms like climate change, greenhouse gases, and global warming. It describes the composition of the atmosphere and the major sources of greenhouse gases like carbon dioxide and methane from activities like burning fossil fuels, agriculture, and decomposition. The greenhouse effect keeps temperatures warm for life but an enhanced effect due to human-caused emissions is causing global warming with impacts like rising seas and stronger heat waves. Reducing climate change requires changes in individual behavior and reducing greenhouse gas emissions.
Climate change
The document defines climate change as changes in weather patterns over time that are primarily driven by rising carbon dioxide levels from burning fossil fuels. It lists the main causes as greenhouse gas emissions from industries, transportation, and electricity production. The effects discussed include changes in weather patterns like more intense hurricanes, droughts, and rainstorms as well as impacts to health, wildlife, glaciers and sea levels. Potential solutions proposed are developing renewable energies, reducing transportation emissions, international agreements like the Kyoto Protocol, and increasing public awareness of the issue.

This document discusses climate change and its implications. It begins by defining weather and climate, noting that climate refers to long-term atmospheric conditions over 100 years. It then explains that climate change represents a significant shift in weather patterns and has occurred many times over 100,000 years due to various external and internal causes. Some key points made include that greenhouse gases trap heat in the atmosphere and have warmed the planet by around 15 degrees Celsius, climate change is affecting lives through rising seas and temperatures and more extreme weather, and actions need to be taken to mitigate climate change through renewable energy and carbon capture.
Global warming and_the_greenhouse_effect
This document discusses global warming and the greenhouse effect from Ms. Kopchick's Earth Science class. It defines the greenhouse effect and how an increase in greenhouse gases leads to global warming. It outlines the major greenhouse gases like carbon dioxide, methane, and nitrous oxide and their sources. The effects of global warming include rising sea levels, more extreme weather, habitat damage, and species extinction. The document discusses potential solutions to slow global warming like transitioning to renewable energy, reducing deforestation, and individual actions like using energy efficient appliances and compact fluorescent light bulbs.
Global warming
Global warming is causing significant changes to the Earth's climate. Glaciers and ice sheets are melting, sea levels are rising, and extreme weather events are becoming more common. The scientific consensus is that human activities, such as burning fossil fuels and deforestation, have increased greenhouse gas levels and caused most of the warming observed since the mid-20th century. As temperatures continue to rise, the impacts on the environment, plants and animals, weather patterns, and human society will intensify and become more costly. Individual actions to reduce energy use and greenhouse gas emissions can help address the problem.
