Good atmospheric ozone is found mainly in the stratosphere, where it protects the Earth from harmful ultraviolet radiation by absorbing it. Bad atmospheric ozone is primarily found in the troposphere, where it is a harmful pollutant that can cause respiratory problems and contribute to the formation of smog. While good atmospheric ozone is naturally occurring and necessary for life, bad atmospheric ozone is created by human activities such as burning fossil fuels and certain chemical reactions in the presence of sunlight.
In 3-5 sentences, analyze potential impacts of oceans on human populations as the result of climate change in the current century.
Climate change is altering oceans in ways that can have serious impacts on human populations, including rising sea levels that threaten coastal communities; changes in ocean currents and temperatures that could shift fisheries and food chains, leading to food insecurity and economic losses; and ocean acidification that can harm marine life and disrupt ecosystems. As temperatures rise, there is also a risk of more intense storms and other extreme weather events that could damage coastal infrastructure and leave many communities vulnerable to displacement and other social and economic impacts. Addressing these challenges will require an urgent and coordinated response from governments, communities, and stakeholders worldwide.
Identify and analyze the way fossil fuel combustion ahs changed the composition of earth's atmosphere, and the way this change has affected climate.
Fossil fuel combustion has dramatically altered the make-up of Earth's atmosphere by increasing the concentrations of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. These gases trap heat from the Sun that would otherwise radiate back into space, causing a phenomenon known as the greenhouse effect that has led to global warming and climate change. Specifically, increased carbon dioxide concentrations in the atmosphere have caused the Earth's surface temperature to rise, resulting in sea level rises, melting ice caps, more frequent and intense heat waves; changes in rainfall patterns and an increase in the number of extreme weather events, including hurricanes, floods and droughts. These changes have had profound impacts on human societies and ecosystems around the world, exacerbating existing social and environmental challenges and increasing the risk of future crises.
Good atmospheric ozone is found in the stratosphere, approximately 10 to 50 kilometers above the Earth's surface. It forms a protective layer that shields us from harmful ultraviolet (UV) rays from the sun. Bad atmospheric ozone, on the other hand, is found in the troposphere, the lowest layer of the atmosphere where we live. It is created by chemical reactions between pollutants and sunlight, mainly from emissions from industrial processes, vehicle exhaust, and some natural sources. This bad ozone is a primary component of smog and contributes to air pollution, respiratory issues, and other environmental problems.
Good atmospheric ozone refers to the ozone layer found predominantly in the stratosphere, which plays a vital role in shielding the Earth from harmful ultraviolet (UV) radiation emitted by the Sun. This ozone layer is distributed unevenly, with the highest concentrations occurring between 10 to 50 kilometers above the Earth's surface. On the other hand, bad atmospheric ozone refers to ground-level ozone, formed through a chemical reaction involving nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight. It is typically found in the lower atmosphere, closer to the Earth's surface, and is a major component of air pollution.
