What activities would contribute the most global warming?

Burning fossil fuels is the primary way humans contribute to global warming.

which one out of these:

driving a solar powered car
snowmobiling around national park
launching an engine less glider
trekking by horseback

Rainshine is right. Which is the only one that burns fossil fuels?

The third one?

No. An engineless glider?????

Think through this. Use the process of elimination. Is a solar powered car very conducive to global warming? No. It uses the sun's energy, not contributing to global warming. If something does not have an engine it obviously does not use fossil fuel therefore not exuding it into the environment. Horseback? No. Just no. A snowmobile, though does have an engine which does use fossil fuel and does contribute to global warming. Hope I helped.

To determine which activities contribute the most to global warming, we can look at the major greenhouse gases emitted by human activities. The most significant greenhouse gases contributing to global warming are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Here are a few activities that contribute significantly to global warming:

1. Burning fossil fuels: The burning of coal, oil, and natural gas for electricity generation, heating, transportation, and industrial processes is one of the largest sources of CO2 emissions. Power plants, vehicles, and industries that heavily rely on fossil fuels are major contributors to global warming.

2. Deforestation and land-use changes: When forests are cut down or burned, the stored carbon is released into the atmosphere as CO2. Deforestation not only leads to increased CO2 emissions but also removes the capacity of trees to absorb CO2 through photosynthesis. Additionally, land-use changes like the conversion of forests to agricultural land or urban areas also contribute to global warming.

3. Livestock and agriculture: Livestock farming, especially cattle, produces significant amounts of methane from enteric fermentation (digestive process) and manure management. Methane is a potent greenhouse gas. Additionally, the use of synthetic fertilizers in agriculture releases N2O, another powerful greenhouse gas.

4. Industrial processes: Certain industrial processes, such as cement production, steel manufacturing, and chemical production, lead to substantial CO2 emissions. The production of these materials often involves the combustion of fossil fuels and chemical reactions that release greenhouse gases.

5. Transportation: The burning of gasoline and diesel fuels in cars, trucks, airplanes, and ships releases considerable amounts of CO2 into the atmosphere. As transportation demands increase worldwide, the associated emissions contribute significantly to global warming.

It's important to note that these activities contribute to global warming in different ways and to varying degrees. The exact contribution of each activity can depend on factors such as regional differences, energy sources, and technological advancements. Nonetheless, addressing these key sources of greenhouse gas emissions is crucial in mitigating global warming.
