Global Warming

Photosynthesis is when trees and plants remove carbon dioxide from the atmosphere. The carbon is separated and becomes part of the tree, and the oxygen is released. So a growing tree will store carbon all the time it is growing. More than half the weight of a tree is carbon. So photosynthesis by trees plays an important part in the Earth's carbon cycle.

Deforestation, the removal of forests, has been happening all over the world. When trees rot, or are burnt, they release the carbon (as carbon dioxide), and, of course, are no longer able to take carbon dioxide from the atmosphere. The carbon cycle is then disrupted, and more carbon dioxide, a greenhouse gas, builds up in the air. This (together with the burning of fossil fuels (coal, oil and natural gas)) is causing global warming and climate change.

Recycling involves collecting and processing materials like paper, glass, and plastic to create new products instead of disposing of them as waste. It helps conserve natural resources, reduce pollution from manufacturing, and decrease energy consumption compared to producing new materials from raw resources. Recycling also contributes to reducing landfill space and greenhouse gas emissions.

Ocean currents and winds can affect temperature by transferring heat energy from one place to another. Warm ocean currents can bring higher temperatures to coastal areas, while cold ocean currents can cool the air above them. Similarly, winds can transport warm or cold air masses, influencing the temperature of a region.

Yes, pollution is a global hazard that affects the environment, human health, and ecosystems worldwide. It can result from various sources, such as industrial activities, transportation, agriculture, and waste disposal, and can manifest in various forms, including air, water, and soil pollution. International cooperation and concerted efforts are needed to address and mitigate the impacts of pollution on a global scale.

Being in the care system can impact children and young people in various ways, including experiencing instability, loss of connection with family, and increased vulnerability to mental health issues. They may struggle with feelings of abandonment, lack of belonging, and lower self-esteem. Support and stable relationships are crucial in helping these individuals navigate the challenges they face and thrive in their development.

It doesn't reduce the amount of carbon dioxide in the atmosphere. It reduces the amount of gasoline your car burns because there are more, "miles to the gallon," and therefore reduces the amount of carbon dioxide your car produces.

Greenpeace advocates for renewable energy sources, promotes sustainable practices, and raises awareness about climate change through campaigns, protests, and lobbying efforts. They also work to hold governments and corporations accountable for their impact on the environment and promote policies that will mitigate climate change.

You can, alternatively, you can place the water tanks on your roof for a somewhat naturally heated source of water.

Co2 thickens the atmostphere above us, and by doing this, it traps more of the heat that enters the earth. Because the layer becomes thick, the earth is not able to bounce off as much heat as it does naturally, which leads to the earth heating up, which we call global warming

Winds in ice caps are typically strong and cold, originating from high-pressure systems and blowing across the flat, icy surfaces. These winds can create blowing snow and lead to the formation of snowdrifts, contributing to the harsh conditions in polar regions.

Some countries with emissions trading schemes include the European Union, the United States, China, and South Korea. These schemes aim to limit greenhouse gas emissions by allowing companies to buy and sell emission allowances.

Greenhouse gases do not have a single freezing point, as they consist of various compounds like carbon dioxide, methane, and water vapor. The freezing points of these gases vary depending on the specific compound. For example, carbon dioxide freezes at -78.5 degrees Celsius, methane at -182.5 degrees Celsius, and water vapor at 0 degrees Celsius.

The energy sources that can help stop global warming are renewable energy sources like solar, water (hydro, wave and tidal), wind, geothermal as well as biofuels of various kinds. All these help stop global warming because they produce electricity without releasing carbon dioxide greenhouse gas emissions. We have to stop relying on the polluting burning of fossil fuels for our future.

No, global warming results from humans increasing the amounts of carbon dioxide in the atmosphere. There is a certain amount of water vapor in the atmosphere that remains fairly constant and is part of the natural water cycle. In other words, human actions can not increase the water vapor in the atmosphere.

Global food shortage can lead to malnutrition, hunger, and increased susceptibility to diseases, particularly in vulnerable populations such as children and the elderly. It can also contribute to social unrest, political instability, and economic hardships in affected regions. Additionally, food shortages can drive up food prices, exacerbate food insecurity, and put pressure on natural resources and ecosystems.

One disadvantage of solar energy is that it is intermittent, as it relies on sunlight which is not available at night or on cloudy days. Another disadvantage is the high upfront cost of installing solar panels, despite decreasing costs over time, which can be a barrier for some individuals or businesses.

Mercury can contaminate soil and water, leading to harmful effects on ecosystems and wildlife. It can accumulate in organisms through bioaccumulation and biomagnification, posing a risk to human health when consumed through contaminated fish or water. Mercury pollution can also have long-lasting effects on aquatic ecosystems, disrupting food chains and overall biodiversity.

The atmosphere is primarily heated by the sun. Solar radiation warms the Earth's surface, which in turn heats the air above it. Other factors that can influence atmospheric warming include greenhouse gases and human activities that release heat-trapping emissions into the atmosphere.

Humans are causing global warming primarily by burning fossil fuels, such as coal, oil, and gas, which release greenhouse gases into the atmosphere. Deforestation and industrial processes also contribute by releasing additional greenhouse gases and reducing the Earth's ability to absorb carbon dioxide. These activities trap heat in the atmosphere, leading to a rise in global temperatures and disrupting the Earth's climate system.

Ozone holes form predominantly above the poles due to specific conditions in the stratosphere during polar winter. These conditions lead to the release of chemicals, like chlorofluorocarbons (CFCs), that break down ozone. The polar environment allows for the accumulation of these ozone-depleting substances, resulting in the formation of ozone holes.

CFCs are swirled around the world by the global winds. This can take up to ten years for them to reach the lower stratosphere but when there they are still effective at destroying ozone. CFCs in fact have a lifespan in the atmosphere of between 50 and 75 years.

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are greenhouse gases that are harmful to the ozone layer. When released into the atmosphere, they break down ozone molecules and contribute to the depletion of the ozone layer, leading to increased exposure to harmful UV radiation.

During prehistoric times in Toronto, the climate changed due to natural processes such as shifts in Earth's orbit and volcanic activity. This led to variations in temperature, precipitation, and ice cover, resulting in fluctuations between ice ages and warmer interglacial periods. These changes impacted the landscape, vegetation, and wildlife in the region over thousands of years.

A December 23, 2009 article at science.nasa.gov says that the Local Interstellar Cloud has a temperature of 6,000 degrees Celsius. This is approximately the same temperature as the surface of the Sun. Is this influencing temperatures on Earth? I don't know.
