Q:

What are the positive effects of global warming?

A:

Quick Answer

Positive effects of global warming include fewer deaths in winter due to cold weather, lower costs of energy for heating homes and other buildings, and better agricultural production. Additionally, warmer temperatures facilitate sea transportation in the northern parts of the Earth.

Full Answer

In most parts of the world, deaths from cold in winter exceed deaths from heat in summer. Winter temperatures especially impact the poor, who cannot afford to sufficiently heat their homes. A rise of even a few degrees of temperature annually decreases fuel expenditures, saves lives and reduces medical costs. Additionally, many people prefer warmer climates, as evidenced by the tendency of retirees to move to southern locations. Global warming also increases levels of carbon dioxide in the atmosphere. Plants thrive in areas with high carbon dioxide concentrations, and crops that absorb more carbon dioxide may grow larger and have increased yields. Warmer climates also open up land for agricultural use in areas that were previously too cold for farming.

In the north, global warming enables commercial fishing at higher latitudes and opens up previously closed areas for shipping. For instance, the fabled Northwest Passage in northern Canada can become a reality, enabling ocean-going traffic to move from the Pacific Ocean to the Atlantic Ocean and back by a northern route.

    How does global warming happen?

    A:

    Global warming happens when carbon levels in the atmosphere rise, trees are cut down in large quantities and the ozone layer is destroyed. Without managing these things, the Earth risks suffering from adverse effects.

  • Q:

    How does global warming affect people?

    A:

    Global warming affects people by impacting climate with higher temperatures and catastrophic weather conditions, causing health problems by exacerbating pollution and spreading pests, and decreasing living space through rising sea levels. These conditions bring on famine, drought, epidemics and financial turmoil.

    How do you write a global warming thesis statement?

    A:

    According to the Online Writing Lab at Purdue University, your thesis statement should be a debatable one which any reasonable person could agree or disagree with. Concerning global warming, whether the stance is for or against, making a claim about its impact or the policy decisions made by government backed by evidence is a much stronger thesis then a generalized statement about whether global warming is good or bad.

    What gases play a role in global warming?

    A:

    The gases that play a role in global warming include carbon dioxide, nitrous oxide, methane, chlorofluorocarbons and water vapor. These compounds are called greenhouse gases because their presence in the atmosphere can be compared to the actions of the glass surrounding a greenhouse.
