What is Global Warming?

Global warming refers to the long-term rise in global average temperatures on Earth. It is caused by increased concentrations of greenhouse gases in the atmosphere, such as carbon dioxide and methane. These gases trap heat and radiation from the sun in the Earth’s atmosphere, causing it to warm up over time.

The greenhouse effect is the process that causes global warming. Certain gases in the atmosphere, known as greenhouse gases, absorb some of the sun’s radiation and trap this heat rather than allowing it to escape back into space. This raises temperatures on the Earth’s surface and in the lower atmosphere.

Without the natural greenhouse effect, the average temperature on Earth would be very cold, around -18°C. However, human activities like burning fossil fuels have increased the concentrations of greenhouse gases and amplified the greenhouse effect, causing the Earth to warm at an accelerated rate.

Causes of Global Warming

The primary cause of global warming is the burning of fossil fuels like coal, oil, and gas, which emits greenhouse gases into the atmosphere. As the Natural Resources Defense Council explains, “Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.”

According to the Intergovernmental Panel on Climate Change, emissions from fossil fuels account for over 75% of global greenhouse gas emissions and were found to be the dominant cause of global warming. In 2018, fossil fuel emissions accounted for 89% of total global CO2 emissions.

When we burn fossil fuels like coal, oil, and natural gas for energy, carbon dioxide is released into the atmosphere. This added carbon dioxide, along with other greenhouse gases like methane, contributes to the greenhouse effect and causes the planet to warm through the trapping of heat. The continued burning of fossil fuels at current rates is projected to raise global temperatures and lead to severe climate change effects.

Effects of Global Warming

Global warming is already having significant and harmful effects on the planet. Here are some of the major consequences:

Rising temperatures

As greenhouse gases trap more heat, global surface temperatures are increasing. The past five years have been the warmest on record. Higher temperatures are causing more extreme heat waves, increased risk of wildfires, expanded ranges of infectious diseases, and heat-related illnesses.

Extreme weather events

The increased heat is also causing more frequent and severe storms, floods, and droughts in many parts of the world. Extreme weather disasters now cost the global economy over $100 billion per year.

Melting ice caps

Warming oceans and air are melting polar ice sheets and mountain glaciers at unprecedented rates. Over the past 40 years, Arctic sea ice volume has declined by over 75%. Melting land-based ice causes global sea levels to rise, threatening coastal communities.

How Individuals Contribute to Global Warming

Individuals contribute to global warming in several key ways through their daily activities and choices. Three major areas where individuals have an impact are: use of electricity, transportation, and food consumption.

The use of electricity generated from fossil fuels like coal and natural gas is a major contributor to global warming. When fossil fuels are burned to generate electricity, they release greenhouse gases like carbon dioxide and methane into the atmosphere. These greenhouse gases trap heat, causing the planet to warm. The average individual uses electricity to power their homes, appliances, devices, and more, so the collective electricity usage contributes enormously to greenhouse gas emissions.

Transportation is another key way individuals contribute to global warming. Most transportation relies on the burning of fossil fuel in vehicles. According to the EPA, transportation accounts for around 28% of total U.S. greenhouse gas emissions. Driving gasoline-powered cars and taking air travel are significant sources of greenhouse gas emissions from transportation that individuals have control over through their choices.

Finally, food consumption, especially of meat and dairy products, is a major contributor to global greenhouse gas emissions. The production of meat and dairy relies heavily on methane-producing livestock like cows and sheep, as well as land clearing that releases carbon dioxide. One study found that meat and dairy provide just 18% of calories but take up 83% of farmland and produce 60% of agriculture’s greenhouse gas emissions (1). By reducing consumption of meat and dairy, individuals can drastically lower their carbon footprint.

Benefits of Energy Efficiency

Using energy-efficient products has many benefits, including reducing electricity usage, saving money, and reducing carbon footprint. According to the Environmental Protection Agency (EPA), improving energy efficiency in homes, commercial buildings, manufacturing, and transportation could reduce CO2 emissions by over 50% by 2050 (source). Energy-efficient products like LED light bulbs, Energy Star appliances, and improved insulation help reduce energy consumption in buildings. The EPA estimates that Energy Star certified products helped Americans save over $30 billion in energy costs in 2014 alone.

In addition to environmental benefits, energy efficiency provides economic benefits. The Department of Energy reports that energy-efficient technologies could save U.S. consumers and businesses over $120 billion annually on energy bills by 2030. Investments in energy efficiency create new jobs, with over 2.25 million Americans employed in energy efficiency related fields today (source). Adopting energy-efficient practices allows individuals and businesses to spend less money on energy costs and more money on other priorities.

By using less electricity, energy-efficient products reduce dependence on fossil fuels like coal and natural gas. This decreases greenhouse gas emissions that contribute to climate change. The International Energy Agency estimates that energy efficiency improvements could deliver over 40% of the emissions reductions required to achieve international climate goals (source). Ramping up energy efficiency is one of the most cost-effective ways for individuals to reduce their carbon footprint and combat global warming.

Types of Energy Efficient Products

There are many types of energy efficient products that consumers can purchase to reduce their energy usage and carbon footprint. Some of the most impactful products include:

LED light bulbs – LED bulbs use up to 90% less energy than traditional incandescent bulbs and last 25 times longer. Replacing all lights in a home with LEDs can reduce lighting energy usage by 75% (cite source: https://www.energystar.gov/products/products_list)
Energy Star appliances – Appliances with the Energy Star label are certified to save energy without sacrificing features or functionality. Energy Star refrigerators, dishwashers, washing machines, and air conditioners can reduce energy use by 10-50% (cite source: https://www.energysage.com/energy-efficiency/energy-efficiency-products/)

Choosing energy efficient models for appliances, lighting, electronics, vehicles, and building upgrades is one of the most impactful steps individuals can take to reduce energy usage and carbon emissions.

Barriers to Adoption

Two major barriers prevent wider adoption of energy efficient products: higher upfront costs and lack of information.

Energy efficient appliances, lighting, and other products often cost more upfront than less efficient models. For example, an Energy Star certified refrigerator may cost $50-100 more than a standard model (1). Even though long-term energy savings usually offset the higher initial costs, many consumers focus only on the purchase price and opt for cheaper, less efficient models.

Limited information and understanding of energy efficiency also hinders adoption. According to a UPenn study, low-income households lack access to energy use data and have limited knowledge about potential cost savings from efficiency upgrades (2). Without visibility into their energy costs and potential savings, consumers fail to value energy efficient models properly.

Targeted incentives and education programs can help overcome these barriers. Governments and utilities use rebates, financing assistance, and community partnerships to reduce upfront costs. Informational campaigns that promote total cost of ownership and lifetime savings of efficient products also spur adoption.

Government Incentives

Federal, state, and local governments provide rebates and tax credits to help offset the upfront costs of energy efficient products and make them more affordable. The federal government offers tax credits covering 30% of the cost, up to $2,000, for energy efficient home improvements like adding insulation, energy efficient windows and doors, certain roofing materials, and heating and cooling equipment that meets Energy Star requirements.

Specific tax credits are also available for installing alternative energy equipment like solar panels, wind turbines, fuel cells, and geothermal heat pumps. Many utility companies and states give rebates on the purchase of energy efficient appliances and electronics as well. By reducing the upfront costs through incentives, governments aim to encourage more widespread adoption of products that save energy and reduce greenhouse gas emissions over the long term.
