5 things you should know about the greenhouse gases warming the planet

Our livestock (cows, pigs, and chickens, for example) also pollute the atmosphere with methane from their digestion process. Gumdrop model of a carbon dioxide molecule, CO2 .It has one carbon atom and two oxygen atoms all bonded together. By making choices that have less harmful effects on the environment, everyone can be a part of the solution and influence change.

In the thirty years since, those projections of what would happen in a warming world have proven to be remarkably prescient. The new report was not the first to detail how the state was falling short of its climate goals. The report said that based on the most recent data available from the state, emissions have fallen just 11.5% below those of 1990. California has long been a leader in emissions control, and the new report has faced pushback from state officials who say they are much further along in hitting the goals than the report authors believe.

Metrics for the greenhouse effect

If all of this ice melted, sea levels would rise by about 70 meters (230 feet). Greenhouse gases allow the sun’s light to shine onto Earth’s surface, and then the gases, such as ozone, trap the heat that reflects back from the surface inside Earth’s atmosphere. The gases act like the glass walls of a greenhouse—thus the name, greenhouse gas. Increase in the total amount of greenhouse gases in the air has turned most of the world’s water bodies acidic. CO2 has consequently accumulated in the atmosphere at an average rate of 1.4 parts per million (ppm) by volume per year between 1959 and 2006 and roughly 2.0 ppm per year between 2006 and 2018.

A Runaway Greenhouse Effect Would Turn Earth Into a “Hellscape” - Popular Mechanics

A Runaway Greenhouse Effect Would Turn Earth Into a “Hellscape”.

But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average. Without the heating caused by the greenhouse effect, Earth’s average surface temperature would be only about −18 °C (0 °F). On Venus the very high concentration of carbon dioxide in the atmosphere causes an extreme greenhouse effect resulting in surface temperatures as high as 450 °C (840 °F).

But the amount of greenhouse gases in the atmosphere has skyrocketed to detrimental levels in recent history. As they heat up, the oceans, land and atmosphere release heat in the form of IR thermal radiation, which passes out of the atmosphere and into space. It's this equilibrium of incoming and outgoing radiation that makes the Earth habitable, with an average temperature of about 59 degrees Fahrenheit (15 degrees Celsius), according to NASA. Without this atmospheric equilibrium, Earth would be as cold and lifeless as its moon, or as blazing hot as Venus. The moon, which has almost no atmosphere, is about minus 243 F (minus 153 C) on its dark side. Venus, on the other hand, has a very dense atmosphere that traps solar radiation; the average temperature on Venus is about 864 F (462 C).

However, absorbed sunlight increases the temperature of Earth’s surface, and the warmed surface re-radiates as long-wave radiation (also known as infrared radiation). However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming. To understand global warming, it's first necessary to become familiar with the greenhouse effect, though. At top of stratosphere, 30 miles high, ozone absorbs most of the harmful ultraviolet radiation from the Sun.

What are the major causes of the greenhouse effect?

The program will also help meet the President’s goal of achieving a carbon pollution-free power sector by 2035 and net-zero emissions economy by no later than 2050. Soon after, the CEC released the state’s first inventory of greenhouse gas emissions in 1990 and a set of climate policy recommendations in 1991. This phenomenon occurs when the planet absorbs more radiation than it can radiate back. Thus, the heat lost from the earth’s surface is less and the temperature of the planet keeps rising. Scientists believe that this phenomenon took place on the surface of Venus billions of years ago. In general, smog is generally formed by the accumulation of more greenhouse gases including nitrogen and sulfur oxides.

As the planet's surface heats up, it releases some of the infrared energy that it had absorbed, but that energy doesn't make it back out of Earth's gaseous atmosphere. Instead of shooting back out into space, the infrared energy closely hugs our planet and, therefore, raises Earth's overall temperature. This is similar to how a human-built glass greenhouse works, trapping heat from the sun to keep plants warm in the winter. The world technically has only one-fifth of its "carbon budget"—the total is 2.8 trillion metric tons—remaining in order to avoid warming the Earth more than 1.5 degrees Celsius. Halting the trends in motion will require more than just phasing out fossil fuels.

The major ones are carbon dioxide, water vapor, methane, and nitrous oxide. The atoms are held together loosely enough that they vibrate when they absorb heat. Eventually, the vibrating molecules release the radiation, which will likely be absorbed by another greenhouse gas molecule. Most of the gas in the atmosphere is nitrogen and oxygen, which cannot absorb heat and contribute to the greenhouse effect.

Another effect involves changes in precipitation, such as rain and snow. The Intergovernmental Panel on Climate Change states that the global sea level rose about 1.8 millimeters (0.07 inches) per year from 1961 to 1993, and about 3.1 millimeters (0.12 inches) per year since 1993. Sometimes the greenhouse effect is quantified as a temperature difference. This temperature difference is closely related to the quantities above.

NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery. In the solar system, apart from the Earth, at least two other planets and a moon also have a greenhouse effect. A given wavelength of radiation may also be said to have an effective emission altitude, which is a weighted average of the altitudes within the radiating layer.

TransportationThe burning of petroleum-based fuels, namely gasoline and diesel, to power the world’s transportation systems accounts for 14 percent of global greenhouse gas emissions, as noted in the IPCC's Fifth Assessment Report. In the United States, transportation is the largest contributor of greenhouse gases. The greenhouse effect has supported life on the earth for millions of years. Today, however, the greenhouse effect is growing stronger as human activities such as deforestation and fossil fuel use release more and more greenhouse gases into the atmosphere.

Gases which can absorb and emit longwave radiation are said to be infrared active[61] and act as greenhouse gases. Washington – Today, April 22, as the Biden-Harris Administration celebrates Earth Day, the U.S. Environmental Protection Agency announced 60 selectees that will receive $7 billion in grant awards through the Solar for All grant competition to deliver residential solar projects to over 900,000 households nationwide. The grant competition is funded by President Biden’s Investing in America agenda through the Inflation Reduction Act, which created EPA’s $27 billion Greenhouse Gas Reduction Fund. The major cause of this phenomenon is the accumulation of natural greenhouse gases including chlorofluorocarbons, carbon dioxide, methane, etc.

The increasingly thick atmosphere might have created a drag on Venus' rotation period, leading to its bizarrely slow spin, in which a year goes by with only two days passing. The dense cloud cover also led to hellish surface temperatures on present-day Venus, with an average of 700 F (370 C) — hot enough to melt lead. The last time Earth's atmosphere had similar carbon dioxide concentrations was during the Pliocene epoch, between 3 million and 5 million years ago, according to the Scripps Institution of Oceanography in San Diego.
