The ABCs of Climate Change

We need to understand, to the best of our ability, the world around us in order to make meaningful changes.

With the guidance of scientist and educator Christa Sadler, we’ve created a resource for understanding the fundamentals of climate change. Our climate series will cover the role public lands play in climate change mitigation and adaptation. And the best place to start is to know the basics.

If you haven’t already, take the climate quiz to test your knowledge about climate change. After you’ve completed the quiz, we invite you to come back here to deepen your knowledge of climate change fundamentals.

Click on the following questions to reveal the explanations.

It’s about time.

Weather refers to the conditions of the atmosphere over a short period of time: days, weeks, or months. Weather is local or regional and has more to do with relatively short-term phenomena—like daily or seasonal changes.

Climate refers to the behavior of the atmosphere over a long period of time: decades, centuries, or millenia. Climate reflects a long-term average of weather events, and it depends largely on the amount of solar energy absorbed by Earth and retained by the earth’s atmosphere. Global warming contributes to changes in both weather and climate.1

To understand how this change happens, it’s important to know more about the greenhouse gases, solar energy, and the greenhouse effect.

Sunlight is radiant, providing heat energy to the Earth system.

The sun emits energy in different wavelengths, ranging from ultraviolet, through the visible spectrum of light, and on to infrared. Normally, the clouds and atmospheric gases absorb about 20% of this solar energy, 25% radiates back to space, and the rest is absorbed by the earth’s surface.

Solar Spectrum

The radiation produced by the sun is shortwave radiation (ultraviolet and visible light). Sunlight makes life possible. Plants use sunlight to make sugars and grow, which in turn sustains the rest of life on earth. Every bite you take is infused with the sun’s energy.

When solar radiation is absorbed by the earth, it reemits some of that energy as longwave radiation, also known as infrared radiation. Longwave/Infrared radiation produces what we experience as heat or warmth.

The amount of greenhouse gasses in the atmosphere impact how much of this energy dissipates into space and how much remains in the earth system.

Our earth is enveloped by an insulated jacket made from gases—and some of the gaseous materials that make up this jacket determine if we are too warm, too cold, or just right for plant and animal life.

Increasing greenhouse gas concentrations are expected to lead to climatic changes that may be difficult for species (including humans) to adapt to.

The Earth’s atmosphere is made up of gases held by earth’s gravitational pull. They are mostly nitrogen, oxygen, argon, and carbon dioxide. Most of these gases are within 10 miles above you now, then gradually dissipate over a few hundred miles into the vacuum of space. As solar energy enters the atmosphere and is absorbed and reemitted by Earth, these gases play an important role in regulating this energy/heat.

A key feature of greenhouse gases is that they absorb (and then reemit) infrared radiation/heat energy. As a result, when the earth absorbs incoming solar radiation and reemits some of that energy in the form of infrared radiation, not all of that dissipates back into space. The more greenhouse gases in the atmosphere, the more heat/energy is kept within Earth’s atmosphere.2

Greenhouse gases—which include water vapor, carbon dioxide (CO2), methane, ozone, and nitrous oxide—are those that have chemical structures that allow for efficient absorption of infrared radiation. In contrast, some gases in the atmosphere, such as pure oxygen (O₂) and pure nitrogen (N₂), are not considered greenhouse gases because their chemical structure is not conducive to absorbing and reemitting infrared radiation.

Greenhouse Effect

Water vapor is by far the most common greenhouse gas, but even in small numbers, CO2 and methane can have a big effect as they are more effective at absorbing longer wavelengths of light.

Special Note: One of the first scientists to discover the relationship between CO2 and a warming atmosphere was Eunice Foote. Her discovery in 1856 is largely overlooked, and we invite you to learn more about her innovative experiments here.

CO2 is a powerful absorber of heat energy and its concentration is greatly influenced by human activity.

Both CO2 and water vapor are impactful greenhouse gases. Although CO2 is not found in as high of concentrations as water vapor, CO2 concentrations are more significantly impacted by human activity (as are the concentrations of other greenhouse gasses such as methane).

Whereas the amount of water vapor in the atmosphere has remained relatively similar through time, CO2 concentrations have increased significantly over the past 200 years due to the Industrial Revolution and the building of economies centered on fossil fuels (increased warming from increased CO2 and methane can, however, impact the amount of water vapor in the atmosphere, potentially amplifying warming effects).

A great example of a runaway greenhouse effect is Venus, whose atmosphere is more than 96 percent CO2, and which has a mean surface temperature of 867 degrees Fahrenheit. If Venus ever had surface water, it long ago vaporized as the temperature rose.

For less extreme examples, there have been numerous instances throughout Earth’s past during which greenhouse gas concentrations have been significantly higher than they are today—however, it’s important to remember that these were times before contemporary species had evolved and most changes in greenhouse gas concentrations occurred over much longer time scales than they are today.

While our planet is habitable because of the presence of greenhouse gases, a proper balance is necessary to survive. If the concentration of those gases is too high, we end up with climatic conditions that humans (and many other plants and animals) are not adapted to.

Human activity has been a key driver of rapidly increasing greenhouse gas concentrations in the past 150 years.

In 1958, Dr. Charles Keeling began measuring atmospheric CO2 levels at the Mauna Loa Observatory. He compared ice cores from 1700 to 1958 with data from the observatory. His results showed that the level of CO2 in our atmosphere (expressed in parts per million–ppm) stayed relatively constant until the early 1900s, when it began to slowly and consistently rise.

Around the late 1950s, the curve of atmospheric CO2 concentration steepened dramatically.

The Mauna Loa (and other) research extends as far back as 10,000 years (through temperature proxies), demonstrating an essentially flat line that hovers around 280 ppm until suddenly skyrocketing in the late 1950s. Today, our planet’s atmospheric CO2 concentration is around 413 ppm—a level not seen for 3 million years–reflecting an exponential growth in greenhouse due to fossil-fuel-centric production and consumption.

And it’s still rising.3

Such abrupt changes in greenhouse gas concentrations may result in climatic changes at a pace that is hard to adapt to.

Earth’s climate has varied greatly throughout its entire history, including both “hothouse” and “icehouse” conditions. However, compared to investigations of past climatic change, what we observe today is the unprecedented speed at which we are changing atmospheric concentrations of greenhouse gases.

The rapidity with which this change is occurring may result in change to which biological systems (including our own) cannot adapt in time.4

Fossil fuel production, transportation, agriculture, and manufacturing are significant contributors of anthropogenic greenhouse gas emissions.

Although fossil fuel production (oil, gas, and coal) and transportation using those fossil fuels are often held up as a major culprit (and rightly so), humans also create greenhouse gases in many other ways.

Agriculture (both plant and animal production) is responsible for up to a quarter of all greenhouse gas emissions. Deforestation and burning for development and agriculture releases the carbon that was stored in plants (and also removes a major receptacle—or “sink”—that previously took up extra CO2 in the atmosphere).

The manufacture of concrete (which is the most common building material around the world) releases CO2, as does the manufacture of plastics.

Air conditioning, too, is a large source of greenhouse gases, and the use of air conditioning is increasing around the world as countries become more affluent (and as the need for it increases along with rising temperatures).

These are just a few examples of how human activity emits greenhouse gases.5

There are significant implications across all of earth’s systems.

It affects pretty much everything, as these systems are interconnected. The atmosphere affects our oceans and is in turn affected by them. This relationship means that a warming atmosphere results in warming oceans. As wind patterns change, they will change the ocean currents below. This ultimately affects the normal circulation of cold and warm water currents, which causes massive changes in global weather patterns at sea and on land, affecting things like the position, shape, and strength of the Jet Stream and the Gulf Stream, among many others.6

Think of a warming planet as the earth on steroids. The systems that naturally occur on our planet become bigger, stronger, faster, and more unpredictable. Thus, where we normally have a hurricane season, we now have bigger and more powerful hurricanes each season as the storm systems draw more energy from the warmer sea water.

As ice caps and glaciers melt, the additional cold, fresh water changes ocean circulation and makes storm cycles shift. Winters get colder in cold places. Summers get hotter. Arctic “bomb cyclones” hit the northeast U.S. as the Jet Stream moves. Droughts settle over the southwestern United States and Australia. Europe’s flood cycle and frequency is changing.7 Places that normally experience drought are experiencing much deeper and longer dry spells, causing massive wildfires, which release even more carbon into the atmosphere.8

Conversely, regions with a wetter climate are often being inundated with precipitation, causing more flooding, which only worsens near the coasts as sea level rises from melting ice.9

There are several major climate change variables that researchers monitor to watch for trends in global warming. Among others, these include sea level, land surface air temperature, sea surface temperature, summer Arctic sea ice extent, glacier mass, and snow cover in the northern hemisphere.

Indicators show an increase in a warming world, such as sea level, sea-surface temperature, and temperatures over ocean and land.

In the American Southwest, climate change is expressing itself in the form of warmer and drier weather, decreased snowpack in the high country (which results in less groundwater infiltration and decreased river flows), fewer but more violent monsoon storms, longer summers, and shorter, drier winters. Are there years that seem more like the “normal” ones we knew 40 years ago? Certainly, but the overall trend is clear.10

It goes without saying that there are many social, economic, and health implications of these changes, both in the Southwest and worldwide. Plant and animal species have become extinct, or have moved far from their original territories, and farming and ranching are now more of a gamble.111213

There are still many ways that we can both adapt to and mitigate the effects of climate change—in our personal lives, businesses, industries, food production, and transportation. Over the next few months, we’ll look at how climate change is affecting our world, both close to home and further afield, and we’ll also explore ways that we can be a part of the myriad possible solutions.

One of the best places to start this journey is on our public lands, especially at Grand Staircase Escalante National Monument. So stay tuned for October’s discussion about the importance of public land in the climate change picture.

If you would like to learn more about the basics of climate change and how our climate system works, the following are some excellent places to find information. There are many websites and resources for people of all ages, so we hope you’ll go learn more about this issue and how it is affecting our planet.

To Conclude

We know from climate science that we can not stop climate change, but we can mitigate impacts and plan for how we will adapt—as a species and a world—to climate change.

For Partners, this means including climate change in all mission-driven programming land management advocacy related to Grand Staircase. It means considering climate change as we complete our strategic goals, plan our conservation activities, and design educational materials.

What can we do differently to mitigate climate change and plan for necessary adaptation? Is there something we can do in the Escalante watershed to ensure our ecosystems survive drought? Is there something we can do through education to help people better understand how protecting nature is one of the best ways for us to ensure that we are able to live in a climate changing world? These are the kinds of questions we will continue to ask. It is essential that we plan as much as possible—and saving Grand Staircase and public lands is an essential component of our planning.

Ultimately, we are planning for our survival, and the survival of our planet.

We hope you will join us.
