Things To Know About Climate Change

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil, and gas. Climate change has many reported detrimental effects on our planet, so the call for action to change human behavior is critical.

The Causes of Climate Change

Since the Industrial Revolution, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which has adversely impacted Earth’s climate. However, natural processes, such as volcanic eruptions, also affect the Earth’s climate.

Causes, both human and natural, that combine to the acceleration of climate change are:

Greenhouse Gas Emissions

Concentrations of greenhouse gases have increased since the Industrial Revolution due to human activities. Carbon dioxide, methane, and nitrous oxide concentrations are more abundant now in the earth’s atmosphere than any time in the last 800,000 years.1 These emissions have increased the greenhouse effect and caused the earth’s surface temperature to rise. It’s been scientifically proven that burning fossil fuels changes the climate more than any other human activity.2

Greenhouse gases to be aware of are:

  • Carbon Dioxide: Human activities currently release over 30 billion tons of carbon dioxide into the atmosphere every year.3 Atmospheric carbon dioxide concentrations have increased by more than 40% since pre-industrial times, from approximately 280 parts per million (ppm) in the 18th century to 414 ppm in 2020.4
  • Methane: Human activities increased methane concentrations during most of the 20th century to more than 2.5 times the pre-industrial level, from approximately 722 parts per billion (ppb) in the 18th century to 1,867 ppb in 2019.5
  • Nitrous Oxide: Nitrous oxide concentrations have risen approximately 20% since the start of the Industrial Revolution, with a relatively rapid increase toward the end of the 20th century. The concentrations have increased from a pre-industrial level of 270 ppb to 332 ppb in 2019.6

Reflectivity or Absorption of the Sun’s Energy

Activities such as agriculture, road construction, and deforestation can change the reflectivity of the earth’s surface, which leads to local warming or cooling. This effect is observed in heat islands, which are urban centers that are warmer than the less populated areas. Buildings, pavement, and roofs tend to reflect less sunlight than natural surfaces, causing these areas to be warmer.

Emissions of small particles, known as aerosols, into the air can also lead to reflection or absorption of the sun’s energy. Many types of air pollutants undergo chemical reactions in the atmosphere to create aerosols. Overall, human-generated aerosols have a net cooling effect on the Earth.

Changes in the Earth’s Orbit and Rotation

Changes in the Earth’s orbit around the sun and the tilt and wobble of the Earth’s axis can lead to cooling or warming of the Earth’s climate because they affect the amount of energy the planet receives from the sun. These changes, known as Milankovitch cycles, cause climate changes on time scales of thousands of years. For example, the amount of summer sunshine in the Northern Hemisphere, resulting from changes in the planet’s orbit, appears to be the primary cause of past cycles of ice ages.  At the coldest part of the last glacial period (or ice age), the average global temperature was about 11°F colder than it is today. At the peak of the last interglacial period, however, the average global temperature was at most 2°F warmer than it is today.7

Volcanic Eruptions

Volcanoes have played a noticeable role in climate, with recent eruptions releasing large quantities of carbon dioxide. Some explosive volcano eruptions can throw particles into the upper atmosphere, where they can reflect enough sunlight back to space to cool the surface of the planet for several years. These particles are an example of cooling aerosols.

Volcanic particles from a single eruption do not produce long-term climate change because they remain in the atmosphere for a much shorter time than greenhouse gases. In addition, human activities emit more than 100 times as much carbon dioxide as volcanoes each year.8

The Effects of Climate Change

The entirety of the planet is warming. Since 1906, the global average surface temperature has increased by more than 1.6 degrees Fahrenheit (0.9 degrees Celsius), and is even more sensitive in polar regions.9 The impacts of rising temperatures aren’t waiting for some far-flung future; the effects of global warming are appearing right now.

Many people think of global warming and climate change as synonyms, but scientists prefer to use “climate change” when describing the complex shifts now affecting our planet’s weather and climate systems. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts.

Scientists have documented these current impacts of climate change:

  • Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, which cover West Antarctica and Greenland, and Arctic sea ice. In Montana’s Glacier National Park, the number of glaciers has declined to fewer than 30 from more than 150 in 1910.10
  • The majority of this melting ice contributes to sea-level rise. Global sea levels are rising 0.13 inches (3.2 millimeters) per year, and scientists have found that the rise is occurring at a faster rate in recent years.11
  • Rising temperatures are affecting wildlife and their habitats. Vanishing ice has challenged species such as the Adélie penguin, which is a species that has survived in Antarctica for nearly 45,000 years. Their population has since collapsed by 90% or more.12
  • As temperatures change, many species such as butterflies, foxes, and alpine plants, are on the move and migrating further north or to more elevated, cooler areas.13
  • On average, precipitation has increased across the globe. However, some regions are experiencing more severe droughts. This increases the risk of wildfires, lost crops, and drinking water shortages.14
  • Some species, including mosquitoes, ticks, jellyfish, and crop pests, are thriving. Bark beetles, for example, currently have booming populations that feed on spruce and pine trees, devastating millions of forested acres in the U.S.15

If climate change and the planet’s warming continues, we are expected to witness the following signicant effects:

  • Sea levels are expected to rise between 10 and 32 inches (26 and 82 centimeters) or higher.16
  • Hurricanes, tornadoes, and other storms are likely to become stronger. Floods and droughts will also become more common. By 2100, for example, large parts of the U.S. face a higher risk of decades-long “megadroughts.”17
  • Since glaciers store about three-quarters of the world’s fresh water, less of this incredibly important commodity will be available due to glacial melting.18
  • Many diseases will spread, such as mosquito-borne malaria and the 2016 resurgence of the Zika virus.19
  • Ecosystems will continue to change: Some species will move farther north or become more successful; others, such as polar bears, may not be able to adapt and could become extinct.20

3 Degrees Makes a Difference

Earth’s sea levels are rising at faster and faster rates as waters warm and ice sheets melt. Researchers led by Steve Nerem, a professor of aerospace engineering at the University of Colorado Boulder, looked at data dating back to 1993 to track sea-levels and temperatures. Their findings, which were published in the Proceedings of the National Academy of Sciences journal in 2018, show that sea levels and temperatures aren’t just rising, they’re accelerating.21

The research group Climate Central has created a plug-in for Google Earth to illustrate how catastrophic an unlikely, “extreme” sea-level and temperature rise scenario would be if the flooding happened today, based on 2017 projections from the National Oceanic and Atmospheric Administration.

Some of their findings and illustrations are as follows:

Now: The  Potomac River runs through Washington, DC.

The Potomac Before

3℃ Hotter: Rising sea levels will cause the Potomac River to rise and overflow into DC.

The Potomac 3 Degrees Hotter

Now: New York City sits on one of the world’s largest natural harbors.

3℃ Hotter: New York City could suffer from floods around the city’s perimeter and low-lying areas, such as the West Village, due to extreme flooding from the Hudson River.

NYC 3 Degrees Hotter

Now: San Francisco is prominent in the technology world and is home to the Golden Gate Bridge.

San Francisco Before

3℃ Hotter: San Francisco is also a peninsula, which means it can easily flood.

San Francisco 3 Degrees Hotter

Now: Charleston, South Carolina already suffers from a flooding problem due to being flat and having a low elevation.

Charlston Before 

3℃ Hotter: If sea-levels and temperatures continue to rise, a boat will be needed to get to the city center of Charleston.

Charlston 3 Degrees Hotter

Now: Residents of New Orleans, Louisiana are no strangers to the issues that come along with sea-level rise.

New Orleans Before

3℃ Hotter: New Orleans could completely disappear underwater, and in the next century, 500,000 people will have to leave the area to stay abov.

New Orleans 3 Degrees Hotter

How You Can Take Action Against Climate Change

In 2015, 196 countries signed on to a single, sweeping plan that aims to keep global warming to well below 2° C (3.6° F)—or even 1.5° C, which is known as the Paris Agreement. It aims to build on decades of gradual work by the international community to combat climate change and adapt to its impacts. To eliminate the release of heat-trapping carbon by 2050, world leaders must work together, strengthening their commitments and cutting greenhouse emissions to ensure a safe planet for future generations. However, you can take action, too.

Here are few ways you can join the fight against climate change:

Eliminate Food Waste

Food waste in the US occurs mostly in stores and at home—either because it spoils on the store shelf or before you can eat it. According to a Natural Resource Defense Council (NRDC) study, Americans throw away up to 40% of the food they buy.22 You can combat food waste by shopping for what you need, eating leftovers, composting scraps, and donating excess to food banks. Project Drawdown estimates that curbing food waste could avoid 70.5 gigatons of CO2, which would have a bigger impact than restoring 435 million acres of tropical forest.23

Use Clean Energy

Renewable energy is fundamental to powering the world as we move away from fossil fuels. Modelled after World War II “war bonds,” Clean Energy Victory Bonds—a bill introduced to Congress by Sen. Udall (D-NM), Reps. Lofgren (D-CA), and Reps. Matsui (D-CA)—would offer Treasury bonds as low as $25 to finance the government’s clean energy programs. Using your democratic rights, try asking your representatives to support this bill to make Clean Energy Victory Bonds a reality. Additionally, you can purchase renewable energy from installers such as Blue Pacific Solar and RGS Energy, as well as plug into renewable utilities with companies like Clean Choice Energy, which don’t require you to install any new hardware in your home to get sun and wind power.

Rethink Transportation

Overhauling the world’s transportation systems, both commercial and personal, would save as much CO2 as one billion acres of regenerative agriculture. Commercial trucks alone account for 6% of the world’s emissions—more than the collective emissions of airplanes around the globe. While individuals can’t revolutionize the shipping, flight, and automobile industries overnight, we can demand they change by voting with our dollars for public transit, using electric or hybrid vehicles, and reducing our total trips taken.

Recycle

Acquiring virgin resources—from logging trees to mining minerals—exploits more resources than recycling existing materials. For example, recycled aluminum products use 95% less energy than creating new ones.24 About 50% of recycled materials come from households; if that number were to increase to 65%, at-home recycling could prevent 2.8 gigatons of carbon emissions.25 However, recycling wrong can slow the system and create more waste, so be sure to rinse out your recyclables and stay up to date on local regulations to make sure what you recycle isn’t causing contamination.

Carbon Footprints and a Circular Economy: How You Can Contribute

Humans have thrived on Earth for millennia; from the beginning, we have always been a part of nature. However, since the Industrial Revolution, we have increasingly polluted the precious planet we call home. During this time, machinery was introduced such as the power loom and cotton gin to increase quality and efficiency over human labor. Reliance on fossil fuels for energy overshadowed the use of renewable energy sources like wood, water, and wind. These changes have caused domino effects that are now becoming crippling to our planet and our health.

Awareness of our global environmental crisis has sparked the urgent call to move away from a linear economy toward a circular economy. In contrast to the linear economic model, where we take, make, use, and waste, the principle of a circular economic model is regenerative, not extractive. It is where we take, make, use, recycle, reuse, repair, return, and strive to minimize waste as much as possible.

Diagram comparing a linear economy to a recycling economy to a circular economy

To reduce our carbon footprints, we must reduce our reliance on fossil fuels, minimize our urge to buy brand new items, and reuse/repair/recycle with rigorous habit.

Why are Carbon Footprints Important?

On average, each American citizen has a carbon footprint of 16 tons, which is the highest in the world.1  In other countries, the per capita average is around 4 tons.2  According to various studies, the ideal carbon footprint is closer to 2 tons.

If our carbon footprints continue to skyrocket due to fossil fuel extraction, pollution and waste, climate impact will become even more dangerous in the form of global temperature risings, severe weather, higher ocean temperatures, a decline in Arctic sea life, and decreased snow cover. These occurrences are all linked; warming oceans fuel horrific hurricanes. Higher, drier temperatures lead to melting ice caps and increases in wildfires. Our consumptive behavior has a long-term effect on our entire planet.

If you’re interested in calculating your own carbon footprint, you can do so here. It’s a free evaluation that will indicate the areas of your life that you can alter to achieve a smaller carbon footprint.

A Circular Economy Will Greatly Impact the World’s Carbon Footprint

According to the Ellen MacArthur Foundation, a circular economy is a way for us to imitate the cycles of nature: make something, use it, and reintroduce it to nature as a nutrient, or reuse it for something else. The loop entails the elimination of waste, regeneration of natural systems, and keeping products and materials in use. Today, we have the technology to change manufacturing processes to support a circular economy, but systemic change is never easy. To make the global impact necessary for the health and longevity of our planet, major changes will be needed from most of the world’s businesses, governments, and consumers.

We will all need to do our part to preserve Earth’s resources and dramatically minimize pollution. There are small changes that you can make to help propel the transition to a circular economy while shrinking your own carbon footprint. Here are a few ideas:

Your Transportation Methods Have an Effect on Your Carbon Footprint

Electric cars are a wonderful step towards minimizing your carbon footprint, considering they use almost zero fossil fuels. Hybrid cars are also a good option. They don’t eliminate the use of fossil fuels, but they do reduce them greatly.

It is also important to be aware of the way you drive. According to a study administered by Columbia University, you should avoid unnecessary acceleration and braking which can result in 40% more fuel consumption.3  Not only does that mean spending more money at the gas pump, but it’s dreadful for your carbon footprint, too. Listening to calm music may help you drive more serenely.

Air travel is also a contributor to greenhouse gas emissions. Taking a long-haul flight generates more carbon emissions than the average person in dozens of countries around the world produces in a whole year. The pandemic has curbed air travel significantly, which has had a positive impact on pollution, however travel is forecasted to increase as COVID19 herd immunity increases. If your air travel starts back up, you can offset emissions from your flights by donating to sustainable projects. For your next big trip, you can do this by visiting Native.

Ways to Reduce Your Home’s Carbon Footprint

If you spend a lot of time in your home, optimizing your household energy is an important step towards shrinking your carbon footprint. Getting a home energy audit is helpful for calculating the energy you use. To reduce your energy consumption, you can:

  • Turn down your water heater
  • Use LED lightbulbs
  • Turn off lights in rooms that aren’t being used
  • Switch to energy-efficient appliances
  • Take shorter showers
  • Turn off the tap while brushing your teeth

Renting or purchasing solar panels as an alternative source of energy can have dramatic benefits. Proper insulation can help avoid unnecessary energy expenditure to heat and cool your home.

The Groceries You Buy Have an Impact on Your Carbon Footprint

Going vegan is not for everyone though it is better for the environment to cut red meat out of even a few meals throughout the month. Cow farming transmits a substantial amount of emissions into the atmosphere, and it’s even been proven that these emissions are more dangerous than CO2 from cars.4  Next time you’re eyeing the red meat section, try grabbing ground turkey or tofu instead.

Avoid allowing rotten food to collect in your fridge. Strive to always use the ingredients that you pick up from the grocery store, as food waste is very damaging to the atmosphere and your carbon footprint. Americans discard around 40 million tons of various foods every year.5  Endeavor to purchase only the food that you’ll consume during the week to overbuying perishables that will go uneaten.

Strive to eat all your leftovers. Take the extra piece of chicken breast you made last night for lunch and use it the next day in chicken tacos. Or mix your random veggies for a salad so they don’t spoil. Small changes can make a big impact in the long run.

Humanist Beauty is Carbon-Neutral

Humanist Beauty supports the move toward a more circular economy. The brand maintains a carbon-neutral footprint. To do this, forecasted annual greenhouse gas emissions were calculated, including office operations, manufacturing, and all shipping. Through Carbon Fund, Humanist Beauty has ordered credits to support reforestry initiatives that completely offset emissions. Additionally, Humanist Beauty products are formulated with 100% naturally derived ingredients and packaged in recyclable componentry.
