Why Is It Important to Study Climate Change?

Earth’s climate is undergoing changes never seen before by humans. Compared with levels before the Industrial Revolution, the global average temperature has risen a full degree Celsius. That may not sound like much, but it’s already severely impacted how our planet functions.

Greenland and Antarctica have lost enough sea ice to fill 400,000 Olympic-sized swimming pools. Extreme weather events are becoming more common. Heat waves that once happened every 50 years now happen almost five times as often, and that number is expected to rise further.

Studying climate change will help us understand why global temperatures continue to rise, how the climate affects us, and how we can tackle this challenge before things get much worse.

How will climate change affect us?

How will climate change affect us?

Left unchecked, climate change has the potential to:

  • Increase the frequency of natural disasters.
  • Damage natural ecosystems and human-built infrastructures.
  • Cause human health issues via food shortages, increased heat, pollution, and more.

Any change that affects the planet ultimately affects human beings. 

Take the oceans, for example. As seawater absorbs the heat of a warming planet, coral reefs start to die, leading to the deaths of multiple species. This will be catastrophic not only for the marine ecosystem, but for people as well. Coastal regions will find their food supplies greatly diminished. Companies that make pharmaceuticals will experience a shortage of key ingredients.

This is just one example; if climate change continues, we will see more and more snowball effects like these.

How does climate change affect human health and society?

The Intergovernmental Panel on Climate Change (IPCC) and the U.S. Global Change Research Program have described what will happen to human society in the face of further climate change:

  • Food shortages will occur due to temperature increases and changes in precipitation levels.
  • Droughts in drier areas will cause wildfires that reduce air quality, causing and worsening respiratory issues in humans.
  • Coastal flooding will become more common and severe as sea levels rise. Floods that once happened every 100 years could happen every year. 
  • Coastal cities and even entire island nations may disappear under rising waters.
  • Storms and rising waters will damage infrastructure, interrupting transportation and causing long-lasting power outages.
  • Temperature changes will increase people’s exposure to food-borne, water-borne, and insect-borne diseases
  • People will lose jobs as impacts on agriculture and other sectors increase

Communities with fewer resources will be hit hardest and fastest, but eventually, the impacts of climate change will reach everyone. 

How will climate change affect education?

How will climate change affect education?

According to the U.N., “Education is a critical agent in addressing the issue of climate change.” Climate change creates a need for up-to-date scientific knowledge. School curricula will be updated to include education about:

  • Sustainability—such as clean, renewable energy and best practices like reduce, reuse, recycle.
  • Environmental science concepts such as the greenhouse effect.
  • Climate change communication and policy.
  • Adapting to global climate changes.

Education will not only be about science and problem-solving, but also about confronting the public fear and doom and gloom of climate change. Education inspires and empowers; it’s about motivating people to learn and tackle the challenges of tomorrow, not just about finding problems.

How will climate change affect schools?

How will climate change affect schools?

Changing climate will affect learning at all levels:

  • Extreme weather events can close schools, turn school buildings into shelters, and even close schools entirely. 
  • In agricultural communities, loss of income due to droughts or extreme weather can force families to withdraw their children from school to help earn income.
  • In higher education, weather events devastate campus infrastructure and many schools don’t have the support or resources to make their systems more resilient. 

Fortunately, student communities are calling for more sustainability efforts, such as the use of renewable energy on campus. Student and community interest in climate change have also led institutions to offer formal climate change education, research, and community outreach.

Why is it important to learn about climate change?

Human activities are “unequivocally” responsible for global climate change, according to a  recent IPCC report. The best way to help change is to stay educated and informed about climate change. After all, we caused it, so it’s up to us to stop it.

Human activity and climate change 

Since the 18th century, humans have depended increasingly on fossil fuels like coal and oil. As we burn those resources, we release high levels of carbon dioxide and other greenhouse gases into the atmosphere. 

Our fossil fuel consumption has increased exponentially since the start of the Industrial Revolution. In 2019, we released a collective 37 billion tons of carbon dioxide into the atmosphere. 

We’re adding CO2 much faster than nature can remove it, and deforestation is worsening the imbalance. Since the start of the Industrial Age, atmospheric levels of carbon dioxide have increased by 40%, causing Earth’s air and water temperatures to rise.

Meanwhile, unsustainable agriculture processes have increased emissions of methane, another greenhouse gas. Methane warms the atmosphere 80% faster than the same amount of carbon dioxide.

We can reduce emissions and slow climate change, but we have to act collectively and without delay.

The power of education

Learning is the first step toward stopping global warming. Research has shown that when students complete courses in climate science, their relationship to climate issues changes in lasting ways.

Even five years after taking these courses, students report feeling strong personal connections to climate change issues. Some end up choosing careers related to climate action. Others get involved in their communities and educate others or advocate for policy change.

Many students change their daily behaviors after studying climate change. According to research, the impact of just one course can reduce a student's individual emissions by more than 2 and a half tons per year.

Researchers believe that if enough people went through this process, the total reductions would rival larger-scale efforts.

Why is solving climate change important?

Why is solving climate change important?

In the Paris Agreement of 2015, world leaders agreed that global temperatures should not increase by more than 1.5 degrees Celsius. Climate scientists believe that if warming stays below this target, humanity and planet Earth can avoid some of the worst effects of climate change. 

Right now, without human action, the planet is set to exceed the 1.5-degree global warming threshold in just 20 years, possibly hitting 3 degrees of warming within the century. 

Even at 2 degrees warming, the effects could be devastating. According to NASA:

  • Close to 100% of coral reefs would die.
  • 61 million more people would be exposed to severe drought.
  • Deadly heat waves could happen every year.
  • Up to 270 million more people would face water shortages.
  • Extreme weather events would become more common and more damaging.

A reduction in greenhouse gas emissions is the only way to re-stabilize the climate system and reduce the effects of climate change. Staying below the 1.5-degree global warming threshold will require sweeping widespread changes.

What can I learn about climate change?

Even someone without a scientific background can learn enough about climate change to be an informed advocate. Introductory level courses teach you about:

  • Causes of climate change
  • Climate models and the carbon cycle
  • How climate change impacts human health
  • Consequences to human and animal habitats
  • Possible future scenarios and the effect of human choices

You could learn the basics in an overview course, or dive more deeply into a particular aspect. Thanks to massive open online courses, there are many options available, including multiple free courses.
