Defining Climate Change

Climate change means big changes in global or regional temperatures and weather. Key signs include:

Consistent temperature increases³
Rising sea levels⁴
Increased extreme weather events⁴

Weather vs. Climate: Understanding the Difference

Weather talks about short-term weather conditions, while climate is about long-term trends. The greenhouse effect plays a key role in these changes, with carbon dioxide being the main greenhouse gas disrupting the natural balance⁴.

Scientists have seen huge warming trends since the 1950s, all linked to human actions³. The current warming rate is over 0.2 degrees Celsius per decade. This shows we need urgent action to protect our environment³.

The Science Behind Climate Change

Climate change is a complex issue that involves many environmental factors. To grasp this global problem, we need to understand how it affects our planet’s balance.

Greenhouse gases are key in controlling Earth’s temperature. The amount of carbon dioxide in the air has jumped from 316 parts per million in 1959 to over 411 parts per million in 2019⁵. This big increase shows how human actions are changing our climate.

Greenhouse Gases and Their Mechanism

Let’s look at what makes greenhouse gases special:

Carbon dioxide levels have increased by over 40% since preindustrial times⁵
Methane concentration has surged by more than 150%⁵
Nitrous oxide levels have grown approximately 20%⁵

The Greenhouse Effect Explained

The greenhouse effect is a natural process where certain gases keep heat in Earth’s atmosphere. Human activities have made this process stronger, causing more global warming⁶. The Earth’s surface temperature has gone up about 2 degrees Fahrenheit since the late 19th century, with most of this happening in the last 40 years⁶.

Human Contributions to Climate Change

Practicing sustainability is key to fighting climate change. Humans release around 10 billion tonnes of carbon every year, mainly from burning fossil fuels⁵. Deforestation, farming, and land use changes add up to about 25% of all greenhouse gas emissions⁷.

“We do not inherit the Earth from our ancestors; we borrow it from our children.” – Native American Proverb
