The Climate Change Debate: What We Know for Sure and What We Must Do about It

Climate change is a pressing issue that has sparked much debate and discussion in recent years. While some people deny its existence or downplay its severity, the overwhelming majority of scientists and experts agree that it poses a significant threat to our planet and our way of life. In this article, we will explore what we know for sure about climate change and what actions we must take to address it.

What We Know for Sure

There is a wealth of evidence that supports the reality of climate change. The Intergovernmental Panel on Climate Change (IPCC), a group of scientists from around the world, have compiled and analyzed extensive data on the subject. Their findings show that the Earth’s climate is changing, and it is changing because of human activity. We know that:

1. The Earth’s temperature is rising: The average global temperature has increased by about 1 degree Celsius (1.8 degrees Fahrenheit) since the late 19th century. This may not seem like a lot, but small increases in temperature can have a significant impact on the environment.

2. The Arctic is melting: Arctic sea ice is melting at a rapid pace, with the summer minimum decreasing by almost 13% per decade.

3. Oceans are getting warmer: The oceans absorb much of the excess heat from the Earth’s surface, which has led to an increase in ocean temperatures. This, in turn, can disrupt marine ecosystems and cause more frequent and severe weather events.

4. Sea levels are rising: As temperatures rise, ice sheets and glaciers are melting, causing sea levels to rise. This can cause flooding, erosion, and other damage to coastal communities.

What We Must Do About It

It is clear that climate change is a serious problem that requires urgent action. Here are some of the actions we must take to mitigate its effects:

1. Transition to renewable energy: The vast majority of our energy comes from burning fossil fuels, which release carbon dioxide into the atmosphere. We must shift towards using renewable energy sources such as solar and wind power to reduce our dependence on fossil fuels.

2. Reduce emissions: Burning fossil fuels is not the only source of greenhouse gas emissions. We must also address emissions from transportation, industry, agriculture, and other sources.

3. Protect and restore ecosystems: Healthy ecosystems such as forests and wetlands can absorb and store carbon. We must protect and restore these ecosystems to help combat climate change.

4. Adaptation and resilience: Even if we take significant action to address climate change, its effects will still be felt. We must develop strategies to adapt and become more resilient to the changes that are coming.


Climate change is a complex issue, but the science is clear. We must take action to mitigate its effects and prevent further damage to our planet. By transitioning to renewable energy, reducing emissions, protecting ecosystems, and becoming more resilient, we can work towards a healthier and more sustainable future. It is up to all of us to take action and make a positive impact on the world.
