Since the pre-industrial period, we have been burning fossil fuels, which agitated greenhouse gas levels in Earth’s atmosphere, causes global warming. Climate change refers to both human and natural warming, but it is often used interchangeably with the term. It is the average increase in Earth’s surface temperature.
What causes global warming?
Greenhouse gases like carbon dioxide, methane, nitrous oxide, and ozone cause the greenhouse effect when they trap heat inside our atmosphere. When these gases enter the air from human activities such as burning fossil fuels, land clearing, deforestation, agriculture, waste disposal, and manufacturing processes, they absorb infrared radiation emitted by Earth’s surface and re-radiate some of their energy back into space.
How Does Carbon Dioxide Affect Our Planet?
Carbon dioxide is a naturally occurring gas that makes up about 0.04% of the atmosphere, and it’s essential to life on Earth because plants use carbon dioxide as their primary source of energy during photosynthesis. The amount of CO2 in our air has increased over time due to human activity such as burning fossil fuels like coal or oil. This increase in atmospheric CO2 levels can have an impact on climate change by causing global warming.
How do I know this isn’t just natural cycles?
Scientists agree that humans affect the climate because of CO₂ emissions from cars, power plants, and factories. Some people argue against artificial climate change because of its connection to pollution and deforestation. But studies show that even before modern industry, forests were already shrinking because of human population growth. And today, more than 90% of all Amazon rainforest destruction (Source: Vox – Youtube) takes place outside Brazil. So although nature plays a role in determining where we get our water and air, it doesn’t decide whether or not we use those resources wisely. We need to take responsibility for using them responsibly.
Is There Proof That Humans Are Causing Global Warming?
Human activities have increased Earth’s average surface temperatures by about 1°C since the pre-industrial period, which is currently rising by 0.2°C per decade. The majority of the current warming course is likely to result from human affairs since the ’50s. Over the course of decades to millennia, it is proceeding at an unprecedented rate.
A planet that has never been hotter. Climate scientists have concluded that to avoid the worst effects of global warming; we need to limit it to 1.5°C by 2040.
Is Global Warming Impacting People?
The impacts of rising seas and changing weather patterns affect people directly through flooding, storm surges, droughts, heatwaves, and other natural disasters. They also indirectly impact human health and well-being through changes in air quality, increased rates of infectious diseases, malnutrition, and mental illness. In addition, warmer oceans mean less oxygen dissolved into seawater, making it harder for fish to breathe. Rising waters threaten coastal communities around the world.
What can I do about it?
The good news is you don’t need to be an expert scientist to take meaningful steps toward addressing global warming. You just need to know where your food comes from, how much water goes into making products, what kind of transportation fuels you use, whether you recycle, and if so, which materials should go in recycling bins.
You can also make a difference by choosing environmentally friendly cleaning supplies, buying energy-efficient appliances, driving less or taking public transit instead of using cars, and turning off lights when not needed. And there are many other ways to reduce the impact that we have on our environment. The key is to start small and build up momentum over time.
