Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. Today, emissions are higher than ever before in human history and global warming has become one of the greatest threats to our planet and its inhabitants. The effects of global warming are already being felt around the world, most noticeably through warming temperatures and rising sea levels. This means that we need to take action now if we want to prevent any further destruction and loss of life.
What Causes Global Warming?
Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas), which produces heat-trapping gases.
The Impacts of Global Warming
Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pests migration, changes in forest structure and functionality. pest invasions, intense storm damage and salt invasion, just to name a few.
How It Affects Different Regions Of The World
While the Earth’s climate is changing in response to greenhouse gas emissions, how it affects different regions of the world will vary significantly. Some places are getting hotter while others are getting colder. Some places get wetter and others drier. As a result, different regions of the world will be impacted differently as some areas become more habitable for plants and animals, but other areas might have to make way for new flora and fauna due to extreme changes in environment. Climate change affects all regions around the world. Polar ice shields are melting and the sea is rising. In some regions extreme weather events and rainfall are becoming more common while others are experiencing more extreme heat waves and droughts. These impacts are expected to intensify in the coming decades.
What We Can Do About It
Everyone can help limit climate change. From the way we travel, to the electricity we use and the food we eat, we can make a difference. Start with these 10 actions to help tackle the climate crisis.
Save energy at home
Much of our electricity and heat are powered by coal, oil, and gas. Use less energy by lowering your heating and cooling, switching to LED light bulbs and energy-efficient electric appliances, washing your laundry with cold water, or hanging things to dry instead of using a dryer.
Walk, cycle, or take public transport
The world’s roads are clogged with vehicles, most of them burning diesel or petrol. Walking or riding a bike instead of driving will reduce greenhouse gas emissions – and help your health and fitness. For longer distances, consider taking a train or bus. And carpool whenever possible.
Eat more vegetables
Eating more vegetables, fruits, whole grains, legumes, nuts and seeds, and less meat and dairy, can significantly lower your environmental impact. Producing plant-based foods generally results in fewer greenhouse gas emissions and requires less energy, land, and water.
