Climate change: a simple guide to understanding global warming | Technique

Global temperatures are rising due to human activity and climate change is now threatening all aspects of our lives.

Look: Farmers and scientists in Peru develop climate-resistant potatoes

If this increase is not controlled, humans and nature will suffer from overheating disastrous, with increasingly severe droughts, the dramatic rise in sea level and the massive extinction of species.

We are facing a huge challenge, but there are possible solutions.

Look: 10 cities in the world could be flooded due to the climate crisis

What is climate change?

Climate is the average weather of a place for many years. Climate change is a Change in those medium conditions.

The rapid change in the climate we are seeing now is caused by the people we use Oil, gas and coal their homes, factories, and transportation.

Look: Is it possible to reduce global warming and save humanity?

When this fossil fuel is burned, it releases greenhouse gases, mainly carbon dioxide (Carbon Dioxide). These gases trap the sun’s heat and cause the planet’s temperature to rise.

The world is almost now 1.2°C warmer than in the nineteenth century, the amount of carbon dioxide in the atmosphere increased by 50%.

Scientists say warming must slow if we are to avoid the worst consequences of climate change. They say global warming should stay indoors 1.5°C for 2100.

However, unless immediate action is taken, the planet could remain warm by more than 2 degrees Celsius by the end of this century.

And if nothing is done, scientists believe global warming could exceed 4°C, causing unprecedented heat waves, causing millions of people to lose their homes to rising sea levels, leading to severe droughts and irreversible loss. It has biodiversity.

What is the impact of climate change?

Extreme weather events such as heat waves, storms and droughts are already becoming more severe and threaten lives and livelihoods.

With further warming, some areas can become UninhabitableAgricultural land turns into desert.

In other regions, the opposite is happening, where heavy rains have caused historic floods, as seen recently in China, Germany, Belgium, and the Netherlands.

The people of the poorest countries will suffer the most, because they do not have the money to adapt to climate change. Many farms in developing countries already have to put up with very hot climates and it’s only going to get worse.

Our oceans and their habitats are also threatened. For example, Australia’s Great Barrier Reef has already lost half of its coral reefs since 1995 due to rising seas due to climate change.

Wildfires are becoming more frequent as climate change increases the risks of hot, dry weather conditions.

And as permafrost in places like Siberia thaws, greenhouse gases trapped for centuries will be released into the atmosphere, exacerbating climate change.

Finally, in a warmer world, animals will have a harder time finding the food and water they need. For example, polar bears can die because the ice they depend on is melting, and elephants will have a hard time finding the 150-300 liters of water per day they need to survive.

At least scientists have calculated that 550 species could be lost this century, The number will increase if no action is taken.

How will different parts of the world be affected?

Climate change has different impacts in different regions of the world.

Some places will get hotter than others, some will receive more rain, while others will experience more droughts.

In the link below you can see in detail how Latin America will be affected.

What do governments do?

Countries agree that climate change can only be addressed by working together and in a signed historic agreement Paris 2015 Pledge to make efforts to preserve global warming 1.5 degrees Celsius.

The United Kingdom is organizing a summit of world leaders, called COP26, in November, when countries will outline their 2030 carbon reduction plans.

Many countries have committed to reaching net zero by 2050, which means reducing greenhouse gas emissions as much as possible and balancing the rest by absorbing an equivalent amount from the atmosphere.

Experts agree it can be done, but it will require major changes from governments, businesses and individuals.

What can we do individually?

Big changes have to come from governments and companies, but scientists say some small changes in our lives can limit our impact on the climate:

• Fly less
• Do not use the car and do not use electricity
• Buying energy-saving products, such as washing machines, when we have to replace them
• Change the heating system from gas to electric
• Use insulating materials to keep the house warm or cool
