What is climate change, what are its dangers and how will it affect the future on Earth ?
Sun-based cycle variations.
But since the XIX century, human activities have been the engine
The main causes of climate change, mainly due to the burning of fossil fuels
Such as coal, oil and gas.
The burning of fossil fuels generates greenhouse gas emissions that
It acts like a blanket enveloping the Earth, trapping the sun's heat and lifting
Temperatures.
Some examples of greenhouse gas emissions that cause
Climate change is carbon dioxide and methane.
These come from using gasoline to drive a car or coal to heat a building ،
For example: clearing land and forests can also lead to
To release carbon dioxide.
Landfills are also a major source of methane and energy emissions
Industry, transport, buildings, agriculture and land use are among
The main sources of emissions.
Greenhouse gas concentrations at their highest level in 2 million years
Emissions continue to rise and as a result, the temperature of
The Earth is now 1.1 C degrees Celsius higher than it was at the end of the century
Nineteenth.
The last decade (2011-2020) was the warmest on record.
Many people think that climate change basically means degrees
Heat warmer.
But overheating is only the beginning of the story.
Since the Earth is a system, to which the task is connected, the changes in
One area can affect the changes of all the others.
The consequences of climate change now include, among other things, drought
Severe , lack of water, severe fires , high water levels
The sea, floods , melting of the poles , catastrophic storms ،
Reduced biodiversity.
People are affected by climate change in a variety of ways
Climate change could affect our health and our ability to grow food
Housing, security and work.
Some of us are already more vulnerable to climatic influences, such as people who
They live in small island states and other developing countries.
Conditions such as sea level rise and water seepage have progressed
So salty that entire communities had to relocate ،
Prolonged drought will create a risk of famine.
The number of "climate refugees" is expected to increase in the future.
Every increase in global warming is important
According to the latest UN reports, thousands of scientists agreed
And government auditors have to limit the temperature rise in
All over the world to no more than 1.5 degrees Celsius will help us to
Avoid the worst climatic effects and maintain a subdued climate.
However, according to current national climate plans, it is expected that
Global warming reaches about 3.2 degrees Celsius by the end of the century.
The emissions that cause climate change come from all over the world and affect
For everyone, but some countries are born much more than others.
The 100 countries that emit the least generate 3 % of the total
Emissions.
The 10 countries with the highest emissions contribute 68%. The world should
Take action when it comes to climate, but peoples and countries
Those who create the most problems take responsibility for the work first.
We are facing a big challenge , but we already know several solutions
Many solutions to climate change can bring economic benefits while improving our lives and protecting the environment.
We also have global frameworks and agreements to guide progress, such as the development goals
Sustainable development and the United Nations Framework Convention on climate change
And the Paris Agreement.
There are three broad categories of actions: emission reduction ،
Adaptation to climate impacts and financing of necessary adjustments.
The transformation of energy systems from fossil fuels to renewable energies
Like the sun or the wind, it will reduce emissions that cause a change
The climate. But we have to start now.
Although a growing coalition of countries is committed to achieving emissions
Zero by 2050, but about half of the reductions in
Emissions must occur in 2030 to keep warming less
From 1.5 C.Fossil fuel production should decrease by about 6 ٪
Annually between 2020 and 2030.
Climate adaptation protects people, families, businesses and livelihoods
Infrastructure and natural ecosystems.
It covers possible current and future impacts. And there will be
Adaptation is needed everywhere , but now priority must be given
For the most vulnerable people and the least resources to deal with climate risks.
The rate of return can be high.
For example, disaster early warning systems save lives
As a material asset, it can bring benefits up to 10 times the initial cost.
We can pay the bill now, or pay it dearly in the future
Climate action requires significant financial investments by governments and companies.
But climate inaction is much more expensive.
One of the key steps is for industrialized countries to meet
Commitment to contribute 100 billion annually to developing countries
So you can adapt and move towards more environmentally friendly economies.
