Global warming is likely to be the greatest threat of the 21st century. Global warming is a phenomenon of climate change that is characterized by a general increase in the earth’s average temperature and leads to long-term changes in the balance between the climate and the ecosystem. This is directly related to the increase in greenhouse gases in our atmosphere, which increases global warming. Current climate change encompasses both global warming and its effects on the earth’s climate patterns. we have seen previous periods of climate change, but the current changes are rapid and not natural.
Facts about our changing climate:
- Global warming increasing due to some human activities. I am sure we all know the reasons, burning down fossil fuels for energy, doing agriculture and intensive farming for meat and plant production, and most importantly Chopping down forests and trees to make space for other uses.
- The temperature of the earth has risen by about 1 degree Celsius in the last century. With a slight temperature rise, we may not notice much of a difference in our daily life, but that temperature rise has had a significant impact on the planet.
- Half of the world’s coral reefs have died in the past 30 years. Human activity and high temperatures contribute significantly to coral bleaching. This affects fish and other species that make these corals their home. Between 2014 and 2017, the bleaching of the Northern Great Barrier Reef combined with cyclones’ effects and killed about 50% of its corals.
- With rising global temperatures, it will be harder for our societies to adapt to the changes it brings, and some species are more likely to become extinct.
The effects of climate change around the world are not being felt in the same way – people living in the poorest countries and geographically vulnerable regions (such as small island states) will suffer the first and hardest blow. This is because communities living in poverty are more likely to be exposed to environmental risks, are often more dependent on natural resource-based livelihoods, such as agriculture, and have fewer resources to deal with climate impacts.
What are world leaders doing to stop climate change?
In 2015, in Paris, leaders from 197 countries pledged to give people a priority and reduce their country’s greenhouse gas emissions. The Paris Agreement aims is to limit global warming to below 2 ° C and ideally to 1.5 ° C. If governments act swiftly on the promises, they made in the Paris climate agreement and implement the solutions now, there’s still hope of avoiding the worst consequences of climate change.
Climate change determines our time on earth and is happening faster than feared. But we are powerless against this global threat. As Secretary-General Antonio Guterres stated in September: “The climate emergency is a race we losing, but it is a race we can win.”
