The Consequences of Global Warming

1. Introduction

Global warming has become one of the most pressing issues of our time. In recent years, there has been an increase in public awareness and concern about the potential effects of global warming on our planet.

There is a lot of scientific evidence to suggest that global warming is real and is happening right now. The Earth’s average surface temperature has risen by about 0.8 degrees Celsius since 1880, and it is predicted to rise by a further 1.5 degrees Celsius by the end of the century. If this happens, it will have serious consequences for the environment and for human health.

2. What is global warming?

Global warming is the name given to the increase in the Earth’s average surface temperature over time. It is caused by the build-up of greenhouse gases in the atmosphere, which trap heat from the sun and prevent it from escaping into space.

The main greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide and ozone. They occur naturally in the atmosphere, but they are also emitted by human activities such as burning fossil fuels (coal, oil and natural gas), deforestation and agriculture.

3. How does global warming work?

The sun is the main source of energy for the Earth’s climate. The sun’s rays hit the Earth’s surface and some of this energy is reflected back into space while some is absorbed by the Earth. Greenhouse gases in the atmosphere trap some of this heat and prevent it from escaping into space. This makes the Earth’s atmosphere act like a blanket, keeping the planet warm.

4. History of global warming

The idea that greenhouse gases could cause global warming was first proposed by French mathematician Joseph Fourier in 1824. In 1896, Swedish chemist Svante Arrhenius calculated that industrial emissions of carbon dioxide could eventually triple the Earth’s natural greenhouse effect and lead to an increase in average global temperature.

The issue of global warming gained traction in the 1970s as scientists became increasingly concerned about the build-up of greenhouse gases in the atmosphere. In 1988, United Nations Environment Programme (UNEP) established the Intergovernmental Panel on Climate Change (IPCC) to provide a scientific assessment of the risk of human-induced climate change.
In 2001, IPCC released its third assessment report, which found that there was ‘new and stronger evidence’ that human activities were causing global warming. This report helped to raise further awareness about the issue and led to the negotiation of the Kyoto Protocol in 1997 – an international agreement to reduce greenhouse gas emissions. However, many countries failed to meet their targets under the agreement and it was not renewed after 2012.
In 2015, world leaders gathered in Paris to negotiate a new climate change agreement – known as the Paris Agreement – which aims to keep global temperature rise below 2 degrees Celsius above pre-industrial levels. As of 2019, 195 countries have signed and Ratified this agreement. Under its terms, countries must produce plans to reduce their greenhouse gas emissions and report on their progress every five years. The agreement came into force in November 2016.

5. The Paris Agreement

The Paris Agreement is an international agreement to combat climate change. It was negotiated at the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Paris in 2015 and came into force in 2016.

The agreement’s main goal is to keep global temperature rise below 2 degrees Celsius above pre-industrial levels. This is to be achieved by reducing greenhouse gas emissions and adapting to the impacts of climate change.

All countries that have signed the agreement are required to produce plans to reduce their greenhouse gas emissions and report on their progress every five years. However, there are no penalties for countries that fail to meet their targets.

The Paris Agreement has been widely praised as a major step forward in the fight against climate change. However, some critics argue that it does not go far enough to address the scale of the problem.

6. How does global warming affect the environment?

Global warming has a number of consequences for the environment.

Rising temperatures are melting polar ice caps and glaciers, which is causing sea levels to rise. This poses a threat to low-lying coastal areas, which could be flooded by rising waters.

Warmer temperatures are also making it harder for animals and plants to survive in their natural habitats. For example, warmer water temperatures are stressing coral reefs and making them more susceptible to bleaching. This can lead to the death of corals and the loss of habitat for marine life.

Climate change is also resulting in more extreme weather conditions, such as heatwaves, droughts and floods. These events can damage crops, homes and infrastructure, and disrupt supplies of food, water and power. They can also lead to displacement of people and loss of life.

7. How does global warming affect human health?

Global warming has a number of consequences for human health.

Rising temperatures can lead to heat stress, which can cause dehydration, exhaustion and even death. Heatwaves are becoming more common and more intense as a result of climate change, and they are expected to cause an increase in heat-related deaths in coming years.

Changes in weather patterns can also cause or exacerbate respiratory problems such as asthma. Air pollution, which is exacerbated by global warming, is linked to a range of health problems including lung cancer, heart disease and stroke.
Moreover, extreme weather conditions can lead to injuries, mental health problems and even death.
Climate change is also expected to cause an increase in the spread of vector-borne diseases such as malaria and dengue fever, as warmer temperatures provide ideal conditions for disease-carrying mosquitoes to thrive.
In addition, rising sea levels are putting coastal communities at risk of flooding and water contamination. All of these factors are likely to have a negative impact on human health and well-being in coming years. 8. How does global warming affect the economy? Global warming can have both positive and negative impacts on the economy.

In the short term, global warming can boost economic activity as people spend more money on cooling themselves in hot weather. In the longer term, however, the impacts of climate change are expected to be negative. For example, rising sea levels and more extreme weather conditions are likely to damage homes, infrastructure and crops, which will cost billions of dollars to repair. This will lead to higher prices for goods and services and could cause economic recession. In addition, climate change is expected to cause an increase in the spread of diseases, which will have a negative impact on productivity. All of these factors are likely to have a negative impact on the global economy in coming years.

9. What can be done to mitigate global warming?

There are a number of things that can be done to mitigate global warming.

Firstly, we need to reduce our emissions of greenhouse gases. This can be done by using less energy, switching to renewable energy sources and planting trees.

Secondly, we need to adapt to the impacts of climate change. This means preparing for extreme weather events and making our homes and infrastructure more resilient to them.

Thirdly, we need to engage in public awareness and education about climate change. This will help people understand the issue and make them more likely to take action to reduce their emissions.

10. Conclusion

Global warming is a real and pressing problem. It is caused by the build-up of greenhouse gases in the atmosphere, which trap heat from the sun and prevent it from escaping into space. This makes the Earth’s atmosphere act like a blanket, keeping the planet warm.
