The Changing Climate

What is climate change?

Climate change refers to the long-term alteration in the earth's climate system, including changes in average temperature, precipitation, and other weather patterns that have occurred over the past century or more. One of the primary drivers of climate change is the burning of fossil fuels, such as coal, oil, and gas, which releases carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat and prevent it from escaping into space, leading to a warming of the planet's surface. In addition to fossil fuels, other human activities such as deforestation and agriculture also contribute to greenhouse gas emissions.

To address climate change, it is essential to reduce greenhouse gas emissions. This can be done in several ways, including transitioning to renewable energy sources such as solar and wind power, increasing energy efficiency, and reducing waste. Many countries have set targets to reduce greenhouse gas emissions, and international agreements such as the Paris Agreement aim to limit global temperature rise to below 2°C above pre-industrial levels.

Rising sea levels, more frequent and harsher heatwaves, droughts, and wildfires, as well as stronger and more frequent storms and changes in precipitation patterns are all consequences of climate change. Natural systems, including the habitats of plants and animals, water supplies, and agricultural output, are significantly impacted by these consequences. Along with having negative social and economic effects, they also cause property and infrastructure damage as well as the eviction of individuals from their homes and loss of livelihoods.

There is general agreement among scientists that human actions are the main reason why the Earth's climate is changing so quickly. At the local, national, and international levels, actions are being taken to reduce greenhouse gas emissions.

How can we make a difference?

The change for the future of the planet can start at home, while global and national efforts to address climate change are crucial, individual actions and choices also play an important role in reducing greenhouse gas emissions and mitigating the impacts of climate change.

Individual actions at home can contribute to reducing greenhouse gas emissions, including:

  • Reducing energy consumption: By using energy-efficient appliances, turning off lights and electronics when not in use, and reducing heating and cooling usage, individuals can reduce their carbon footprint and save money on energy bills.

  • Conserving water: By fixing leaks, using low-flow showerheads and toilets, and reducing water usage, individuals can reduce the amount of energy required to treat and transport water, which in turn reduces greenhouse gas emissions.

  • Reducing waste: By recycling, composting, and reducing the amount of waste sent to landfills, individuals can reduce methane emissions, which is a potent greenhouse gas.

  • Using sustainable transportation: By walking, biking, carpooling, or using public transportation, individuals can reduce their carbon footprint and promote sustainable transportation options.

  • Eating a plant-based diet: By reducing the consumption of meat and dairy products, individuals can reduce the carbon footprint of their diet, as livestock farming is a significant source of greenhouse gas emissions.

Individual choices on the use of transportation can also affect climate change. Transportation is one of the largest sources of greenhouse gas emissions in the United Kingdom, accounting for approximately 27% of total UK greenhouse gas emissions in 2019. To decrease climate change, it is essential to reduce transportation-related emissions by promoting sustainable transportation options. Here are some ways to use transportation to decrease climate change using UK figures:

  • Use public transportation: Public transportation, such as buses, trains, and the London Underground, are more fuel-efficient and emit fewer greenhouse gases per passenger than private cars. According to the UK Department for Transport, using public transportation instead of driving alone can reduce emissions by up to 90%.

  • Walk or bike: Walking or biking is a zero-emission transportation option that can also promote health and reduce traffic congestion. In the UK, the government has invested in cycling infrastructure, including cycle paths and bike-sharing schemes, to encourage more people to cycle.

  • Use electric or hybrid vehicles: Electric or hybrid vehicles emit fewer greenhouse gases than traditional gasoline-powered cars. According to the UK Department for Transport, the number of electric vehicles registered in the UK has increased significantly in recent years, with over 225,000 electric vehicles registered by the end of 2020.

  • Reduce unnecessary driving: Reducing the amount of driving, such as by combining trips or telecommuting, can also reduce transportation-related emissions. In the UK, the government has encouraged remote work during the COVID-19 pandemic, and some employers have continued to offer remote work options to reduce commuting emissions.

In addition to promoting sustainable transportation options, the UK government has also implemented policies and practices to reduce transportation-related emissions, such as investing in public transportation infrastructure, promoting electric vehicle adoption through tax incentives and grants, and implementing low-emission zones in some cities.

Individuals can advocate for policies and practices that address climate change at the community, national, and global levels in addition to reducing greenhouse gas emissions at home. This includes promoting sustainable transportation options, promoting renewable energy initiatives, and advocating for policies that promote a low-carbon economy.

In conclusion, climate action begins at home, and individuals can make a significant contribution to reducing greenhouse gas emissions and mitigating the effects of climate change through their daily actions and choices.
