Creating a Future That Is Sustainable

 With record high temperatures, many wildfires, and devastating flooding in Asia this summer, as if the Northern Hemisphere's experiences weren't enough, there is now little question that the climate is changing—and quickly. Although there have always been variations in the Earth's climate over time, the current warming is occurring at a rate that has not been seen in the last 10,000 years.

What Causes the Climate to Change?

Eight cycles of ice ages and warmer times have occurred on Earth in the last 800,000 years. The end of the last ice age, around 11,700 years ago, signaled the start of the current climatic era and the development of human civilization. The majority of these temperature shifts are thought to be caused by minute changes in Earth's orbit, which alter how much solar radiation reaches our planet.

Since the industrial revolution in the middle of the 19th century,

when scientists first discovered that gases like carbon dioxide and others trap heat and keep more of the sun's energy in the Earth's atmosphere, the current warming trend is very different and is happening at a rate not seen in many recent millennia. In addition to causing widespread and quick changes in the atmosphere and oceans, this additional energy has warmed the land, the ocean, and the atmosphere.

Earth orbiting satellites and new technology have enabled scientists to gather a wide range of data on our planet and its climate globally, enabling them to glimpse the broad picture. As the accompanying chart illustrates, these data, which were gathered over a number of years, demonstrate the patterns and indicators of significant change.

The Proof

For example, a large number of NASA's scientific instruments currently analyze how these gases impact the passage of infrared radiation through the atmosphere in order to better understand our climate. There is no doubt that rising greenhouse gas levels cause Earth to warm based on the observed effects of these gas increases.

The Earth's climate is sensitive to variations in greenhouse gas concentrations, as evidenced by ice cores taken from tropical mountain glaciers, Greenland, and Antarctica. Tree rings, ocean sediments, coral reefs, and sedimentary rock strata are other sources of ancient information. According to this old data, the rate of warming that is happening right now is around ten times quicker than what is typically seen following an ice age. After the previous Ice Age, carbon dioxide from human activity increased roughly 250 times faster than from natural sources.

How can the climate change be addressed?

It is undeniably true that climate change is a huge and complicated issue, and that there are occasionally more theorists, academics, and activists than practitioners and doers. Furthermore, even though reducing or at least containing global warming is the main problem, all current targets seem to lead to 2050, which may be too late to keep temperature below 1.5C.

It's an easy question to answer. Who is in charge of it? Who generates carbon?

In actuality, it is each of us individually or as a part of the organizations that offer us services. Based on our consumption and lifestyle choices, the average CO2 footprint of individuals in the UK is 10 tonnes per year, a number that has not significantly altered over the past 30 years. We also know that homes and automobiles account for more than 40% of the CO2 emissions in the UK that are produced by individuals and communities. However, no one entity—national or local government, business or nonprofit, public sector, or pressure group—can resolve the problem on its own. Either everyone wins or nobody wins. In order to address what is acknowledged to be the largest and most pressing issue of our (or any previous) era, everyone must collaborate and work together.

Even while it's becoming more widely acknowledged that "something" needs to be done quickly,

there needs to be a significant rise in decisive action, especially in the area of meaningful and active citizen participation. How can local governments, who everyone interacts with and many of which have declared a climate emergency in their area, engage local communities and individuals to lower demand, lower emissions, and create a more sustainable future?

Community concerns are wide-ranging and diverse, but as we are all aware, the main problem facing the UK right now is the cost of living, which was brought on by rising energy prices and is pushing a large number of people into fuel poverty. A few more are the expense of switching from gas to heat pumps, the dearth of reasonably priced low-carbon public transportation (or any public transportation at all), and inadequate insulation in homes.

It seems like "somebody else's problem" all the time. In other words, to put it simply, people and communities need to understand that Net Zero is a problem for us. It involves more than simply corporations and/or local or national governments. These organizations play a significant macro role, but communities also need to lower demand, which calls for a multifaceted shift in behavior.

Why include citizens and communities?

Residents are the ones who directly encounter the issues, difficulties, and prospects for sustainability improvement. By giving people a hands-on approach to sustainability, we can leverage their expertise, abilities, and inventiveness while boosting their sense of ownership, dedication, and drive to bring about change and maintain the outcomes. In addition to fostering greater commitment, involving citizens in sustainability-related continuous improvement may enhance teamwork, communication, and problem-solving skills.
