Climate change in the world can be caused by various activities. When climate change occurs; temperatures can increase a dramatically. It can result in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. Oceans and glaciers have also experienced some changes: oceans are warming and becoming more acidic, glaciers are melting, and sea levels are rising. As these changes frequently occur in future decades, they will likely present challenges to our society and environment.
During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases build-up, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago.
Why does climate action matter ?
According to the various scientific studies, the natural resources would soon deplete completely. And result will be no power and total blackout and collapse of sophisticated lifestyle and activities of mankind. The Climate Emergency we currently face requires adequate and immediate action. It is one of the most pervasive and threatening crises of our time.
We are facing an existential threat and rapid prioritization of attention and action is necessary. If we continue along our current path, scientists say that the consequences will be devastating, having implications on where we live, how we grow food and other services vital to our well-being. A 2oC increase could mean more heat waves, a ten-fold increase in Arctic ice-free summers and a complete wipe-out of the world's coral reefs, home to millions of species.
Climate change impact on society
As a society, we have structured our day-to-day lives around historical and current climate conditions. We are accustomed to a normal range of conditions and may be sensitive to extremes that fall outside of this range.
Climate change could affect our society through impacts on a number of different social, cultural, and natural resources. For example, climate change could affect human health, infrastructure, and transportation systems, as well as energy, food, and water supplies. Some groups of people will likely face greater challenges than others. Climate change may especially impact people who live in areas that are vulnerable to coastal storms, drought, and sea level rise or people who live in poverty, older adults, and immigrant communities. Similarly, some types of professions and industries may face considerable challenges from climate change. Professions that are closely linked to weather and climate, such as outdoor tourism, commerce, and agriculture, will likely be especially affected.
Urban Populations Source: climatechange.org City residents and urban infrastructure have distinct sensitivities to climate change impacts. For example, heat waves may be amplified in cities because cities absorb more heat during the day than suburban and rural areas.
Cities are more densely populated than suburban or rural areas. Higher temperatures and more extreme events will likely affect the cost of energy air and water quality, and human comfort and health in cities.
City dwellers may also be particularly susceptible to vulnerabilities in aging infrastructure. This includes drainage and sewer systems, flood and storm protection assets, transportation systems, and power supply during periods of peak demand, which typically occur during summer heat waves.
Climate change will also likely affect tourism and recreational activities.
How to make life more Climate friendly
Being Climate conscious is not all about plastic bags; it's about making everyday choices that will quite literally determine our success or failure as a species. We can be more conscious about reducing pollution, protecting wildlife, conserving natural resources and take other actions that can help slow the rate of climate change. Everyone can make a difference, particularly when smart environmental choices become a habit and perhaps even begins influencing others into taking similar actions. Doing the right thing for the future of life on Earth can even have immediate personal benefits. It can tap into your creativity, can get you more engaged with your community and the world, and may contribute to a healthier lifestyle. We need to reduce the amount of trash we create, and to reuse or repurpose consumer goods rather than throwing them away.
1. Cut down on non-renewable energy sources
Installing solar panels and other forms of renewable energy systems in your home is a fantastic way of cutting your energy use, but it's not feasible for everyone. Other ways of reducing your carbon footprint is simply cutting down on the amount of energy you use on a day-to-day basis-including reducing the air-con and heating-by putting on a jumper or using a hot water bottle instead of turning up the heat on the thermostat, for example.

2. Change the way you travel
Ditching the car and switching to public methods of transport (bus, tram, subway) or choosing to cycle and walk places instead is another lifestyle change that benefits the environment. Alternatively, if public transport isn't an option, you might want to try carpools or vanpools-or working from home (i.e. telecommuting), which cuts down on transport emissions by cutting back on travel. On the subject of travel: cutting down on long-haul flights and taking Source: Getty images more time to explore your local area can drastically shrink your annual carbon footprint
3. Eat more plants, less meat
Livestock are a huge source of greenhouse gas emissions contributing 14.5 percent to the world's annual total, according to U.N. estimates. Sixty-five percent of that figure comes from cattle. By cutting out dairy and meat from your diet-or simply eating less-you can cut your carbon footprint drastically. A study by researchers at the University of Oxford in the UK found that excluding animal products from your diet can reduce the amount your yearly carbon emissions by 61 to 71 percent (the percentage is based on average per capita meat consumption in the U.S.). The Centers for Disease Control and Prevention (CDC) also recommends choosing food that is "local, healthy, environmentally responsible" to minimize energy usage involved in travels and chemicals that could harm local wildlife.
4. Remember-reduce, reuse, recycle
Another tip: remember the three R's. Reducing the amount of stuff we buy-whether that be clothes or tech-reduces the energy involved in the production of those products, which in turn reduces our carbon footprint. As well as ditching fast fashion and thinking twice before we upgrade, we can reduce energy use by reusing products purchased secondhand (vintage clothes, refurbished tech). Source : Getty images An iPhone X, for example, produces an average 79 kg of CO2 in its lifetime, according to a 2017 Apple report*. Eighty percent of that is released during production alone. But it's not just the energy involved. A simple cotton T-shirt can suck up 2,700 liters of water-just in the production of raw materials. That roughly works out at 17 bathtubs.
On the subject of being more mindful about the products we use: think about the environmental impact of the products you do buy. A new vehicle, for example, could be electric. A new heater, solar. A new lightbulb, more energy-efficient. And so on and so forth.
Some more lifestyle changes that we can follow
Cut down on processed foods
- It's becoming increasingly difficult to ignore how our eating habits are damaging the planet.Our food system affects groundwater supplies, generates a third of the world's greenhouse gas (GHG) emissions, and uses up a lot of land, which involves converting natural ecosystems and causes a loss of biodiversity.In response, scientists advise we cut down on meat, reduce food waste and buy more locally produced food.
Get energy-efficient appliances and electronics
- Energy-Efficient Appliances Help Prevent Greenhouse Emissions. So, the use of energy efficient appliances in your home such as dishwasher and refrigerator would help save energy that can also help reduce the greenhouse gas emissions and help protect the environment.
- Turn off lights when not in use
The power plants that supply electricity use fossil fuels, which are a major component of air pollution. By turning off lights when leaving a room, you can save a lot of energy and reduce electricity demand, which has a rippling effect.
- Take public transportation
Emissions from vehicles account for 40 per cent of the air pollution and using public transportation can help in reducing that. Here, we can reduce emissions by using public transport which can contribute in making the air cleaner.
- Walk or cycle
As the temperature gets warmer and the weather gets more unpredictable, fewer plant and animal species can survive. Switching to walking or cycling for more of our shorter journeys helps to protect biodiversity
- Print documents as little as possible
The volatile organic compounds (VOCs) and heavy metals in ink can lead to soil and even water pollution when left in landfill, while plastic can take thousands of years to degrade and even then, they will continue to pollute the soil.
- Recycle bottles, cans, newspapers, etc
Saves natural resources from being mined and harvested. Reduces the pollution created when extracting, processing, and shipping the raw materials
- Use reusable bags at the grocery store
Plastic bags use natural gas and crude oil to manufacture, they're non-biodegradable and they require even more fossil fuel to ship. When you use a reusable bag, you're decreasing the amount of non-renewable resources needed for producing plastic bags.
- Pay your bills electronically
It could restore ozone depletion. It could reduce pollution. It could save millions of trees annually.
- Unplug your devices to prevent phantom electricity from being consumed.
We often overlook the impact reducing our electric consumption can have on the environment around us. The truth is, unplugging unused electronics reduces our carbon emissions since most of our energy comes from fossil fuels.
- Wash your clothes in cold water
Roughly 75 percent of the energy required to do a load of laundry goes into heating the water. Using cold water saves energy, putting less pressure on electricity grids
Carbon Trading for Individuals?
Carbon trade is the buying and selling of credits that permit a company or other entity to emit a certain amount of carbon dioxide. The carbon credits and the carbon trade are authorized by governments with the goal of gradually reducing overall carbon emissions and mitigating its contribution to climate change. Individuals would be given a free allocation of carbon credits, on a per capita basis, which they would use to pay for purchases of electricity, petrol and gas. People that are low carbon consumers would be able to sell their surplus credits on the carbon market, whilst those with a high consumption would have to buy. The cost of carbon would therefore become included in everyday decision-making, which would promote energy efficiency and behavioural change, whilst encouraging the development of new low carbon technologies. The key features of such as scheme are that each individual is given the same 'right' to emit carbon. If they don't need all their freely allocated credits, they can sell the surplus on the open market, providing them with additional income. Those with a high demand for carbon would need to purchase additional credits to cover their consumption. The effect on business would be similar to that of a carbon tax, and this would be reflected in the price of carbon-intensive products. However, unlike a carbon tax,a cap and trade.
scheme like DTQs would be guaranteed to deliver the carbon reductions decided upon, as the carbon limit would be fixed for several years ahead. Such a scheme could be implemented on a national scale (the DTQ research centres on this proposal), or there may be scope for the existing EU Emissions Trading Scheme to be gradually expanded to encompass the whole economy. This would have the benefit of covering emissions from the whole of Europe, but may be more difficult to implement. While it is unlikely that personal carbon trading will be seen before 2010, it could certainly be implemented within the next 10 years using current technology.
Swedish fintech company Doconomy has launched a credit card that tracks the carbon dioxide emissions of purchases, and caps the climate impact of users' spending.
The DO Black credit card directly connects our consumption to the impact it has on the planet, in a bid to encourage us to actively reduce our carbon footprint each day.
Users can make their daily purchases with the DO card, tracking the carbon emissions associated with their spending via the DO app.
