What is climate change? Climate change is a long-term change in certain weather patterns in an area. Climate change itself is often associated with global warming. Global warming is an increase in Earth's temperature which then lasts for a decade or more where one of the causes is climate change.

Check out a more complete discussion on Global Climate Change, starting with the following definitions, causal factors, impacts and mitigation efforts, check these out!

Greenhouse gasses are the first cause of climate change and come from greenhouse gases. Several gasses in the Earth's atmosphere itself play a role in this, for example in the glass in homes that trap the sun's heat and then stop it from leaking back into space.

After we know what is climate change, then we should know that many of these gasses occur naturally, although various human activities around them increase their concentrations in the atmosphere, in particular on methane, carbon dioxide (CO2), the fluorinated gas CO2 and nitrous oxide as the most common greenhouse gases produced by human activities and are responsible for over 64% of man-made global warming.

Concentrations in the atmosphere today are 40% higher than when industrialization began. The other greenhouse gasses themselves are emitted in smaller amounts, but they trap heat much more effectively than CO2, in some cases thousands of times more potent. This methane is responsible for 6% of nitrous oxide and 17% of man-made global warming.

The second cause of what is climate change comes from increased emissions caused by human activities, for example in the burning of oil, coal, and gas which will produce nitrous oxide and carbon dioxide. Ha is also caused by deforestation or logging.

Trees themselves help regulate the climate by absorbing CO2 from the atmosphere. Therefore when logging occurs, the beneficial effects are then lost and the carbon stored in the trees will be released into the atmosphere, and add to the greenhouse effect on earth. In addition, the increase in emissions is also caused by the increasing number of livestock, especially in cattle and sheep, both of which produce large amounts of methane when digesting food.

Fertilizers containing nitrogen also produce nitrous oxide emissions. These gases are fluorinated so that they produce a very strong heating effect, which is up to 23,000 times greater than CO2.

Weather patterns are an important part of life that will affect plants, and the food, water we consume, places to live, as well as various activities and human health. Therefore climate change will really have a serious impact on a person's life.

No one knows for sure what will happen in the future But experts then use science to provide an idea of ​​how the climate will then change for the worse if humans continue to clear forests, waste energy and use agricultural systems.

The possibility of ecosystem extinction, namely in animal and plant species, is 20-30 percent. This will occur if there is an increase in CO2 in the atmosphere and an increase in global average temperature of 1.5-2.5 degrees Celsius, which will then increase the level of ocean acidity. This will then have a negative impact on marine organisms such as coral reefs, to the various species whose lives depend on these organisms.

It is estimated that agricultural productivity in the tropics will decrease if there is an increase in the global average temperature of between 1-2 degrees Celsius, thus increasing the risk of famine.

The increasing frequency of floods and droughts will then have a negative impact on local production, especially on food supply in tropical and subtropical areas. If climate change occurs, then crop yields will also decrease, both in terms of quantity and quality.

Although emission levels continue to increase, there are also many opportunities to reduce them. One of them is through changes in consumption patterns and lifestyles. The following are some policy recommendations and instruments that can be done to reduce emissions on earth, such as:

In the energy sector, what can be done is to reduce subsidies on fossil fuels, tax the carbon used for fossil fuels, and promote the habit of using renewable energy, not forgetting to set electricity prices for renewable energy as well as subsidies for producers.

In the transportation sector, it is to promote the use of biofuels, require the use of fuel with CO2 standards for transportation equipment on roads, vehicle registration, unstuck Plebeian endbrain taxes, road use rates and parking.

Do not forget to also design a transportation need by prioritizing land use regulations and good infrastructure planning, finally trying to prefer to use non-motorized transportation and use public transportation facilities.

Applying standards and labels to various equipment, building regulations and certifications, including government pilots on procurement, incentives given to companies in the energy sector.

Moreover, around 70% of energy use comes from construction and buildings which account for 39% of carbon dioxide emissions, besides that in the next 15 years urban infrastructure will be built, along with the faster migration process from villages to cities (or vice versa).

Apart from that, it is equally important to improve the quality of the buildings erected, increase building standards, and rethink urban planning such as providing incentives for mini-grid solutions. Not only is it equally important to tackle human-induced CF11, methane and nitrous oxide emissions and then find smarter solutions for heating, cooling and waste management. All of that makes us know what climate change is and its effects for humanity.
