What should we do about global change?

What can ordinary people do to combat climate change?

The answer given by experts is: respect nature and start with what you do.

Here are 16 little things that can stop global warming, and they're happening all around us.

1.Replace incandescent with fluorescent lamps.

Fluorescent lamps can achieve the same brightness with 40% of the energy of ordinary incandescent lamps, and 300 pounds of carbon dioxide can be avoided from being emitted into the atmosphere every year using fluorescent lamps.

2.When using air conditioning, it is two degrees Celsius lower in winter and two degrees Celsius higher in summer.

Almost half of the energy consumed in people's lives is used to heat and cool down. Lowering the indoor temperature by two degrees Celsius in the winter and two degrees Celsius in the summer can reduce carbon dioxide production by 2,000 pounds a year.

3.Clean the stove and air conditioner regularly, or replace the filter.

Doing so reduces emissions of 350 pounds of carbon dioxide into the atmosphere each year.

4.Do not leave the appliance on standby.

Use the switch button on the appliance to turn off the appliance directly, not with the remote control. For example, if the appliance is in standby mode for the remaining 21 hours, 40% of the electricity will be wasted.

5.Keep the refrigerator away from heat.

It's a good idea to switch to a refrigerator that automatically defrosts, as it's twice as energy efficient as the one you have now.

7.Do not leave the windows open for a long time, as heat will be lost.

In winter, the heater consumes a lot of energy in order to maintain the temperature in the room, which produces up to one ton of carbon dioxide.

8.Shop wisely.

It takes less energy to produce a one-liter beverage than a three-liter drink, so it is advisable to buy a large bottle of the drink.

9.Reuse shopping bags.

Shopping is to refuse to use the single-use plastic bags provided by the store, and carry a cloth bag by yourself, which not only saves energy, but also avoids the production of garbage.

10.Plant a tree.

A tree absorbs 1 ton of carbon dioxide as it grows.

11.Use green resources.

Wherever possible, use pure and renewable resources such as wind and solar energy.

12.Buy locally produced food.

This reduces the amount of dirt that is emitted by the car when transporting goods.

13.Buy fresh, not frozen, food.

Frozen foods consume 10 times more energy than non-frozen foods.

14.Eat less beef.

Aside from carbon dioxide, methane is undoubtedly the heaviest greenhouse gas. Cattle emit the most methane of any livestock, having four stomachs and regurgitating to release large amounts of methane.

15.Save gas.

Choose the right gear and don't slam on the brakes. If it takes more than 1 minute for the car to stop, turn off the engine.

16.Conservation of forest resources.

Protect the environment, live a low-carbon life, drive less cars, and ride more bicycles.

1.Protecting the environment Extraction of large amounts of resources, such as the burning of oil, coal, etc., will increase the release of carbon dioxide2Afforestation Plants can absorb carbon dioxide, and through photosynthesis, release oxygen, reducing carbon dioxide is equivalent to protecting the planet3

Low-carbon travel There are more and more private cars, and a lot of carbon dioxide in the air is the first part of the car exhaust, so we can use mine is to try to travel as green as possible, low-carbon travel 4Appeal to everyone Everyone on the earth has played a variety of roles, the earth is our home, and we protect the earth not only ourselves.

What can ordinary people do to cope with climate change? The answer given by experts is: respect nature and start with what you do.

Nature will respect us only if the laws of nature are fully respected. What we ordinary people can do is the little things around us: for example, try to reduce the emission of domestic exhaust gases; Cars drive less than one kilometer; If you can get a car with several people, don't drive one each, and if you can take the bus, don't drive a private car; The temperature of the air conditioner is slightly increased by one or two degrees; Use energy-saving spikes or lamps ......These "small activities" may be just a gesture or a small "unpleasantness", but they are to protect nature and our own living environment.

According to scientists, the rapid rise in paleo-Earth temperatures triggered a climate response that could have kept the climate warming going for thousands of years. A study published in Nature Geoscience** provides new evidence for climate feedbacks that could explain the long-term existence of Paleocene-Eocene thermal maxima (PETM), which is considered the best simulant of modern climate change.

The findings also suggest that today's climate change could have long-term effects on global temperatures, even if humans were able to control greenhouse gas emissions.

About 56 million years ago, PETM erosion intensified, releasing large amounts of fossil carbon stored in rocks and releasing enough carbon dioxide into the atmosphere, which has long affected temperatures, researchers said.

Scientists have found plenty of evidence of carbon release in coastal sediment fossils. They analysed the samples using an innovative molecular technique that allowed them to trace how processes such as erosion drive carbon over long periods of time. During PETM, the global temperature rises by about 9 to 9 degrees Fahrenheit, and conditions on Earth change radically.

Intense storms and flooding have become more common, and warm, humid weather has led to increased rock erosion.

Over thousands of years, carbon has been released from rocks and transported to the ocean via rivers as erosion progressively erodes mountains, some of which is redeposited in coastal sediments. Others are cautiously entering the atmosphere as greenhouse gases.

The researchers have developed a hybrid model to distinguish between the ** of carbon. Based on the amount of carbon in older samples, scientists were able to estimate how much carbon dioxide escaped during the transition from rocks to marine sediments. They estimate that climate feedbacks may have released enough carbon dioxide to explain the duration of PETM for about 200,000 years, which has not been well explained before.

These findings warn against the easing of modern climate change. If the temperature rises to a certain critical point, feedback is triggered, which leads to more violent temperature changes.

One lesson we can learn from this study is that when the climate gets wetter and hotter, carbon is not stored very well on land. Today, however, we are pushing the system to an imbalance, and even if we start to reduce CO2 emissions now, the situation will not get better right away.

1.Population ReductionThe rapid increase in population in recent years is one of the main factors contributing to global warming. At the same time, it also seriously jeopardizes the balance between the natural ecological environment.

With such a large number of people, the amount of carbon dioxide emitted by itself every year alone will be a staggering figure, and as a result, the amount of carbon dioxide in the atmosphere will continue to increase, and the resulting carbon dioxide "greenhouse effect" will directly affect the climate change on the earth's surface.

2.Reduce air pollution.

At present, the increasingly serious environmental pollution has become a major global problem, and it is also one of the main factors leading to global warming. Research on global climate change has now clearly indicated that the temperature of the Earth's surface has been rising since the end of the last century.

3.Planting more treesWorldwide, the forest area is declining dramatically due to natural or man-made factors.

4.Protecting animals is a precious resource for human beings, and biological diversity is the basis for human survival and development. But at present, the biological species on the planet are disappearing at an unprecedented rate.

5.Reducing water pollutionAccording to the Global Environmental Monitoring System water quality monitoring project, about 10% of the world's monitored river water is polluted, and since this century, human water consumption is increasing dramatically, and the scale of water pollution is also expanding, which forms a contradiction between the supply and demand of fresh fresh water. It can be seen that the treatment of water pollution will be very urgent and important.

6.Use less toxic waste.

The growing number of toxic chemicals not only poses a serious threat to human survival, but also harms the ecological environment on the earth's surface.
