Do you have any good suggestions on how to better deal with extreme weather and its possible disasters in the future?

We can review the snowstorm in Texas, which is the most widely known bad weather news recently. Who would have thought that in the south of North America, there would be such a serious snowstorm, and such an extremely cold crisis would plunge Texans into it.

In a state of anxiety.

Blizzard is freezing, however, it is actually the same thing as "global warming" that we have been talking about in recent decades. Of course, you can't mix cold and warm.

Say it, but "global warming" is not an accurate statement. The global temperature is indeed warming on the whole.

Yes, but for a certain period of time in a certain area, it is more manifested in extreme climate. In some areas, the abnormal increase of precipitation has brought floods.

Flood disaster; In some areas, the extremely cold weather in winter increases, which affects production and life; There are also rainy areas in the desert, primitive wind and rain.

This place is beginning to dry out; Some places are dry and rainy in summer, and mountain fires are frequent, while others are windy because of El Ni? o phenomenon.

All these have a far-reaching impact on people living there than the understated "global warming", but in the past,

After these extreme weather.

First of all, we should also realize that climate change is not limited to coastal areas threatened by "sea level rise"

Need to face, its threat can not be offset by "turning on the air conditioner in summer".

How does climate change happen? This is actually a difficult question to answer. Although the current climate has been proposed for several generations.

The change is probably mainly caused by human activities, but science always needs to tell evidence, solve problems and use scientific methods.

Law. The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) jointly established the Intergovernmental Climate.

IPCC, because governments around the world have realized that climate change has become an urgent task.

Face and solve problems, and then IPCC will study the causes, impacts and future solutions of climate change. ?

Second, every few years, IPCC organizes the world's top scholars to write assessment reports in three groups, among which 1 is the smallest.

The question to be solved by the group is how climate change is produced. What does it have to do with human activities? first

The sub-assessment report holds that the climate change in the past hundred years may be caused by human activities and natural fluctuations; second time

The assessment report further found that the climate change factors brought by human activities are becoming more and more obvious; The evaluation report almost asserts.

Climate change cannot be entirely caused by natural factors; According to the fourth assessment report, 90%

It can be considered that the increase of greenhouse gases brought by human activities has led to climate change; And this probability is in the latest round of evaluation

It has been further pushed up to 95%. Today, we can almost assert that global climate change is indeed caused by ourselves.

Yes Compared with the earth, man is just a tiny creature. How can such a tiny creature have an impact on the earth? , in very

It is not difficult to find such doubts in the arguments of conspiracy theories on climate change.

Third, when the climate change is so drastic, the previous "braking mechanism" is difficult to play a role. When the out-of-control chariot crosses a slope top, the situation will be.

Along the steep slope, it will get worse and worse. At the bottom of many seafloor, a large amount of combustible ice will be sealed in solid form and locked up.

Chains are high pressure and low temperature on the seabed. Climate change not only affects the atmosphere, but also the extreme weather that comes with it makes the ocean fever. if

After crossing the key node, the combustible ice on the seabed may disintegrate rapidly, and a large amount of greenhouse gas methane will rush into the atmosphere uncontrollably.

At the bottom of Babylon, we can find many traces of combustible ice that once broke.

Polar regions and plateaus have been frozen for tens of thousands of years.

A large amount of organic carbon is also stored in the soil, when road maintenance personnel in Siberia suffer from road diseases caused by melting permafrost.

When we are upset, we often ignore the more serious harm caused by 1.4- 1.6 trillion tons of organic carbon buried under the soil surface.

Of course, the earth has the ability to repair itself, but we don't. The earth may not need saving, but we must save ourselves.

According to the estimation of IPCC expert group, if the global average temperature reaches the node of 2℃, it is likely to give global monsoon, precipitation and ocean.

Sudden impacts such as flow, 2℃ has also become a turning point of climate change that we must adhere to. If possible, it is best to control it in the best state.

Control within 65438 0.5℃.

4. However, it is not easy to control global climate change within 2℃/ 1.5℃ and achieve the global goal of 2℃.

The world must achieve net zero carbon emissions before 2070, that is, the carbon emitted into the atmosphere is the same as the fixed carbon collected from the atmosphere.

Many, while the latter requires that this goal be achieved by 2050.

How to achieve net carbon emissions? The simple logic is to save resources, reduce our carbon emissions by opening up the flow, and find ways to fix the size.

Carbon in gas. The former requires us to improve the energy structure and greatly reduce the use of fossil fuels that release carbon.

Others ask us to promote the use of carbon capture technology with fixed carbon recovery as much as possible. ?

In order to achieve zero carbon emissions, many countries are trying to reduce carbon emissions, such as vigorously developing environmentally friendly energy (photovoltaic, tidal energy.

Sunseeker, wind energy) and new power generation methods (nuclear fusion, etc.). ), all in order to reduce the power generation industry's dependence on coal; Vigorously develop electric power

The popularity of automobiles and the large-scale construction of public transportation are all aimed at reducing carbon emissions in the transportation field.

5. Obviously, such emission reduction may reduce the scale of carbon emissions, but it is impossible to achieve zero emissions. At present, carbon capture technology is still developing.

At the demonstration stage, it is still immature, and there is still a gap from achieving zero net carbon emission.

Fortunately, we are not the only ones who do carbon fixation. Remember the first story I told? Its protagonist, those plants

Scientists are still fixing carbon in the atmosphere. We can plant trees ourselves, which is equivalent to offsetting our own emissions.

Partial carbon; Economically developed areas can also pay the fixed carbon (carbon sink) share of plants for areas with high forest coverage, which is equivalent to offsetting part of carbon emissions; More importantly, we can also use wood products sustainably to increase firmness.
