Why has the US withdrawn from the Copenhagen climate agreement?

Give back to the big sponsors of the election and stand up for petrochemical interest groups.

Trump, speaking calmly in front of the people from the point of view of American interests and jobs, stressed the need for the United States to withdraw from the Paris climate. The main reason for the withdrawal was the re-election of the sponsors as a platform for petrochemical interest groups, and Trump's move was actually to give back to the big money owners who supported his election and fulfilled his promises. According to the United States, in Trump's campaign funding, oil, gas, coal, and other companies and executives have far outnumbered Obama's donations.

For every $10, $1 comes from petrochemical interests, such as resources and oil. During the same period, Obama received $34 from the petrochemical group for every $1. Lobby groups fight for victory, and in the United States, there is the so-called lobbying system, that is, the lobbying system.

Major interest groups lobby companies to help them have a say on policy by hiring former **senior** representatives, and to build an open system that favors their own policies.

Since Trump took office, companies in the petrochemical industry, such as oil and gas, have increased their capital spending on lobbying. In contrast to the Democratic Party, the Republican Party is inherently close to the big bloc and represents the essence of the big bloc's interests. This can be seen in the composition of the Democratic and Republican parties.

The Democratic Party is mostly made up of lawyers, prosecutors, etc., while the Republican Party is made up of big entrepreneurs. Initially, with the advent of Trump, many thought he would speak for the lower middle class in the United States, especially in the rusty areas. But it is clear that, judging by some of Trump's policies, he is still a firm corporate stance, deregulating finance, increasing military spending, opening up more petrochemical energy, cutting taxes for companies, etc.

The ultimate beneficiaries are actually big entrepreneurs.

Against the Democratic Party, the political ecology of the United States is basically a drama between two parties. The attitude of the Democratic Party and the Republican Party is opposite, and the Republican Party also agrees with the absolute position of the Democratic Party. After Trump took office, Obama's previous political legacy, including health care reform, loose relations with Iran, the TPP, and the Paris Climate Agreement, was almost completely rejected.

The TPP was abolished as soon as it was proposed, health care reform is underway, and relations with Iran are once again in a cold wave.

The main purpose of the climate agreement is to control greenhouse gas emissions and keep the concentration of greenhouse gases in the earth's atmosphere at a stable level. The main reason why the United States insists on withdrawing from the agreement is that if it is to abide by the agreement, it will certainly have a certain impact on economic development. The United States is for the economy, regardless of the global climate.

In fact, it boils down to one sentence: money. To the detriment of the United States, the Paris climate agreement bans the use of coal in the United States and allows China and India to do so, which Trump feels is unfair.

The U.S. withdrawal from the Copenhagen climate agreement is due to the content of the agreement, which may offend the economic development of the United States, as well as the development of the industry.

One.. The United States said on the 25th that Obama will propose at the Copenhagen summit that greenhouse gas emissions will be cut by 17% from 2005 levels by 2020. Obama will attend the United Nations Climate Change Conference in Copenhagen, Denmark, on December 9.

Two.. Singapore's Prime Minister said that Singapore will also contribute to global efforts to reduce emissions by taking further steps to reduce carbon emissions if other countries commit to meeting their obligations under the new global environmental agreement. Singapore is a small country, and its carbon emissions are less than the global total.

Three.. China** has announced specific targets for controlling greenhouse gas emissions. The goals were adopted at the *** executive meeting held on November 25.

The meeting decided that "by 2020, China's carbon dioxide emissions per unit of GDP will be reduced by 40% to 45% compared with 2005, and will be included in the medium and long-term planning of national economic and social development as binding indicators, and corresponding domestic statistics, monitoring and assessment methods will be formulated." The meeting also decided that by vigorously developing renewable energy and actively promoting the construction of nuclear power, China's non-fossil energy will account for about 15% of primary energy consumption by 2020; Through afforestation and enhanced forest management, forest area increased by 40 million hectares and forest stock increased by 1.3 billion cubic metres compared to 2005. This is China's independent action in accordance with its national conditions, and it is China's great efforts to respond to climate change globally.

Remember to adopt it.

1) CO2G) vs. H2

g) reaction to generate CH3

OH (g) and H2

o(g) From the data in the table, it can be seen that the concentration of hydrogen does not change from 10 min, and it is not 0, so it is a reversible reaction The reaction equation is CO2

3h2<>

ch3oh+h2

o From the data in the table, it can be seen that the initial concentration of hydrogen is and the equilibrium concentration is, so the amount of hydrogen participating in the reaction is.

So the heat emitted by the reaction of 3mol of hydrogen is 3mol

So then the above reaction of CO2

3h2<>

ch3oh+h2

The heat of reaction of o h=-49kj mol

From the data in the table, it can be seen that within 10 minutes c(h2, so v(h2

min) rate is equal to the ratio of stoichiometric numbers, so v(CH3OH)=1

v（h2min）=?min), so the answer is: CO2

3h2<>

2) A. The reaction is an exothermic reaction, the temperature is raised, and the equilibrium moves to the direction of the reverse reaction, and C(CH3

oh) decreases, c(CO2

enlarged, so c(ch

oh)c(co

decreases, so a is wrong;

B. Fill AR to increase the pressure, the volume is unchanged, the concentration of the reaction mixture is unchanged, and the equilibrium does not move so C(CH

oh)c(co

unchanged, so B is wrong;

c. Equivalent to the beginning of the charge of mol CO2

and mol H2

The volume becomes the original multiple, and after equilibrium, the volume is compressed to the original volume The pressure is increased and the equilibrium moves in the direction of the volume decrease, that is, it moves towards the positive reaction, c(ch3

OH) increased, C(CO2

decreased, so c(ch

oh)c(co

enlarged, so c is correct;

d. Separate the water from the equilibrium system, the concentration of the product decreases, and the equilibrium moves towards the positive reaction C(CH3

OH) increased, C(CO2

decreased, so c(ch

oh)c(co

enlarged, so d is correct

Therefore, CD;

3) From the data in the table, it can be seen that the initial concentration of hydrogen is, so a=

According to the three-stage formula, the concentration change of each component and the concentration of each component at equilibrium can be obtained, and the starting concentration of hydrogen can be seen from the data in the table, so the initial concentration of carbon dioxide is also, and the hydrogen concentration at equilibrium is, for the reaction CO2

o(g) start (mol l): 0 0

Change (mol l):

Equilibrium (mol l):

So the equilibrium constant k=c(ch

oh)?c(h

o)c(co?ch

So the answer is: 4mol;;

4) From the calculation of (3), it can be seen that the initial concentration of carbon dioxide and hydrogen is the equilibrium concentration of hydrogen, and the equilibrium concentration of carbon dioxide is.

By the equation CO2

Global warming is a common concern of all mankind There are two main reasons for climate warming: In production and life, human beings burn a large amount of coal, oil, etc., emit carbon dioxide greenhouse gases, absorb heat, and cause global temperature to rise; With the rapid growth of the global population, in order to meet the needs of the new population, people have cut down a large number of forests and reclaimed grasslands, reducing the absorption of carbon dioxide by forests, increasing the content of carbon dioxide in the atmosphere, and increasing the temperature Combined with the theme, the cultivation of fields around lakes has no effect on slowing down global warming

Therefore, c
