Isn t the weather much warmer now than before?

yes, you found out too! The weather is indeed getting warmer now!

After January, after the beginning of spring on February 4, the weather warmed up, and the weather became completely warmer after Qingming.

Taking Shanghai as an example, the historical weather in 2019:

January: Average High Temperature: 9, Average Low Temperature: 4;

February: Average High Temperature: 9 Average Low Temperature: 5 ;

March: Average High Temperature: 16 Average Low Temperature: 9 ;

April: Average High Temperature: 22 Average Low Temperature: 14 ;

May: Average High Temperature: 26 Average Low Temperature: 18 ;

June: Average High Temperature: 29 Average Low Temperature: 22 ;

July: Average High Temperature: 31 Average Low Temperature: 25 ;

August: Average High Temperature: 32 Average Low Temperature: 26 ;

September: Average High Temperature: 28 Average Low Temperature: 22 ;

October: Average High Temperature: 24 Average Low Temperature: 18 ;

November: Average High Temperature: 18 Average Low Temperature: 13 ;

December: Average High Temperature: 12 Average Low Temperature: 7.

Summary. Because the sky has been clear in recent days, the air is dry, and the radiation of the clear sky is relatively strong, so the temperature has risen rapidly. In particular, the influence of cold air in North China, Huanghuai and other places is scarce, coupled with warm advection transport, so there is a rare warm situation.

Why is the weather so warm this year?

Because the sky has been clear in recent days, the air is dry, and the radiation of the clear sky is relatively strong, so the temperature has risen rapidly. In particular, the influence of cold air in North China, Huanghuai and other places is scarce, coupled with warm advection transport, so there is a rare warm situation.

However, recently, the temperature difference between day and night is large, so you should pay attention to keeping warm when traveling at night.

The impact of El Niño.

Climate scientists at the National Oceanic and Atmospheric Administration (NOAA) officially announced in the latest issue of the Science and Technology Bulletin on March 12 that El Niño is back in 2015 and could be the hottest year on record.

El Niño strengthens the global warming trend.

According to the United States**, scientists published the entire process of making this judgment on their official blog.

In the past few months, scientists have observed the highest average sea level temperature ever recorded in the tropical Pacific Ocean, NOAA wrote on its blog. Observations include sea level temperatures in the Niño zone – which is thought to be an indicator of the occurrence of El Niño.

The seasonal Niño index has risen above since September last year; In recent weeks, the Niño index has risen above.

In addition, the atmospheric conditions observed by scientists also indicate that an El Niño is occurring. So after a few months, NOAA officially announced that El Niño had arrived. And this will certainly make the gradually warming world hotter.

This year's duration is likely to be longer.

El Niño transfers huge amounts of heat from the oceans to the atmosphere. So, it is conceivable that this year's El Niño, if combined with the already warming global oceans, could intensify the trend towards global warming. Another slower response to the data, the PDO (The Pacific Decadal Oscillation, also known as the "La Madre" phenomenon), also reached record-breaking levels in December and January.

And if the PDO remains elevated, it will fundamentally strengthen El Niño, potentially making 2015 the hottest year on record.

Normally, El Niño events only last 6 to 8 months, but this year's El Niño duration could increase to two years or more.

The number and amount of annual precipitation and snow are less than the average number and amount of precipitation and snow in the normal year, or the number of sunny days is more than the average number of sunny days in the year, and the number of cloudy days in the year is less than the average number of cloudy days in the normal year, which will lead to the emergence of climate anomalies.

The global recovery, we must take care of environmental protection!

Now some people keep saying that the global climate is warming, in fact, this is a one-sided view, in fact, the global climate is not getting hotter and hotter, but is becoming a climate temperature difference is getting bigger and bigger, and the summer high temperature area is expanding; In winter, the low temperature area expands, and the high temperature value is getting higher and higher. The low temperature values are getting lower and lower. What is the reason for this?

We know that the planetary phase is a process in which the solid outer shell of a planet is constantly expanding, and the surface layer of gaseous and liquid matter is constantly decreasing. The first planets were in the form of Jupiter's outer layers with extremely thick atmospheres. In the middle stage of a planet like the Earth, the atmosphere gradually becomes thinner, and the climate on the planet's surface changes more and more cold and dry, and in the later stage of a planet like the Moon, the atmosphere disappears, and the temperature difference on the planet's surface can reach several hundred degrees Celsius.

Why has the Earth's climate changed rapidly in the past 100 years? Because of the large use of oil and coal in industrialization, the chemical reaction produced by combustion turns the oxygen in the atmosphere into carbon dioxide, so the water vapor content in the atmosphere decreases, the outermost ozone layer becomes thinner, the air transparency increases, and the light and heat can easily reach the surface, and at the same time, it is easy to be lost to the air, just like we replace the thick quilt with a thin quilt, as a result, the maximum temperature in summer is getting higher and higher; In winter, when there is less light and heat, the minimum temperature will be lower and lower, and this trend of climate change will continue in the future.

There is no need to make a fuss about greenhouse gas emissions, the climate change caused by such emissions does not play a decisive role in the evolution of the earth, and even if we humans do not use those oils and coals, they cannot change the fact that they are part of the earth's constituent materials, and sooner or later they will be emitted into space in the eruption of materials inside the earth.

Yes, at least at the North and South Poles, the South Pole broke the record for extreme heat on Christmas Day.

Industry is becoming more and more developed, and more and more greenhouse gases are emitted, which will warm the earth

Sea surface temperature, also known as sea temperature, is the water temperature of the surface layer of seawater. It is often denoted by . It depends on the heat budget of the seawater. It has a pronounced diurnal and seasonal variation. **Image courtesy of ESA Climate.

Carbon dioxide, a variety of other greenhouse gases, is produced when people burn fossil minerals to generate energy or when they cut down forests and burn them.

And it is precisely because of the excessive carbon dioxide emissions that it has led to the greenhouse effect and global warming. and a hand of some extreme weather appeared.

If we don't control greenhouse gas emissions, we will protect the natural environment of the earth.

Then as the temperature of pure staring continues to rise, the glaciers at the poles will melt, and the sea water **.

I'm afraid the world in the movies "The Day After Tomorrow" and "Water World" is not far from us.

1. Human factors, human beings burn coal, oil, etc., releasing a large amount of precipitated carbon dioxide into the atmosphere, and the greenhouse effect of climate warming;

2. Natural factors. It is currently in the transition period from the glacial to the interglacial period, and the climate is gradually warming.

Because there are more and more people on the earth, and then there is more carbon dioxide ... And so on.

There are many reasons, I think there are more human factors.
