What are the consequences of global warming?

The hot weather on the earth does not mean that Miami's lifestyle will be in line with Africa's, but it does lead to the rise of sea level. How does high temperature weather cause sea level rise? It turns out that too high a temperature will cause icebergs to melt. The continuous melting of sea ice and polar ice sheets has increased the amount of water in the ocean, leading to the rise of sea level.

If the beach is flooded, people will lose a lot of fun. At present, many cities like Miami in the world are facing the threat of rising sea level.

Scientists can measure the impact of the melting of the Greenland ice sheet: the flow of the Colorado River has increased sixfold. Scientists predict that if the ice shelves in Greenland and Antarctica continue to melt, the sea level will be 6 meters higher than it is now by 2 100. This will inundate many Indonesian tropical islands and low-lying areas, as well as Miami, new york City, Manhattan and Bangladesh.

2. Melting glaciers

No special equipment is needed to observe whether glaciers are melting. After the frozen soil that was originally covered on the tundra surface melted due to the increase of surface temperature, vegetation is now growing on it.

Due to the rising surface temperature, Montana's National Glacier Park has lost many magnificent scenery.

In this century, the glaciers in Montana National Park have been seriously reduced. In addition, Himalayan glaciers are the main source of Ganges water. The Ganges provides drinking water and irrigation water for 500 million people. It is said that the annual water consumption is decreasing at the rate of 37 meters.

3. The heat wave is coming

In 2003, the deadly heat wave that swept across Europe killed about 35,000 people, which may be a precursor to the hot summer trend that scientists began to track at the beginning of the 20th century.

Heat wave will not only inhibit some functions of human body, but also cause death. The picture shows a man trying to cool down by pouring water from a bottle on the street of new york hit by a heat wave in 2008.

In the last 50 years to 100, the frequency of extremely hot heat waves is two to four times higher than usual. It is predicted that it will be higher than 100 times in the next 40 years. Experts predict that the continuous heat wave will lead to an increase in the frequency of fires and related diseases and an increase in the average temperature of the earth.

4. Storm and flood

Experts use climate models to predict that global temperature rise will have an impact on precipitation. But the increasingly frequent mega-storms really don't want to be seen by anyone: in just 30 years, the frequency of strong hurricanes of magnitude 4 to 5 has almost doubled.

Warm sea water increases the possibility of strong storms. In July 2008, Hurricane Dolly swept across the border between Texas and Mexico.

The warm sea water provided strength for the hurricane. Scientists relate the temperature of the ocean and atmosphere to the possibility of strong storms. In the past few years, the United States and Britain have been hit by super storms and floods, many people have died and property losses have reached hundreds of millions of dollars. From 1905 to 2005, the frequency of hurricanes increased steadily. Between 1905 and 1930, there are about 3.5 hurricanes every year on average; 193 1 year to 1994, with an average of about 5. 1 time per year; Between 1995 and 2005, there were 8.4 hurricanes every year on average.

5. Drought

When some parts of the world are hit by storms and floods, others are threatened by drought. With the climate warming, experts estimate that the drought may increase by at least 66%, which will lead to the shrinking of water supply and the decline of crop production quality. This puts global food production and supply in danger, and people are increasingly at risk of being threatened by hunger.
