The unknown thing about interactive disaster forecasting map

When the earth's temperature rises by 4 degrees Celsius, food production will decline sharply, the number of forest fires and floods . increases in many countries. These consequences have been concretized by British meteorologists on a digital map.

On the map created by the British Government Meteorological Agency, the areas with the greatest risk are circled. The color of the circle represents each specific risk: brown - forest fire, light green - reduced yield, blue - lack of fresh water, dark green - rising sea level, light purple - produce reduced seafood, dark brown - drought; light blue - glaciers melt; dark green - tropical storm, red - high temperature, gray - diseases such as diarrhea, malaria, dengue . outbreaks.

See clearly the consequences

No longer limited to abstract forecasts, interactive maps are a scientific approach that can be applied to prevent complex weather phenomena and specific regional consequences on a global scale.

When the earth's temperature rises by 4 degrees Celsius, the output of agricultural crops in the world will fall sharply. At low latitudes, wheat and corn yields will decrease by 40%. Soybean productivity in the world's largest production regions, North America, South America and Southeast Asia, will "slow down without braking."

Meanwhile, the frequency and severity of forest fires will increase in most of the earth's forests, including North America, Latin America, South America, East Africa, Southeast Europe, Australia, Russia ( especially the part located in Europe and the Ural region).

By 2050, the glaciers in the Himalayan mountains will "shrunk" significantly. After the glaciers melt, the water supply for China's largest rivers will run out, and 23% of people in the world's most populous country will suffer from a shortage of drinking water.

India is also severely affected because its rivers receive 70% of the water from the glacier in the mountains. Freshwater resources in the Mediterranean, southern Africa and large areas of South America, which are supplemented by glaciers in the Cordillera range, are likely to be reduced by up to 70%.

The same fate awaits polar ice caps. In North Siberia, Canada and Alaska, the surface layer of the permanently frozen land will completely dissolve, causing serious consequences for plants and animals as well as infrastructure. According to scientists' calculations, temperatures rising 4 degrees C will also melt ice in the West of Antarctica and Greenland.

All of this melting will increase sea level and sea level significantly. Tropical storms will appear regularly with greater intensity. As a result, the risk of death is high for many European countries and coastal regions of other countries.

Asian residents become . fish

By the end of this century, sea level could rise by 80 cm and will continue to increase. Sea levels in tropical latitudes will be much higher. Just adding 53 cm of extra water, another 150 million people have to live in flooded areas, first of all in the Pacific and Indian Ocean regions, three-quarters of whom are Asian residents. About 56 million people along the Indian Ocean, 25 million along the coast of East Asia, 13 million people along the coast of Southeast Asia will have to live in flooding.

In addition, the rising temperature of the water will reduce the amount of dissolved oxygen in it, meaning that ocean life changes completely with the destruction of many seafood species.

The above consequences are predicted by scientists when the average average temperature of fruits increases by only 4 ^° C. What will human life be like when their prediction comes true?

Climate change in East Asia and the Pacific

The World Bank's 2010 World Development Report highlights three key factors that make people in East Asia and the Pacific heavily affected by climate change:
- A large number of people live along the coast and on the low island: more than 130 million Chinese, nearly 40 million Vietnamese, 2 million people in the Pacific Islands .
- Some poor countries rely heavily on agriculture. As pressure on land, water resources and forests increases due to increased population, urbanization and environmental degradation, these countries face more and more management issues related to environmental resources.
- Regional economies still depend on aquatic resources. In Southeast Asia alone, the value of coral reefs is up to 13 billion USD. This area is under pressure from industrial pollution, overfishing. (Thu Loan)
