Abnormal Climate
Extreme Precipitation Regions Growing In Number and size
Abnormal Climate is due to climate factors such as temperature or precipitation indicating significantly high or low levels that have not been observed over the past 30 years or more.
The likelihood of extreme precipitation could grow fourfold in parts of Central Africa, China, and the east coast of North America compared with 1950-81.
According to climate scientists, more warming over the upcoming ten years at the very least, and probably beyond, is inevitable. Climate models predict an increase in global climate hazards with rising global average temperatures. These models conclude that continued warming will intensify chronic hazards and increase the frequency and/or severity of acute climate disasters.
Major Abnormal Climates
Heat Waves. Major American cities are seeing more heat waves than in the past. Six heat waves per year, compared to two in the 1960s, is a three-fold increase in frequency. Individual heat waves are lasting longer and getting more intense, and the average heat wave season is 49 days longer.
Heavy Precipitation. In the United States, a greater proportion of precipitation has lately taken the form of severe one-day events. Between 1910 through the 1980s, the frequency of extreme single-day precipitation occurrences stayed largely stable, but has since increased significantly. Since 1996, nine of the top ten years in the country for extreme one-day precipitation occurrences have taken place. Atypically high annual precipitation totals have become more frequent.
River Flooding. By region, there are regional variations in the frequency and size of river flood events. The majority of the Northeast and Midwest have seen bigger floods, whereas the West, southern Appalachia, and northern Michigan have seen smaller floods. In the Northeast, Pacific Northwest, and portions of the northern Great Plains, large floods have increased in frequency, whereas they have decreased in frequency in the Southwest and the Rockies.
In China
Many people suffered from a record-breaking
heatwave from June to August
+
The Yangtze River basin
Worst drought
- 80% less rain than the 30-year average/ 2 to 4 degrees higher than average
Poyang lake (the largest freshwater lake in China)
A drop in water level
-From 19 metres in June to 9 metres by the end of August
In Pakistan
Heavy rain has caused a lot of damage (over 3 to 4 times as much as rain) from June to September
+
Floods- over 1,300 deaths/ over 1.1 million homes, bridges, and roads damaged/ lost over 800,000 livestock = It affected 15% of the country
In Chile
High temperatures and rainstorms affected negatively
+
In Patagonia
-glaciers collapsed in national parks
The Cause of the Aforementioned Phenomena
