The correct answer is: d) All of the above.
Climate change is a major threat to Bihar, as it is to many other parts of the world. The state is already experiencing the effects of climate change, including more frequent and intense heatwaves, increased flooding, and changes in rainfall patterns. These changes are having a significant impact on the people and the environment of Bihar.
Heatwaves are becoming more common and more intense in Bihar. In 2019, the state experienced its hottest summer on record, with temperatures reaching over 45 degrees Celsius (113 degrees Fahrenheit). These heatwaves are causing widespread health problems, including heatstroke, dehydration, and respiratory problems. They are also damaging crops and livestock, and disrupting the lives of people and businesses.
Flooding is also becoming more common in Bihar. In recent years, the state has experienced several major floods, including the 2017 floods that affected over 10 million people. These floods are caused by a combination of factors, including climate change, deforestation, and poor infrastructure. They are causing widespread damage to homes, businesses, and infrastructure, and displacing millions of people.
Rainfall patterns are also changing in Bihar. The state is experiencing more erratic rainfall, with longer dry spells and shorter, more intense periods of rain. This is causing problems for farmers, who are struggling to adapt to the changing conditions. It is also leading to increased soil erosion and landslides.
Climate change is a serious threat to Bihar. The state is already experiencing the effects of climate change, and these effects are only going to get worse in the future. It is important to take action to mitigate the effects of climate change and to adapt to the changes that are already happening.
