Uttarakhand has faced climate change as well human to be equally blamed

Uttarakhand was still recovering from the tragic incident of flash floods in February following avalanches and avalanches on the Alaknanda River, now that flash floods and landslides followed by torrential rains have engulfed the state. Due to this unseasonal rain, rivers and lakes are in spate and are flowing close to the danger mark.

Although experts have already accepted a substantial increase in severe weather events, the current event has shown the effect of a prolonged monsoon. Meteorologists believe that if the monsoon had gone on time, there would not have been such a torrential rain. The presence of Monsoon Current continued to drive moist winds and weather systems over the plains.

Severe weather events are not new to the country and the frequency of these events has also increased. All the credit for this goes to climate change, which is changing its mood in India. The latest example is the torrential rains in Uttarakhand earlier this week. The weather remains calm in Uttarakhand after the withdrawal of monsoon.

The state rarely receives much rain and thundershowers. However this has not happened this season. Incessant rain started in the state from Sunday night and lasted till Tuesday. In October so far, Uttarakhand has recorded 192.6 mm of rain as against 31.2 mm. Out of this, 122.4 mm was recorded in 24 hours. Reportedly, around 52 people lost their lives due to incessant heavy rains and landslides. The worst affected district was Nainital in which 28 people died the most.

The reason for these unseasonal rains over the state is attributed to the prolonged southwest monsoon in the country in 2021. The abundance of moisture over this region due to the presence of monsoon in this region, keeping the weather conditions favorable for the formation of weather systems.

The late withdrawal of southwest monsoon has become a new normal courtesy of climate change, the latest report of the UN-led Intergovernmental Panel on Climate Change (IPCC) – ‘Working Group I the’ Sixth Assessment Report Climate Change 2021: The Physical Science Basis” has already indicated that rising global temperatures are changing monsoon patterns across Southeast Asia.

Due to the hot climate, the weather is always humid. Professor Y P Sundriyal, Head, Department of Geology, HNB Garhwal University, said, “The high reaches of the Himalayas are highly sensitive, both climatically and tectonically, so high that the construction of mega hydro-projects in the first phase should be avoided or they should be of smaller capacity.

Secondly, roads should be constructed with all scientific techniques. Presently, we see that roads are being constructed or widened without taking proper measures like slope stability, good quality retaining wall and rock bolting. All these measures can limit the damage caused by landslides to some extent.

“There is a big difference between planning and implementation. For example, rainfall patterns are changing, with extreme weather events rising temperatures”. Prof Sundriyal said that “Policy makers should be well versed with the geology of the area. The fact of development cannot be denied, but hydropower plants, especially in the higher Himalayas, should be of lesser potential. Policy and project implementation should involve local geologists who understand the area well and how it responds.

According to Mr. GP Sharma, President – ​​Meteorology and Climate Change, Skymet Weather, “It is very clear that the monsoon had gone on time, we would never have seen such torrential rains. While there was a western disturbance in the hills and two low pressure areas were observed over Madhya Pradesh and Bay of Bengal respectively.

There are indications of a delay in the withdrawal of monsoon. Normally, the weather system does not travel inland, as the NLM was still passing through Madhya Pradesh by this time, so it moves inside the low pressure area.

We have all come under the firing range of this climate change, which has completely changed the frequency, timing and path of climate change through weather systems before, during and after the monsoon. GP Sharma said, “We are in the second half of October and the weather system is still entering inside Maharashtra.”
