Climate Change Made 2011–2020 Decade Warmer And Wetter For India, Says World Meteorological Organisation
World over, glaciers thinned by around 1 metre per year with long-term repercussions for water supplies for many millions of people, the WMO report said.

Worsening climate change made the 2011-2020 decade wetter and warmer for India, a new report by the World Meteorological Organisation (WMO) released at the UN climate conference said on Tuesday.
"Compared to the state of climate reports the WMO publishes every year, the new report provides a long-term perspective and sustained trends from 2011 to 2020, which could help discern where the world is headed," WMO deputy secretary general Elena Manaenkova told PTI in an interview.
This report by WMO, the UN's weather authority, also eliminates "variations" due to factors such as El Nino or La Nina which are periods of unusual warming and cooling of the waters of the equatorial Pacific Ocean that increase the chances for above-or below-average temperature or precipitation in different parts of the world.
The year 2023 to be the warmest
The provisional annual report for 2023, released at the ongoing climate change summit (COP28) last week, said 2023 is set to be the warmest year on record. It was a "wet decade" over northwest India, Pakistan, China, and the southern coast of the Arabian Peninsula, the WMO, a specialised agency of the United Nations that covers weather, climate and water resources, said.
The occurrence of extreme warm days in the 2011-2020 period was approximately twice the 1961-1990 average in parts of southeast Asia, most of Europe, southern Africa, Mexico, and parts of eastern Australia.
Extreme cold has become less frequent with warming global temperatures: extreme cold days and nights in the 2011-2020 period were about 40 per cent below the 1961-1990 average, it said and listed examples from India among other extreme weather events.
India had the worst flooding episode in 2013
India had the worst single flooding episode in a monsoon season in June 2013, when heavy rains, mountain snowmelt, and glacial lake outbursts led to extreme flooding and landslides in Uttarakhand, killing more than 5,800 people, the report said and added, Kerala was badly affected by floods in 2018.
The years 2019 and 2020, India's two wettest monsoon seasons in the previous 25 years, saw intense and widespread flooding. Over 2000 flood-related deaths were reported in India and neighbouring countries. Droughts during the 2011-2020 decade had major socioeconomic and humanitarian impacts.
Droughts lead to severe food and water insecurity
In India, droughts lead to severe food and water insecurity; the situation was exacerbated by inequalities in water availability and access to its supply. Due to substantial crop failures (between 10 per cent and 100 per cent in the districts surveyed) the drought increased the reliance of households on India's Public Distribution System (PDS) for access to staple food grains. During this drought event, 82 per cent of households in affected areas were at risk of food insecurity.
World over, glaciers thinned by around 1 metre per year with long-term repercussions for water supplies for many millions of people, the WMO report said. The Antarctic continental ice sheet lost nearly 75 per cent more ice between 2011-2020 than it did in 2001-2010, and the resulting sea level rise will jeopardise the existence of low-lying coastal regions and states in the future, it said.
"Each decade since the 1990s has been warmer than the previous one and we see no immediate sign of this trend reversing. More countries reported record high temperatures than in any other decade," said WMO Secretary-General Petteri Taalas.
The globe's oceans are warming faster
He said the world's oceans are warming faster and the rate of sea level rise has nearly doubled in less than a generation. The world is losing the race to save the melting glaciers and ice sheets, which is unequivocally driven by greenhouse gas emissions from human activities, Taalas added.
Weather and climate-related events were responsible for nearly 94 per cent of all disaster displacement recorded over the last decade and had a major impact on the progress of global efforts to end hunger, food insecurity, and malnutrition.
The WMO said climate change is "greatly" affecting the likelihood of many extreme events. Virtually every attribution study found that the likelihood of an extreme heat event increased significantly. Heat waves were responsible for the highest number of casualties, while tropical cyclones caused the most economic damage.
It said though the number of casualties from extreme events has declined due to improved early warning systems, economic losses have increased. The 2011-2020 decade was the first since 1950 when there was not a single short-term event with 10,000 deaths or more.
The report said public and private climate finance almost doubled between 2011 and 2020. However, it needs to increase at least seven times by the end of this decade to achieve climate objectives. With the world emitting 36.8 billion metric tonnes of carbon dioxide in 2023 twice the annual volume of four decades ago, Manaenkova, attending her 17th international climate conference, said, "Let's finally get serious."
