Climate change: Get ready for hotter, drier, wetter future

New Delhi: Climate change is happening, with strong evidence that the Earth is already one degree Celsius hotter than at the start of the 20th century. The past four years have been the hottest on record. All this is a foretaste of a hotter, drier and wetter future, says an international researcher.

He said climate change will continue to happen as more heat-trapping greenhouse gases and short-lived climate pollutants accumulate in the atmosphere.

“While mitigation is necessary to control climate change, adaptation is essential to face the hotter, drier, wetter future,” Kathmandu-based ICIMOD’s programme manager Arun B Shrestha told reporters.

At the Conference of Parties (COP) 21 in Paris last year, the governments agreed to “hold the increase in the global average temperature to well below two degrees Celsius above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5 degrees”.

Shrestha said these commitments are highly ambitious but the plans developed so far cannot avoid a rise of three degrees Celsius.

UN weather agency the World Meteorological Organization said in terms of global averages, each of the past several decades has been significantly warmer than the previous one.

The period 2011-2015 was the hottest on record and 2015, because of a powerful El Nino phenomenon, was the hottest since modern observations began in the late 1800s.

Along with the rising temperatures, climate change is disrupting the seasons and increasing the frequency and intensity of extreme events such as droughts and heavy rainfall.

And when it comes to the mountains, the indications are that changes will manifest in much stronger ways.

The Mountain Research Initiative, a scientific organisation that addresses global change issues in mountain regions around the world, warns that warming will be much stronger in high elevation areas, such as the Hindu Kush Himalayas, where the impact will be compounded by biophysical fragility and socio-economic vulnerability.

Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD), along with its partners, has been conducting scientific research on climate change to support policy and action to reduce climate impacts and vulnerabilities.

According to a climate and water atlas, “Mapping an uncertain future: Atlas of climate change and water in five crucial water basins in the Hindu Kush Himalayas”, the mountain range extending west of the Himalayas are warming significantly faster than the global average.

The atlas, published last year by ICIMOD, and two Norwegian entities – GRID-Arendal and the Centre for International Climate and Environmental Research (CICERO) – said the temperatures across the Hindu Kush will increase by about one to two degrees Celsius, in some places by four to five degrees, by 2050.

The atlas also warns that precipitation will change, with that in summer increasing in most parts of the region. The number of rainfall events is expected to decrease, but with more water falling during each event, causing both floods and droughts.

The Hindu Kush Himalayan region is home to 210 million people and provides water to over 1.3 billion people – more than the entire continent of Europe.

To counter mitigations of climate change, Shrestha, who is ICIMOD’s programme manager for the river basins and cryosphere and atmosphere regional programmes, said adopting climate-smart villages models, along with flexible and integrate farming with weather information is the right approach.

At the catchment scale, he said, community-based flood early warning systems like the one implemented in Assam by ICIMOD and its partners have increased the resilience of the people.

In addition to floods, droughts also need to be addressed through integrated drought management, the researcher added. (Vishal Gulati, IANS)

Women Are Rarely “Put Front And Center” At The Heart Of Climate Action

Feminism doesn't mean excluding men

Women must be at the heart of climate action if the world is to limit the deadly impact of disasters such as floods, former Irish president and U.N. rights commissioner Mary Robinson said on Monday.

Robinson, also a former U.N. climate envoy, said women were most adversely affected by disasters and yet are rarely “put front and center” of efforts to protect the most vulnerable.

“Climate change is a man-made problem and must have a feminist solution,” she said at a meeting of climate experts at London’s Marshall Institute for Philanthropy and Entrepreneurship.

“Feminism doesn’t mean excluding men, it’s about being more inclusive of women and – in this case – acknowledging the role they can play in tackling climate change.”

Research has shown that women’s vulnerabilities are exposed during the chaos of cyclones, earthquakes and floods, according to the British think-tank Overseas Development Institute.

In many developing countries, for example, women are involved in food production, but are not allowed to manage the cash earned by selling their crops, said Robinson.

The lack of access to financial resources can hamper their ability to cope with extreme weather, she told the Thomson Reuters Foundation on the sidelines of the event.

“Women all over the world are … on the front lines of the fall-out from climate change and therefore on the forefront of climate action,” said Natalie Samarasinghe, executive director of Britain’s United Nations Association.

“What we — the international community — need to do is talk to them, learn from them and support them in scaling up what they know works best in their communities,” she said at the meeting.
