As Climate Dangers Rise, Scientists Predict Disasters Before They Happen

  • IPCC has warned of more frequent heatwaves, droughts and extreme rainfall
  • It’s not just enough to forecast, we really need to act: Expert from IPCC
  • Climate change puts food security at increasing risk: IPCC

For climate scientists reviewing a Pacific Ocean temperature forecast map in November, a bright red, sideways “V”, thousands of kilometres long signalled disaster. Combined with La Nina cooling in the central and eastern Pacific, the V-shaped pattern of warm sea water, stretching from Australia’s east coast to the Philippines and back over the ocean north of Hawaii, indicated that halfway around the world in the Horn of Africa the upcoming March-May rainy season would likely fail.

The scientists’ organization, called Famine Early Warning System Network or FEWS Net, sent out an alert with U.N., EU and African institutions, saying the “unprecedented” drought would likely “cause a perilous and disruptive humanitarian disaster”.

If the warning is born out, it could push the region into its worst drought on record. Millions of people would struggle to feed themselves.

Such warning systems are becoming increasingly essential as climate change puts food security at increasing risk. “Our work is to save lives and livelihoods,” said FEWS Net agricultural meteorologist Gideon Galu said in Kenya.

On Monday (February 28), a report by the U.N.’s Intergovernmental Panel on Climate Change, the top global climate science authority, warned heatwaves, droughts and extreme rainfall would become more frequent in coming decades as temperatures continue to climb.

Already, “increasing weather and climate extreme events have exposed millions of people to acute food insecurity and reduced water security,” it said.

In East Africa, FEWS Net’s team says only two biannual rainy seasons since late 2016 were considered “normal”, while the rest were wet to the point of flooding or dry to the point of drought.

Following FEWS Net’s Dec. 1 warning on East Africa, aid groups started scrambling for funding and supplies.

“It’s not just enough to forecast, we really need to act,” said Zinta Zommers, an IPCC report review editor who works at the U.N. Office for the Coordination of Humanitarian Affairs.

Acting Fast

FEWS Net began in 1985 following the Ethiopian famine. The U.N. has run a similar programme known as GIEWS for decades, while other agencies including the World Food Programme have experts regularly analysing conditions.

As climate science and satellite monitoring have improved, those tools are increasingly used as the first step in heading off climate-related catastrophe.

The 2015 Paris Agreement on climate change lists such systems as a tool to minimize loss and damage from extreme weather events, such as drought, heatwaves, locust swarms, storm surges and wildfires. Systems can even predict when winds will be strong enough to rip the roofs off houses.

FEWS Net now works in 29 of the world’s most food-insecure countries, generating crisis risk maps three times a year.

The network’s sole funder, the U.S. government’s Agency for International Development (USAID), uses its research to decide where and how to allocate aid, said Tracy O’Heir, the East Africa chief for USAID humanitarian assistance. Last year, the agency’s aid spending totalled $8 billion.

It has given early warning on events including flooding that is becoming increasingly common in South Sudan. In response to the current East Africa drought alert, following three failed biannual rainy seasons, USAID plans to fund searches for alternative local water sources or to bring in water trucks.

Locals struggling to feed themselves as cattle die of thirst and crops fail will receive stipends to buy food or dried foodstuffs shipped into the area.

The Red Cross, meanwhile, has begun using warning systems for “forecast-based financing”, with aid payments issued automatically when certain forecasting conditions are met.

We can make more use of the same amount of humanitarian support to help more people if we act before, rather than clean up afterwards, said Maarten van Aalst, director of the Red Cross Red Crescent Climate Centre.

In the Philippines – among countries most vulnerable to tropical storms – automatic payments will go out when a typhoon is predicted to destroy at least 10% of houses in at least three municipalities. Similar set-ups exist for Peru, Vietnam, Bangladesh, Mozambique and Mongolia.

‘What Will You Eat?’

Last month, Bernard Mbithi set to tearing out a failed corn crop from his field in eastern Kenya.

“What will you eat? How will you even survive? That is a major thing you have to ask yourself,” said 63-year-old Mbithi, who is married with two children. He learned about the poor forecasts for this year’s rains on his mobile phone, and decided to try planting more drought-tolerant cowpeas instead.

But warning systems, even when they work correctly, won’t be a cure-all for regions hit by climate change, scientists warn.

I’m afraid we just kind of tell them, ‘Put the Band-Aid here’. We’re not solving the big problem, the long-term problem of climate change, said Jim Verdin, programme manager for FEWS Net.

A U.N. report last year found that 58 developing countries collectively need about $70 billion per year through 2030 to adapt to climate change. So far rich countries have mobilized only $20 billion annually for these efforts, according to the Organisation for Economic Co-operation and Development. They pledged at the U.N. climate summit in Glasgow last year to double that figure by 2025.

Mr Mbithi said people need help urgently, for example with keeping livestock alive during extreme weather episodes.

“We need a lot – a lot of education to people, a lot of resources,” Mr Mbithi said.

Everywhere in the world you see that there is climate change. So you have to be worried.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ populationindigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
