Shift needed from what weather will be, to ‘what the weather will do’

13 October 2020

Extreme weather and climate events have increased in frequency, intensity and severity as a result of climate change, hitting vulnerable communities disproportionately hard, a new UN report has revealed, calling for greater investment in effective early warning systems. 

The State of Climate Services 2020 Report: Move from Early Warnings to Early Action, released on Tuesday by the UN World Meteorological Organization (WMO), underscored the need to switch to impact-based forecasting – an evolution from “what the weather will be” to “what the weather will do” so that people and businesses can act early, based on the warnings. 

Being prepared and able to react at the right time, in the right place, can save many lives and protect the livelihoods – WMO Secretary-General

“Early warning systems constitute a prerequisite for effective disaster risk reduction and climate change adaptation. Being prepared and able to react at the right time, in the right place, can save many lives and protect the livelihoods of communities everywhere,” Petteri Taalas, Secretary-General of WMO, said in a foreword to the report. 

He also highlighted that while it could take years to recover from the human and economic toll of the COVID-19 pandemic, it is crucial to remember that climate change will continue to pose an on-going and increasing threat to human lives, ecosystems, economies and societies for centuries to come. 

“Recovery from the COVID-19 pandemic is an opportunity to move forward along a more sustainable path towards resilience and adaptation in the light of anthropogenic climate change,” added Mr. Taalas. 

Challenges in small islands, developing countries 

Globally over the past 50 years, some 11,000 disasters, attributed to weather, climate and water-related hazards, claimed over 2 million lives and cost the world economy $3.6 trillion, according to WMO. 

In 2018 alone, storms, floods, droughts and wildfires left some 108 million people in need of international humanitarian assistance. By 2030, this number could increase by almost 50 per cent at a cost of around $20 billion a year. 

In spite of the alarming figures, one in three people are still not adequately covered by early warning systems, with communities in Africa, least developed countries and small island developing States most affected, the UN agency added, citing challenges such as weak dissemination of early warning, inadequate observing networks, and insufficient capacity to translate early warning into early action.

Making early warning systems more effective 

The report outlines six key recommendations to improve the implementation and effectiveness of early warning systems, globally: 

  • Investing to fill the early warning systems capacity gaps, particularly in African least developed countries and small island developing States; 
  • Focusing investment on turning early warning information into early action; 
  • Ensuring sustainable financing of the global observing system that underpins early warnings; 
  • Tracking finance flows to improve understanding of where these resources are being allocated in relation to early warning systems implementation needs and what impact this is having; 
  • Developing more consistency in monitoring and evaluation to better determine early warning systems effectiveness; and 
  • Filling data gaps, particularly in small island developing States.
