- This weekly round-up contains the key nature and climate news from the past week.
- Top nature and climate stories: Global reservoir levels decline despite construction boom; More than 180,000 people in India and Pakistan flee cyclone Biparjoy; EU records highest ever average world temperature for early June.
1. Global reservoir levels decline despite construction boom
Water levels in the world’s reservoirs fell during the last two decades, even though a construction boom increased global water storage capacity, new research shows.
Satellite data from more than 7,200 reservoirs worldwide shows a drop in water levels between 1990 and 2018, despite a 28 cubic kilometre annual storage capacity increase.
The findings of the study, published by Nature Communications, suggest new dams alone will not be enough to resolve the world’s increasing water stress threat.
While climate change was identified as a “critical factor” in falling water levels, increasing water demand also contributed.
“Even if temperatures stop rising, increasing demand and new construction are likely to continue,” lead author Huilin Gao of Texas A&M University, told Reuters.
The Global South saw the biggest declines in water storage levels, particularly countries in Africa and South America. This is due to a combination of rising water demand and newly constructed reservoirs failing to fill to expected levels.
Increased frequency, duration and intensity of severe droughts has brought the feasibility of large-scale reservoirs into question.
However, the International Hydropower Association said new dams and reservoirs are a crucial part of efforts to mitigate increasing climate extremes.
Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum’s Global Risks Report continues to rank these environmental threats at the top of the list.
To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.
The World Economic Forum’s Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.
This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

2. More than 180,000 people in India and Pakistan flee cyclone Biparjoy
A major evacuation effort has helped hundreds of thousands of people to safety as cyclone Biparjoy made landfall in western India on 15 June.
More than 180,000 fled from the approaching category one storm, which has brought sustained winds of up to 125 kilometres per hour. So far no casualties have been reported.
The cyclone could cause tidal waves in the Arabian Sea of up to 3 metres in height, capable of inundating low-lying coastal areas of both nations, according to the India Meteorological Department.
Over 100,000 people have been evacuated from eight coastal regions in the Indian state of Gujarat, and 82,000 people from high-risk coastal areas in Pakistan, authorities report.
Temporary shelters were set up in schools and other government buildings to accommodate people displaced by the storm.
The human-induced climate crisis is increasing the frequency and intensity of extreme weather events like cyclones, with an up-to four-fold increase in reported incidents between 1970 and 2022.
3. News in brief: Other top nature and climate stories this week
EU records highest ever average world temperature for early June, as temperatures exceed previous records by a “substantial margin”, Euractiv reports. This follows near-record-breaking temperature highs in May.
