We can't stop rivers and groundwater from being drained faster than they refill.
open
Global / Unspecified, Global
Many major rivers and aquifers are being pumped or diverted faster than rainfall can replenish them, threatening long-term water security. Without better management, some regions may simply run out of accessible fresh water.

We don't have a fair way to relocate people displaced by rising sea levels.
open
Global / Unspecified, Global
Entire island nations and coastal communities face losing their homes permanently, with no agreed international process for where they go or who helps pay for it. This is already happening, not just a future risk.

We haven't built cities that can absorb floodwater instead of being destroyed by it.
open
Global / Unspecified, Global
Paved surfaces send rainwater rushing into drains that quickly overflow during storms, instead of letting it soak into the ground. Cities designed to absorb water naturally would suffer far less flood damage.

We can't track and reduce methane leaks from oil and gas infrastructure worldwide.
open
Global / Unspecified, Global
Methane is a far more potent greenhouse gas than carbon dioxide in the short term, and much of it leaks unnoticed from pipelines and wells. Better detection and faster repairs could meaningfully slow near-term warming.

We don't have crops resilient enough to survive increasingly unpredictable weather patterns.
open
Global / Unspecified, Global
Droughts, floods, and shifting seasons are making traditional farming less reliable in many regions. Crops that can handle this unpredictability are essential to keeping global food supply stable.

We haven't found an affordable substitute for cement that doesn't release as much carbon.
open
Global / Unspecified, Global
Cement production alone accounts for a huge share of global carbon emissions, yet it remains central to nearly all construction. A low-carbon alternative that's just as strong and cheap would be one of climate policy's biggest wins.
Citation ID: WS00050
Title: We haven't found an affordable substitute for cement that doesn't release as much carbon.

We can't rebuild coral reefs fast enough to keep pace with ocean warming.
open
Global / Unspecified, Global
Coral bleaching events are becoming more frequent as ocean temperatures rise, and restoration efforts are still small and slow. Without faster recovery methods, many reef ecosystems may not survive this century.

We don't have a way to stop wildfires from growing more frequent and destructive each year.
open
Global / Unspecified, Global
Hotter, drier conditions combined with decades of fire suppression have left forests primed to burn catastrophically. Managing this risk needs new approaches to land management, not just faster firefighting.

We haven't figured out how to farm seafood without collapsing wild fish populations.
open
Global / Unspecified, Global
Fish farming was supposed to relieve pressure on wild fisheries, but many farms still rely on wild-caught fish for feed. A truly sustainable seafood system would need to break that dependency entirely.
Citation ID: WS00047
Title: We haven't figured out how to farm seafood without collapsing wild fish populations.

We can't cool cities enough to protect people during increasingly severe heat waves.
open
Global / Unspecified, Global
Concrete and asphalt trap heat, turning cities into dangerous hot zones during extreme weather, especially for people without air conditioning. Redesigning cities to stay cooler is now a matter of public safety, not comfort.

We don't have a global system to fairly share the cost of climate damage between rich and poor nations.
open
Global / Unspecified, Global
Wealthy nations have historically emitted the most greenhouse gases, but poorer nations often suffer the worst climate damage. Without a fair cost-sharing system, climate justice remains mostly a talking point rather than a policy.

We haven't solved how to recycle batteries and electronics without toxic waste byproducts.
open
Global / Unspecified, Global
Current recycling methods for batteries often use harsh chemicals or produce hazardous waste of their own. A cleaner recycling process would make the growing battery industry far more sustainable.

We can't yet track and stop illegal deforestation as it happens in real time.
open
Global / Unspecified, Global
By the time illegal logging is discovered, the trees are often already gone and the damage is done. Real-time detection and enforcement could protect forests before, not after, they disappear.

We don't have a reliable way to desalinate seawater cheaply enough for widespread drinking use.
open
Global / Unspecified, Global
Turning seawater into drinking water is technically possible but still too energy-intensive and expensive for many water-scarce regions. Cheaper desalination could solve water shortages for millions of people.

We haven't found a way to farm food without depleting the soil that grows it.
open
Global / Unspecified, Global
Modern farming often strips soil of nutrients faster than nature can replace them, threatening long-term food production. A farming method that restores rather than depletes soil could secure food supply for generations.
Citation ID: WS00041
Title: We haven't found a way to farm food without depleting the soil that grows it.

We can't stop plastic waste from accumulating in oceans faster than we clean it up.
open
Global / Unspecified, Global
Millions of tons of plastic enter the ocean every year, and cleanup efforts remove only a small fraction of it. Without cutting the source and scaling removal, marine ecosystems will keep absorbing the damage.
Citation ID: WS00040
Title: We can't stop plastic waste from accumulating in oceans faster than we clean it up.

We don't have affordable technology to remove carbon dioxide from the atmosphere at meaningful scale.
open
Global / Unspecified, Global
Direct air capture exists, but it's still far too expensive and energy-intensive to make a dent in global emissions. Making it cheap enough to scale is one of the biggest levers left for slowing climate change.

We don't have a widely trusted way to prove a person online is actually a real human.
open
Global / Unspecified, Global
As AI-generated accounts and bots flood social platforms, telling a real person from an automated one is getting harder. Without a trusted verification method, online trust and public discourse both suffer.

We haven't built translation technology that fully preserves tone, culture, and nuance across languages.
open
Global / Unspecified, Global
Machine translation is fast and often accurate, but it still misses jokes, idioms, and cultural context that change meaning entirely. Real cross-cultural communication needs more than word-for-word accuracy.

We can't guarantee that personal data, once deleted, is truly gone from every system that touched it.
open
Global / Unspecified, Global
Data gets copied, backed up, and shared across so many servers that a single delete request rarely removes every trace. Real digital privacy requires a technical guarantee that deletion actually means deletion.
