🗞️ Driving the news: In his new book Shelter from the Storm, journalist Julian Hattem argues that climate migration is not happening enough
• He states that this shortage may worsen climate vulnerability rather than reduce it

🔭 The context: Climate change is drying farmlands, raising food prices, and eroding livelihoods in places like Guatemala’s “Dry Corridor”
• Yet the poorest and most climate-exposed people are often unable to migrate due to cost, legal barriers, distance, and risk. These “trapped populations” may become climate change’s most vulnerable victims

🌍 Why it matters for the planet: Migration can be a powerful climate adaptation tool
• Money sent home by migrants (remittances) helps fund flood protection, safer housing, irrigation, cooling during heatwaves, and disaster recovery
• It reduces long-term environmental damage and human loss
• Restrictive borders and dangerous routes, by contrast, increase climate risk and mortality without reducing migration pressures

⏭️ What’s next: Hattem and economists suggest governments should enable safer, legal, and even subsidised migration, including rural-to-urban moves, as part of climate adaptation policy
• This may reframe mobility as a solution, not a failure

💬 One quote: “The biggest climate migration problem may be that there’s simply not enough of it”

📈 One stat: Migrants moving from lower- to higher-income countries typically see their wages rise three to six times, according to the World Bank
