How can you manage a dam, a flood, or a hydroelectric plant if you have no information or data?
You can’t.

#COP30 in extra day - Adaptation finance is nowhere near what vulnerable nations need. This is the red line for LDCs. We need strong LDC Fund replenishment & a commitment to triple adaptation finance by 2030. Immediate 1.5 °C action required.

We cannot air condition our way out of the heat crisis.
Many cooling methods add planet warming emissions, in-turn increasing cooling demand.

All nations committed under the Paris Agreement to limit global warming to 1.5 degC for good reason. Instead many governments are beholden to the fossil fuel lobby and even subsidize fossil fuel use with your money. We’re now at 1.4 degC & emissions are rising not falling.
