Climate Reality Check

Warming of 1.5°C is likely by 2030, with far worse to follow unless governments act urgently at emergency scale to prevent catastrophe. This reality check contains 20 insights into science, impacts, risks and solutions.

Climate Risk and the Case for Emergency Action

The likelihood of rapid and escalating global warming presents a stark and urgent reality. This report warns that 1.5°C of global warming is likely by 2030, regardless of current actions, with 2°C probable before 2050 and up to 5°C possible by century’s end. The current 1.2°C of warming is already dangerous; higher levels will bring extreme, potentially unliveable conditions.

Even strong emissions cuts will not significantly slow warming over the next 20–25 years due to the masking effect of aerosols. A tipping point toward irreversible, self-sustaining “Hothouse Earth” conditions may be triggered between 1.5–2°C — and may already be unavoidable.

This report calls for emergency-level action: treating climate disruption as the highest political priority, reaching zero emissions by 2030, scaling up carbon drawdown, and exploring safe near-term cooling strategies. Only this level of commitment can protect society and nature.
