More drastic action is necessary---current rolled-out tech and policies are insufficient.

Today, thanks to rapid growth in clean energy, humanity has started to bend the emissions curve. Current policies put us on pace for roughly 3 degrees Celsius of warming by 2100 — a better result, but still devastating.
Many countries have vowed to slash emissions even faster. So far those promises exist mostly on paper, but if nations follow through, the world could potentially limit total warming to around 2 to 2.4 degrees Celsius by 2100.
Yet scientists and world leaders increasingly say even that much warming is too risky. To hold global temperature rise to a safer limit of 1.5 degrees Celsius, far more drastic action is needed.
