Rising sea levels will swallow major coastal cities, not just "beach homes". Entire island nations will cease to exist. Acidifying oceans are destroying marine ecosystems necessary for generating food and oxygen for the rest of the planet. Rising temperatures might cause the release of frozen methane from ocean floor deposits and arctic permafrost. Methane accelerates greenhouse warming. Melting ice could dilute the salt balance that drives major ocean currents and plunge Europe into an ice age while the planet bakes. People are alarmed because the Titanic of society is cruising calmly toward an iceberg, and it takes an awfully long time to change direction, and no amount of technological advancement can swallow trillions of dollars in floods, droughts, famines, and barren seas.
