That's untrue.
It's estimated that there are roughly 20,000 species of wild bees. As far as is known, manmade climate change has not caused any species of bee (or any species of anything else) to go extinct.

The claim that "humans have destroyed 80%" of bees is a lie.
Roughly 2000 species of bees are native to Mexico. Only about 800 species of bees are native to Canada.
(What does that tell you about the supposed "threat" of 1-2° of warming?)
Domestic honeybees are not native to North America, but they are not in decline, either.

The WMO estimates that since the “pre-industrial” mid-to-late-1800s (late Little Ice Age) the Earth has warmed an average of 1.15±0.13 °C. So, what is the significance of that?
1°C is the temperature change you get from an elevation change of about 500 feet.
At mid-latitudes, 1°C is about the temperature change you get from a latitude change of about 60 miles.
1°C is less than the hysteresis (a/k/a “dead zone” or “dead band”) in your home thermostat, which is probably 2-3°F. Your home's “constant” indoor temperatures are continually fluctuating that much, and you probably don't even notice it.
In the American Midwest, farmers can fully compensate for 1°C of climate change by adjusting planting dates by about six days.
Growing ranges for most important crops include climate zones with average temperatures that vary by tens of °C. Major crops like corn, wheat, potatoes and soybeans are produced from Mexico to Canada.
Compared to that, 1°C is negligible.
