Sadly, a lot of people have been conned into believing that climate change is a huge conspiracy by the scientific community, to ensure continued funding for their research.
Seems this site is a magnet for conspiracy nutters, and climate denialism is fundamental to their belief systems.
This study spells out the disaster that is happening right now, the rapid destruction of the coral reefs, particularly Australia's iconic Great Barrier Reef.
But I don't expect the conspiracy nutters to waste their time actually learning anything that might throw doubt on their dearly held misconceptions.
Just a tiny part of this one study:
Sea temperatures in the tropics have increased by almost 1°C over the past 100 years and are
currently increasing at the rate of approximately 1-2°C per century. Reef-building corals, which
are central to healthy coral reefs, are currently living close to their thermal maxima......
Corals may also adapt in evolutionary time, but such changes are expected to take hundreds of years, suggesting that the quality of the world’s reefs will decline at rates that are faster than expected. Every coral reef examined in Southeast Asia, the Pacific and Caribbean show the same trend.
