For a recent informative update from the Australian Long-term (coral) Monitoring Program see https://www.aims.gov.au/monitoring-great-barrier-reef/gbr-co.... The graphs show that Northern Barrier Reef and the Central Barrier Reef coverage have record high coral cover while the Southern Barrier Reef, "hard coral cover was relatively stable although decreased slightly to 26.4% (22.9–30.2% CIs) from 26.9% (23.0–30.9% CIs) in 2025. This represents a relative decline of 2.0% of 2025 levels, which is within the margin of error, and regional coral cover remains below the long-term average of 29.3% (27.5–31.3% CIs).". The sea surface temperatures remained 0.7–1.2°C above average across the Great Barrier Reef. The Australian Environment Foundation finds that ~80% of Australians think that the reefs are at a record low. Apparently, CO2 in 1985 was about 345.9 ppm. In 2026 it's was about 432 ppm - I haven't checked the actual Mauna Loa site.
