The annual data on coral cover for the Great Barrier Reef, produced by the Australian Institute of Marine Science, was released on Monday showing the amount of coral on the reef is at record high levels.
Record high, despite all the doom stories by our reef science and management institutions.
Like all other data on the reef, this shows it is in robust health. For example, coral growth rates have, if anything, increased over the past 100 years, and measurements of farm pesticides reaching the reef show levels so low that they cannot be detected with the most ultra-sensitive equipment.
This data is good news. It could hardly be better. But somehow, our science organizations have convinced the world that the reef is on its last legs. How has this happened?

Following on from the record-smashing cold that infected Southern Africa on Thursday, the SA Weather Service (SAWS) has confirmed that a further 19 low temperature records were broken in the past 24 hours alone.
The service had warned that the country to brace for the coldest night of the year; however, it turned out to be the coldest night in recorded history for many locales, with records set 20, 40 and even 60+ years ago falling by the wayside.
Below I’ve compiled a few of the fallen records:
Kroonstad logged a bone-chilling -8C (17.6F), toppling the city’s previous record of -7.7C (18.1F) set in 1990.
Warden’s all-time low from 1989 was beaten by 0.4C, and now stands at -6.7C (19.9F).
In Kimberly, a historic -9.9C (14.2F) was recorded.
Warmbad Towoomba’s –5.6C (21.9F) busted the previous low of -5.5C (22.1F) from 1964 (solar minimum of cycle 19).
While in Johannesburg, a reading of -7C (19.4F) smashed the old record of -6.3C (20.7F) set in 1995 (solar minimum of cycle 23).

We hear the message all the time from the German mainstream media and climate alarmists: Weather extremes are becoming more and more frequent, as the recent flood shows.
But a recent paper titled “Frequency Trend Analysis of Heavy Rainfall Days for Germany” by Deumer et al (2020) tells a very different story.
Hat-tip: Axel Bojanowski.
The two scientists from the renowned Leibnitz research network analyzed data and found no significant trends for the whole of Germany in terms of heavy rainfall.
Climate change is expected to affect the occurrence of heavy rainfall. We analyzed trends of heavy rainfall days for the last decades in Germany. For all available stations with daily data, days exceeding daily thresholds (10, 20, 30 mm) were counted annually. The Mann–Kendall trend test was applied to overlapping periods of 30 years (1951–2019). This period was extended to 1901 for 111 stations. The stations were aggregated by natural regions to assess regional patterns. Impacts of data inconsistencies on the calculated trends were evaluated with the metadata and recent hourly data. Although the trend variability depended on the chosen exceedance threshold, a general long-term trend for the whole of Germany was consistently not evident. After 1951, stable positive trends occurred in the mountainous south and partly in the northern coastal region, while parts of Central Germany experienced negative trends. The frequent location shifts and the recent change in the time interval for daily rainfall could affect individual trends but were statistically insignificant for regional analyses. A case study supported that heavy rains became more erosive during the last 20 years. The results showed the merit of historical data for a better understanding of recent changes in heavy rainfall.”
