Klima-løgne

Problemet er jo slet ikke forskerne.
Hvis argumentationen holder, så vil skolelærere dumpe børn, for at få flere elever, læger, vil erklære folk syge, selvom de er raske, og tandlæger vil hive raske tænder ud.
Altsammen blot for at sikre sig selv.

Problemet er menneskets ensidige udnyttelse af jordens ressourcer, der nu fører til øgede temperaturer overalt på kloden, herunder også ødelæggelse af koralrev, forsuring og iltsvind i oceanerne, mere ekstremnedbør, flere og længere hedebølger, højere vandstand, flere oversvømmelser.
Alt er målbart, det sker, og det bliver kun mere og mere i fremtiden. Ikke pga forskere, men pga utallige stivstikkere, der i årevis har bildt sig selv ind, at et ændret klima ikke får konsekvenser for menneskeheden.

Jeg taler om virkeligheden, her i EU.

Selvfølgeligt vil en kraftig nedsættelse af CO2 udledningerne føre til, at atmosfærens indhold af CO2 stiger langsommere.
Derfor kan havstigninger, værre hedebølger mv afværges.
Det er indlysende.

Millioner og atter millioner er afhængige af indtægter skabt af sunde og utroligt facinerende koralrev.

Europa 2003, den værste hedebølge i århundreder rammer.
Flere end 70.000 dør som følge af for høje temperaturer.

Fremtiden med højere temperaturer byder på flere og længerevarende hedebølger.

Varmen er det, der skader koralrev.

Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.

In 2005, the U.S. lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event. The warm waters centered around the northern Antilles near the Virgin Islands and Puerto Rico expanded southward. Comparison of satellite data from the previous 20 years confirmed that thermal stress from the 2005 event was greater than the previous 20 years combined.

Not all bleaching events are due to warm water.

In January 2010, cold water temperatures in the Florida Keys caused a coral bleaching event that resulted in some coral death. Water temperatures dropped 12.06 degrees Fahrenheit lower than the typical temperatures observed at this time of year. Researchers will evaluate if this cold-stress event will make corals more susceptible to disease in the same way that warmer waters impact corals.

Analyses of coral bleaching on Caribbean reefs over the past two decades suggests that small increases in regional sea surface temperature (0.1 °C) result in large increases in the geographic extent and intensity of coral bleaching events. Given that climate change models suggest an increase in sea surface temperatures of 1–3 °C over the next 50–100 years, coral bleaching events may become an intense, annual stress on coral reefs throughout the Caribbean and even the world. Although corals may adapt and their bleaching thresholds may increase over time as sea surface temperatures rise, the threat of repeated, intense bleaching events over the next several decades is a significant concern. If even the conservative predictions of global climate models are realized, these climate changes could result in the fundamental reorganization of the ecology of coral reefs.

The IPA team interview Peter Ridd. He explains that what's happening on the Great Barrier Reef with coral bleaching is a normal cycle. He tells his story of being censured at James Cook university, but admits the state of free speech at universities in Australia is non-existent — even after his win. They discuss how we might reform science with audits (universities are almost a lost cause). We'll probably never know how many scientists think similar thoughts to Peter Ridd. We know that they'll need a $250,000 legal fund if they say so...
