Only one mammal on tiny island supposedly wiped out by climate that has always changed

In a nutshell — this poor little rat lived on a outcrop in the ocean near Papua New Guinea that was 300m long. It’s now gone, and some people blame “climate change”. A thousand tide gauges show the oceans are rising at 1mm a year. We also know the world was much hotter 7,000 years ago, and sea levels rose 125m in the 7,000 years before that. Somehow the rat survived that massive natural shift. Now though, its precarious existence was destroyed by your air conditioners, cars and because you ate too much meat. Modern witchcraft.

Revealed: first mammal species wiped out by human-induced climate change

Human-caused climate change appears to have driven the Great Barrier Reef’s only endemic mammal species into the history books, with the Bramble Cay melomys, a small rodent that lives on a tiny island in the eastern Torres Strait, being completely wiped-out from its only known location.

It is also the first recorded extinction of a mammal anywhere in the world thought to be primarily due to human-caused climate change.

So despite the non-stop fear campaigns about polar bears, possums, wallabys, bats, hares, pikas, this is it — the sole actual example of an extinction of a mammal living in the most high risk situation there is that is “thought” to be due to man-made climate change? So zero other extinctions. More likely zero extinctions “due to man-made weather” full stop.

The rodent, also called the mosaic-tailed rat, was only known to live on Bramble Cay a small coral cay, just 340m long and 150m wide off the north coast of Queensland, Australia, which sits at most 3m above sea level.

And here’s the graph of sea levels recorded in the best tide gauges at Papua New Guinea and the Solomon Islands according to the Australian Bureau of Meteorology. Here is the mammal-killer sea-level rise. Spot the effect of increasing CO2?

When this graph begins in 1994, CO2 levels were at 356ppm. Now they are 50ppm higher. How much difference did 50 ppm make?

Note that the rate per year recorded in the same document is 4 – 5mm a year. The start date of 1994 has a big effect — Mt Pinatubo probably reduced sea-levels around the world, (see also this page) and some of the rise in the graph above is more about recovery from that natural low.
