Australian Heatwave? Not So Unusual After All | NOT A LOT OF PEOPLE KNOW THAT
In none of the examples is the January temperature a record, or even close to being so, and in most cases higher temperatures were recorded 50 years or more ago.

But don’t take my word for it. NSW was probably the worst affected state, yet, according to the Australian Bureau of Meteorology (BOM), it was only the 5th warmest January since 1910, and all the others occurred prior to 1940. In other words, a once in 20 years event.
(Mis)Understanding Sea-Level Rise (SLR) and Climate Impacts – Significant Figures by Peter Gleick
One of the most important and threatening risks of climate change is sea-level rise (SLR). The mechanisms are well understood, and the direction of changes in sea-level is highly certain – it is rising and the rate of rise will accelerate. There remain plenty of uncertainties (i.e., a range of possible outcomes) about the timing and rate of rise that have to do with how fast we continue to put greenhouse gases in the atmosphere, the responses of (especially) ice sheets in Greenland and Antarctica, and the sensitivity of the climate.

Even little changes can have big consequences. As we saw with Superstorm Sandy, where extremely severe weather was combined with a very high tide, on top of sea levels that have risen six to nine inches over the past century, even a little bit of sea-level rise around the world has the potential to cause hundreds of billions of dollars of damages and the displacement of millions of people.
New survey shows ‘climate change’ still not catching on as a concern | Watts Up With That?
The surveys showed that when asked to rank priority worries, people were five times more likely to point to the economy over the environment.
