The average rainfall in Australia is also potentially skewed towards a higher value because of freak flooding/heavy rain events in the north of the country in recent times. That doesn't discount the fact that it's been mostly drier down here in the south, save 2010/11. here's an annual temperature and rainfall plot for just New South Wales. Kinda tempted to make a similar plot for Massachusetts, precipitation must be nowhere as variable. |

just used NOAA's plots rather than trying to make those 2-D dot plots myself. Clear warming trend  looks like it has gotten wetter but much less variable than NSW  |

This hasn't anything to do with climate change, but the population of Australia is 5 times larger than it was in 1900, and per capita people use much more water now than then, so the water consumption has gone up dramatically. Therefore "drying out" might not be an exaggeration.

Sir David Attenborough warns of climate 'crisis moment'
"The moment of crisis has come" in efforts to tackle climate change, Sir David Attenborough has warned.
According to the renowned naturalist and broadcaster, "we have been putting things off for year after year".
"As I speak, south east Australia is on fire. Why? Because the temperatures of the Earth are increasing," he said.
Sir David's comments came in a BBC News interview to launch a year of special coverage on the subject of climate change.
Scientists say climate change is one of several factors behind the Australian fires; others include how forests are managed and natural patterns in the weather.
Sir David told me it was "palpable nonsense" for some politicians and commentators to suggest that the Australian fires were nothing to do with the world becoming warmer.
"We know perfectly well," he said, that human activity is behind the heating of the planet.

I thought TV show hosts' opinions went in the climate activism thread.

A graph of how much climate models have been overestimating the warming:
And despite the warm winter in Europe, snow cover in the northern hemisphere is more than a standard deviation above average:

Where is the snow above average then? Definetly not Europe or North America |

TBH, Northern Finland and Sweden have snow depths way above average.

My apologies, thought it was just cover - not mass. North America is similar but father north in Canada not the US. Sad when northern New England and NY/PA can barely hold a snowpack |

Those graphs show significant warming since the 1800s though which your source also mentions.

Well your last graph shows the warmest since the 1400s and all of them are the warmest since the 1800s. And the trend was cooling so it is significant that the trend the last 200 years has switched to warming. And global warming doesnโt mean the warmest itโs ever been, just that thereโs a current warming trend which is largely caused by people. |

TSI (Total Solar Irradiance) is the more likely culprit for post-Little Ice Age warming:   CO2, on the other hand, shows less-than-sound causation (Temperature in red; Atmospheric CO2 in green):  |
