All too often American politicians, correction Republican politicians (I never know what country the Republicans identify with, USA, Russia, Ukraine?) present the idea, the climate is not or is responsible for their particular point of view. That is an extremist excuse for not addressing the climate crisis.

In this reporting from the BBC, they responsibly assigned the climate 30 % responsible for the inferno that was Australia.

It is not all or nothing. It never has been. The TRENDS for decades have pointed to a hotter troposphere. The weather manifestations are those normally seen in climate, however, the extreme events that are taking place are catastrophic. The weather due to climate is not always catastrophic.

As an example:

Traditional weather in the USA only three decades ago saw tornadoes in the USA from March through June. Then the tornado season would end only to realize the Atlantic hurricane season began from June 1st to November 30, while the Pacific hurricane season began May 15th and end November 30th.

All that SEASONAL weather has changed. Tornadoes are no longer just those few months but occur year round. We now have seen a very strong in March that killed Americans. (click here) It was a tornado, yes. But, it was not a normal tornado during a normal tornado season. Not only this as an example, but, the normal tornado season now spawns tornado outbreaks of multiple vortexes. That was once a rare occurrence, now it happens frequently every tornado season.

The climate crisis has changed Earth's climate and it is showing up in catastrophic weather. Australia even lost it's beautiful Great Barrier Reef because of ocean temperatures. It is long past time to take this seriously.

Global warming boosted the risk of the hot, dry weather (click here) that's likely to cause bushfires by at least 30%, they say.

But the study suggests the figure is likely to be much greater.

It says that if global temperatures rise by 2C, as seems likely, such conditions would occur at least four times more often.

The analysis has been carried out by the World Weather Attribution consortium....

Rural Fire Service crews engage in property protection during wildfires along the Old Hume Highway near the town of Tahmoor, Australia, outside Sydney, Dec. 19, 2019. Wildfires have been burning since August and have destroyed an area comparable to the combined region of the Netherlands and Belgium.

As extreme wildfires (click here) burn across large swaths of Australia, scientists say we're witnessing how global warming can push forest ecosystems past a point of no return.

Some of those forests won't recover in today's warmer climate, scientists say. They expect the same in other regions scarred by flames in recent years; in semi-arid areas like parts of the American West, the Mediterranean Basin and Australia, some post-fire forest landscapes will shift to brush or grassland.

More than 17 million acres have burned in Australia over the last three months amid record heat that has dried vegetation and pulled moisture from the land. Hundreds of millions of animals, including a large number of koalas, are believed to have perished in the infernos. The survivors will face drastically changed habitats. Water flows and vegetation will change, and carbon emissions will rise as burning trees release carbon and fewer living trees are left to pull CO2 out of the air and store it.

In many ways, it's the definition of a tipping point, as ecosystems transform from one type into another....
