A recent Nature study expecting more severe hurricanes from global warming still found that damages would halve from 0.04 per cent to 0.02 per cent of global GDP, because the increased ferocity would be more than made up by increased prosperity and resilience.
(2001) projected losses in world GDP for a medium increase in global mean temperature (above 2–3 °C relative to the 1990 temperature level), with increasing losses for greater temperature increases.

Multiple lines of evidence indicate Greenland's ice loss is accelerating and will contribute sea level rise in the order of metres over the next few centuries.
The contribution of the Greenland ice sheet on sea level over the next couple of centuries can be very high due to a self-reinforcing cycle (a so-called positive feedback).

It seems scientists have noticed recently that quite a few planets in our solar system seem to be heating up a bit, including Pluto."
The presence of methane, a powerful greenhouse gas, in Pluto's atmosphere creates a temperature inversion, with the average temperature of its atmosphere tens of degrees warmer than its surface, though observations by New Horizons have revealed Pluto's upper atmosphere to be far colder than expected (70 K, as opposed to about 100 K).

The bushfires in Australia were caused by arsonists and a series of lightning strikes, not 'climate change'.
"Climate change is one factor affecting how fires in Australia burn, regardless of whether arsonists or lightning started them".
