Oaks are principally temperate zone trees or shrubs, estimating about 600 species globally. Oaks have remained on the non-glaciated territories of North America following the Cretaceous Period. According to the U.S. Forest Service , 50 oak species are represented in 2/3 of the eastern North American wood cover types and dominate 68% of hardwood forests (77 million hectares or 191 million acres).

Earth formed approximately 4.54 billion years ago and was mostly completed within 10–20 million years. In 4.4 billion years ago , our planet's first oceans formed. Water vapor was freed into the Earth's atmosphere by volcanism. It then cooled, dropped back down as precipitation, and created the planet's first oceans. Some water has additionally been delivered to Earth by asteroids and comets. 3.85 billion years ago , the first life emerged on the planet. Between 2.1 billion and 2.03 billion years ago , the increase of oxygen began rapidly, and the present situation was reached 1.5 billion years ago. Cyanobacteria make oxygen a product of photosynthesis. 700 million years ago , the first simple single-celled animals evolved.   530 million years ago , the first vertebrates in the ocean (fish) appeared on the planet. 400 million years ago , the first land plants developed. Oxygen in the atmosphere acted to form ozone, which created a layer. The ozone layer functioned as a pro...

Small multiple maps of global heating are the most popular way to visualize how average temperatures have risen over time. The maps show the anomaly of mean temperature for each calendar year, compared to the average over the standard reference period of 1961–1990. 110 years of Australian temperatures The colors range from dark blue (more than 3 °C below average), through blues and greens (below average), yellow and orange (above average), and on to brown (more than 3 °C above average) Source:  bom.gov.au 137 years of Germany temperatures 2018 was the hottest year since records started with an average annual temperature of 10.5 ° C. 1940 the coldest with 6.6 ° C.

The series of massive bushfires across Australia has been such an apocalyptic natural disaster (with more than five hundred million animals and plants killed), it can be difficult to perceive the whole scale of the natural disaster. According to the Telegraph, as of January 2, about 6 million hectares of land have been fired in Australia. For perspective, that's more land than the Netherlands and Denmark - and the smoke produced by the bushfires has stretched even more. Neil Kaye showed the absolute scale of the disaster by overlapping it on top of a map of Europe.
