Some people believe that the earth is closest to the sun in summer and further away in winter but actually thanks to something very big hitting the Earth at some point early in its history to knock it off kilter, instead of rotating with its axis perpendicular to its orbital plane, it is tilted so here we are, orbiting the Sun with the axis pointed in the same direction so different parts of the Earth get the suns rays as we travel through the year.
At this time of the year the top half of the planet is tilting away from the sun meaning winter and the bottom half is tilted towards it giving summer.
To prove it you only have to see the weather differential in America in the Northern Hemisphere and Australia in the Southern.
Parts of the US are expecting what could be the coldest night in the country's history, with temperatures expected to drop as low as -35°C while in Australia the emergency services are warning people to stay indoors as a dangerous heatwave batters the country, with temperatures exceeding 45°C melting the roads.
The highest ever temperature recorded on Earth is 56.7 °C in Death Valley, California while the lowest is −89.2 °C at the Vostok Station in Antarctica.
As the Globe continues to warm and Mother Nature takes the weather that is there and ramps it up dangerously giving killer heat waves, strengthened hurricanes, heavier rainfalls and massive snow dumps, extreme weather will become the norm so it is something that we will have to get used to.
