Changes in temperature and ice over the last 450,000 years (Antarctic data).Life appeared on Earth between 3.8 and 3.5 billion years ago, in the form of the first cells. It was the first living organisms capable of recovering carbon from atmospheric CO2 dissolved in water and progressively enriching the atmosphere with oxygen (photosynthesis) that set in motion the dynamic cycle of water and ...
Spring and autumn have, on average, mild days and cool nights but are changing and unstable. Surprisingly warm or cool weather occurs frequently in both seasons. [4] In winter, sunshine is scarce; days are cool, nights cold but generally above freezing with low temperatures around 3 °C (37 °F). [5]
This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.

This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess).
In the coldest month – January, typically the temperature ranges from 15 to 20 °C (59 to 68 °F) during the day and 6 to 10 °C (43 to 50 °F) at night. In the warmest month – August, the typical temperature ranges from 28 to 32 °C (82 to 90 °F) during the day and about 22 to 23 °C (72 to 73 °F) at night.
