The accuracy until 1979 is limited, but the best guess we have is that the planet in 1900 was 0.1 degree below normal and we are currently 0.4 degrees above normal. The late 1800's and early 1900's were low temperature periods of the last mini ice age.
From 1983 to 2012, it was maybe warmer, I suppose, which lasted for 30 years over the last century.

Yes, the average temperature of the Earth has increased over the last five years. This trend aligns with long-term patterns of global warming attributed to human activities, particularly the burning of fossil fuels and deforestation. Data from climate monitoring agencies consistently show rising temperatures, with recent years often ranking among the warmest on record.
At the upper edge of the cloud cover, the temperature is thought to be -145 degrees C. On Jupiter the temperature increases because of atmospheric pressure, so as you descend temperature increases. Not far into the atmosphere the pressure is about ten times what it is here on Earth and the temperature is thought to be about 20 degrees C or average room temperature for Earth. Descend further and the temperature is thought to be over 9,700 C.s
Known as the Miklankovitch cycles, they operate on different timescales. Eccentricity relates to the fact that the earth's orbit changes to being more or less elliptical about every 100,000 years. Obliquity relates to the fact that the axis if the earth varies in inclination over a cycle of 41,000 years. Precession relates to the fact that the earth wobbles slightly in its axis over a period of 23,000 years. All these cycles vary so that sometimes they add to each other, and sometimes they are working against each other, and this affects the amount of sunlight reaching the earth. This promotes regular changes in the earth's temperature, over which we have no control.
The earth's average global temperature has risen 0.75 degrees Celsius (approx 1.3oF) in the last hundred years.A:The earth has warmed by 0.9 degrees Fahrenheit in the past 100 years. A:0.82 degrees Celsius.Approximately 0.6 degree Celsius.
Global warming is a rapid change. The earth's temperature has risen very fast in the past 50 years, compared to the very gradual rise over the past 12,000 years, the time of the last Ice Age.
The National Academy of Sciences reports that the Earth's temperature has risen by about 1.4 degrees Fahrenheit in the past century. This increase is largely attributed to human activities such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere and contribute to global warming.

The average temperature of Earth is about 15°C (59°F). This is based on global measurements taken over many years.
Global warming is the name given to the recent (over 200 years) gradual increase in the temperature of Earth's atmosphere.
Because we have evolved over millions of years to suit this environment
Supposedly because transportation costs have risen so sharply.
Salt is not formed in the sea. The salt existed before the water was there. As the oceans have risen and fallen and risen again over millions of years, they dissolved the salts on the ground and in rocks.
From 1983 to 2012, it was maybe warmer, I suppose, which lasted for 30 years over the last century.
Less trees, more people, more pollution.
