The phrase "average temperature increase compared to" is correct and usable in written English.
It can be used when discussing changes in temperature in relation to a specific reference point or baseline.
Example: "The average temperature increase compared to the last century has raised concerns among climate scientists."
Alternatives: "average temperature rise relative to" or "average temperature increase in comparison to".
Compared to autumn and winter, spring average temperature indicates lower but significant increase compared to the historical period.
Experts said the current agreement would hold the average temperature increase to perhaps just below 3 degrees Celsius.
... Policies that have been implemented, or are now being pursued, suggest that the long-term average temperature increase is more likely to be between 3.6 °C and 5.3 °C (compared with pre-industrial levels), with most of the increase occurring this century".
A safe threshold of <2°C increase in global average temperature compared to preindustrial temperatures has been proposed (2), as the effects of climate change then would be manageable.
None of these projects can go ahead if average temperature increases are to stay below 2 degrees Celsius.
Although the increase in thermal conductivity is a very important interest, there are also increases in the average temperature of nanofluids compared to that of base fluid and that because of the specific heat of nanofluids, which decreases compared to that of base fluid [12, 13].
Then they started to vary, and the average temperature increased by about 4.5 degrees Fahrenheit (but it was still very cold, averaging about 5 degrees above zero).
The impact of this "average temperature increase" on seasonal temperatures will be huge.
It also cross-compared their findings with average temperature increases from 1950 to 2014.
From north to south, average temperature increases and annual rainfall decreases.
Stanford scientists relied on historical data to predict that average temperature increases would continue, quickly evaporating average precipitation.
