fusion is called thermonuclear for a good reason: it needs a lot of heat to get started.
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
For nuclear fusion.
The high temperature of the Sun's core is necessary for nuclear fusion to occur. Fusion reactions at this temperature produce the tremendous amount of energy that allows the Sun to shine and sustain life on Earth.
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
Stars generate light through nuclear fusion in their cores. This process involves converting hydrogen into helium, which releases energy in the form of light and heat. The intense pressure and temperature within a star's core allows this fusion process to occur.
How can temperature either help fusion to occur or prevent fusion from occurring?
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
Fusion reactions occur in the cores of stars, including our Sun, where temperatures are extremely high, on the order of millions of degrees Celsius. No other location in the solar system has temperatures high enough to sustain fusion reactions.
Not enough pressure or temperature.
Because the conditions of temperature and pressure that occur in stars do not occur on earth
Nuclear fusion reactions require extremely high temperatures, typically in the range of 100 million to 150 million degrees Celsius, in order to overcome the electrostatic repulsion between positively charged atomic nuclei and allow them to fuse together. This extreme heat is needed to create the conditions necessary for the fusion process to occur and release energy.
The minimum temperature is about 10,000,000 degrees Celsius.

The cause is the very high temperature.
In areas of high temperature and high pressure
One significant difficulty in using fusion as an energy source is the challenge of containing and controlling the extremely high temperatures and pressures required for the fusion reaction to occur.
Nuclear fusion occurs in the solar core.
