It is 0% true. Pure propaganda.
This winter is going to continue to be cold. The summer will be cool. The following winters are going to be brutally cold. Why? That big burning ball of thermonuclear fire in the sky is entering/has entered a dormant period, as in less sunspots and lower magnetic activity. That leads to more clouds and cooler weather. In fact, we may be entering a mini ice age.
So again, the claim is pure propaganda.
The real scientists in NASA have also discovered that UV light emission from the sun varies significantly over the solar cycle. UV light affects the ozone hole and the heat energy in the upper outer atmosphere. For NASA to now admit the truth, that they have been wrong about the sun since the ozone hole scare, would destroy their credibility. So they will not help to warn and prepare civilization for the coming ice age. NASA will be irrelavent to the future. They went down the rabbit hole of lies and there is no coming out.
