Don't worry the earth has always had changeable weather, it gives us something to talk about, think how boring it would be if it was so predictable.
The Earth cannot tilt a little bit without people noticing. Geodesists and astronomers know precisely where the Earth it pointing--their jobs depend on that. It's also very difficult to make the Earth tilt--it's essentially the biggest gyroscope you've ever seen.
I heard, well my science teacher told me that every six months that the continents drift like half a millimeter away from eachother, that didn't really answer your question, but yes, the earth is going through changes day by day!
maybe not sure. makes sense though
i had a weird theory the other day. i noticed the last two years has been very warm. what if something (i dont know what) caused the earth to tilt a little bit. Wouldnt that change the temperature? Is this even possible? do you think it could of happened?
