As I unerstand now tokens are not available for sale. The botton to buy tokens on the website is not active.
But airdrop is a good reason to attract the attention of the community to the project before the token sale.
I checked their webite there is such information on it
CLIME Pre-Sale is coming soon, stay tuned to our social media and don't miss the chance to participate in our airdrop promotion.
That is why the buttun CLIME is not active.
