From the page you show you can probably click on Profile and a link to warnings will be just below and to the right of the avatar picture there.
If that doesn't work then:
Go to one of your posts.
Right Click on your user name beneath your avatar picture.
A pop up window will open.
Click on the top option, "open link in a new tab".
A new tab will open in your browser.
Go to that tab and just below your avatar picture there you should see a link to your warnings.
