[Tex/LaTex] Left-aligning all text in itemized list (beamer)

beamerindentationitemizelists

I'm trying to make an itemized list in beamer (using the beamerposter package). By default, the text of first-level bullet points is left-aligned at the same point as non-list text, and the bullet actually comes before that. I want the bullet point to be aligned with or even further right from the non-itemized text, so I added a line to indent it (\setlength etc.):

\begin{block}{Evaluation}
    Compare seasonality estimated by our method with that in:
    \begin{itemize}
        \setlength{\itemindent}{1.5em}
        \item ``Agricultural" grid cells ($p_a > 0.8$) 
        \item ``Non-agricultural" grid cells ($p_a < 0.2$)
        \item 80\% threshold based on the land cover classification scheme for cropland discussed by \citep{Hansen:2000wm}.
    \end{itemize}
\end{block}

Here is a picture of the result:

Unfortunately, this solves one problem and creates another. The third item has to have a line break, and the text on the second line is not left-aligned with the rest of the itemized list text. How do I make it align?

Try influencing the left margin instead of the item indent to get the alignment right. This can be done by changing the length \leftmargini before \begin{itemize}:

\documentclass{beamer}
\usepackage{beamerposter}
\begin{document}
\begin{frame}
\begin{block}{Evaluation}
    Compare seasonality estimated by our method with that in:
    \setlength{\leftmargini}{2.5em}
    \begin{itemize}
        \item ``Agricultural" grid cells ($p_a > 0.8$) 
        \item ``Non-agricultural" grid cells ($p_a < 0.2$)
        \item 80\% threshold based on the land cover classification scheme for cropland discussed by [10].
    \end{itemize}
\end{block}
\end{frame}
\end{document}
