This is only my second tab, but I'm wicked confident that these are right!
These chords sound more like the recorded song when you half strum half pluck the verse.
On my ukulele,I strum down with my thumb on the top 3 strings and then use my index
finger on the bottom string to strum up.( If this doesn't make any sense, I'm very 
sorry) And the strumming pattern is Down down up up down up.

[Intro] G C G C

[Verse 1]
 G       C                    G    C
Emma, I feel I owe you this letter
 G       C                          G    C
Do ya, know I'm crazy about your weather
   Am                         C
'Cause it's raining in your world
Am                        C                  G
And I'm the only one you know with a good umbrella
  C
Ooooo

[G C G C]

[Verse 2]
       G              C                             G   C
Sweet Emma, do you remember when we used to fall asleep
  G        C                              G
Under the tent I built from a Star Wars sheet
          Am             C
We were barely pushing twelve
         Am                   C       G
Riding bikes we both raised hell, Together
  C
Ooooo

[Chorus 1]
        Am
Every time your heart was cut in two
           C
I'd make paper flowers all for you
         Am               C
I would rip away those clouds
                G
Here comes the sun
          Am
I would hold your hand take you far away
          C
Nothing make believe in the words I say
         Am              C                        G  C
I will always fix your soul when you're falling down

[G C G C]

[Verse 3]
        G            C                    G    C
Please Emma, as you cry for him upon my pillow
   G             C                            G
Remember, I will be right here your weeping willow
     C
My bird
             Am                  C
All through high school not my choice
         Am                      C
Just a friend while you chased boys
       G
You forgot me
    C
Ooooo

[Chorus 2]
        Am
Every time your heart was cut in two
           C
I'd make paper flowers all for you
         Am                C
I would rip those clouds away
                G
Here comes the sun
         Am
I would make you smile he would make you cry
           C
He's not good enough, please don't roll your eyes
         Am             C                 G   C
Little bird I know you know, I love you still

[Outro] G C G C G
