How do I download global Hansen Global Forest Change data from GEE?

Question

I have been trying to download 4 bands of the Hansen forest change data from GEE, and need the rasters to span the entire world. I have been using the following code to do so:

var myStringArrayGFW = ['treecover2000','loss','gain','lossyear'];
var dataset_name = "UMD/hansen/global_forest_change_2020_v1_8"; 
var dataset = ee.Image(dataset_name);
var myStringArray = myStringArrayGFW;
    
myStringArray.forEach(function(s) {
  var name = dataset_name.replace(new RegExp('/', 'gi'),'-');
  var data = dataset.select(s); 
  Export.image.toDrive({
    image: data,
    description: name+"-"+s, 
    scale:5000, //5x5km
    maxPixels: 1e13,
  });
  });  

Running this seems to work, as I can then save the files to my google drive, but the tifs I get are only a fraction of the size I need them to be (see picture below).

How would I go about fixing my code such that it downloads the entire rasters?

Specify a region spanning the whole world (easiest way is as a non-geodesic polygon that doesn't touch the poles); you're just getting whatever the code editor happens to be looking at when you start the Export.

Export.image.toDrive({
    image: data,
    region: ee.Geometry.Polygon([
        -180, 88, 
           0, 88, 
         180, 88, 
         180, -60, 
           0, -60,
        -180, -60], null, false]),
    ...
