Climate is an increasing riskfactor for migration in which of the following regions

1. NA asia and europe
2. Europe SA and the Us
3. Sub saharan africa Europe and NA
4. S+E asian SS africa and Latin american

The regions where climate is an increasing risk factor for migration are:

3. Sub-Saharan Africa, Europe, and North America

To determine which region climate is an increasing risk factor for migration, we need to assess the impact of climate change on migration patterns in each of the listed regions. Let's break down the options:

1. NA (North America), Asia, and Europe: While all three regions are affected by climate change, in this case, it is not specific enough to conclude whether climate change is an increasing risk factor for migration in these regions.

2. Europe, SA (South America), and the US (United States): Again, all three regions are impacted by climate change, but it doesn't specify whether climate change is a primary risk factor for migration in these regions.

3. Sub-Saharan Africa, Europe, and NA (North America): Sub-Saharan Africa is known to be highly vulnerable to climate change, particularly due to its reliance on agriculture and susceptibility to extreme weather events. Europe and North America are also affected by climate change, but to a lesser extent than Sub-Saharan Africa. Climate change can potentially exacerbate existing migration patterns in this region, making it an increasing risk factor for migration.

4. S+E (Southeast) Asia, Sub-Saharan Africa, and Latin America: Southeast Asia, particularly countries like Bangladesh and the Philippines, is highly vulnerable to the impacts of climate change, including rising sea levels and increased frequency of extreme weather events. Sub-Saharan Africa has been mentioned before as being highly affected by climate change. While Latin America is also affected by climate change, it is not commonly identified as a hotspot for climate-induced migration.

Considering the information provided, option 3, Sub-Saharan Africa, Europe, and North America, is the most plausible answer as climate change poses an increasing risk factor for migration in these regions, particularly in Sub-Saharan Africa.
