Historians agree that when colonists settled at Jamestown, it was one of the coldest periods in the last 1000 years. Drought was also a problem in North America during the Little Ice Age, and the settlers arrived in Roanoke during the largest drought of the past 800 years. Tree ring studies by the University of Arkansas discovered that many colonists arrived at the beginning of a seven-year drought. The droughts also decreased the Native American populations and led to conflict because of food scarcity. English colonists at Roanoke forced Native Americans of Ossomocomuck to share their depleted supplies with them. That led to warfare between the two groups, and Native American towns were destroyed. That cycle would repeat itself many times at Jamestown. The combination of fighting and cold weather also led to the spread of diseases. The colder weather helped the parasites brought by Europeans in mosquitoes to develop faster. That in turn led to many malaria deaths among Native Americans.
