Extreme weather disrupted the schooling of about 242 million children in 85 countries last year -- roughly one in seven students, the UN children's agency reported Thursday, deploring what it said was an "overlooked" aspect of the climate crisis.

The United Nations Children’s Emergency Fund, UNICEF, has urged stakeholders to intensify efforts to address the alarming statistic of 10.2 million primary school-aged children currently out of school in Nigeria.
