# Maths for Planet Earth: Climate Based Questions for students and teachers

A team of students and academics at the Environmental Change Institute, School of Geography and the Environment, and Department of Physics, University of Oxford, developed the Maths for Planet Earth questions. They work on climate and energy issues and are passionate about inspiring young people to join the fight against climate change.

The world needs brainy mathematicians to help tackle climate change.

The aim of these questions is to integrate climate change into the school curriculum beyond the usual suspects of geography and environmental science.

These questions closely follow example problems from GCSE and A level past exams and were developed using existing exam questions. The maths skills tested in the question remained unchanged, but the context of the question was adapted to a climate change theme.

##### Finding the Total Carbon Dioxide Emissions from 1850
The graph below shows how the rate of CO2 emissions varies from 1800 to 2017. This curve can be approximated as (E = 1.5e^{0.02t})
A Level
##### A Regrowing Reef
a) Use the substitution (u = 4 – sqrt{s}) to show that [int_{}^{}frac{text{dh}}{4 – sqrt{s}} = – 8lnleft| 4 – sqrt{s} right| – 2sqrt{s}

##### 50 Years to Net-Zero
A country wishes to achieve net-zero CO2 emissions in 50 years.  At the start of the program their emissions are 800MtCO2 year-1.  They decide
