The most pressing crisis facing the planet is the warming of the earth's climate. Responding to this crisis influences the work of nearly everyone working with the environment. 

If you are interested in subjects such as geography, geology, mathematics, statistics, marine science, ecology, environmental science, computer science, law, physics or earth science there are many career opportunities in multiple disciplines.

Government agencies promote and enforce climate protection policies, getting individuals and companies to release less carbon into the atmosphere. Habitats need to be protected from the effects of a changing climate, such as heatwaves and harsher winters.

Meteorologists study the atmosphere and how processes in the atmosphere determine Earth's weather and climate. Meteorology is a very practical science because everyone is concerned about the weather. How climate changes over time in response to the actions of people is a topic of urgent worldwide concern. 

Oceanographers work to develop the ocean as a resource and protect it from human impact. The oceans also have a major influence on the weather and changes in the oceans can drive or moderate climate change The goal is to utilise the oceans while minimizing the effects of our actions.

In the earth sciences, the work of climatologists is becoming more pressing, as they study the developing changes in the earth's climate. Environmental Scientists play a key role too, as they develop our understanding of how the environment is changing due to the warming climate and how we should react to it.
