Climate research

The text below from May 2006 describes research activities in the European research network ACCENT. Fill in either “is / are going to” or “will”.

Our climate is changing. What will a future world look like?

Scientists in the ACCENT network __________ study the composition of the air to learn about changes in chemistry and physics of the atmosphere. Some examples:

The world’s population __________  continue to grow over the coming decades and people __________  most likely use more energy. We do not know exactly how the economy, technologies and society __________  develop. Some research groups in ACCENT __________  develop scenarios to test the climate response for each set of assumptions. Because of uncertainties in the assumptions climate scientists __________  never be able to predict what exactly the climate __________  be like at the end of the century.

Air pollution is still an important problem. Politicians in many countries have said that they __________  take measures to reduce emissions. This is important because pollution not only affects their own country but spreads around the world. In late autumn 2006, scientists from ACCENT __________  meet to discuss the present knowledge about organic compounds coming not only from industrial and traffic emissions, but also from natural sources.

Ozone in the air surrounding us is not healthy. Furthermore, ozone is a greenhouse gas making our planet warmer. Politicians __________  take further measures in order to reduce emissions in large cities. We hope that ozone smog events __________  become less frequent in the future. Background ozone far away from cities has increased. ACCENT has decided that research groups __________  look at whether levels of background ozone will increase further in the future.
