As the Earth spins each day, the new heat swirls with it, (3) ____ up moisture over the oceans, rising here, settling there. It’s changing the rhythms of climate that all living things have come to rely upon.

What will we do to slow this warming? How will we cope (4) ____ the changes we’ve already set into (5) ____? While we struggle to figure it all out, the face of the Earth as we know it-coasts, forests, farms and snow-capped mountains-hangs in the balance.

Global warming refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which (1) __________ carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, (2) __________ rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

While consensus among nearly all scientists, scientific organizations, and governments is (3)__________ climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence. Climate change deniers often claim that recent changes (4) __________ to human activity can be seen as part of the natural variations in Earth’s climate and temperature, and that it is difficult or impossible to establish a direct connection between climate change and any single weather event, such as a hurricane. While the latter is generally true, decades of data and analysis support the reality of climate change and the human factor in this process. In any case, economists agree that acting to reduce fossil fuel emissions would be far less expensive than (5) __________ with the consequences of not doing so
