TEN CLEAR INDICATORS OUR CLIMATE IS CHANGING
TEN CLEAR INDICATORS OUR CLIMATE IS CHANGING

The Climate Reality Project Organization

1. AIR TEMPERATURES OVER LAND ARE INCREASING.

It´s clear that weather stations on land show average air temperatures are rising, and as a result, the frequency and severity of droughts and heat waves are increasing. Intense droughts can lead to destructive wildfires, failed crops, and low water supplies, many of which are deeply affecting southern areas of the United States and other parts of the world.

2. AIR TEMPERATURES OVER OCEANS ARE INCREASING.

Roughly 70 percent of the world is covered by oceans, so you can understand how hotter air over them could make a vast difference in the climate system.
Oceans evaporate more water as the air right near the surface gets warmer. The result: More floods, more hurricanes, and more extreme precipitation events.

3. ARCTIC SEA ICE IS DECREASING.

Satellite images from space show that the area covered by sea ice in the Arctic is shrinking, and it´s continued a downward trend for the past 30 years. The Arctic ice cap grows each winter when there´s less sunlight, and shrinks each summer when days are longer, reaching its lowest point of the year in September.

Some research suggests that the Arctic could lose almost all of its summer ice cover by 2100, but others believe that it could melt completely much sooner than that – in just a few decades.

4. GLACIERS ARE MELTING.

The disappearance of glaciers is one of the clearest signs of climate change. People who rely on melting glacier water are facing shortages, and in many regions, the situation is only getting worse.

In a world unaffected by climate change, glacier mass stays balanced, meaning the ice that evaporates in the summer is fully replaced by snowfall in the winter. However, when more ice melts than is replaced, the glacier loses mass. And the people who depend on melting ice for water to support their farming and living needs are deeply affected.

5. SEA LEVELS ARE RISING.

Sea levels have been rising for the past century. And the pace is only increasing in recent years as glaciers melt faster and water temperatures increase, causing oceans to expand. Let´s not forget that eight of the 10 largest cities in the world are near a coast.

Consider how many millions of people are at risk as sea levels rise, storms intensify, and more extreme flooding occurs. Additionally, marine life is threatened as salt water intrudes into fresh water aquifers, many of which support human communities and natural ecosystems.
