The study predicts that polar climates will shrink whereas arid regions will expand. Large swathes of Earth will switch from cool summers to hotter summers. And at low latitudes, mountainous regions will shift climate zones earlier than nearby low-altitude areas.
How will climate zones be affected over the next century?
Across the globe, in response to increases in heat-trapping gases such as carbon dioxide (CO2) in the atmosphere, temperature and precipitation patterns are changing. The rate of climatic change in the next century is expected to be significantly higher than it has been in the past.
How is climate change affecting climate zones?
Higher temperatures are also expected to cause a shift in the geographical distribution of climate zones. These changes will impact the distribution and abundance of many plant and animal species, which are already under pressure from habitat loss and pollution.
What areas will be affected the most by climate change?

What is causing climate zones to change?
These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.
Will it be hotter or colder in the future?
Climate models predict that Earth’s global average temperature will rise and additional 4° C (7.2° F) during the 21st Century if greenhouse gas levels continue to rise. … According to model projections, if we reduce greenhouse gas emissions, there will be about a degree of warming over this century (the purple line).
Are the growing zones changing?
Plant Hardiness Zones are moving north in the U.S. at 13 miles per decade. Hardiness zones in the U.S., which track average low temperatures in winter, have all shifted northward by half a zone warmer since 1990. Source: United States Department of Agriculture.
What regions are affected by climate change?
The Arctic, Africa, small islands and Asian megadeltas and Australia are regions that are likely to be especially affected by future climate change. Africa is one of the most vulnerable continents to climate variability and change because of multiple existing stresses and low adaptive capacity.
How the climate of a region is affected by altitude?
Temperature decreases with increasing height above sea level. This makes the higher areas to have lower temperatures than the lower areas. A rise in altitude causes a fall in temperature and a cooling effect which causes condensation.
How might changing climate zones affect the plants and animals that live in them?
Climate change also alters the life cycles of plants and animals. For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too.
How will climate change affect different parts of the world?
Changes in Earth’s climate have different effects in different areas of the world. Some places will warm much more than others, some regions will receive more rainfall, while others are exposed to more frequent droughts. Regional changes in temperature and precipitation are having impacts on people and ecosystems.
What will climate change do?
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
How does climate change affect cities?
Rising global temperatures causes sea levels to rise, increases the number of extreme weather events such as floods, droughts and storms, and increases the spread of tropical diseases. All these have costly impacts on cities’ basic services, infrastructure, housing, human livelihoods and health.
