Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. A warming Earth disturbs weather, people, animals and much more.


Here, we look at three critical aspects of an increasingly warmer planet.

  1. More heat alters ice, climate and oceans

Change in temperature affects the Earth in following ways:

  • the frozen water on Earth is melting
  • Weather is getting more extreme. Heat waves are more frequent worldwide.
  • The oceans are getting hotter and are expanding because of which they are becoming more acidic. They are getting hotter because they absorb 90 percent of the extra heat in the climate.
  1. 2. Human life and prosperity suffer

Our health, economy, livelihoods, infrastructure and much more suffers

●       Climate change is a significant threat to is struggling to keep up with shifting weather patterns and increasingly unpredictable water supplies.

●       Warmer, polluted air affects our health.

●       Hot weather, flooding and other extremities of weather events damage infrastructure, put heavy burdens on electrical supplies and disrupt transportation

3. Natural habitats become hostile

Here are three well-documented examples of changes to the natural world:

  • The ice Arctic animals need is vanishingAs sea ice disappears, ice-dependent mammals such as walruses and polar bears struggle to survive. 
  • Coral and shellfish suffer the most. Coral reefs are very sensitive to small changes in ocean temperatures.
  • Forests are more prone to deadly infestations.

Effects of Climate Change

The climate change will continue through this century and beyond the next few decades and will have a long-lasting effect on the planet. It depends primarily on the amount of heat-trapping gases emitted globally, and how sensitive the Earth’s climate is to those emissions. Temperatures will continue to rise and will not be, uniform or smooth across the country or over time. The frost-free season will lengthen. The Arctic Ocean is expected to become substantially ice-free in summer before mid-century.

Future climate projections over the Earth that the recent trend towards increased heavy rainfall will continue. This trend is projected to appear even in regions where total precipitation is expected to decrease, such as the Southwest. Global sea level has been increased by about 8 inches since reliable record. Sea level will rise 1-4 feet by 2100. It is the result of added water from melting land ice and the expansion of seawater as it warms.

Droughts in the Southwest and heat waves are becoming more intense and cold waves less intense everywhere. Summer temperatures are expected to continue rising, and a reduction of soil moisture is anticipated for most of the western and central U.S. in summer. The intensity, frequency, and duration of North Atlantic hurricanes, as well as the frequency of the most vigorous cyclones, have all increased since the early 1980s.
