The science of climate change is complex but climate reacts to whatever forces it to change; humans are now the dominant force. Climate change simply refers to the lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years.
Climate change is caused by factors that include oceanic processes; variations in solar radiation, plate tectonics and volcanic eruptions, and human-induced alterations of the natural world. These effects are currently causing global warming, and “climate change” is often used to describe human-specific impacts on the earth.
FACTS ABOUT CLIMATE CHANGE
- Average global temperatures increased by about 1 degree Celsius over the 20th century.
- The United States contains only 5 percent of the world’s population, but contributes 22 percent of the world’s carbon emissions.
- The Golden Toad is thought to be the first species to go extinct because of climate change.
- Climate change is linked to stronger hurricanes, more drought and increased coral deaths from bleaching.
- Climate change is linked to an increase in disease-carrying pests that lead to the increased spread of diseases such as dengue fever, malaria, lyme disease and West Nile virus.

CLIMATE CHANGE IN NEPAL
The climate in Nepal varies from the tropical to the arctic within the 200 km span from south to north. Much of Nepal falls within the monsoon region, with regional climate variations largely being a function
of elevation. National mean temperatures hover around 15 °C, and increase from north to south with the
exception of mountain valleys. Average rainfall is 1,500 mm, with rainfall increasing from west to east. The northwest corner has the least rainfall. Rainfall also varies by altitude; areas over 3,000 m experience a lot of drizzle, while heavy downpours are common below 2,000 m (USCSP 1997). Although annual rainfall is abundant, its distribution is of great concern: flooding is frequent in the monsoon season during the summer, while droughts are not uncommon in certain regions in other parts of the year.
We can all reduce climate change by doing our part to decrease the emission of heat-trapping gases to the atmosphere.
Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.
Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.
