Oct 1, 2019 · While global warming focuses on the rising average temperature of the planet, climate change usually refers to the shifts in things like precipitation, wind patterns, and temperatures over a given period. Measured changes in climate could last a few years, decades, or even millions of years.
Causes and Effects of Climate Change. Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global...
4 days ago · This article provides an overview of the scientific background related to the subject of global warming. It considers the causes of rising near-surface air temperatures, the influencing factors, the process of climate research and forecasting, and the possible ecological and social impacts of rising temperatures.

… Climate Change. The Causes of Climate Change. Human activities are driving the global warming trend observed since the mid-20th century. En español. Takeaways. The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space.
Vital Signs of the Planet: Global Climate Change and Global Warming. What is the “greenhouse effect”? What is causing it? Are humans to blame? What does solar irradiance have to do with it? Answers here.
Climate change has caused increased heat, drought, and insect outbreaks. In turn, these changes have made wildfires more numerous and severe. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities.
Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
