Climate change is a global problem whose ef ects are being felt in every corner of the world; its stakeholders include every person in our Region and beyond. To meet this enormous challenge will require action by governments, UN and other development agencies, the corporate sector, communities and individuals.
Climate change (sometimes called global warming) is the process of our planet heating up. Our planet has already warmed by an average of 1°C in the last 100 years and if things don’t change, it could increase by a lot more than that.
Climate is what we do expect. Weather is what we get. Is greenhouse effect useful or not? How do we know that the world is warming? The increase in global temperature is following the atmospheric carbon dioxide concentration.
Climate change is a real and urgent challenge that is already affecting people and the environment worldwide. Significant changes are occurring on Earth, including increasing air and ocean temperatures, widespread melting of snow and ice, and rising sea levels. This fact sheet discusses key scientific.
“Climate change” means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
• Climate Change Today: what changes have already occurred and how we know humans are responsible; • Our Future Climate: what changes could happen in the future depending on the actions we take; • Limiting Future Climate Change: what is required to stop global temperature from continuing to rise.
To understand climate change, it is crucial to use a scientific definition of climate, understand the difference between weather and climate, and to study changes in the state of the climate that persist for an extended
