What is the difference between climate and weather?
What is the difference between climate and weather?
Climate refers to the average weather conditions over a long period of time, while weather describes the atmospheric conditions at a particular place and time.
What are greenhouse gases and how do they influence Earth's climate?
What are greenhouse gases and how do they influence Earth's climate?
Greenhouse gases like carbon dioxide, methane, and water vapor absorb and emit infrared radiation, trapping heat in the atmosphere through the greenhouse effect.
What is the greenhouse effect and why is it important for Earth?
What is the greenhouse effect and why is it important for Earth?

Study Notes
Understanding Climate: The Warming World Around Us
Our planet Earth is a dynamic system, constantly undergoing changes. One of the most pressing and widely-discussed shifts in recent decades is the alteration in our climate, a consequence of complex interactions between natural and human-made factors.
Climate vs. Weather
Before diving deeper into the topic, it's essential to clarify the difference between climate and weather. Climate refers to the average weather conditions over a long period of time, reflecting the collective impact of factors such as temperature, precipitation, humidity, and wind patterns. Weather, on the other hand, describes the atmospheric conditions at a particular place and time.
Greenhouse Gases
One of the critical factors influencing Earth's climate is the presence of greenhouse gases. These gases, like carbon dioxide (CO2), methane (CH4), and water vapor (H2O), absorb and emit infrared radiation, effectively trapping heat in the atmosphere. This process is often referred to as the greenhouse effect and is a natural occurrence that helps keep our planet warm enough to support life. However, human activities, particularly the burning of fossil fuels, have led to an increase in greenhouse gas concentrations, thus intensifying the greenhouse effect.
Global Temperature Rise
The consequence of enhanced greenhouse gas concentrations is the global temperature rise. This trend has been observed since the 19th century, with the 20 warmest years on record occurring since 1981, with the five warmest years all taking place in the last decade. The UN's Intergovernmental Panel on Climate Change (IPCC) reports that human activities are responsible for most of the observed global warming since the mid-20th century.
Climate Impacts
Rising temperatures and shifting climate patterns have led to several consequences, including an increase in extreme weather events, such as droughts, heatwaves, and hurricanes. Melting ice caps and rising sea levels are also concerns, as they threaten coastal communities and endanger ecosystems. For example, the Greenland ice sheet lost 3 trillion tons of ice between 1992 and 2018, contributing to a 0.8-inch rise in sea level.
Mitigation and Adaptation
To address the challenges posed by climate change, nations are implementing policies and strategies aimed at mitigation (reducing greenhouse gas emissions) and adaptation (preparing for and managing the impacts of climate change). The Paris Agreement, an international treaty agreed to by nearly every country in the world, aims to limit global warming to well below 2°C (3.6°F) above pre-industrial levels and to pursue efforts to limit the increase to 1.5°C (2.7°F).
In conclusion, understanding climate is crucial to appreciating the dynamic and complex processes that influence our planet. Climate change is a pressing global issue that requires collective effort and ongoing investigation. By gaining knowledge about climate, we empower ourselves to make informed decisions and foster an environment that supports the health and wellbeing of our planet and its inhabitants.
