What Causes Climate Change?

Human Activities Are The Main Cause

Renewable energy – powering a safer and prosperous future

Renewable energy is key to solving the climate crisis – cutting pollution, lowering costs, creating millions of jobs, and building stronger, more secure economies. Discover five reasons why accelerating the transition to clean energy is key to a safer, healthier and more prosperous future for all.

Main Causes of Climate Change

• Burning Fossil Fuels - coal, oil, natural gas for energy
• Deforestation - cutting down forests that absorb CO2
• Agriculture - livestock produce methane gas
• Transportation - cars, trucks, planes, ships
• Industry - factories making cement, steel, plastic
• Waste - landfills release methane as garbage breaks down

The world’s addiction to fossil fuels is one of the greatest threats to global stability and prosperity.

The main activity of the IPCC is the preparation of reports assessing the state of knowledge of climate change. These include assessment reports, special reports and methodology reports. To deliver this work programme, the IPCC holds meetings of its government representatives, convening as plenary sessions of the Panel or IPCC Working Groups to approve, adopt and accept reports. Plenary Sessions of the IPCC also determine the IPCC work programme, and other business including its budget and outlines of reports. The IPCC Bureau meets regularly to provide guidance to the Panel on scientific and technical aspects of its work. The IPCC organizes scoping meetings of experts and meetings of lead authors to prepare reports. It organizes expert meetings and workshops on various topics to support its work programme, and publishes the proceedings of these meetings.  To communicate its findings and explain its work, the IPCC takes part in outreach activities organized by the IPCC or hosted by other organizations, and provides speakers to other conferences. More information on sessions of the IPCC, its Working Groups and the Bureau can be found in the Documentation section.

Shockin Fact: Humans have increased CO2 levels by 50% since the Industrial Revolution. Current levels are the highest in 800,000 years.

Natural Causes (Smaller Impact)

• Volcanic eruptions - release ash and gases
• Changes in Earth's orbit - natural cycles over thousands of years
• Solar activity - small changes in sun's energy

Natural causes alone would actually cool the Earth. Human causes are why we are warming.
