Global warming is the result of burning fossil fuels, coal, and oil that release carbon dioxide.

The majority of scientists believe global warming is a process underwayand that it is human-induced.

What are greenhouse gasses?

Carbon dioxide, methane, and nitrous oxide.

Human activities add to the levels of greenhouse gasses, causing more problems.

Automobiles, heat from homes, businesses, factories

Global warming on human health and environment

- Global warming is a danger to a human's health.

- An increase in temperature can result in a longer life cycle for diseases

It can affect our future ability to obtain food.

As climates change, plantsand animals will change, leading to a change in the eatingpatterns of humans.

Acid rain gradually destroys almost everything it touches.

Let‘s cut down paperwork.Not trees.

PREVENT GLOBAL WARMING

car pooling auditing the energy in your home

buying fuel-efficient cars reducing the electricity in your home

planting trees recycling

CO2 levels are projected to be 30 -150% higher in 2100

slow the effect of global warming

SLOVENIA‘S POSITION ON CLIMATE CHANGE

Supranational measures are needed to find a solution.

Slovenia has achieved a great success in its environmental policy.

It has seen major progress in the cutting emissions of

greenhouse gases and reducing dependence on fossil fuels.

ahead of most of Europe and the rest of the world

Global Warming Fast Facts

Average temperatures have climbed 0.8 degrees Celsius around the world since 1880.

The 20th century's last two decades were the hottest in 400 years and the warmest for several millennia.

The Arctic

Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier.

- Polar bears are already suffering fromthe sea-ice loss.

Glaciers and mountain snows are rapidly melting
