“Estamos aqui porque o mundo está a enfrentar uma grave crise climática. A rutura do clima está a acontecer agora e está a acontecer com todos nós. Estamos numa batalha pelas nossas vidas. Mas é uma batalha que ainda podemos vencer”, declarou António Guterres, durante a Reunião do Clima de Abu Dhabi , em junho de 2019.

“We are here because the world is facing a serious climate crisis. The climate disruption is happening now and it is happening to all of us. We are in a battle for our lives. But it is a battle that we can still win”, declared António Guterres, during the Abu Dhabi Climate Meeting, in June 2019.

We live in a decisive moment for the human species!

Science shows that:

The concentration of greenhouse gases in the Earth's atmosphere is directly linked to the Earth's global average temperature;

The concentration of these gases has steadily increased, as have global temperatures, since the time of the Industrial Revolution;

The most abundant greenhouse gas, responsible for about two-thirds of greenhouse gases, is carbon dioxide (CO2), and largely results from the burning of fossil fuels.

Over time:

- From 1880 to 2012, the average global temperature increased by 0.85 °C.

- The oceans warmed, the amounts of snow and ice decreased, and sea levels rose.
- From 1901 to 2010, the average sea level rise was 19 centimeters as the oceans expanded due to warming and melting ice. The extent of sea ice in the Arctic has declined in every successive decade since 1979.

Five future impacts:

- Under all emission scenarios, temperatures by 2040 will reach 1.5°C above 1850-1900 levels.
- The Arctic is likely to be virtually ice-free in a September, at least on one occasion before 2050 in all scenarios evaluated.
- Some extreme events "unprecedented in the historical record" will happen more frequently with warming of 1.5°C
- Extreme sea-level events that occurred once a century in the recent past are expected to occur at least annually in more than half of tidal measurement sites by 2100.
- There will likely be increases in wildfires in many regions.
