Climate Change
The world is in a climate emergency. Unless greenhouse gas emissions fall dramatically, warming could pass 2.9°C this century, which would have catastrophic consequences for life on this planet.
Climate scientists have showed that humans are responsible for virtually all global heating over the last 200 years. Human activities are causing greenhouse gases that are warming the world faster than at any time in at least the last two thousand years - making the Earth warmer than at any time in the last 100,000 years.
Many people think climate change mainly means warmer temperatures. But temperature rise is only the beginning of the story. Because the Earth is a system, where everything is connected, changes in one area can influence changes in all others. The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.

Understanding sea level rise: An expert explains
Even small increments in sea level can lead to significant coastal retreat and an increase in the frequency of coastal flooding events. In this video, Tom Mortlock, Senior Catastrophe Research Analyst at Aon and Adjunct Fellow at the UNSW Climate Change Research Centre, Sydney, delves into the critical issues of sea level rise and its far-reaching impacts on coastal regions.
The Vital Role of Early Warning Systems for Tonga and Small Island Developing States
Early warning systems serve as a lifeline for Small Island Developing States, which are highly vulnerable to extreme weather, rising sea levels, and shifting precipitation patterns. The Pacific Island of Tonga was among the earliest implementers of the Early Warnings for All initiative. Recently, the country introduced new disaster risk management legislation and was the first country globally to adopt an integrated strategy on both climate adaptation and disaster risk reduction.
