[...] It’s really a pleasure for me to be able to be back in Jakarta, back in Indonesia, where you have one of the richest ecosystems on Earth. And you live in a country that is at the top of the global rankings for both marine and terrestrial biodiversity, and you have a human ecosystem that includes some 300 ethnic groups, speaking at least 700 languages – extraordinary place.

But because of climate change, it is no secret that today, Indonesia is also one of the most vulnerable countries on Earth.

This year, as Secretary of State, I will engage in a series of discussions on the urgency of addressing climate change – particularly on the national security implications and the economic opportunities. And I want you to think about those. But I wanted to start right here, in Jakarta, because this city – this country – this region – is really on the front lines of climate change. It’s not an exaggeration to say to you that the entire way of life that you live and love is at risk. So let’s have a frank conversation about this threat and about what we, as citizens of the world, need to be able to do to address it.

Some time ago I travelled to another vibrant city – a city also rich with its own rich history – Rio de Janeiro, Brazil. And I was there, sitting in a big room, surrounded by representatives from about 170 countries. We listened as expert after expert after expert described the growing threat of climate change and what it would mean for the world if we failed to act. The Secretary General of the conference was – he was an early leader on climate change, a man by the name of Maurice Strong, and he told us – I quote him: “Every bit of evidence I’ve seen persuades me that we are on a course leading to tragedy.”

Well, my friends, that conference was in 1992. And it is stunning how little the conversation has really changed since then.

When I think about the array of global climate – of global threats – think about this: terrorism, epidemics, poverty, the proliferation of weapons of mass destruction – all challenges that know no borders – the reality is that climate change ranks right up there with every single one of them. And it is a challenge that I address in nearly every single country that I visit as Secretary of State, because President Obama and I believe it is urgent that we do so.

And the reason is simple: The science of climate change is leaping out at us like a scene from a 3D movie. It’s warning us; it’s compelling us to act. And let there be no doubt in anybody’s mind that the science is absolutely certain. It’s something that we understand with absolute assurance of the veracity of that science. No one disputes some of the facts about it. Let me give you an example. When an apple separates from a tree, it falls to the ground. We know that because of the basic laws of physics. No one disputes that today. It’s a fact. It’s a scientific fact. Science also tells us that when water hits a low enough temperature, it’s going to turn into ice; when it reaches a high enough temperature, it’s going to boil. No one disputes that. Science and common sense tell us if you reach out and put your hand on a hot cook stove, you’re going to get burned. I can’t imagine anybody who would dispute that either.

So when thousands of the world’s leading scientists and five reports over a long period of time with thousands of scientists contributing to those reports – when they tell us over and over again that our climate is changing, that it is happening faster than they ever predicted, ever in recorded history, and when they tell us that we humans are the significant cause, let me tell you something: We need to listen.
