Yuval Noah Harari Quotes

All the major problems of the world today are global in essence, and they cannot be solved unless through some kind of global cooperation. It's not just climate change, which is, like, the most obvious example people give. I think more in terms of technological disruption.

We collaborate with other countries on issues like public health and climate change because we understand these issues affect our collective welfare.

The problems that the world faces - from nuclear proliferation to climate change - can't be tackled by the West alone. They need a coalition of not just West and East, but they need a coalition of Christian and Jew and Muslim.

Issues of energy, climate change, nuclear arms control and non-proliferation are all big deals. These are problems that we have to get right globally, not just nationally, and there are big benefits in cooperating, in terms of sharing costs, in terms of sharing risks, in terms of propagating the best answers.

We are all in this together. We will all make it or none of us will make it. If everyone cleans up their act except one big ole country, it isn't going to work.

We need a greening of globalisation.

You look at the large problems that we face - that would be overpopulation, water shortages, global warming and AIDS, I suppose - all of that needs international cooperation to be solved.

We know who speaks for the nations. But who speaks for humanity? Who speaks for earth?

It is simply not feasible for sovereignty to be exercised unilaterally by individual nation-states, however powerful. It is a principle which will yield only slowly and reluctantly to the imperatives of global environmental cooperation.

International cooperation is vital to keeping our globe safe, commerce flowing, and our planet habitable.

What I think is if the world is in some difficulty - about climate change, about economics - then we had better make sure that 100 per cent of every brain available on the planet is working at full pelt to try to sort these things out.

If we invest in researching and developing energy technology, we'll do some real good in the long run, rather than just making ourselves feel good today. But climate change is not the only challenge of the 21st century, and for many other global problems we have low-cost, durable solutions.

What governments and people don't realise is that sometimes the collective interest - the international interest - is also the national interest.

We want to promote people-to-people exchanges so that China and the United States can really join together, not just to solve the problems of China or the United States, but some of the big problems facing the entire world. From climate change to famine to even terrorism.

I'm a technological optimist in that I do believe that technology will provide solutions that will allow the world in 2050 to support 9 billion people at an acceptable standard of living. But I'm a political pessimist in that I am concerned about whether the science will be appropriately applied.

Clean air and a healthy climate benefit all of us, but it will take a diverse coalition to step up to the threat posed by unchecked climate change.

We don't need a War on Carbon. We need a new prosperity that can be shared by all while still respecting a multitude of real ecological limits - not just atmospheric gas concentrations, but topsoil depth, water supplies, toxic chemical concentrations, and the health of ecosystems, including the diversity of life they depend upon.

Climate change and ozone depletion are two global issues that are different but have many connections. In the ozone depletion case, we managed to work with decision makers effectively so that an international agreement called the Montreal Protocol was achieved that essentially solved the ozone depletion problem.

The world can't have a global solution to climate change with U.S. action alone; and the world can't have a global solution without U.S. action.

We really need to kick the carbon habit and stop making our energy from burning things. Climate change is also really important. You can wreck one rainforest then move, drain one area of resources and move onto another, but climate change is global.

We will never end poverty if we don't tackle climate change.

Individual scientists cannot do much on their own. Heads of nations, corporates, and economic giants should recognise the criticality of it.

If the amount of money going into the war economy were invested in landscape restoration, we would be in a far more positive position. It may get a little dire before we pull together, but I think when the prosperous nations, and in particular the U.S., realize they're wrecking their own kids' lives, there will be a mass change in value.

I have been fighting climate change for two decades, and people often ask me how I remain hopeful in the face of extreme weather and grim forecasts. The answer is simple: I see countless solutions spreading across the nation and across the world. But we need more investment.

But Australia faces additional regional and global challenges also crucial to our nation's future - climate change, questions of energy and food security, the rise of China and the rise of India. And we need a strong system of global and regional relationships and institutions to underpin stability.
