A Quote by Martin Rees

Issues relating to global health and sustainability must stay high on the agenda if we are to cope with an ageing and ever-increasing population, with growing pressure on resources, and with rising global temperatures. The risks and dangers need to be assessed and then confronted.
We have many advantages in the fight against global warming, but time is not one of them. Instead of idly debating the precise extent of global warming, or the precise timeline of global warming, we need to deal with the central facts of rising temperatures, rising waters, and all the endless troubles that global warming will bring. We stand warned by serious and credible scientists across the world that time is short and the dangers are great. The most relevant question now is whether our own government is equal to the challenge.
We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.
Climate change is the greatest threat to humanity, perhaps ever. Global temperatures are rising at an unprecedented rate, causing drought and forest fires and impacting human health.
Most challenges arise suddenly, with little warning. Climate change is different. For decades, we've known why global average temperatures are rising, why greenhouse gas concentrations are increasing, why the oceans are warming and weather patterns are growing more extreme.
Now we stand at our own crossroads, looking out upon two futures: one with rising temperatures, rising oceans, and rising violence on a hot and strip-mined planet and another with expanding organic harvests, growing solar arrays, and deepening global partnerships on a green and thriving Earth.
Environmental pollution, terrorism, and many other global threats do not stop at borders. We all bear global responsibility and thus need a global identity to enable us to cope with them. We must learn to integrate different levels of identity in ourselves. What matters is not either/or, but both/and.
The climate crisis is the greatest challenge humanity has ever faced. From not only the warming of the earth with higher global temperatures, but also from strengthening storms and expanding droughts to melting ice and rising seas, the costs of carbon pollution are already being felt by governments, corporations, taxpayers and families around the world. The climate crisis will affect everything that we love and alter the course of our future. Now, more than ever, we must come together to solve this global crisis. We must act decisively, rise to the occasion and solve this monumental challenge.
Either the Earth System would undergo major phase transitions as a result of unchecked human pressure on nature's capacities and resources or a "Great Transformation" towards global sustainability would be initiated in due course. Neither transitions nor transformations will be manageable without novel forms of global governance and markets.
We need to see the connection between global warring and global warming, and it's oil. Sustainability is the path to peace.
Are global temperatures rising? Surely, they were rising from the late 1970s to 1998, but 'there has been no net global warming since 1998.' Indeed, the more recent numbers show that there is now evidence of significant cooling [...] Mankind is responsible for just a fraction of one percent of the effect from greenhouse gases, and greenhouse gases are not responsible for most of what causes warming (e.g., the Sun).
There are many issues in the global economy in general and in the western economy as well: population ageing, drop in labour productivity growth rates. This is obvious. The overall demographic situation is very complicated.
Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.
As a global community, we have to start thinking more seriously about whether there are limits to what our earth can bear and if we're willing to cope with the struggle for limited resources, which only seem to increase as our population does.
We face the gravest threat that civilization has ever confronted. It's global in nature and requires a global solution. Increased CO2 emissions anywhere, whether from China or the United States or from one of the countries that is burning its forests like Brazil or Indonesia.
Stop costly new regulations that would increase unemployment, raise consumer prices, and weaken the nation's global competitiveness with virtually no impact on global temperatures.
Hong Kong needs population growth to cope with a rapidly ageing population.
