Environment climate question, a short article that compares the present scientific approach with what some experts used to say in 1970, that is 50 years ago
Man has to awaken to wonder – and so perhaps do peoples. Science is a way of sending him to sleep again.
Ludwig Wittgenstein
Matter, this revolutionary entity of the universe, which aggregates and disintegrates at will without ever asking anyone’s permission, creating on the contrary a lot of problems for everyone!
Carl William Brown
A butterfly flapping its wings in Brazil can produce a tornado in Texas.
Edward Lorenz
To solve the climatological problems it is necessary to study the mathematics of coupled nonlinear differential equations and the experiments to be carried out so that this mathematics corresponds to reality.
Antonino Zichichi
The earth, our home, is beginning to look more and more like an immense pile of filth.
Pope Francis
Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.
Bill Gates
Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.
Bill Nye
We must look at the present state of the universe as the effect of its previous state and as the cause of its future state. An intelligence capable of knowing all the forces that act in nature in a certain instant and the instantaneous positions of all objects in the universe, would be able to understand in a single formula the motion of the largest bodies as well as that of the lighter atoms, as long as his intellect was powerful enough to be able to analyze all the data. Nothing would be unknown to him, the future as well as the past.
Pierre Laplace
Nowadays the overwhelming majority of scientists agree that climate change is real and caused by humans. Studies show that 97 percent (or more) of climate scientists who are actively publishing agree that climate change is likely due to human activity. Nearly 200 scientific organizations across the globe have issued statements that publicly endorse this view.
Global temperatures during some of the past interglacial periods have exceeded the average temperatures we observe today, although you would have to go back more than three million years to find a period that was clearly warmer than today. Temperatures in the most recent decade have now exceeded the warmth of the previous Eemian interglacial.
Global warming is an environmental issue because it affects the natural environments of various parts of the world. It does so in ways that hurt humans directly and in ways that alter environmental conditions for nature. Global warming brings about changes in the environment in many places. There are many examples of how it does this, it can melt the polar ice caps for instance.
Warmer weather is increasing the risk of long droughts and severe forest fires as it is happening in Australia or some American states, but at the same time more flooding due to climate changes is the greatest risk for some other countries, like the UK for example.
The average global temperature has risen by 1.69 degrees F (0.94 degrees C) since the twentieth century with more significant warming toward the poles than in the equatorial region. Although most locations on the planet have recorded increased temperatures since 1900, changes in global ocean and atmospheric circulation patterns have created small-scale temperature decreases in a few local regions.
The gases responsible for the greenhouse effect and therefore for the global warming are CO2, CH4 and water vapor. The electricity and heat production sector emits the largest percentage of global greenhouse gas emissions at 25%. Agriculture, forestry, and other land use sector is a close second at 24%.
For the past few decades, scientists have had the benefit of global satellite data. We have accurate ground-based measurements that reach back just over a century. “Proxy” methods, such as tree ring and ice core analysis, are used to reconstruct climate records before the rise of modern instruments.
Global warming, also known as climate change, is caused by a blanket of pollution that traps heat around the earth. This pollution comes from cars, factories, homes, and power plants that burn fossil fuels such as oil, coal, natural
