For a long time, the scientists have been telling us global warming increases the temperature of the top layer in the ocean, and that causes the average hurricane to become a lot stronger. So, the fact that the ocean temperatures did go up because of global warming, because of man-made global warming, starting around in the '70s, and then we had a string of unusually strong hurricanes outside the boundaries of this multi-decadal cycle that is a real factor; there are scientists who point that out, and they're right, but we're exceeding those boundaries now.
Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000.
Do politicians understand just how difficult it could be, just how devastating rises of 4C, 5C or 6C could be? I think, not yet
Narragansett Bay waters are getting warmer -- 4 degrees Fahrenheit warmer in the winter since the 1960s.
We know the surface temperature of the Earth is warming. It has risen by .6 degrees Celsius over the past 100 years. There was a warming trend from the 1890s to the 1940s, cooling from the 1940s to the 1970s, and then sharply rising temperatures from the 1970s to today.
The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.
… there is little evidence as to how it has come about, and no clear proof that the process is continuing in any considerable degree at the present time.
Not all eminent scientists were fully satisfied with Darwin's theory of evolution. Father of Genetics
The average global temperature has increased by about 0.8 degrees Celsius since 1880, with two-thirds of the warming occurring since 1975.
We'd already lost the possibility of stopping global warming entirely. That hasn't been in the cards for a long time. The triumph of Trump probably means that we're not going to be able to stop it at the two-degree mark that the world had been aiming for. That's very bad news, mostly because the planet seems to be more sensitive than we thought to even small increases in temperature.
The last time the world was three degrees warmer than today-which is what we expect later this century-sea levels were 25m higher. So that is what we can look forward to if we don't act soon.
The five warmest years over the last century occurred in the last eight years.
There is no doubt that we should take solar radiation into account. We have seen ground temperatures rising since 1975, and it is important to know to what extent that has been caused by the sun or by carbon dioxide.
The laws of thermodynamic s are such that if the water is getting warmer - and I believe it is - the energy of the weather is going to go up.
It has become very difficult for anyone to argue that observed global warming is natural variability. We have good reason for being able to say that the world will be warmer by about a quarter of a degree in the next decade. It's the same reason we had 10 years ago when we said that the 1990s would be warmer than the 1980s: The planet is out of equilibrium.
The important point there is that when people talk about a mean temperature rise of say two, three or four degrees that's a sort of global average which really is a signature of large scale change in climatic patterns.
In Australia, average temperatures have risen almost one degree since 1910, and each decade since the 1940s has been warmer than the one before. That warming is real. Its consequences are real. And it will change our lives in real and practical ways.
The extraordinary summer heatwave of 2003 in Europe resulted in over 35,000 extra deaths.
The world has not warmed up very much since the millennium.
On average, global warming is not going to harm the developing world.
The ten hottest years in the atmospheric record, going back only 160 years, have been in the last eleven years.
But heat can also be produced by the friction of liquids, in which there could be no question of changes in structure, or of the liberation of latent heat.
Failure to curb temperature increases will impact all countries, Ireland included, but with the most immediate and drastic effects being felt, in many instances, by the most vulnerable countries and communities.
You think the weather is weird now? Just wait. A new MIT study, just published in a peer-reviewed journal, projects that the Earth could see warming of more than 9 degrees F by 2100 - more than twice earlier projections.
It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up.
When you analyze all the data, there is a warming trend according to science. But the jury is out on the degree of how much is manmade.
