I Am Concerned About Climate Change

AAAS Reaffirms Statements on Climate Change and Integrity
4 December 2009 by: AAAS.org staff report

The American Association for the Advancement of Science (AAAS) has reaffirmed the position of its Board of Directors and the leaders of 18 respected organizations, who concluded based on multiple lines of scientific evidence that global climate change caused by human activities is now underway, and it is a growing threat to society.

“The vast preponderance of evidence, based on years of research conducted by a wide array of different investigators at many institutions, clearly indicates that global climate change is real, it is caused largely by human activities, and the need to take action is urgent,” said Alan I. Leshner, chief executive officer of AAAS and executive publisher of the journal Science.

What happened to global warming?

@MrBrownstone The term climate change has now become more widely used. Both terms address the same condition: carbons being expelled into the atmosphere by human activity causing changes in world climate.

@badminton Sounds like a lie

@MrBrownstone The following page lists the nearly 200 worldwide scientific organizations that hold the position that climate change has been caused by human action.

So all of these scientific organizations are participating in a grand conspiracy are they? If they wanted money they would get much more working for oil companies.

@MrBrownstone Climate change is used instead of global warming because global warming only explains one aspect of the problem. More and more people are starting to realize that the people denying that global warming is happening are full of it. It is one thing to listen to people argue based on theories but another to see the changes with your own eyes. The most obvious sign is the oceans rising because they act as a heat sink for the changing climate, the warmer water causes sea level rise by itself but it gets worse because all the melted sea and land ice. It is hard not to notice flooding in Miami on sunny days when there is a high tide. Expect sea level rise in Miami to be 14 to 26 inches higher than 1992 levels by 2060. If we were not watching it happen you might could argue against it.

@Subsumedpat melting Ice won’t raise the sea level. Just like when ice melts in your cup of soda,you don’t end up with an overflowing cup

@MrBrownstone You are correct for floating sea ice. However, ice that melts over land in Greenland and Antarctica definitely raises global sea levels. It is equivalent to pouring in more soda in your example, and you do end up with an overflowing cup.

@MrBrownstone I am sorry but you have been misinformed ,melting floating sea ice does not contribute near as much as melting land ice but it does contribute. Melting water from sea ice and floating ice shelves could add 2.6% more water to the ocean than the water displaced by the ice. The common misconception that floating ice won’t increase sea level when it melts occurs because the difference in density between fresh water and salt water is not taken into consideration. Freshwater actually has greater volume than an equivalent weight of saltwater. Thus, when freshwater ice melts in the ocean, it contributes a greater volume of melt water than it originally displaced.
