USGS Global Visualization Viewer. Lapse: Landsat Satellite Images of Climate Change, via Google Earth Engine. TIME and Space | By Jeffrey Kluger Editors note:On Nov. 29, 2016, Google released a major update expanding the data from 2012 to 2016. Read about the update here. Spacecraft and telescopes are not built by people interested in what’s going on at home.
Rockets fly in one direction: up. That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Over here is Dubai, growing from sparse desert metropolis to modern, sprawling megalopolis. It took the folks at Google to upgrade these choppy visual sequences from crude flip-book quality to true video footage. These Timelapse pictures tell the pretty and not-so-pretty story of a finite planet and how its residents are treating it — razing even as we build, destroying even as we preserve.

Key Science Concepts The Sun is the primary source of energy for Earth's climate system. The Earth's energy is in balance, or equilibrium, when Earth emits the same amount of energy as it absorbs. The climate system is dynamic and has many interrelated components.
A change in any one component can influence the equilibrium of the system and result in climate changes. Climate varies over space and time through both natural and human sources. Human activities – particularly the increase in atmospheric carbon dioxide since the Industrial Revolution – are affecting the climate system today, leading to warming temperatures globally. Evidence for variations in past climates is held in ocean and lake sediments, ice cores, corals, tree rings, and other geologic records. Climate change will have consequences for the Earth system including human society.

What is commonly referred to as acidity is the concentration of hydrogen ions in an aqueous solution.
Figure 1. The pH scale by numbers Figure 2. The percent change in acidity with falling pH values is calculated a ... Percent change in acidity Many natural processes affect acidity levels in the environment—examples include photosynthesis and respiration—so the acidity may vary by an order of magnitude or more (or in pH units, by 1 or more) as a result of natural biological, physical, and geological processes on a variety of different spatial and temporal scales.
So why are scientists concerned about such a seemingly small change in pH? Many organisms are very sensitive to seemingly small changes in pH. Common misconceptions about pH and ocean “acidification” How scientists describe the percent change in acidity If you add acid to a solution the concentration of hydrogen ions (acidity) increases and the pH decreases. High pH values Natural variability vs. long-term change. The Big Apple's Mayor Makes A Very Scary Video : Krulwich Wonders... I didn't know what to make of this when I saw it. I live in Manhattan, in a city where people bike, take buses, subways, trains, live and work in towers where they share elevators, share water, share electricity. I thought my town is setting the example for energy-efficient, communal living. And then, the guy who runs the place, Mayor Michael Bloomberg, releases a study — including (see below) a shocking video — that says, you think New York is great on energy?
You think that? YouTube The mayor has an Office of Long Term Planning and Sustainability (that includes Jonathan Dickinson and Andrea Tenorio and staff) and they decided to measure how much carbon dioxide escapes into the New York air. Then they asked, "if we took all the CO2 coming from vehicles, buildings, power plants across the city and gathered them in a clump, at one spot right next the Empire State Building, how much CO2 is emitted in a single hour? That's one hour. "Oy," as some New Yorkers like to say. Is it? Like what?
