On one side we relish the magnificence of nature but there is no such force to defend or save it from any disaster. With time it is slaying every little part of this elegant creation.
Draft - 1. The observations of how our planet has changed are real. What they are telling us about our future is open for interpretation. The majority of climate scientists think they paint a picture of a rapidly warming at least in any geological or ecological sense world, where the rate of warming over the last few years has been accelerating.

Since the slowdown in surface warming over the last 15 years has been a popular topic recently, I thought I would show results for the lower tropospheric temperature (LT) compared to climate models calculated over the same atmospheric layers the .

As such it is impossible to make exact predictions how climate will change over the next few years or decades. However, we can consider how climate may continue to change in terms of risk.
This is discussed in the concluding Section 7. How should we react to the observed global warming? The observations show a growing risk to human society from runaway global warming, and they beg explanation. It is also the case that the Arctic as a whole appears to be warming at something like twice the rate of the rest of the planet.
This essay focuses on observations of what appears to be the start of runaway warming in the Arctic that may have profound effects on global climates over the next few years; and a plausible cause - the warming driven release of methane gas from permafrost forming a strong greenhouse cap over the Arctic Ocean.
Evidence shows that over the last few years winter cooling over the Arctic Ocean has been significantly retarded when the sun is below the horizon for months at a time when heat absorbed over summers with 24 hour daylight should be radiating away to outer space.
The observations summarized here are based on computerized analyses of many millions of data points collected per day covering the entirety of the satellite era, beginning in To encapsulate summaries with the minimum of text and numeric data, I have used a number of animated maps where primary data is encoded in color.
Changes in this data over time intervals ranging from days to months and years are shown as a stack of gif images forming short movies. To me, in addition to a continuing rise in arctic temperatures, the most conspicuous indication that we may have passed a tipping point where arctic warming is increasing at an ever faster rate as shown by the graph below.
This depicts changes in the areas extents covered by sea ice on the whole planet. Over the half year on each day of the year the area of the globe covered by sea ice has been by far the lowest it has ever been in the satellite era for those days and from 7 January until around March - a period of two whole months - there has been less sea ice on the planet since the previous record low recorded in mid February Such a major deviation from "normal" indicates there are currently some serious climate changes taking place in the world.

The red shaded area of the graph highlights daily extents lower than any low extent recorded in any previous year since The inset graph shows changes in the deviations from the mean value over the last 10 years.
Global monitoring agencies Several government agencies around the world use various observational tools to measure weather. These include simple recording thermometers measuring ground and air temperature together with wind speeds and direction and cloud cover at designated weather stations, balloon lifted radiosondes to plot temperature profiles of the atmosphere above the weather stations, similar measurements made by ships and floating buoys at sea, and a variety of satellite-based remote sensing systems.
Together with electronic communications and automated data processing their daily and more frequent readings provide a global picture of weather and climate.
The kinds of observations collected include temperature at a variety of heights above the ground, sea surface temperature, precipitation and clouds, location and depths of ice on land and over the ocean, mean sea level pressure and pressure at a variety of elevations above mean sea level, precipitable water, surface winds, jet stream winds and a variety of other variables collected on a more limited basis, such as concentrations of various kinds of gases in the atmosphere.
These observations provide input for a variety of weather prediction and climate change models where values and changes can be visualized on a global basis. Three particularly useful services automatically process and digest the millions of individual daily observations into consistent and coherent global visualizations: These show daily variations in weather and long term histories of climate change on global and regional scales.The Energy Racket.
