WMO will issue its full Statement on the State of the Climate in 2017 in March which will provide a comprehensive overview of temperature variability and trends, high - impact events, and long - term indicators of climate change such as increasing carbon dioxide concentrations, Arctic and Antarctic sea ice, sea level rise and ocean acidification.

The risk facing humanity is that climate change could spiral out of control and it will no longer be possible to arrest trends such as ice melting and rising sea level.

A positive trend for dispersed sea ice extent in the Antarctic in winter amid rising winter temperature in the southern hemisphere is not matched by trends in concentrated sea ice extent and the degree of dispersion and is discounted as spurious.

Over the long - term, melting of the West Antarctic Ice Sheet could yield as much as 10 to 14 feet of global average sea level rise, with local sea level rise varying considerably depending on land elevation trends, ocean currents and other factors.

A survey of trends in dispersed and concentrated sea ice extent in the Arctic in the northern summer and northern winter and in the Antarctic in the southern summer and southern winter for the period 1979 - 2015 shows a negative trend in dispersed and concentrated sea ice extent in the Arctic in the northern summer amid rising surface temperature in the northern hemisphere.

Researchers found that sea level rise in the West Antarctic Ice Sheet may reach up to three meters if current instability trends persist.

That's consistent with other research on longer term trends in Greenland ice, and how these trends contribute to sea level rise.

Since current ice melt data could indicate variable climate trends and aren't necessarily part of an accelerating trend, the study warned that predictions of future sea - level rise should not be based on measurements of glacial loss» Daily Mail.

ocean temperatures, widespread melting of snow and ice, and rising global average sea level,» are three disjoint sources of confirmation that give us reliable enough trend information to establish consilience about what we may say after 2005 on HadCRUT4.

The oceans have risen by around 2.5 cm over the last decade, emphasising just how warm the seas and the atmosphere have become already As ice caps glaciers and sea ice show us the trend in rather obvious ways, scientists studying the phenomena have been shocked.

«Many of the events that made 2012 such an interesting year are part of the long - term trends we see in a changing and varying climate — carbon levels are climbing, sea levels are rising, Arctic sea ice is melting, and our planet as a whole is becoming a warmer place,» said Acting NOAA Administrator Kathryn D. Sullivan, Ph.D. «This annual report is well - researched, well - respected, and well - used; it is a superb example of the timely, actionable climate information that people need from NOAA to help prepare for extremes in our ever - changing environment.»

Global Warming Theory «Completely Disconnected From the Observations» Extensive analysis of temperature trends in the Arctic reveals that there has been no detectable long - term change since the beginning of the 20th century, and thus predictions of a sea ice - free Arctic in the coming decades due to dramatically rising temperatures are not rooted in observation.

These trends in extreme weather events are accompanied by longer - term changes as well, including surface and ocean temperature increase over recent decades, snow and ice cover decrease and sea level rise.

To say nothing of the warming trends also noticed in, for example: * ocean heat content * wasting glaciers * Greenland and West Antarctic ice sheet mass loss * sea level rise due to all of the above * sea surface temperatures * borehole temperatures * troposphere warming (with stratosphere cooling) * Arctic sea ice reductions in volume and extent * permafrost thawing * ecosystem shifts involving plants, animals and insects

2) The sea ice (long - term) trend in Antarctica over the past 30 years has undisputedly been one of steady rise.

The G refers to global, thus the MEAN global T must rise, the mean sea ice extent must decrease, global sea level trend must increase, global tornadoes must rise, global floods must increase, the rate of global sea riseust rise, and all the global change MUST be catastrophic, and clearly outside of recent past global flux.

For example, additional evidence of a warming trend can be found in the dramatic decrease in the extent of Arctic sea ice at its summer minimum (which occurs in September), decrease in spring snow cover in the Northern Hemisphere, increases in the global average upper ocean (upper 700 m or 2300 feet) heat content (shown relative to the 1955 — 2006 average), and in sea - level rise.

If you strip the scientific context of a globally rising temperature trend, you could argue that observed melting of sea ice is just some noise in the data, part of natural variation.

With these trends in ice cover and sea level only expected to continue and likely worsen if atmospheric carbon dioxide levels continue to rise, they could alter the stresses and forces fighting for balance in the ground under our feet — changes that are well - documented in studies of past climate change, but which are just beginning to be studied as possible consequences of the current state of global warming.

Jim D, if you and others like you aren't willing to do what must be done to greatly increase the price of carbon, then all your talk of ice sheet melting, sea level rise, climate tipping points, global temperature trends, the earth's paleoclimate history, and climate model projections — all of that talk is mere Kabuke theater.

And since we have had rising sea level over last couple centuries, and this generally indicates warming global ocean volume, I expect this trend to continue for the next century [most likely] and due to warming oceans continuation of tread of less polar sea ice.

In light of trends showing a likely 3 °C or more global temperature rise by the end of this century (a figure that could become much higher if all feedback processes, such as changes of sea ice and water vapor, are taken into account) that could result in sea level rises ranging from 20 to 59 cm (again a conservative estimation), Hansen believes it is critical for scientists in the field to speak out about the consequences and rebuke the spin offered by pundits who «have denigrated suggestions that business - as - usual greenhouse gas emissions may cause a sea level rise of the order of meters.»

Melting glaciers and sea ice are particularly worrisome trends because they trigger critical secondary effects, notably including increasing rates of sea - level rise.

This expansion, combined with the melting of land - based ice, has caused global average sea level to rise by roughly 7 - 8 inches since 1900 — a trend that is expected to accelerate over coming decades.

«Environmental scientists have been saying for some time that the global economy is being slowly undermined by environmental trends of human origin, including shrinking forests, expanding deserts, falling water tables, eroding soils, collapsing fisheries, rising temperatures, melting ice, rising seas, and increasingly destructive storms,» says Brown, President and Founder of the Earth Policy Institute, a Washington, D.C. - based independent environmental research organization.
