Alarmed at the pace of change to our Earth caused by human - induced climate change, including accelerating melting and loss of ice from Greenland, the Himalayas and Antarctica, acidification of the world's oceans due to rising CO2 concentrations, increasingly intense tropical cyclones, more damaging and intense drought and floods, including glacial lakes outburst loods, in many regions and higher levels of sea - level rise than estimated just a few years ago, risks changing the face of the planet and threatening coastal cities, low lying areas, mountainous regions and vulnerable countries the world over,

Given that the most of the melting that goes on is from the underneath (i.e. under the water) and ocean heat content is at modern highs, and the oceans have even released a bit less energy than average over the past 15 years, it is not a coincidence that ice would de line even faster during this period.

In response to increased trace gases, all replicated the qualitative response seen in other coupled ocean - atmosphere models: greater warming over land than ocean and maximum warming at high northern latitudes in winter.

Christy is correct to note that the model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).

The vulnerable nations declared that they are, «Alarmed at the pace of change to our Earth caused by human - induced climate change, including accelerating melting and loss of ice from Greenland, the Himalayas and Antarctica, acidification of the world's oceans due to rising CO2 concentrations, increasingly intense tropical cyclones, more damaging and intense drought and floods, including Glacial Lakes Outburst Floods, in many regions and higher levels of sea - level rise than estimated just a few years ago, risks changing the face of the planet and threatening coastal cities, low lying areas, mountainous regions and vulnerable countries the world over...»

Average air temperatures over the Arctic Ocean were much higher than normal for the month, reflecting unusual atmospheric conditions.

Credit: NASA] The study notes that the world's warming is greatest at high latitudes of the Northern Hemisphere, and it is larger over land than over ocean areas.

At low altitude and high temperatures (greater than 30 °C or 86 °F), over the ocean, it can reach 4.3 % or more of the atmosphere and is less dense than dry air, causing it to rise.

«In our mor recent global model simulations the ocean heat - uptake is slower than previously estimated, the ocean uptake of carbon is weaker, feedbacks from the land system as temperature rises are stronger, cumulative emissions of greenhouse gases over the century are higher, and offsetting cooling from aerosol emissions is lower.

It is hard to say with the surface data we have, but it appears that Arctic Ocean cyclones are still warmer than the High pressure over the gyre, of interest is when these temperatures will be equal, then the switch should happen when cyclones cool surface air instead.

The average temperature over land and ocean combined in May 2014 was 1.33 degrees Fahrenheit (0.74 degrees Celsius) higher than the 20th century average of 58.6 °F (14.8 °C)

According to a new study, high levels of greenhouse gas emissions could cause oceans to rise by close to two meters in total (over six feet) by the end of the century, and more than 13 meters (42 feet) from Antarctica alone by 2500.

It is usually assumed from limited information that CO2 concentrations over industrial areas are higher than the ocean values and that they are lower over vegetation.

June was warmer than average more widely over the Arctic Ocean (Figure 4b); the month saw a weather pattern similar to the Arctic Dipole, in which higher than average pressure over the American side of the Arctic drives warm air advection from the Pacific (Figure 4c).

The ocean heat uptake (OHU) figure that I took, its value over the last decade, is actually higher than if I had computed the trend over a longer - term multi-decadal period, and therefore resulted in my sensitivity estimate being higher, not lower.

Mid-continent warming will be greater than over the oceans, and there will be greater warming at higher latitudes.

Surface air temperatures for the four individual seasons of 2017 were also higher than the averages for 1981 - 2010 over many areas of land and ocean.

This is strong evidence that the SSTs were higher in the 1995 - 2005 period than they were in the 1982 - 1994 period (another explanation could be that the storms were tracking over a different portion of the ocean and / or occurred in a different portion of the hurricane seasonâ??

Further affirmation of the reality of the warming is its spatial distribution, which has largest values at locations remote from any local human influence, with a global pattern consistent with that expected for response to global climate forcings (larger in the Northern Hemisphere than the Southern Hemisphere, larger at high latitudes than low latitudes, larger over land than over ocean).

The differences are very small over most regions (less than ± 5 %), except for a small area of the equatorial Pacific Ocean, where the non-high-end models project an increase in precipitation that is about 50 per cent greater than in the high - end models.

If the rate of sea level rise over the last 20 years is as high or higher than it ever has been over the last 114 year (and is twice the 20th century average), then does this not strongly suggest that there has been no recent slowdown at all in the rate of accumulation of heat by the oceans and cryosphere?

These changes to the ocean are directly linked to anthropogenic carbon dioxide (CO2) emissions, with current atmospheric CO2 levels approximately 30 % higher than over the last 2 Myr [6].

(compare the red and black lines) As a result, precipitation over the ocean in summer is lower than it is in winter, despite the temperature in summer is higher.
