Global temperature 1850 to 2017 in 2 minutes.

A new study shows that ocean heat content is the best way to measure global warming.

Ocean temperature as a vital sign revealing Earth's warming

This study shows that the temporal evolution of ocean heat content has a relatively high signal-to-noise ratio; therefore, it requires 3.9 years to separate the global warming trend from natural variability. Similarly, for sea level rise, 4.6 years are sufficient to detect the climate change signal. By contrast, owing to weather, the El Niño-Southern Oscillation and other natural variability phenomena embedded in the global mean surface temperature record, scientists need at least 27 years of data to detect a robust trend. 

The black line is ocean heat content, the pink is CO2 level, blue is CO2 measured at Mauna Loa.

Climate Central has an interactive sea level rise map. Enter the US coastal location of interest in the little white area at the upper right.

Ruth, is there any notification of sea rise?

Temperature anomaly map for northern hemisphere clearly shows heat from climate destabilization, and two cool spots from Greenland's meltwater.

The entire Amazon is threatened by deforestation on the fringes.

“Our study shows that the ongoing deforestation of the Amazon outskirts may have a negative impact on the entire rainforest”, says Minchao Wu.

The explanation is that deforestation affects the climate both locally and regionally, creating a vicious circle. When the trees disappear from the outskirts of the forest, it creates significant local warming. Furthermore, it changes the air circulation patterns throughout the Amazon area during the dry season.

This chain of events is self-perpetuating and creates a vicious circle with an increasingly higher risk of disrupting the balance of the entire ecosystem. The untouched inner parts of the Amazon rainforest are thus also at risk of adverse effects, even though the actual felling of trees takes place far away in the outermost areas.

“Our results indicate that this has already started to happen in the Amazon rainforest. [emphasis mine]

Deforestation in Amazon basin could disrupt the distant rainforest ...

April Climate Update from RobertScribbler We're averaging 1.21°C above preindustrial so far this year, as El Nino neutral conditions didn't cool things off as expected.

April of 2017 was considerably warmer than all past Aprils in the climate record with the single exception of 2016.

The month came in at 0.88 degrees Celsius above NASA’s 20th Century baseline and fully 1.1 degrees Celsius above 1880s averages. This measure was just 0.01 C warmer than now third warmest 2010 and 0.18 C shy of last year’s record.

The first four months of 2017 now average around 1.21 degrees Celsius warmer than 1880s ranges. This number is about tied with 2016’s overall record warmth which was spurred by a combined strong El Nino and the incredible buildup of greenhouse gasses in the Earth’s atmosphere that we have seen for over more than a century.

This year, ENSO neutral conditions trending toward the cooler side of average during the first quarter should have helped to moderate global temperatures somewhat. As is, though a slight cooling vs the first quarter of 2016 is somewhat evident, the broader, more general counter-trend cooling that we would expect following a strong El Nino is practically non-apparent.

Very strong Northern Hemisphere polar warming during the winter months appears to be a primary driver pushing overall global temperatures higher during recent months. [bold and underline mine]

Unfortunately, because of back to back mass bleaching events, scientists are telling us that the massive, impressive Australian Great Barrier Reef is now at a ‘terminal stage’—with large portions having no hope of recovery.

The UK's Met office has begun to share yearly CO2 rise predictions.

First yearly CO2 forecast predicts one of biggest rises ever

Now for the carbon dioxide forecast: levels of this gas in the atmosphere will rise by 2.5 parts per million to average 408 ppm in 2017.

And the monthly average could exceed 410 ppm for the first time during this year’s peak in May (CO2 levels rise and fall each year with seasonal changes in plant growth). The precise forecast is 409.86 plus or minus 0.61 ppm.

Not only is the CO2 concentration rising, it is rising ever faster. Levels at Mauna Loa have increased by an average of 2.1 ppm per year over the past decade, up from 0.7 ppm in the 1950s. But there are big variations from year to year.

In particular, there are larger increases during El Niño years, during which warm surface waters in the Pacific Ocean affect weather worldwide.

The predicted increase of 2.5 ppm in 2017 is well below the record 3.4 ppm rise last year, but still significantly more than the annual average of 2.1 ppm over the past decade.
