Scientists have pieced together historical records to reconstruct Arctic sea ice extent over the past 125 years. The results are shown in the figure below. The red line, showing the extent at the end of the summer melt season, is the most critical:
Arctic sea ice extent in recent years is by far the lowest it’s been, with about half of the historical coverage gone, and the decline the fastest it’s been in recorded history. Florence Fetterer, principal investigator at the National Snow and Ice Data Center, described the data reconstruction process in a guest post at Carbon Brief:

Extreme weather increases the risk of armed conflict in ethnically-diverse countries, a new study suggests.
Around 23% of conflict outbreaks in these countries over the last three decades have occurred during climate-related disasters, such as droughts and heatwaves, the paper says.
The results don’t suggest that weather extremes directly trigger conflict, the researchers say, but that they can be one of many contributing factors.
Carbon Brief speaks to a number of experts to dig a bit deeper into what has become quite a controversial field of climate research.
A host of different factors can increase the risk of armed conflict breaking out in a country. Some examples picked out by previous research include poverty, weak governance, a history of conflict, income gaps between rich and poor, and disputes over natural resources.
The new study, published in the Proceedings of the National Academy of Sciences, suggests that climate-related disasters should be added to this list.
This conclusion stems from a statistical analysis of armed conflicts and the economic damage caused by extreme weather events over the period 1980-2010.
The researchers looked at three categories of climate-related disasters. These include meteorological events (blizzard/snowstorm, hailstorm, tornado, tropical cyclone, winter storm), hydrological events (avalanche, flash flood, general flood, landslide, storm surge), and climatological events (cold wave/frost, drought, heatwave, wildfire).
The results suggest that around 9% of all armed conflicts over the past 30 years have occurred during – i.e. in the same month as – an extreme climatological event.

While most people accept the reality of human-caused global warming, we tend not to view it as an urgent issue or high priority. That lack of immediate concern may in part stem from a lack of understanding that today’s pollution will heat the planet for centuries to come, as explained in this Denial101x lecture:
So far humans have caused about 1°C warming of global surface temperatures, but if we were to freeze the level of atmospheric carbon dioxide at today’s levels, the planet would continue warming. Over the coming decades, we’d see about another 0.5°C warming, largely due to what’s called the “thermal inertia” of the oceans (think of the long amount of time it takes to boil a kettle of water). The Earth’s surface would keep warming about another 1.5°C over the ensuing centuries as ice continued to melt, decreasing the planet’s reflectivity.
To put this in context, the international community agreed in last year’s Paris climate accords that we should limit climate change risks by keeping global warming below 2°C, and preferably closer to 1.5°C. Yet from the carbon pollution we’ve already put into the atmosphere, we’re committed to 1.5–3°C warming over the coming decades and centuries, and we continue to pump out over 30 billion tons of carbon dioxide every year.
The importance of reaching zero or negative emissions
We can solve this problem if, rather than holding the amount of atmospheric carbon dioxide steady, it falls over time. As discussed in the above video, Earth naturally absorbs more carbon than it releases, so if we reduce human emissions to zero, the level of atmospheric carbon dioxide will slowly decline. Humans can also help the process by finding ways to pull carbon out of the atmosphere and sequester it.
Scientists are researching various technologies to accomplish this, but we’ve already put over 500 billion tons of carbon dioxide into the atmosphere. Pulling a significant amount of that carbon out of the atmosphere and storing it safely will be a tremendous challenge, and we won’t be able to reduce the amount in the atmosphere until we first get our emissions close to zero.

Pacific Gas and Electric (PG&E) recently started the process of shutting down the Diablo Canyon generation facility, the last active nuclear power plant in California. The power plant, located near Avila Beach on the central Californian coast, consists of two 1,100 megawatt (MW) reactors and produces 18,000 gigawatt-hours (GWh) of electricity a year, about 8.5 percent of California’s electricity consumption in 2015. It has been, up until this point, the single largest electrical generation facility in the state.
Looming over the imminent closure of Diablo Canyon is California State legislative bill SB 350, or the Clean Energy and Pollution Reduction Act of 2015. The act is a cornerstone of the state’s ongoing efforts to decarbonize its electricity grid by requiring utilities to include renewable sources for a portion of their electrical generation in future years. The mandate also requires utilities to run programs designed to double the efficiency of electricity and natural gas consumption.
But a number of significant unanswered questions remain about this ambitious energy policy, as the planned closing by 2025 of Diablo Canyon illustrates. Can utilities supply electricity around the clock using these alternative generation sources? And crucially, can energy storage technologies provide the power on demand that traditional generators have done?
Moving away from nuclear power
Nuclear power plants saw their heyday in the early 1970s and were praised for their ability to produce large amounts of electricity at a constant rate without the use of fossil fuels.
However, due to negative opinion and costly renovations, we are now observing a trend whereby long-running nuclear power plants are shutting down and very few new plants are being scheduled for construction in the United States.
Utilities are moving toward renewable electricity generation, such as solar and wind, partially in response to market forces and partially in response to new regulations that require utilities to reduce greenhouse gas emissions. In California, in particular, the shift toward renewable energy for market and environmental reasons, along with the public’s negative perception of nuclear energy, has caused utilities to abandon nuclear power.

Brexit support and climate denial have many similarities. Many Brexit Leave campaign leaders also deny the dangers of human-caused climate change. Older generations were more likely to vote for the UK to leave the EU and are more likely to oppose taking action on climate change; younger generations disagree, and will be forced to live with the consequences of those decisions. On both issues there’s also a dangerous strain of anti-intellectualism, in which campaigners mock experts and dismiss their evidence and conclusions.
With Brexit, the Leave campaign won the vote, and the UK economy is already feeling the consequences. As Graham Readfearn reported, a new group called “Clexit” (Climate Exit) has formed in an effort to similarly withdraw countries from the successful international climate treaty forged last year in Paris. As the group describes itself:
Clexit leaders are heavily involved in tobacco and fossil fuel-funded organizations, in what’s become known as “the web of denial.” The group’s president is Christopher Monckton, whose extensive misunderstanding of basic climate science was revealed in a thorough debunking by John Abraham, and whoinsists that President Obama was born in Kenya, among his many controversial and conspiratorial public statements. Its vice president is Marc Morano, who began his career working for Rush Limbaugh and is essentially the real-life version of the character Nick Naylor from the film Thank You for Smoking. Its secretary is Viv Forbes, who has been involved with coal industry for over 40 years and is associated with many fossil fuel-funded groups.
With feedback from the rest of the group’s members, Forbes prepared Clexit’s summary statement, which is full of myths and misinformation about economics, energy, laws, and climate science. It includes this expression of compassionate concern over the plight of low-lying island nations that are being engulfed by rising seas:

We know the world is warming, and we know humans are the main reason. But so what? The thing we’d really like to know is, what will the impacts be on our planet, its biodiversity, our society, our economies? It is only through understanding the impacts of climate change that action for reducing greenhouse gases can be motivated.
This is one of the reasons I was so interested in a very recent study from the University of Delaware, which addressed how penguins will fare in a warming world. The article was published in Scientific Reports and is available open access so anyone with an internet connection can read it here.
Lead author Megan Cimino and her colleagues looked at Adelie penguin populations and asked whether their years of increasing or decreasing population corresponded to warm, cold, or normal temperatures. In the Antarctic, which is where these penguins live, the situation is a bit complex because the land area is large and weather/climate changes are not consistent across the region.
For instance, large parts of the Western Antarctic Peninsula (WAP) are warming quite rapidly, amongst the most rapid in the world. On the other hand, in the East, some areas are warming just a little while others are cooling slightly. Since Adelie penguins live on the periphery of the ice sheet, they are exposed to a wide range of Antarctic climate regions.
The authors found that penguin colony declines occur preferentially in years where the sea waters are warmer than average. This is in contrast to colonies whose populations are stable or increasing – those occur in normal or cooler waters. This finding was particularly striking when Adelie penguin populations in the WAP (which is warming) were compared with populations elsewhere in the continent.
This knowledge of past penguin colony health was obtained by actual measurements, primarily satellite data which provided sea surface temperatures and ice extent. But the important extension of this work is into the future. The scientists took their current knowledge of penguin health and climate and asked what will happen to these penguins in the future.

Like a good economist, Hope hedged his bets. Plimer and Rudge had given him even odds, and Hope found a climate scientist, James Annan, who gave him 4-to-1 odds on the opposite wager:
2015 was of course hotter than 2008, so Plimer and Rudge each lost £1,000, with £1,334 going to Hope and £666 going to Annan on Hope’s hedged bet.

When I give a presentation and mention the 97% expert consensus on human-caused global warming, I’m often asked, “what’s the deal with the other 3%?”. These are the publishing climate scientists who argue that something other than humans is responsible for the majority of global warming, although their explanations are often contradictory and don’t withstand scientific scrutiny.
A few months ago, the world’s largest private sector coal company went to court, made its best scientific case against the 97% expert consensus, and lost. One of coal’s expert witnesses was University of Alabama at Huntsville climate scientist Roy Spencer - a controversial figure who once compared those with whom he disagreed to Nazis, and has expressed his love for Fox News.
Last week, Spencer wrote a white paper for the Texas Public Policy Institute (TPPI) outlining the contrarian case against climate concerns. TPPI is part of the web of denial, having received substantial funding from both the tobacco and fossil fuel industries, including $65,000 from ExxonMobil and at least $911,499 from Koch-related foundations since 1998, and over $3 million from “dark money” anonymizers Donors Trust and Donors Capital Fund.
Spencer’s arguments should of course be evaluated on their own merits, regardless of who commissioned them. However, it turns out that they have little merit on which to stand. The white paper is a classic example of a Gish Gallop – producing such a large volume of nonsense arguments that refuting all of them is too time-consuming. NASA Goddard director Gavin Schmidt rightly described Spencer’s paper as:
A mishmash of myths

Investigative journalism has uncovered a “web of denial” in which polluting industries pay “independent” groups to disseminate misinformation to the public and policymakers. The same groups and tactics were employed first by the tobacco industry, then fossil fuel companies. Big Tobacco has been to court and lost; now it’s Big Oil’s turn. Political leaders are choosing sides in this war.
Research by Inside Climate News revealed that Exxon did top notch climate science research in the late 1970s and early 1980s, which revealed the dangers its products posed via climate change. Soon thereafter, Exxon launched misinformation campaigns by funding “think tanks” and front groups to manufacture doubt about climate science and the expert consensus on human-caused global warming.
Exxon wasn’t alone. Koch Industries, Peabody Energy, and other fossil companies have similarly funneled vast sums of money to these groups. Last week, Senate Democrats, including presidential candidate Bernie Sanders and vice presidential contenders Elizabeth Warren and Al Franken signed a Resolution expressing congressional disapproval of the fossil fuel industry’s misinformation campaign.19 Senate Democrats also took to the floor of the Senate to speak out against the web of denial, with repeated references to the tobacco/fossil connections.

2014 and 2015 each set the record for hottest calendar year since we began measuring surface temperatures over 150 years ago, and 2016 is almost certain to break the record once again. It will be without precedent: the first time that we’ve seen three consecutive record-breaking hot years.
But it’s just happenstance that the calendar year begins in January, and so it’s also informative to compare all yearlong periods. In doing so, it becomes clear that we’re living in astonishingly hot times.
June 2015 through May 2016 was the hottest 12-month period on record. That was also true of May 2015 through April 2016, and the 12 months ending in March 2016. In fact, it’s true for every 12 months going all the way back to the period ending in September 2015, according to global surface temperature data compiled by Kevin Cowtan and Robert Way. We just set the record for hottest year in each of the past 9 months.
