The hottest year on record

December 26, 2023 By EarthWise Leave a Comment

Barring some sort of massive global deep freeze late in the year, it was increasingly obvious by November that 2023 was going to be the hottest year ever recorded.  After analyzing data that showed the world saw its warmest ever November, experts around the world made the call early in December.

According to the European Union’s Copernicus Climate Change Service, from January to November 2023, global average temperatures were the highest on record – 1.46 degrees Celsius or 2.6 degrees Fahrenheit above the pre-industrial average.  Given that the Paris Climate Accord has the goal of keeping warming below 1.5 degrees Celsius, 2023 has been an alarmingly hot year.

November itself was 1.75 degrees warmer than the pre-industrial average.  The average surface air temperature for the planet was 14.22 degrees Celsius or about 57.6 degrees Fahrenheit.  Now 57 degrees doesn’t sound all that warm, but we are not accustomed to thinking in terms of the average temperature for the entire planet.  Keep in mind that the planetary average includes Antarctica and the polar north. The year as a whole had six record-breaking months and two record-breaking seasons. 

There is no reason to hope that the warming in 2023 was an anomalous occurrence and that 2024 is apt to be cooler.  With an El Niño in place in the Pacific, the new year might even be warmer than the previous one.  With continued warming, extreme weather events are likely to become even more frequent and intense, exacerbating the damage and loss of life from droughts, floods, hurricanes, and wildfires.

Solar Power In Australia | Earth Wise

October 13, 2021 By EarthWise Leave a Comment

Solar power generation increasing in Australia

Historically, the electricity sector in Australia has been dominated by coal-fired power stations.  Even now, coal accounts for about 60% of Australia’s electricity generation.  But since 2005, wind power and rooftop solar have led to a fast-growing share of renewable energy in total electricity generation.

Australia is the second-largest exporter of coal in the world and has proven reserves equivalent to over 1,200 times its annual consumption.  Australia is home to four of the world’s ten biggest coal mines.  But despite this abundant resource, the country is increasing its use of renewable energy.

For just a few minutes on a sunny Sunday afternoon in August, more than half of Australia’s electricity came from solar power.  Low demand and sunny skies resulted in the contribution from coal dropping to a record low of 9,315 MW while solar power provided 9,427 MW.

In 2020, 24% of Australia’s electricity came from renewable energy, up from 21% the year before.  The increase was driven by a boom in solar installation.

Australia is still a long way from meeting its commitments under the Paris Climate Change agreement.  The country ultimately needs 51 GW of new renewable energy generation by 2042 but only 3 GW of new wind and solar projects have been committed to date.

Overall, Australia has promised what has been described as the fastest energy transition in the world.  It is all very ambitious, but Australia has a lot of work to do.

Not Such Climate Champions | Earth Wise

Problems with the Paris Climate Accord

The goal of the Paris Climate Accord is to limit warming to below 2 degrees Celsius and if possible to stay as close as close to 1.5 degrees above pre-industrial levels.  Nations around the world have made commitments to drastically reduce their carbon dioxide emissions from the use of fossil fuels that are in large part responsible for the rising temperatures.

There are a number of countries that proudly claim to be leading the world in the fight against climate change but who are actually still a major part of the problem.  Among these are Norway, the UK, and Canada.

Norway powers its streetlamps with renewables, runs its public transportation system entirely by renewable energy, and leads the world in the adoption of electric cars.  Both the UK and Canada have set ambitious targets for emissions reductions leading to zero net emissions by 2050. 

The problem is that under the Paris Agreement, each country is only responsible for the greenhouse gas emissions produced within its territory.  That means that the UK, Canada, and Norway (like many other countries) don’t need to worry about the emissions caused by the burning of their oil, gas, and coal in other places around the world.

Norway’s annual domestic emissions reached about 53 million tons in 2017 according to its government.  The emissions from the oil and gas Norway sold abroad reached roughly 470 million tons in 2017.  Canada has huge proven oil reserves it is exploiting.

Canada, Norway, and the UK all plan to keep producing fossil fuels, investing in new fossil fuel projects, and explorations.  As long as this continues, these countries are not really climate champions; they are climate hypocrites.

Another Hot November

January 3, 2020 By EarthWise Leave a Comment

This past fall saw yet more of the high temperatures the world has been experiencing in recent times.  Both the season (September through November) and the year to date were the second hottest in recorded history.  November itself was the second-hottest November in the 140-year global climate record.

The high temperatures were felt at both ends of the world.  Sea ice coverage across both the Arctic and Antarctic oceans fell to near-record lows in November.  Arctic sea ice coverage was nearly 13% below the 1981-2010 average, while Antarctic coverage was 6.35% below average.

The average global land and ocean surface temperature for November was 1.66 degrees Fahrenheit above the 20th century average.  The year-to-date global temperature was 1.69 degrees Fahrenheit above the 20th century average.  These numbers correspond to almost a 1-degree Celsius increase, which should be compared with the Paris Climate Accord goal of keeping that increase to no more than 1.5 degrees.

November was the hottest November on record for South America, Africa, and the Hawaiian Islands.  The Caribbean had its second-hottest November, and Europe had its seventh hottest on record.

The world’s average sea surface temperature ranked second warmest for the year to date and was only 0.05 degrees cooler than the all-time record.

The National Oceanic and Atmospheric Administration issues monthly global climate reports and for quite some time, these reports seem to all be the same.  Another new record for heat or at least another near record.  We have to expect that this trend will continue at least until the world starts making progress in dealing with its root cause.

Meeting Climate Goals With Current Energy Infrastructure

September 2, 2019 By EarthWise Leave a Comment

The Paris Climate Agreement set forth a goal to keep global warming below 2 degrees Celsius as well as a more optimistic (and preferable) goal of keeping the temperature rise to less than 1.5 degrees.  Reaching either of these goals requires getting to net-zero emissions by the middle of the century.

A new paper, published in Nature, looks at the issue of whether existing power plants and other fossil-fuel-burning equipment (including vehicles) can continue to operate until they age out of functionality, or whether they need to be retired early.

The results of the study are that future emissions from existing facilities would take up the entire carbon budget needed to limit warming to 1.5 degrees Celsius and almost 2/3 of the budget needed to keep warming below 2 degrees over the next 30 years.

So, the good news is that we can still avoid a 2-degree rise without having to shut down all the existing power plants early.  But we would definitely have to stop building new things with smokestacks and tailpipes that dump CO2 into the atmosphere. 

That good news is tempered by the fact that the number of fossil fuel-burning power plants and vehicles in the world has increased dramatically over the past decade, spurred by rapid economic and industrial development in China and India.  In fact, China is predicted to produce more than 40% of all the carbon emissions over the next 30 years.

The 2-degree climate goal is not at all the most desirable result.  The 1.5-degree target would be far better for the climate.  But if the world is to achieve it, there will be dramatic changes needed in the existing infrastructure – either shutting it down or retrofitting it to drastically reduce emissions.

Natural Climate Solutions Are Not Enough

April 1, 2019 By EarthWise Leave a Comment

A new policy perspective published in Science by researchers at seven prestigious institutions looked at the role of natural science solutions in stabilizing the Earth’s climate for people and ecosystems.   While they asserted that it is imperative to ramp up natural climate solutions, they also concluded that natural solutions alone will not be sufficient.

Natural science solutions include such things as enhancing carbon sinks from forests, agriculture and other lands.  Doing these things are very beneficial in their own right as they lead to improved forests, croplands, grazing lands, and wetlands.

However, these things will not be enough to meet the goals of the Paris Climate Agreement and must be combined with rapid efforts to decrease emissions from the energy and industrial sectors.  Among their various findings, the researchers warn that a ten-year delay in emissions reductions from these sectors could completely negate any potential benefits of natural climate solutions.

As has become increasingly clear, there is not an either-or situation with regard to the actions that need to be taken with respect to climate change.

Maximizing natural climate solutions and reducing emissions from the energy and industrial sectors will provide broad benefits beyond climate change mitigation.  Doing these things will improve forests and habitats, reduce the risk of wildfires, and decrease air and water pollution thereby improving human health and well-being.

Of course, to reduce cumulative emissions and put a cap on the warming of the planet, there will need to be policy mechanisms and incentives in place that support both natural climate solutions and increasing mitigation efforts across the energy and industrial sectors.

With the United States backing away from the Paris climate agreement and with Europe taking a less active role in climate negotiations, China has become the bellwether on global climate change.  Recent climate negotiations in Bonn, Germany were rather acrimonious as countries accused other countries of not doing their part or keeping their promises.

The Paris Climate Agreement embodies a commitment to hold the increase in the global average temperature to less than 2 Celsius degrees above preindustrial levels.  Most strategies to achieve this goal involve reductions in greenhouse gas emissions from human activities such as burning fossil fuels as well as various land use activities.  But there are also so-called Natural Climate Solutions, which relate to the storage of carbon and reduction in carbon emissions across global forests, wetlands, grasslands, and agricultural lands.

The Paris Climate Agreement seeks to reduce global carbon emissions.  The nearly 200 countries who signed it have pledged to reduce their own emissions within their borders.  And therein lies the rub:  the agreement says nothing about the impact their products have across the world.   For some countries, the problem is not so much the emissions they produce; it is those they export.
