Carbon Capture: Solution Or Band-Aid? | Earth Wise

July 13, 2022 By EarthWise Leave a Comment

Can carbon is part of the solution to climate change

The idea of capturing the CO2 emissions from industry and locking them up is nothing new.  It’s been going on for decades in some places.  Norway’s state-owned oil company Equinor has been holing away a million tons of CO2 a year for a long time.  But overall, CCS – carbon capture and storage – has had very limited use.  As of last year, there were only about 30 large-scale projects in operation around the world, capturing only 0.1% of global emissions.

There is now growing interest in CCS and many new projects are underway.  A combination of rising carbon prices in Europe, tax breaks for CCS in the US, national net-zero targets, and the increasing need to ramp down global emissions are all driving rising CCS activities. 

While recent reports from the Intergovernmental Panel on Climate change still claim that it is possible to remain below 2 degrees Celsius of warming without using carbon capture, there is growing belief that it may be necessary given the present pace of the transition away from fossil fuels.

Two industries that together produce about 14% of global CO2 emissions are cement and steel.  These are both industries for which it is difficult to eliminate emissions regardless of the energy sources used. CCS may be the best approach to reducing their emissions.

But there is considerable pushback against CCS.  The concern is that CCS is primarily a way to delay decarbonization.  It encourages various industries to continue to use fossil fuels instead of shifting away from them.  Nonetheless, CCS no doubt has its place as part of the solution to climate change.

Fall Safety Tips | Earth Wise

November 4, 2020 By EarthWise Leave a Comment

Tips for fall safety

The fall season has its own weather-related hazards, such as raging wildfires across the West and a busy hurricane season in the Atlantic.  There might even be snow in some places.  The National Weather Service issued a set of four broad safety tips for being prepared for the dangers of fall weather.

With regard to wildfires, it is important for smokers to properly discard cigarettes, for people to avoid activities with open flames or sparks, and to use fire-resistant landscaping around our homes. The Weather Service issues Red Flag Warnings when conditions are ripe for wildfires.

In this busy hurricane season, even people who don’t live in hurricane surge evacuation areas need to know their home’s vulnerability to damage from high winds and inland flooding.  People should have a plan that includes an emergency kit and a safe place to shelter should they need to evacuate.

It is important to have a plan in case strong winds pose a threat.  When preparing for an extreme wind event, secure objects that can be tossed or rolled, trim trees near homes, and have a plan in case of an extended power failure.  Strong winds can even happen on a clear day.

The key advice in case you encounter flood waters is “turn around, don’t drown.”  It is never safe to walk or drive into a flooded roadway.  It is best to delay travel until roads are clear.

Fall can be the most beautiful season of the year, but it also has its dangers.  Following advice such as that provided by the Weather Service is prudent and potentially life-saving.

Cold Weather In A Warming Climate

The climate is warming.  The average global temperature is going up year after year, bringing about significant changes to weather around the world.  But the fact is that these changes don’t always lead to warmer weather.  And ordinary variations in local weather can also go in either direction.
