NH: My background is in meteorology, geosciences and interdisciplinary studies. I have a Bachelor of Science in Interdisciplinary Studies from South Dakota State University. I completed a Master of Science in Geosciences with a concentration in Applied Meteorology from Mississippi State University in 2016. My education and research studies have been in the societal impacts of weather/climate, natural hazards, and advanced forecasting techniques. I also have a background in global climatology. I did undergraduate research into human decision-making in response to tornado warnings and graduate research in tropical cyclone impacts.

ML: What is the most disturbing aspect of anthropogenic global warming that you are seeing today and what are its implications for the future?

NH: To me, the most disturbing aspect is the destruction of ice on the planet. It is commonly discussed among climate scientists that the planet has a high “inertia”. This means in natural climate change, there is typically a significant lag between what is happening in the atmosphere (rise in greenhouse emissions) and climate response (warming of the planet), forcing a more gradual temperature rise.

Trends in sea ice thickness are another important indicator of Arctic climate change. While sea ice thickness observations are sparse, here we utilize the ocean and sea ice model, PIOMAS (Zhang and Rothrock, 2003), to visualize mean sea ice thickness from 1979 to 2019.

ML: With the environmental damage that has already been put into the pipeline, modern organized human society may not survive this century and we are already seeing signs of this with the destruction caused by recent extreme weather events. The city of Beira in Mozambique, recently hit by Cyclone Idai, is said to be “the first city to be completely devastated by climate change.” Do you think it’s possible to transition to a net-zero carbon emission civilization within a brief period? Would this not require a radical reconfiguration of every sector of our economy and the way in which we treat each other and the environment?

At 500 parts per million of equivalent carbon dioxide concentration, enough greenhouse gases are currently in the atmosphere to ultimately warm the planet 4-5 degrees C/7-9 F above 1700s temperatures, raise the sea level by 220 feet/67 meters (assuming 1 ppm CO2 equivalent = 1 ft sea level rise, based on past longer-term paleoclimate change response), remove significant amounts of soil moisture, leading to the destruction of agriculture. And this is without any other carbon releases or feedbacks. Building more in an attempt to maintain civilized society with high energy consumption makes this all worse.

ML: There are around 454 nuclear reactors around the world with several dozen more currently under construction. At least 100 U.S., European and Asian nuclear power stations are built just Shimano Dura-Ace PD-7800 SPD-SL Pedals. With accelerated sea level rise and stronger storms on the horizon, we should be planning right now to decommission and close down these future nuclear disasters. What is your stance on nuclear energy?

We are entering a range of weather conditions not supportive of agriculture. And not simply monoculture. All agriculture. Even other ways of doing Ag require stable weather conditions, seasonality, soils and ability to conduct economic activity between peoples. None of this will be possible in these conditions. And that assumes the ecosystems which support agriculture also remain stable and available and that is not likely given the ongoing global extinction of insects.

While climate models incorporate important climate processes that can be well quantified, they do not include all of the processes that can contribute to feedbacks (Shimano Dura-Ace ST-7970 Di2 Electronic Shifters 10 Spd. Left & Right NEW), compound extreme events, and abrupt and/or irreversible changes. For this reason, future changes outside the range projected by climate models cannot be ruled out (very high confidence). Moreover, the systematic tendency of climate models to underestimate temperature change during warm paleoclimates suggests that climate models are more likely to underestimate than to overestimate the amount of long-term future change (medium confidence).

In a new ominous research finding, the evil twin of climate change(Shimano Dura-Ace WH-7900-C50 Road Bike Wheel Set Carbon Tubular 700c 10 Speed) is threatening the base of the marine food chain by disrupting the production of phytoplankton. This is yet another positive feedback loop increasing the rate of global warming. Climate feedback loops and ice sheet modeling are two weak areas of climate science, which means many unpleasant surprises. This is why researchers are constantly astonished. Adaptation is not a luxury most organisms have at the present rates of change. Techno-fixes are but a Shimano Dura-Ace XTR CN-HG901-11 HG-X11 11 Speed Chain ICNHG90111116.

A diet reliant on animal agriculture is one of the largest contributors to greenhouse gases, biodiversity loss, and Shimano DXR Front BMX Bicycle Hub - HB-MX71 (36H - 100mm OLD), yet global per capita meat consumption is increasing rapidly in both developing and industrialized countries.

Coca Cola alone produces 110 billion throwaway plastic bottles every year – an astounding 3,400 a second. Shimano E-tube EW-JC130 Y-split cable, 3 connectors, 550 mm 50 mm 550 mm is another massive contributor that cannot be overstated. Half of all plastics have been made in just the last thirteen years. Over 90% of the so-called purified bottled water sold to the public has been shown to be contaminated with hundreds and even thousands of microplastic pieces. A byproduct of petroleum and the epitome of our throw-away society, plastics have truly become Shimano EW-JC130SS Di2 E-Tube Wire, Y-Split, 50 520 520mm, entering the Shimano EW-WU111 Di2 E-Tube Bicycle Wireless Unit - IEWWU111A at every level.

A study published last year pulls no punches by describing the mass extermination of billions of animals in recent decades as a “biological annihilation.” Extinction risks for many species are Shimano Exage 400EX SIS 7 Speed Light Action SL-A400 M5 Shifting Leves NOS.
