Climate damage is worsening faster than expected, but there's still reason for optimism – 4 essential reads on the IPCC report | Political News

For example, many countries saw their transportation emissions drop during COVID-19 as more people were allowed to work from home. Bike sharing in urban areas, public transit-friendly cities and avoiding urban sprawl can help cut emissions even further. Aviation and shipping are more challenging to decarbonize, but efforts are underway.

He adds, however, that it’s important to remember that the effectiveness of electrifying transportation ultimately depends on cleaning up the electricity grid.

The IPCC reports discuss several other important steps to reduce greenhouse gas emissions, including shifting energy from fossil fuels to renewable sources, making buildings more energy efficient and improving food production, as well as ways to adapt to changes that can no longer be avoided.

There are reasons for optimism, wrote Robert Lempert and Elisabeth Gilmore, co-authors on the IPCC’s report focused on mitigation.

“For example, renewable energy is now generally less expensive than fossil fuels, so a shift to clean energy can often save money,” they wrote. Electric vehicle costs are falling. Communities and infrastructure can be redesigned to better manage natural hazards such as wildfires and storms. Corporate climate risk disclosures can help investors better recognize the hazards and push those companies to build resilience and reduce their climate impact.

“The problem is that these solutions aren’t being deployed fast enough,” Lempert and Gilmore wrote. “In addition to pushback from industries, people’s fear of change has helped maintain the status quo.” Meeting the challenge, they said, starts with embracing innovation and change.
