Over the last year, we have seen many energy and climate records broken, which has brought both encouraging and disturbing news.
The year 2023 was the hottest on record, with climate scientists attributing this to a combination of long-term human-induced global warming and natural variability. Alarming records in climate-warming pollution were also set, as human activities increased carbon dioxide levels in the atmosphere to nearly 420 parts per million, a level not seen in 14 million years. The National Climate Assessment highlighted the widespread effect of these changes across the United States, stressing the critical need for more effective emissions reduction policies.
Despite these troubling patterns, there is a bright spot. Many countries are taking steps to reduce climate pollution, providing hope for 2024. The passing of the Inflation Reduction Act by Democrats in 2022 represented a watershed moment. In 2023, this legislation intended to promote clean technologies such as solar panels, heat pumps, and electric vehicles began to provide positive benefits. Climate pollution in the United States was reduced by 2-3% compared to the previous year, while emissions in the European Union were reduced by 6-7%.
However, emissions in China and India increased, which can be attributed in part to China's recovery from its "zero-COVID-19" program. Global carbon pollution graphs revealed an alarming increase in China's emissions, compared with minor declines in the United States and Europe.
In 2023, clean technology saw tremendous global expansion, particularly in China. Solar panel installations in China surpassed the previous year's record by more than 50%, while wind turbine, heat pump, and electric car sales also set new records. This trend is expected to accelerate in 2024, with 118 governments pledging to triple global renewable energy capacity by 2030 and 155 countries promising to reduce methane emissions by at least 30%.
China's accelerated deployment of solar panels and wind turbines may result in a reduction in carbon pollution in 2024, putting 2023 as the year when global climate pollution peaked. In the United States, the Inflation Reduction Act's financial incentives are projected to stimulate wider deployment of clean technologies, with rebates for homeowners and tax credits for electric vehicles going into effect in 2024.
Despite the possibility of an El Nino event breaking global temperature records in 2024, the year holds promise as a turning point for our energy systems, carbon pollution reduction, and the future of Earth's climate.
