Planet warming is accelerating

Global temperatures are on the rise, shattering numerous records in 2024. It appears we’ve already surpassed the critical 1.5°C threshold set by the Paris Agreement, much earlier than climate models anticipated. With this acceleration in warming, we’re seeing the onset of more extreme weather worldwide. The essence is simple: greenhouse gases trap more energy on our planet, leading to higher temperatures, which in turn fuel weather events.

Charts illustrating this trend are unmistakable.

A Timeless Warning: Carl Sagan on Climate Change 40 Years Ago

Check out this insightful video from Carl Sagan in 1985, which offers a crystal-clear explanation of human-induced climate change. This isn’t new; experts tried to warn us more than 40 years ago.

Individual efforts to cut down on fossil fuel use are important, but we must also rally for larger systemic changes. It’s time to hold governments and corporations accountable for decarbonizing the economy. Vote for policies and politicians that prioritize climate action. #ClimateActionNow

To put it in perspective, the Intergovernmental Panel on Climate Change (IPCC) released its first report in 1990, five years after Sagan’s video. That report already indicated that human activities were likely affecting global climate. We can’t say we weren’t warned.

Climate cartoon of the week

Just saw this spot-on cartoon by Ruben Bolling, and I had to share it. It brilliantly shows the grim reality of climate deniers, a topic I dug into just a few days ago. Check out my previous post here.

Climate Denial: Unmasking the Hoaxers, Libertarians, and Indifferent Majority

As an active climate change activist, I’ve been arguing with climate change deniers for a while. Through these often painful and frustrating experiences, I’ve learned that not all climate deniers are cut from the same cloth. So, I decided to identify some key profiles.

Cartoon timeline of climate denial by oil companies, from 'climate change isn't real' to 'it's real but not caused by humans' to 'oops'.

For those unfamiliar with the term, climate deniers are individuals who reject the scientific consensus that global warming and climate change are happening and are being caused by human activities, mainly through the use of fossil fuels. Unfortunately, and quite shockingly, there’s no shortage of climate deniers out there. It’s essential to recognize that most climate deniers are likely victims of misinformation, often stirred up by the oil sector and other groups eager to maintain the status quo.

Climate Action Simplified: Thoughts for Non-Experts

Recently I was asked the following question in a chat group of former colleagues. I wrote the response below and thought I would share it with you.

Question: “Diego, based on what you’ve studied, what are the 3 things that need to be done to halt/stop/reverse global warming? The question is simple, but there’s so much noise on the topic that it seems difficult to discern the ‘indicated actions’.”

A Tale of Two Stripes: Interpreting the Colors of Climate Change and Biodiversity Loss

Warming stripes showing global temperatures shifting from blue (cooler) to red (warmer) years.

At first glance, you might mistake this image for modern abstract art. Strips of shifting colors, each telling its own story. However, they represent a stark reality that’s impacting us all. In fact, out of my concern for our planet, I’ve been using the climate stripe as the banner image for this blog for several years.

CO2 reached 420 ppm in the atmosphere

Humanity continues consuming fossil fuels and carbon dioxide (CO2) continues accumulating in the atmosphere. For the first time, the level of 420 ppm was reached in 2022. The following charts show clearly how humans have caused this.

Chart of carbon dioxide in the atmosphere over the past 800,000 years: never above 300 ppm until the recent spike to 419 ppm.
