No. JFK's lowest May temperature is 34° (May 10, 1966 and May 9, 2020).

The fossil fuel industry has warped political and public opinion. It is the beneficiary of $7 trillion in annual subsidies according to the IMF's 2023 report and earns tens of billions of dollars in annual profits. It wants to burn through all fossil fuel resources to maximize the lifetime profits possible from such an outcome, especially as it is not required to pay for any of the damage it inflicts from climate change and its impacts. As a result, it has devoted funds and effort to undermining public understanding of the consequences of its injecting enormous amounts of greenhouse gases into the atmosphere each year. The information ecosystem is deficient to the challenge. Social Media has few if any checks on disinformation, hence climate denial continues to prosper there. Unfortunately, a growing share of the public obtains some or most of its information from Social Media. Even the mainstream media with a few exceptions, devotes very little coverage to climate change. For example, aside from a handful of outlets, none connected the recent rains in Dubai/UAE to climate change despite climate modeling calling for an increased frequency of excessive rains in that region, very few noted that the recent extreme heat in Africa's Sahel Region would have been "virtually impossible" without climate change, and few if any have connected the raging heatwave across south Asia to climate change despite a 2023 attribution paper that covered a similar and somewhat lesser April heatwave there. This material omission from sources of information, including credible sources, further undercuts the urgency of addressing climate change at a time when a still relatively smooth transition is possible. By 2030, the transition required to hold warming to 1.5C to 2.0C will be fairly disruptive and painful. By then, policy makers will likely claim that the required changes are "unrealistic"--that the required changes will become drastic would be the payoff on decades of relative policy inaction. Younger people's and future generations' wellbeing would be sacrificed on the altar of fossil fuels and shortsighted status quo thinking. Finally, even as a number of countries are rapidly expanding their clean energy infrastructure/capacity, those countries are avoiding setting targets for rapidly phasing out fossil fuel burning. In fact, oil and gas production is growing, not shrinking. For all the political rhetoric, the U.S. is a big reason global oil and gas production is increasing, not falling. From the EIA: Although forecast OPEC+ crude oil production in 2024 decreases by 0.9 million b/d compared with last year, forecast production outside of OPEC+ increases by 1.8 million b/d, led by the United States, Guyana, Brazil, and Canada. Global liquid fuels production in our forecast increases by 2.0 million b/d in 2025 as the OPEC+ production cuts expire and supply growth outside of OPEC+ continues to grow. An "all of the above" energy approach is a guarantee that the world won't meet its Paris Agreement commitments.

No. The record was set on May 9, 1977 with a high temperature of just 43°.

2.9C is still avoidable. Whether it will be avoided remains to be seen.

One day, younger voters will be the largest share of the electorate. And if they face a materially worse climate, they may well choose abrupt breaks from existing policy arguing that failed leaders from past generations left them no other choice. Today, transitions are still possible, though the rate of needed change is much greater than it was 10-20 years ago on account of relative policy inaction. For now, the world remains on a course where it will be 2.9C warmer by 2100 (higher if Hansen is right).

Under mainly cloudy skies, much of the region struggled to reach the low 50s. Tomorrow will be somewhat milder, but generally cooler than normal conditions will likely persist through most of the week. It could turn warmer as April concludes with May starting with warmer to much warmer than normal temperatures. The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +1.15°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring. The SOI was -4.33 today. The preliminary Arctic Oscillation (AO) was -0.594 today. Based on sensitivity analysis applied to the latest guidance, there is an implied 74% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 54.9° (1.2° above normal).

Some actually are on the front lines e.g, NASA’s Peter Kalmus. The news media covers even trivial entertainment and business developments (small scale impact) and devotes very little coverage to climate change and related events. Perhaps an extreme heatwave in Paris that coincided with the summer Olympics would bring worldwide coverage. In the meantime, the fossil fuel industry continues to dump greenhouse gases into the atmosphere, receive trillions of dollars in subsidies, and inflict growing harm on human health/lives and ecosystems.

Tragically, society tolerates their dishonesty.

Despite the rapid arrival of clouds, spring is in all its spectacular glory at the New York Botanical Garden.

My guess is that we'll see the temperature reach 90 or above at least once during May.

The temperature did overperform today. At NYC, it was 2 sigma above the forecast high. However, it does seem that busts more often than not occur when temperatures are higher than forecast. It's tough to know whether on a day-to-day basis, the warming climate is playing a role. But on a weekly or longer scale, the warming climate has contributed to outcomes winding up generally above the modeled forecasts.

Sunshine returned this afternoon boosting regional temperatures into the 60s. Some locations, including New York City, Newark, and Philadelphia reached 70° or above. Cooler air is now overspreading the region on a gusty breeze. Generally cooler than normal conditions will likely persist through most of next week. However, the cold won't be exceptional. It could turn warmer as April concludes with May starting with warmer to much warmer than normal temperatures. The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +1.15°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring. The SOI was +5.33 today. The preliminary Arctic Oscillation (AO) was -0.246 today. On April 14 the MJO was in Phase 4 at an amplitude of 0.520 (RMM). The April 13-adjusted amplitude was 0.553 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 80% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 55.1° (1.4° above normal).

I suspect some of the interest can be seen in severe weather discussions and tropical cyclone discussions. Commentary seems to drop off when it comes to heat, probably because a lot of people don't like it. Nevertheless, heat is an important topic for discussion.

For NYC:

Probably by summer.

Tomorrow will see temperatures briefly return to near seasonable levels. However, another cold front will likely cross the region with a return to cooler conditions to conclude the weekend. Overall, generally cooler than normal conditions will likely persist through most of next week. However, the cold won't be exceptional. It could turn warmer as April concludes with May starting with warmer to much warmer than normal temperatures.

For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +1.15°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring. The SOI was +12.18 today. The preliminary Arctic Oscillation (AO) was not available today. On April 14 the MJO was in Phase 4 at an amplitude of 0.520 (RMM). The April 13-adjusted amplitude was 0.553 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 74% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 55.0° (1.3° above normal).

Not just New York City: At Caribou, where winters have warmed 2.9°F over the past 30 seasons, nearly 1-in-3 winter days has been 10°F or more warmer than normal since 2020.

Temperatures will rebound into the upper 50s tomorrow under partly to mostly cloudy conditions. Saturday will see temperatures briefly return to near seasonable levels. However, another cold front will likely cross the region on Saturday with a return to cooler conditions. Overall, generally cooler than normal conditions will likely persist into at least the middle of next week. The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +1.15°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring. The SOI was -5.77 today. The preliminary Arctic Oscillation (AO) was not available today.

Climate Model Forecasts for Future Winters for RCP 4.5 (most likely scenario):

The report didn't mention a synergistic heat wave.

While some on Social Media continue to dismiss or deny climate change, real world evidence of the consequences of anthropogenic climate change continue to pile up in a growing body of attribution studies. The latest study concerns an extreme heatwave that affected Africa's Sahel Region from March 31-April 4, 2024. The magnitude of the heat was assessed as having been "virtually impossible" in the absence of climate change. Moreover, as the climate warms further, the frequency of such heat is expected to increase dramatically, with such events become a once-in-20-year case. The full attribution study can be found at: https://spiral.imperial.ac.uk/bitstream/10044/1/110771/2/Report 1.pdf

The above table was broken down into decadal periods:
